2001 Chevrolet Silverado 2500, Fuel Injector Replacement

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik repairing vehicles in Vancouver for close to 40 years. And he's the owner. The big boss at Pawlik Automotive in Vancouver. They are 24 time winners of best auto repair in Vancouver as voted by their customers. They didn't just make it up. They won it. And of course they're the best auto service experience in Vancouver. We're talking cars. How are you doing Bernie? 

Bernie: Doing went very well. 

Mark: So today's victim, we're reprising a 2001 Chevy Silverado 2500 that this time needed fuel injector replacements. What was going on with this vehicle? 

Bernie: Yeah, so this is the same truck we talked about in our last podcast where we replaced the injection pump. And unfortunately the injection pump repair didn't go quite as well as we'd thought. We delivered the vehicle to the customer on Friday after lengthy road tests. And everything seemed to be fine only to find it back on Monday with the crankcase still filling up with oil and kind of disappointing for everyone that that happened because we hate it when a job doesn't go well. But we had kind of speculated on this job that the injection pump needed to be done because a previous shop had changed the injectors and apparently verified all their work. So that's what we were faced with next. 

Mark: So what was your next step? 

Bernie: Yeah, so the next step was to call the owner of the vehicle and just have a good chat with them and say, okay, so tell us about the injectors that were put in, you know, what did the shop do? So is a bit of a learning curve for us. You know, we made some assumptions that the shop had done some good work and as it turned out, we found out that the injectors that actually have been supplied to the shop by the owner who'd ordered them online at a cheaper price. They're supposed to be Bosch rebuilt injectors. But they weren't as it turned out to be.

So at this point we figured, okay, the injection pump we bought from a reputable supplier, we never ever have a problem with their parts. So we figured, okay, at this point, obviously something at the other shop did, they didn't either know what they're doing or they overlooked something.

Or now the fact that they didn't actually supply the injectors and we didn't know what the source was, you know, they could be faulty. So our next step was to basically remove the valve cover. And figured, okay possibly leaks from the return line system. So we connected a smoke machine up, we figured this is the easiest way, we ran some air pressure through it. Didn't find any leaks. We hooked our smoke machine up, found no leaks. A smoke machine will pump smoke through a line or a pipe or wherever we send the smoke. And it'll show as a leak, which is a great way to find leaks, nothing showed up. So we verified the injection lines and the pipes were all in good shape.

I'll just pop up some pictures and we can keep talking.

But this is basically the view under the valve cover. What you're looking at here, these are the rocker arms. So that's part of the valve train. This is a fuel injector here. There's four of them per side. It's a V8 engine. The red arrow points to the fuel injection return pipe. And the yellow basically points to the bolt where this attaches to the fuel injector. And there's two copper washers on each side. So these are potential leak points. And these pipes actually go to the valve cover housing. There's plumbing that connects them up to the fuel return system. So, and again, you know, we tested with a smoke machine, verify that there's no leakage in this particular area. So that's kind of where what our next step in her testing was. 

Mark: So no leaks in the return system and what was next? 

Bernie: So what was next was basically, okay. There's no leaks there. We know the injection pump. We assume that that's gotta be good. So we authorized the client to remove the fuel injectors and send them off to our, I'll just name the name of our supplier, NW Fuel Injection. They're out in Surrey. If you're in the Vancouver area and if you actually are a do it yourselfer diesel person, we don't do these podcasts for that, but you are, this is the best place to buy your diesel parts from because the quality of their work is absolutely superb and everything they sell is good quality, high-end. You know, it's already OEM Bosch remanufacturer. They do some remanufacturing themselves, but I've seen their equipment. It's state of the art. 

Anyways they have injection testing. So we sent the injectors off to be tested and that revealed some very interesting things. And then actually in fact, found the problem. So I will...

Mark:  What did they find? 

Bernie: What did they find? Well, we found a very badly leaking fuel injector. First thing I'll do, and this is kind of boring writing, but I'll just leave this up on the screen for a minute, but I'll just talk it through. So they, they basically tested all eight injectors and they said, you know, five of them passed.

They all tested perfectly within factory specifications. Number two, injector failed. Significant over fuel at pre injection and pilot ignition injection. 28% above factory specifications. So that isn't going to leak fuel into the engine, but that is going to cause the engine not to run properly and the tests they do, I didn't show all the test reports, I don't have them on this podcast, but there's certain injection sequences is I believe there's five of them on these injectors. So they test every one of them. 

So number five, fail. Under fuel at full throttle, 4% below factory specs. I mean, that's really pretty minimal. You'll probably never notice that unless you're full throttle and even then you'd probably notice it. Then number seven, fail, leaking, at body. And this is the interesting thing which we'll show a video in a second. You can see what was going on. And then we found out why this crank case is filling up so fast with diesel fuel.

The other interesting line is the injectors are not genuine Bosch, which is obvious from the fact that they have no Bosch identifying numbers on the top. So, you know, we could've just put five of the injectors back in sold three more, but you know, once you get into this, the suppliers questionable, how long are these injectors going to last? There's three already failed and they're brand new. Theoretically brand new. 

So I'm going to get into the video which is the fun part. And if you watch this video, if you look around this area here where I'm running my mouse, you'll see everything is dry and you'll notice fuels starts to pool up and then it eventually starts spraying out in rather large quantities. It's a 20 second video, so just kind of watch carefully. I'll play it a couple of times.

You can already start to see some fuel pooling in this area here, which should it be none. Now there's a huge drop up there and now you can see it just spraying out all over the place. I'll just play that last few seconds of the video because this is the interesting part. Right there, you can see field spring out. Well, you can imagine running an engine and It wouldn't take long for a litre to get sprayed out after an hour's driving, maybe, you know, a few litres in an hour or so. There was our problem.

Mark: So, what happened next?

Bernie: So we replaced the injectors, the owner was kind of reluctant because he'd spent an awful lot of money on this vehicle already. And it kind of put us in a bit of a sticky spot because, you know, we'd said to him, look, you know, based on what you've told us, this is where we should proceed. And the injection pump wasn't a cheap job. So we did ended up compensating him and reducing the cost on the job much lower than we would have normally done on doing a set of injectors. But we did them and you know, it was good that he did them. We put them in and buttoned everything up and fired it up. And you can ask me the next question.

Mark: So how did it work after that?

Bernie:  Really, really good.  It was amazing because you know, the week before this vehicle is here for a couple of weeks, but after we'd done the injection pump, I remember taking it out for a good long road test. And I seem to remember it ran fairly well, but by the time we got back on the Monday, maybe because it was the crankcase was so full of fuel, it really ran badly. Felt like it was only running on seven cylinders. And you know, when we changed the injectors with the pump done, this vehicle ran like brand new. And I, I say that because I actually bought a brand new Duramax six months ago. And so I know exactly what a new one feels like and this truck, you know, 20 years old ran exactly like a brand new truck. Tons of power, pep, acceleration, no smoke. It was just a dream to drive. So ran great and we drove a extra long time. Triple checked to make sure the oil wasn't too full. And you know, there was no stored trouble codes related to any injection issues. 

And we did get a call back from the customer a few days later, he said he was super happy with the way it worked. So it's a happy ending. And I guess the good news, the vehicle did have a fair number of ks, two to 300,000 kilometre range, which is a fair amount of mileage. So changing injection pump was not a bad thing to do anyways, but it's too bad we didn't think of the injectors as a first thing, because that probably would have  saved a little bit of money for him.

Mark: There still was a leak in the injection pump, you saw that.

Bernie:  There was a leak in the injection pump, which we could see, but it wasn't really major compared to this injector and who knows. I mean, given time, maybe over a period of a couple of months, maybe it would have started to fill a crankcase up. So there was a leak, but certainly not to the severity of the injectors. 

Mark: So what have we learned? Don't use cheap parts. Use good stuff and use the place that's knows what they're doing, frankly, is going to question you on it, but also this is really important to keep a log of what actually has happened. What have you done? Don't try and hide anything from your service guys. Tell them the truth about everything that's gone on so they can fix your car, right the first time. 

Bernie: Exactly. Exactly. You know, people sometimes, you know, we often have to pry information out of people and I think people don't often think, well, maybe that's not important, but it is important to say, Hey, I bought this from this particular place. And you know, I think what we've learned as a shop is to really ask questions. 

 If you look back one of our other podcasts, we had a client with a Land Rover LR2 had a bunch of engine drivability issues that we solved. And in the end I ended up making a project. I go, look, I just want to fix this vehicle. So it was one of those things where we didn't charge them fully for the amount of time we spent on it. I just educated myself. And finally, at the end of the day, thought, he changed the fuel injectors. Where'd you get them from? We bought some cheap fuel injectors from somewhere.

And so you know, had he not done that he would have saved himself thousands of dollars on, literally thousands of dollars on, at least a couple thousand dollars on repairs and grief. You know, so. If you're buying parts, don't buy the cheap stuff, but if it's OEM and you know it, for sure, and it's cheaper that's okay.

But don't buy parts from someone who hasn't got the backing of a major manufacturer because you're just asking for trouble. 

Mark: And if you don't know, go to a shop that does know.

Bernie: Exactly, exactly. And bring all the information, lay your cards out on the table. Hey, you know, here's where I had it fixed. Here's the work I had done. I supplied the parts and this is actually another reason why we don't like to do work with customer supplied parts, because these are the kinds of issues we run into. You know, we bring it to us to do the whole job. Yes, you'll probably pay some more money. We guarantee the whole thing. Now, for this guy, if he has fuel, leaking into a system, We also changed all those fuel return pipes and seals and everything. If there's any leaks, we own that job now for the next couple of years. 

Mark: They have a warranty basically. 

Bernie: We have a warranty. Yeah, yeah. We back it. 

Mark: Sometimes ladies and gentlemen, let me give you the sad news. Sometimes the internet and Amazon are not your best place to get parts for your vehicle. 

Bernie: Exactly. Sometimes it is. And I will say something about prices and I don't, we should shoot Amazon, but you know, sometimes the price on Amazon, a lot of times, they're really good. And other times they're outrageously overpriced too. So it's like anything buyer beware. You got to know what you're buying. Not Amazon's fault. You gotta be a good consumer and just look into your stuff.

2016 Toyota Highlander Hybrid, Brake Replacement

Mark: Hi, it's Mark from Top Local. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 24 time winners, best auto repair in Vancouver as voted by their customers. And we're talking about a Toyota Highlander. There can only be one. How you doing Bernie? 

Bernie: Good. I'm good.

Mark: So this is a 2016 hybrid. What was going on with this Toyota? 

Bernie: The owner had some concerns with the brakes. They were making some noises and it didn't quite feel right. So he brought it in for us to have to look at the brakes. 

Mark: So what kind of inspections do you do to check what's going on with the brakes?

Bernie: We have a standard brake inspection that we do for anyone who needs the brakes looked at. And so that entails of course, a road test as a first thing to see if there's any noises, see how the brakes feel. Of course, if the pedal's straight to the floor, and there are no brakes, we don't go on the road test, but that's not very common, fortunately. Because then the road test happens after we do the hoist inspection. So we go on a road test then do a hoist inspection. We remove all the wheels, look at the brakes in detail, measure the thickness of the brake pads, the rotors, test to make sure that things are moving. Look for leaks, inspect the brake fluid, look at the hoses, lines and all those kinds of things. And it depends from vehicle to vehicle. I mean, on an old car, that's perhaps from, you know, more salt prone areas we'll look at a little more detailed the brake lines than we would on say like a 2016 Highlander that's, you know, lived in British Columbia, like Vancouver area, all its life. It's only five years old. 

Mark: What kind of stuff did you find? 

Bernie: Yeah, so on the road test, we noted that there's some grinding sounds. The brakes felt like they're shaking a bit, possibly warped rotors. We found on the front brakes one side of the brake pads were worn down to two millimetres, which is basically worn out. And the other side, they were seven millimetres, which is an enormous difference. I mean, seven millimetres is, you know,  still has 60% of the brake pad life left. Two millimetres is basically worn out. On the rears, they were down to about the four to five range, so almost worn out, but then the rotors were also pretty rusty.

I mean, the brakes looked like they'd probably been on here for a long time. Let's get into some pictures here and we can have a look at what we found. 

So there's the Highlander hybrid.

The vehicle as far as the brakes, let's have a look at some of the old brakes. This is a front brake. Not really looking too much in the pads, but you can see the edges of the rotors are starting to rust, which is kind of normal wear and tear after a while. It indicates that these brakes have been on the car for a long time. Unless of course you're in somewhere climates like rustier than then they get worse.

And again, you can see here that the edges of the rotors are very rusted, which indicates they'd been on long time. Not severely rusted though, if in certain areas of the country and we even see it here, sometimes the actual surface will start getting badly rusted and you know, that's definitely not a good thing, but you know, easily replaced.

So just looking at what we repaired, new calipers, rotors, pads in the front you can see everything's nice and clean and fresh services. We lubricate everything with the special brake lubricant, which keeps squeaks and squeals to a minimum, and just keeps everything moving to keep maximize the life. And the rear brakes, did pads and rotors, caliper was okay. So we left that. So I'm kind of jumping ahead to the repairs we did. But we can talk about that some more in detail. So there's our picture show.

Mark: So you replaced everything basically in the brakes? 

Bernie: We did. Yeah. So what causes the breaks to be seven millimetres on one side and two on the other, it's basically a seized caliper, 99% of the time you can get a brake hose where, sometimes a brake hose will develop a blockage and it'll you know, restrict the flow to one direction. So that can happen. 

But on a 2016, basically a five-year vehicle, you'd never find that. It's only something that would happen on a, maybe 10 or 20 year old vehicle, but never on something that's five years old. It would be very unusual. So basically the caliper was seized on one side, causing the brakes to wear out much quicker and on the rear, as I mentioned, there's like four to five millimetres.

I mean one or two millimetre difference is no big deal. We test the calipers when we do the inspection and make sure that everything's moving freely. So the rear brake calipers were serviceable and all good. 

Mark: So why would that caliper freeze on and cause that one brake basically to do most of the work.

Bernie: Well, a couple of things. You can get corrosion, like moisture that intrudes inside the caliper piston, and that causes it to rust. And then seize up. Also the calipers have a sliding portion and they usually have pins that allow the caliper to slide back and forth. Some brake calipers have pistons on the outside and inside, and they don't have any slider pins. So any sticking in that area would either be a pad stuck where the pad slides, I call them pad sliders, the pad sliding area. But there's a few things.

The pins can seize up as well. On this type of caliper, it has an inner piston and pins that allow it to slide. So those seize up as well. And you know, they can be serviced and cleaned. That's a little easier to fix, but once they get really severe, it's better just to change the whole caliper.

Mark: So hybrid vehicles because of the recharge, I guess depends on kind of hybrid whether it's recharging or not, or do they all recharge? 

Bernie: Most of them, yeah. Regenerative braking. I mean, Toyota, certainly do.  

Mark: So that brake, because of the regeneration, the brakes aren't being used as much, shouldn't these brakes last a lot longer than this?

Bernie: Well, you'd think so. I mean, five years is not that old, but this vehicle does have 145,000 kilometres. So that's actually a fair bit of mileage. So I assume looking at these brakes that they were original and that kind of makes sense for hybrid, 145 Ks is pretty good. But you could still get 200. I mean, that's why taxis, they love Prius's because they're reliable. And the brakes last a long time. Like a typical taxi, they'd only get three months out of a set of brakes on a conventional vehicle. Three months on, you know, most people complain when they have to do their brakes every three or four years but on a taxi it's like every three months, but that takes a car off the road for a few hours. So, I mean, with a Prius, they can get a year out of a set of brakes. So that's a big, it's an enormous change. So, yeah, I mean, I'd say 145 Ks is a pretty good amount of time. And had this caliper no seized, these brakes probably would have lasted substantially longer.

Mark: Right. Is there anything that a Highlander or a vehicle owner can do to maximize their brake life? 

Bernie: Yeah, absolutely. Having the brakes serviced every couple of years on a vehicle like this is really critical, especially on a hybrid, because again, the brake pads lasts a long time. You can do a brake inspection after a year or two and go, oh, well, there's still like, you know, 10 millimetres left on the front brake pads. A couple of years later you look and there's like nine and you know, they're barely wearing, but it's a good idea to take them apart. Clean them lubricated with that type of lube we use, take the pad slider pins out, clean and lubricate everything. That keeps the breaks lasting a lot longer.

And if he did that kind of service, you'd probably easily get 200,000 or at least a hundred and probably another 50,000 out of a vehicle like this. Of course, you know, the edge rust on those rotors, you can't really do a lot about that. I mean, you could machine them, but it doesn't really make a lot of sense to do that. You're kind of taking material off the brakes and, you know, as long as they're not grinding and making weird noises, I would probably just service them every year or two. And you should be fine.

Yeah. So how are Toyota Highlander hybrids for reliability? 

They're legendary. Yeah, no, they're awesome. I think they're, older Highlanders did have some issues with inverters. I mean, this is a 2016 as much newer than, you know, I'm thinking like, oh, eight, seven, you know, like older. This is a newer generation. I mean, that far as I know, there's no problems with them. You know, a 145 Ks out of a set of brakes is pretty good. You know, it's a good vehicle.  I can't find any fault with it. Excellent.

2001 Chevrolet Silverado 2500, Diesel Injection Pump Repair

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, nigh on 40 years of fixing vehicles in Vancouver. And of course, he's the owner, the big boss behind Pawlik Automotive in Vancouver, 24 time winner, 24 time winners of best auto repair in Vancouver as voted by the customers. And of course Vancouver's best auto service experience. How are you doing Bernie? 

Bernie: Doing very well. 

Mark: So we're going to talk about a 2001 Chevy Silverado diesel that had a problem. What was going on with this truck? 

Bernie: Yeah, so this truck came to our shop with the crankcase filling up with too much oil. The oil level is actually going too high and it was starting to leak out. The customer had some issues with this for a while, had it at another shop. They'd done some work on it and weren't able to fix it. So they brought it to us. 

Mark: So, what did you discover was causing the engine oil level to rise? 

Bernie: Yeah, so what is in fact happening, of course the engine oil level will only rise if you pour more oil in which wasn't happening. But what happens on a diesel like this, and a lot of diesels, they have internal plumbing, the fuel injectors are inside the engine. The injection pump has a seal into the engine and there's a whole array of plumbing under the valve covers into the engine which can cause diesel fuel to leak and fill a crankcase up with diesel fuel. So the oil level is going up, but it's actually really diesel fuel that's filling up the crankcase. 

Mark: And diesel fuel does not do the same job as oil in your car. 

Bernie: It isn't, I mean, it, it is a lubricant but not as good as oil and it's certainly not formulated to work like motor oil. So it's not a good thing. 

Mark: Yeah. So how can that, so this was filling up quite a bit, what was going on? Why was it filling up with so much diesel? 

Bernie: Well, as I mentioned, there's a few ways it can leak. A few ways diesel can get in. One is through the, there's a seal in the injection pump where the injection pump bolts to the engine. There are fuel injectors, of course, that can leak. And then there's a lot of plumbing under the valve covers from each injector through their return lines. And on this particular engine, those have a number of seals and pipes and things that could leak fuel as well and fill up the crankcase.

So it's really a matter of doing some testing but just take it a step further. The owner had previously had all the injectors replaced at another shop. They had done the work. I believe the problem was there beforehand. They took everything apart. Apparently according to the owner, three times to try to find the leak, they said, there's nothing wrong with the work that they did. Everything was fine. 

And so he brought it to us to take it to the next step. And from there, we really concluded that, you know, assuming that the other shop had done a good job you know, that there was only one other spot that he could leak from. And that was from this fuel injection, the high pressure injection pump seal.

Mark: So you changed the pump. What sort of work is involved in replacing a diesel injection pump? 

Bernie: Well, it was a fair bit of work involved in doing one of these? I think we should just get into some pictures. We can have a look at it, but yes, we changed the injection pump.

So there's our 01 Silverado you know, it's a bit of an older truck, but still a lot of life left in it. Injection pump. There is the old injection pump. Just a couple of pictures with the injection pump removed, this is the seal that sort of seals the engine oil out from getting into the injection pump. Inside the injection pump, there's a higher pressure seal. You can actually see a little drip of fuel here. When we pulled the seal off, I thought, hey great, you know, we actually did find the leak because there's diesel fuel behind here. And of course there shouldn't be. So that's basically the front seal of the injection pump.

There is sort of where the pump is located. So this is the top of the engine. You can see the turbocharger back here. A lot of the air intakes have been removed. The pumps buried in back here behind some of the coolant pipes. It's a fiddly job. It's not as hard as doing the injectors, but there's a quite a number of hours of labor involved in taking the pump out and replacing it.

This is a view of the new pump with the new seal on the front. And one last picture to look at, this is the oil we drained out of the engine. So that's a 20 litre pail. You can see there's probably about 16, 18, 17 litres of fluid in there. There should only be 10 that's how much the crankcase. So the levels should be down around here somewhere, where to drain it. So got probably at least seven extra litres of diesel fuel in the crankcase, which is what we pulled out. 

Mark: So basically a pretty big problem that took a lot of effort  to repair, how often do you see this issue with Duramax diesels? 

Bernie: We haven't run into it too often in our shop. It does happen from time to time and it can happen on most diesels you know, because I said that there's a lot of internal plumbing. A lot of diesels, and isn't just, you know, American truck diesels, but a lot of other diesels they'll actually have a warning that comes on if the oil level gets too full. I know we've seen it on a few others. So there's a monitor for that, because of course, you don't want too much fuel in the crankcase. It'll dilute your lubrication, which is not a good thing. Plus the oil actually starts leaking out. You know, so when it gets really bad, you'll know it, but it's not a good thing. 

Mark: And how are these Silverados for reliability? 

Bernie: Oh, super good. They're kind of still my number one for North American diesel. Just especially if you take an 01, they're definitely, I'd say the most reliable, but you know, a small margin. And now these, of course, this truck is getting pretty old. It's a 20 years old now. So more problems are starting to occur. But you know, when these things were younger, say 10 years old, if you compare it to a Ford, there's a lot more, I know Ford owners hated me saying it, but truth is true. You know, there was just more problems with Fords. And Dodges have been pretty reliable, but you know, there's, there's a few issues. It just seems like the GMs have been more reliable overall.

Best auto repair in Vancouver, British Columbia, Canada. That's an impressive accomplishment. We're going to talk about a 2013 Mercedes-Benz ML350 that had a bit of a wiggly rear end. What was going on with this SUV? 

Bernie: Well, it actually came to us, well I guess it may have had a wiggly rear-ended and to be honest I never drove the vehicle, but it did come in with a couple of fluid leaks and one of them was coming from the rear shock absorbers.

Mark: Okay, so why would the rear, what type of suspension is that, that the shocks would leak. 

Bernie: Well, shock absorber has fluid inside. So all shock absorbers can leak fluid. Now, some Mercedes use a hydraulic suspension system where you could have potentially a humongous leak, but these do not use that. These Mercedes MLs, they use an air suspension system. So that adjust the height of the vehicle. Basically the springs are air and not metallic would be the easiest way to say it. So you can adjust the height of the vehicle. But the shock absorbers they're a special electronic shock absorber. So they have, you know, more fluid than usual, but basically that's what was happening. The fluid was leaking. 

The shock absorption actually occurs from fluid, which dampens the balance of the spring. And it goes through a certain valves and that's how the shock absorber works. It is filled with fluid and eventually seals will leak and the shocks will leak. Same with struts as well. If they're, you know, a fluid filled strike, which most are. 

Mark: Yeah, I guess it's like if you've ever seen, as more common for us older guys, but a vehicle gets going down the road and kind of bouncing along, trampolining along over every bump, it kind of goes the shock absorber just makes that happen and stop. Is that right? 

Bernie: It does. Yeah. It allows the spring to do one up movement and bounce down instead of oscillating because springs will just keep oscillating. And if you've ever been in a car that has blown shocks, it's a horrible feeling to drive it. I can't imagine what it must've been like in the olden days before they had shocks, you know, or in a horse drawn carriage. It's that continuous balancing it'd be, I mean, it's better to have springs than no springs, but the bouncing feeling it's just sickening when a vehicle doesn't do that sort of one bounce and stop kind of thing. So shocks are amazingly important. 

Mark: So what is an electronic shock absorber do that's different than a regular shock?

Bernie: Electronic shock absorber allows a different ride conditions. So you can have a sport ride. You can have a comfort ride. So the comfort ride allow the shock to be a little bouncier, whereas on sport ride will be much firmer. So when you hit a bump or you go hard around a corner, the car doesn't move so much. So that's kind of the difference. There's some trucks that have adjustable shocks where again, you can firm up the ride if you're going off road. You don't want the vehicle to bounce too much off road, so you can adjust that as well.

So adjustable shocks. They work at a couple of different ways and some of them they'll just have a valve, it'll change size and allow the fluid to flow at a different rate. But electronic shocks are interesting. These type, because a lot of them, and I'm not sure on Mercedes, whether they have them, some of them have a magnetic type of fluid and by changing, by sending electrical pulse into the shock, it'll change the alignment of basically the fluid. And so it'll flow slower through a valve. It's kind of interesting. So interesting technology. 

It seems to me, this is my experience, it seems to me like those kinds of fluid shocks tend to leak more easily than others. And it's probably because, again, I'm just guessing not an expert, but just guessing, that it's probably due to the fluid may be a little grittier and harder on the seals. That's my guess. 

Mark: How does this part of the suspension system fail and leak?

Bernie: Basically as I mentioned, I mean the leakage, you know, it just happens over time.

Here's a view of the shock absorber, this is the right rear shock. I mean, you can see a stream of fluid coming down there. This is like kind of a dust cover bellows here. But inside up above there, there's a seal that seals the fluid out and so that leaks. This is the electronic chamber in the shock absorber. Again, I'm not certain if this actually has that magnetic type of fluid or whether this electronic part here just changes the valving inside the shock absorber. I don't know for certain, but in nonetheless it leaks.

 Here's the left rear. I mean, both were leaking a lot of times we find these vehicles where only one shock leaks, but in this case it was a double whammy, both were leaking. And when we put the vehicle up in the air,  after a few minutes, there's quite a drip on the ground. So they've been leaking for a little while. There's are 2013 ML350 parked in front of our shop.

Mark: So since they're fancy electronic shocks, are they expensive to repair? 

Bernie: Yeah, they are. Yeah. They're not cheap. It's an expensive job. Any suspension beyond just regular shock absorbers, you know, it can get pretty expensive and pricey to fix. So I'd say they're cheaper than the repairs in a hydraulic suspension in an SL500, but they're certainly    pretty pricey. 

Mark: And how common is this as a failure point? This is a 2013, so it's had a pretty good run. 

Bernie: Yeah, it's actually quite common. We've done them on quite a few of these cars. So I think if you, if you keep this vehicle for, you know, it was 2013, that's what seven, eight years, eight years, eight years old. I mean, if you know that they seem to fail, you know, a lot of them by 10 years old. So unfortunately hate to break the news to you if you own one of these, but you'll probably have to repair them at some point. It's just kind of part of the game. 

Mark: And how are, especially in these generations, how are they for reliability?

Bernie: They're pretty good. This is a diesel, you know, we've talked a lot about the diesel issues. Yeah.  Yes. Yeah, no, I mean, they're good. I mean, there's a lot of things that do happen with the diesels. And you'll find all sorts of information on other podcasts, but you know, the suspensions do have issues on these vehicles.

We do a lot of repairs on the air suspension, the compressors and often the valve block that diverts the air to the different air struts will fail. So that's the common issue on those. I mean, eventually the air struts themselves will fail. We don't see too many of those yet, but you know, it's a good vehicle, but stuff goes wrong and happens and that's par for the course. So just be prepared.

2005 Jeep Grand Cherokee, Front Differential Mount Replacement

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 24 time winners of best auto repair in Vancouver as voted by their customers. And we're going to talk about a Jeep Grand Cherokee today. How are you doing Bernie? 

Bernie: Doing very well today.

Mark: So 2005 Jeep Grand Cherokee had a problem with the front end. What was going on with this vehicle? 

Bernie: The owner of the vehicle actually brought it into us for A maintenance service or oil change and basic inspection. Along with some oil leak diagnostics, we actually done some previous oil leak diagnosis on the vehicle. There was still some leakage. So he wanted to figure out what was going on with that and fix that. So that's why he came in. However, when Nigel, our technician who was working on the vehicle, drove it and he heard this very loud thunking noise in the front end of the vehicle, like extremely loud. So he figured there's something worth looking at there, some serious going on. 

Mark: So you guys dug in, what was causing the noise? 

Bernie: Yeah. So Nigel had a look underneath and kind of wiggled a few things around found that the  mount on the rear end of the differential was completely worn out, causing a huge amount of play. And I'll show a video in a few minutes which illustrates perfectly what was happening. 

Mark: So what would cause that mount to wear? Aren't they supposed to stay in place for a really long time? 

Bernie: Well, they are, but it is a rubber mount it's allowed to have a bit of movement. So, you know, over time, movement amplifies and eventually the mount tears and maybe they could have made it tougher. But there's always, I think the manufacturers, they always try to balance the comfort ride of the vehicle versus durability. And so sometimes I'll put a softer rubber bushing on a control arm, which wears out faster, but there's a more comfortable ride to the vehicle. So it's kind of a balance and compromise, but I'd say just wear and tear, old age is kind of what's caused it. It's a 2005 Jeep that makes it 17 years old. So it's had a bit of usage. 

Mark: So what's involved in repairing the mount, the broken mount? 

Bernie: Removing the differential. So the axle shafts have to be removed from the differential. The drive shaft from the transfer case needs to be unbolted. And then there's basically three mounting points that need to be removed. And then the differential just drops down. So let's just look at some pictures right now. So this is a little video that shows the wear on the differential. I'll play it a couple of times. 

So I didn't do an after video, but basically that should not be movable. That's actually with a hand grabbing the differential and just pushing it up and down. So clearly a lot of wear and definitely the cause of the loud thunk.

This is the differential out. This is the mount. There's supposed to be a piece in the middle here. You'll see it in the next picture, but that's basically what was left of the mount. You can see to the untrained eye, it does look pretty bad, I'd say. This is the whole differential assembly here.

There's the new mount. There's what's left of the old mount. It's it's a little dark in this picture, but there's sort of an airspace here. You know, the mount is solidly attached in this spot. So what 50% of it is solidly attached to the rest allows some movement of the mount.

And I guess, you know, from an engineering perspective, they want a little bit of cushioning. It's a more comfortable drive, less harshness. But of course, if it was, you know, solidly mounted, it would never wear out. But it would create a lot more of a rough feel to the vehicle.

There's the differential. There are three mounts and we did actually replace all of them. So there's the front one that was completely worn out, brand new. The rear mount, sorry, hang on I'm trying to think, no, this is the upper mount. This is the one that was worn out.

So you can see the sort of solid pieces here and the air gaps here. This is the right side of the mount, and then there's a front mount here, which is a bolt on piece.  One more picture. There's the differential before we replaced it, mounted in the vehicle.

So you can see the front mount is bolted in here. Then the other mount would have been up in this corner here and then the worn out mount buried away up in the frame of the vehicle. So there's our show for the day. 

Mark: So how common of an issue is this on Jeeps?

Bernie: You know, we work on a lot of these and this is actually the first time I think we've replaced these mounts, but the parts are readily available. So I'd say it's a fairly common wear out item, but surprisingly it's the first time we've replaced them. 

Mark: I guess it depends on how they're used too, if something's been off-road an awful lot and getting pounded a lot, up and down, over rocks, et cetera. It's going to have a little bit faster wear than something that's just been driven on the highway. 

Bernie: Absolutely. And most of these vehicles, you know, most people who drive these vehicles most SUV's, they never even get off road or maybe the odd little, you know, light gravel road, but yeah, for people who get out and use them a lot, this is going to wear these a lot faster. And you know, not that it's a bad thing. I mean, it's just a normal part of wear and tear with this design a vehicle. But yeah, certainly if you're just driving on the highway and using it gently, you know, these will not wear that fast. 

Mark: Was there anything else to replace other than the three mounts that you changed?

Bernie: That was all we did. That's all it needed to be done on this particular job. We did change the differential fluid while we had it out as well. Some of it did drain out as we took the axles out and it was a good time to do a full fluid change. So we did do that.

Mark: Anything that a Jeep owner can do to prevent this kind of wear and tear to prevent these mounts from wearing out? 

Bernie: Well, I think we just talked briefly about usage. And I think, you know, if you're going to accelerate full throttle every time at a light, you're going to wear stuff out, probably your engine mounts worse than the diff mounts.

But I think the key is just to, you know, drive it with a bit of gentleness. If you're off road, you know, don't go flying down the road and flying over bumps, you know, just go a little gentler. But other than that, I mean, things will wear as they wear. There's not much you can do with these are just a solid piece and they'll just do what they do.

Mark: And were there any other repairs on this Jeep at this service? 

Bernie: Yeah, actually the engine oil pan was leaking. So we replaced the gasket and actually having the differential out, made that a little bit of an easier job because the differential's in the way of the oil pan. Also the radiator was leaking as well. So we replaced that too, but those two jobs are completely different story. We've probably done a podcast on Jeep radiator leaks. They're kind of complicated to replace in these vehicles. So I think we did one at some point in the past. Maybe it's time to do another one some time soon, but yeah, that was it. And an A service, a basic oil change, A service. 

Mark: How are Jeep Grand Cherokees for reliability? 

Bernie: Well, they're kind of up and down. I'd say they're not quite as reliable as a Toyota Four Runner would be, but you know, you pay a lot less for them. I think they're pretty good. You can go places with them. A few more things go wrong. I think this 05 model year is pretty good engine wise, you know, we're starting to see some issues with camshaft and lifter wears in the V8s of the sort of 2010 and up models. These don't seem to have that kind of issue.

You know, the diesels are, you know, they're a category of their own. What these to the mid 2000 Cherokees, and there's a lot that goes on with those. They are kind of like the, they're a Mercedes diesel. So they have the issues. But there's a few things that were out on them and some of them get used pretty well, but you know, I think they're pretty good vehicle. If you're looking for a good off-road vehicle, I think they're really good.

2011 BMW 328i, Rough Running Engine

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. We're talking cars. How are you doing Bernie? 

Bernie: Doing very well. 

Mark: So today's story. 2011 BMW 328i. What was the story on this BMW? 

Bernie: So it came to us and the engine was running rough. The check engine light was on and needed some repairs.

Mark: What diagnosis and testing did you proceed with?

Bernie: So from there, first step of course, is to hook our scan tool up.  See what stored trouble codes are in the system. Found a couple of lean condition codes and it was very evident the engine was quite rough. So next step, of course, pop the hood, do a visual inspection. See if we could see anything obvious that was causing it. Nothing was noticeable. So our next step, one of our piece of diagnostic equipment is a smoke machine. And what it does is, under very low pressure, I think about a half PSI, it'll generate half PSI pressure and it generates smoke. And also the smoke has a bit of a UV dye in it, which is kind of cool. You can use for tracing as well. But essentially we, we hooked that into the intake system and turn it on and it pumps smoke through the intake system. So if there's any vacuum leaks or any leaks of any sort, we can find them.

And lo and behold, we found a huge leak coming from where the PCV pipes connect into the intake manifold. Kind of buried low down in the engine. A little hard to see, but we were able to you know, get some flashlights in there and see it, and found the PCV connector was damaged and causing an enormous vacuum leak.

Mark: Okay. So that was a big jump. Like why wouldn't you have looked at other things that might cause rough running first? What led you to the smoke machine, that there might be a vacuum problem? Is that common with rough running? Like what led you there first? 

Bernie: It is especially with the code, this is where the trouble codes are useful. Now people think, oh yeah, just plug the computer and it'll tell me what's wrong with it. Well, no, it doesn't. It just says that there's a code that, that the vehicle can't adjust the fuel mixture. Essentially the interpretation is the engine's too lean. There's too much air getting in. For the amount of fuel that the injection system can deliver. So there's the problem. 

So this is where we have to use our brains and our experience and our other equipment to figure out what exactly it is. The computer does not tell you that it's this particular piece that would make our was a lot easier if it did.

But you know, just as a little aside story, I often thought it'd be great if they put a fuel injection pressure sensor because often fuel pumps will fail on vehicles. I thought, wouldn't it be great if they had that sensor that would tell you that the fuel pump had failed? Well, some vehicles actually have that because they actually regulate the fuel pressure in the vehicle.

Well, that's actually one of the common failure items on those particular, not a BMW, but other vehicles, the sensors actually fail on these vehicles and they cause more problems than the vehicles that don't have them. So I thought, well, it's interesting, you know how sometimes you can over monitor stuff.

Anyways, I kind of went off a bit there, but anyways, the smoke machine, once we determined it's it's a vacuum leak is probably too much air. Smoke machine's a great tool because we can verify right there is it because of too much air because there could be other things like maybe the mass air flow sensor is reading incorrectly, but if we can verify and visually see that there's no smoke coming out from anywhere, then we know there's no vacuum leak. So that's why the smoke machine is a great tool. 

Mark: And how often do you end up using a smoke machine for testing? 

Bernie: We use it quite often. I mean, I'd say like about out of a hundred diagnostics, maybe 20% of the time we'll use it. You know, if it's something with with a vacuum type of leak, we'll use it. It's also useful for exhaust systems. If we can't quite determine a leak or there's maybe a pinhole of some sort, we can pump the smoke through there. There's a number of things this thing's useful for. Especially EVAP system leaks. It can be like a very tiny little leak coming from somewhere. So very good for finding little minute leaks.

Mark: So what was involved in repairing this PCV hose connector? 

Bernie: So we have to remove the intake manifold and in our intention wasn't to take it entirely out of the vehicle because it was actually, if we could swing it out of the way we could take the screws off and unbolt it, that was our original intention.

However, the job ended up turning out to be a little more involved and I'll get into some pictures and we'll have a look.

So that is the intake manifold of the BMW off the car. So eventually we have to take it off because if you can see, this is where our PCV connector was, was, and you can see a lot of kind of roughness there. This manifold is made of plastic and it was melted here. Now, normally there's no heat around this area that would cause it to melt. But this particular part here has a heater in it for the PCV system and electric heater. And it basically it must've short-circuited and melted.

This is our melted PCV heater. You can see very large hole here. That's where our vacuum leak was. This part, is what bolts into the intake manifold, as you can see, it's very deformed and why it would have melted the manifold. And the PCV hose connects here as well as here. It's like a double PCV hose. So it sucks and this part and this heated section as well. So that hose was replaced also. 

This is what the new heater unit looks like. You can also see there's an electrical connector there. Everything is is in pretty good order on this piece. It gives you a better idea of what the piece looks like. 

And a close-up of our melted area. You know, we ordered the heater first because we figured that's what we needed. But as we looked further and struggled to get this thing out, we realized the manifold would definitely not have sealed with that a new piece in there. We would've had another vacuum leak. So the manifold had to be replaced as well.

Mark: Okay. Did you have to get a brand new manifold? 

Bernie: Oh, we're able to get a used one from an auto wrecker. I mean, this is a part that really doesn't fail, it's a good used part to buy. There's nothing mechanical inside. It's just a piece of molded plastic. And as long as this thing wasn't burnt or there wasn't anything cracked or broken because of course, in a wrecker, in an accident if a car got hit hard enough and you know, a plastic manifold, you get cracked, I've seen that happen, but as long as it's good and solid, it's as good as brand new, essentially.

Mark: What else did you have to replace or repair along with the manifold and the PCV? 

Bernie: Yeah. So we did the PCV pipe. I didn't show a picture of that, but basically it's a pipe that connects to the two sections in the manifold, loops around and connects up to the back of the engine to the rest of the crankcase breather system.

Also the electrical connector to the PCV heater is completely melted and disintegrated. So we have to acquire that. And the only place we could find that was from an auto wrecker. It wasn't available new from BMW. Sometimes they sell these things. You can buy the connector and then the little wiring bits inside and you put them together, but electrical connectors are a little dicey. A lot of them are highly specialized and only fit in one spot. And they're only built one way. So we managed to get a good use one from the auto wrecker and soldered, you know, put that in real nice. 

Mark: So remind us again, what does the PCV valve do. And then why would it need a heater?

Bernie: Good question on both. Okay. So first of all, the PCV, actually PCV stands for positive crankcase ventilation. So the V is not actually double because sometimes it is.  It's a positive crankcase ventilation valve. What it does is it basically takes the blow-by gases from the crankcase, when it internal combustion engine is running some of the explosion that happens in the pistols, it can't be contained fully by the piston rings. It'll blow past into the crankcase. And so those gases, which are highly noxious are the most horrific pollutants, the engine puts out.

 They basically capture it, instead of it going out into the environment it's captured in a closed system, goes through a pipe, goes back into the intake manifold, it's sucked in and re-burnt. Why they use a heater, I don't know. But some vehicles do have them. It may be just to prevent the oil vapours from condensing in a cold engine. That's what I'm kind of assuming is what it is. And I should do my homework before I do this podcast, but I didn't.  

Sometimes I don't dig as deep as maybe I should, but I go, it's there for a reason. I figured no car manufacturer ever puts anything on a car for no reason, because it all costs money to make. So they're all committed to doing it the cheapest way they can. So there's gotta be a reason, but I'd say it probably prevents the vapours from condensing as they get sucked into the intake manifold on a cold engine. 

Mark: And how did the car run after repair?

Bernie: Really good. Yeah. Ran fantastic. Like a brand new BMW, smooth and no check engine light. And it was nice to find this issue because you know, so often we do diagnostics on things where we can't see what it is. We have to kind of interpret things and go, okay, well I think that's what it is and give an estimate for a thousand dollars. And it works in the end, but it's like, it's always a little hairy. But this is nice when you can go, Hey, the smoke machine, there's the leak right there. There's the problem, you know, it's a hundred percent found and verified. So it was a nice repair story. 

Mark: And is this a common issue with BMW 328 series vehicles?

Bernie: Not that I know of know, we work in a lot of BMW. This is the first time we've ever seen this happen. It's common in a lot of other different BMWs. You know, the auto wrecker, when I brought the sample manifold out, the guy who pulled it out of the car, he goes, wow, this is weird. I've never seen this before. So to me, that's an interesting indication that it's not an entirely common occurrence, but it may happen from time to time.

Mark:  And how are these BMWs? The 300-320series, I guess, how are they for reliability? 

Bernie: Well, you know, they're okay. We do a lot of podcasts on them. You know, I just like to say, you know, if you own one of these cars, they're nice, but you'll do a lot of repairs over time. I think, as we said, this isn't the most common thing you'll come up with. But electric water pump failures are common. Oil leaks are common. So, you know they need good maintenance. That's kind of the key. A lot of people don't maintain them well. The factory maintenance schedule on BMWs in my opinion is really bad, that your oil change intervals are like 25,000 kilometres, which is way too long. You should be doing it at 12 or maybe even less.

You know, if you do it more frequently with good oil you're going to get a lot more life out of your engine for sure. If you're buying a used one and it's been dealer serviced, it may not be the best service that could have been done. I mean, at least it's been done, but it has been done more frequently, that'd be better.  

Mark: So there, if you've got a BMW in Vancouver and you want to maintain it, you want it running a little bit more trouble-free. You want it maintained so that you can go in and start it up. And it goes even in the cold winter and the rain. The guys to see are Pawlik Automotive. You can reach them to book your appointment 604-327-7112. Or you can book online pawlikautomotive.com.

2006 Volvo S60R, All Wheel Drive System Repairs

Mark: Hi it's Mark from Top Local, I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 24 time winners, 24 times best auto repair in Vancouver as voted by their customers. We're talking about a Volvo today. How are you doing Bernie? 

Bernie: I'm doing very well. 

Mark: So all wheel drive system on a Volvo, what was going on with this vehicle?

Bernie: Yeah. So this vehicle had a warning light on the dash that the all wheel drive system wasn't functioning. That's basically the issue. The owner also noted that when there was some slippery surfaces it didn't feel like the four wheel drive system was actually working.

Mark: So what testing and diagnosis did you do? 

Bernie: So first thing, hookup a scan tool to the vehicle computers. Did a full system scan. There was two codes in the all wheel drive module or rear differential. I can't remember which term they use on this particular vehicle, but there's two codes, one for a communication issue with the differential module and one for a pump, issue with the pump. So we did some testing on the system as much as we could. Under the vehicle, found that the pump was definitely bad. And that was our first item to replace. 

You know, as far as communication errors, sometimes if there's a component that's part of the system, it will create a communication error on certain vehicles. Other times the communication error could actually be that the module had failed or something else. So we figured that the pump was a first place to start because we knew that was a problem. 

Mark: So you replaced the pump. Did you have to do anything else after that? 

Bernie: So, what we did is we replaced the pump along with the pump, we also replaced the filter and service the fluid. I mean, some of the fluid had to come out anyways, but it's a good idea to service the fluid once in a while in these systems because it's kind of a critical part of the system to use the right fluid. So we serviced the fluid, the pump, the filter tested it all out and there were still issues. 

Mark: So what was the next step? 

Bernie: Yeah, next step, so we rescan it. There's still a communication error code. So just did a little further testing on the wiring to the module to make sure there was proper power, ground, communication, circuits, that sort of thing. It was all good. So at that point there's really only two things left. I mean, the most likely the module, possible issue with the actual clutch packs, but not very likely considering the code is a communication code. So we proceeded to have the module repaired and replaced. 

Mark: So what's involved in replacing the module? 

Bernie: Well, labour wise it's pretty simple. It bolts onto the side of the engine, not the side of the engine, sorry, the side of the differential. And I'll get some pictures up in a second, but there's really a couple of options available for replacement. There's brand new from the Volvo dealer. There's used modules if one can find them and also having them rebuilt. We have a company that rebuilds a lot of electronic components. And they actually do a really good job in these things. They do a lot of them, so I'll just get some pictures here. So we went with the rebuilt option.

So there's our Volvo. This is a S60R model, which is kind of cool. It's like the high-performance edition and it it goes well, drives real nice. All wheel drive. Nice high-performance Volvo.

There's the module. This is the rebuilt unit. The nice thing about these rebuilts is they come programmed. You know, this an issue if you buy a used one, it may need to be reprogrammed to the vehicle. Modern vehicles they all have to be, modules need to be programmed so the computers connect with each other. I don't know why such complexity, but for some reason they do it. And it just makes repairs more fiddly inexpensive. But these come reprogrammed, which is a good thing. If you're buying a new one from Volvo or a used unit, you'd probably have to do the same thing.

Anyways, here's a view of the the differential unit. This is the Haldex unit here. And this is the module here, kind of looking at the other side of it, from what that picture was. Pump's located here. This is the drive shaft that comes from the front of the vehicle, hooks up with this coupler here. And then inside this area, there's all the clutch packs that kind of do the all wheel drive operations. So there's our picture show for the day. But yeah, the module basically is quite simple. It just bolts onto the side with some electrical connectors. 

Mark: And how did everything work once the module was replaced? 

Bernie: Perfect. No warning lights were all out. No more codes. All wheel drive system worked great.

Mark: So, is there anything unique about this Haldex all wheel drive system? 

Bernie: They actually use it on a number of different European vehicles. This system is used on Land Rover LR2s as well. There's some Volkswagens that have Haldex's. But this type I mean, what's unique about it. It uses electronics to control the slippage between the front and rear axles, which is important for, you know, good driving comfort, and then also good you know, differential lock up when you need it in slippery conditions. 

Mark: So is this a typical failure in these units at some point in their life?

Bernie: You know, some do. I mean the modules do fail. We've replaced all sorts of bits and pieces on these, like modules pumps, they all tend to have problems. But you know, there are many Volvo models that don't have problems at all. So it's not sort of a guaranteed failure if you own one of these, but you may run into one or two of these items. And sometimes, you know, the pump will be bad and it'll actually take the module out. So you know, it's often better, even though we did this in a couple of sequences, that if the module is bad, it's often a good idea to replace the pump at the same time, because it can cause a module to go. And it would be a shame to put a module in and have it blow out because the pump was not replaced. It's drawing too much current or something like that. 

Mark: And it works really well as far as the four wheel drive system. 

Bernie: Yeah, it does. For sure. I mean, you can't really tell you have it. If everything's working well you can't really tell it's a four wheel drive. If you've driven any, I always think of like American trucks or like a Jeep where you put it in four low and everything's locked in, you go around the corner on pavement and the wheel start hopping and grinding and binding. So, you know, you don't get any of that kind of thing on this sort of vehicle. So you can be driving in four wheel drive all the time, but it controls things. So it's comfortable to drive.

2002 Porsche 911 IMS Bearing Repair

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. What is it? 24 time winners. 24. Best auto repair in Vancouver as voted by their customers. And today we're talking about a Porsche 911. How're you doing Bernie in? 

Bernie: Doing pretty good. 

Mark: So this had the infamous IMS bearing problem. What was going on with this vehicle? 

Bernie: So the vehicle got towed to our shop with a sudden, humongous oil leak developed in the vehicle. We didn't know it was an IMS problem, but we did know there was a huge oil leak that had developed. 

Mark: Was there any diagnosis you had to do to find the oil leak?

Bernie: Well this wasn't our traditional, there's always a diagnosis of some form, but it wasn't the usual, let's add some UV dye. Clean something, drive it around the block. It was basically as fast as we could pour the oil in, it was pouring out. So there was a pretty severe leak coming from somewhere.

Mark: Either that out of the engine drain is not in there anymore. 

Bernie: Well, yeah, that wasn't the case though. So the oil is pouring out in the bell housing area. So either, you know something happened to the IMS bearing, the rear main crank seal had blown out or something catastrophic had cracked at the back of the engine. So we figured pulling the engine out was the next step to the process. So we pulled the engine and transmission together as a unit and separated it and. Proceeded from there. 

Mark: What did you find? 

Bernie: So we found the IMS bearing had basically broken. There's a bolt that holds the IMS bearing to the collar. It was missing. Gone, and those oil just pouring out of there. So next step of course, is pull the IMS, played out and see if we can replace the IMS bearing. 

Mark: So that bearing had failed. Did you replace it? 

Bernie: We weren't able to because the bearing had basically grenaded. Just destroyed itself. And this vehicle requires a complete engine. So why are we doing this podcast? Because we're talking about why you should replace your IMS bearing way before there's any issues. That's kind of the purpose. So we can get into some pictures. We can talk some more while we're looking at pictures.

So there's basically what we found. We took the engine and transmission apart with the flywheel off, you can see the rear main crank seal in this area and the red arrow points to the IMS plate. There's a hole in the middle and you can see a sort of a, kind of fresh oil that's run down here. And that is basically where there used to be a bolt and a shaft that sat in there. And that had basically broken off. Very bad thing for that to occur. Next pictures. What do we got?

Again, a close up view of the IMS cover plate. There shouldn't be all that metal laying around in there. Metal in, well, just, just looks like it's been sandblasted and there's still sand in there around this area here. No underneath like where the oil is and just right where your arrow is now.

I mean, that could be dirt. That's accumulated kind of hard to say. I think most of the guck would be inside the engine at this point. Now here's what it looks like with that piece off. I apologize. It's a bit of a fuzzy photo, but that right in this opening here is where the IMS bearing used to be.

And that's sort of, what's left of the outer bearing race that sits in the IMS bearing. At this point, you can't replace it. It's it's too badly damaged. And of course all the debris of that bearing is now circulating throughout the engine. 

Mark: Thus you need a new engine. 

Bernie: Yeah. Thus we need a new engine or, you know, tear it apart and dismantle it, but it's an enormous task. We're in the process actually right now, trying to find a good used engine for the customer. That's kind of where we're at. I mean, it's either that or you rebuild it, which is a horrendously expensive operation. 

 There's the plate. This is where the bearing once sat. You can see, you know, a lot of wear and crap around this area too. And then finally, this is what a replacement, LN Engineering bearing looks like. This is an aftermarket solution that works really well in these vehicles, but it's only a preventative maintenance repair.

This is not a after the fact of severe damage repair. This is a repair that you do when the IMS bearing has not yet failed. So that's a solution, a part. It also comes with a different style mounting plate because it's a different design. But yeah, so there's our, there's our picture show.

Mark:  So, what does IMS bearing do? 

Bernie: So what it does is it basically holds the intermediate shaft in place. And what the intermediate shaft is, the purpose is basically it's an overhead cam engine. There's timing chains that run from the well, no, on a lot of engines, they run directly from the crankshaft to the cam shafts.

But in this case the engineers at Porsche decided let's run an intermediate shaft, which slows the speed of the timing chains down to the cam shaft, cuts them in half. So it seems like a pretty neat idea. Unfortunately in the design of this bearing, this bearing is not lubricated by engine oil. It's a sealed bearing. So it only has a limited lifespan. Of course they don't tell you that. It's not part of the maintenance because they never designed it that way. They didn't think about that that far. 

There was actually a class action lawsuit that occurred a long time ago about these bearings. And I don't know much more about it, but it's out there. So they had these things fail under warranty as well, but now anyone who owns one of course is left holding the bag and you need to replace it yourself. But that's basically what the IMS shaft, you know, what the purpose is.

Mark: So does it matter whether it's air cooled or water cooled, because there was a change somewhere in there with Porsche? 

Bernie: Air cooled engines have, they have a lubricated bearing, like as kind of standard, I guess you know, a standard type of bearing that's lubricated with engine oil. So there's no problem with that. And when we get into the newer models, probably 07 and newer, they solved this issue. They either eliminated it or did something that this bearing is not a sealed bearing unit anymore. So really your problem years are probably from around approximately 97 to around 2005 or six with apparently the years, 2000 to 2005 being the worst issues.

So and that's 911s and Boxsters because they both use the same design.

Mark:  So was there any warning signs for this 911 owner? 

Bernie: No there wasn't and we just did a service I think, a month or two previous to this, changed the oil, there was no, you know, we generally look at the oil. There was no debris or particles or anything to be found in the oil. I mean, we didn't cut the oil filter apart, perhaps we should have. Maybe we would have seen something, but many times these bearings will fail internally. You know, the bearing will start wearing out and collapsing and then they'll just suddenly give out all in one kind of puff, I guess. Exactly. Yeah. They just kind of explode. So that kind of thing happens. 

So you can get magnetic drain plugs, oil, drain plugs, which are a good thing to see if there's any metal debris forming. Really a lot of times there's just no warning. We did have a Boxster once where there was a screeching noise in the engine and we did actually, a bearing was in pretty bad shape. We did actually replace it. The engine seemed to survive, but it wasn't like this where it completely blew apart. 

Mark: So what's the way to prevent it from happening from having the grenade explode? 

Bernie: You basically need to replace this bearing. I mean, it's that simple. If you don't know when it's been done, get it done. This LN Engineering, they have a couple of different options. They also have a solution where you can actually get a bearing this lubricated with engine oil, which is a more expensive option. I don't know if it's necessarily worth doing, but I'd say it was my own car, I'd figure, you know what I do it. And then if I was going to keep it long enough, I'd say within 10 years, I'd replace it again. That's kind of the way to go. It's a maintenance item and you just got to treat it like that. So if you don't know when it's been done and you can't find any hard evidence that has been done, I would just go ahead and do it. It's expensive, but way cheaper, a fraction of the cost of replacing an engine. 

Mark: So little hidden surprises for the 911 and Boxster owners of a certain vintage. How are 911s overall for reliability? 

Bernie: Super reliable vehicles. I mean, this is the only thing really that in my opinion, it's really bad about these vehicles. Other than that they're excellent .For a sports car, they run well. They just need some basic service. It's a great car, really overall not that expensive to maintain for what the kind of car it is.

2008 Land Rover LR2, Hard Starting

Listen to podcast here.

Mark: Hi, it’s Mark from TLR. I’m here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver’s best auto service experience. 24 time winners of best auto repair in Vancouver. And we’re talking cars. How are you doing Bernie?
Bernie: Doing very well.
Mark: So today’s victim, we’ve seen a few of these, a Land Rover LR2 2008 version. What was going on with this vehicle?
Bernie: So the owner brought the vehicle to us. He bought it recently, done a few repairs himself. And the issue that he was having as the check engine light kept coming on and the vehicle is hard to start. It would crank over for a long time before the engine would eventually start.
So he’d done a bit of research, he’d replaced a few parts, fuel injectors, fuel rail pressure sensor, a lot of the things that could commonly cause an issue like that he’d replaced. Issue was still there. He said, Hey, you know, can you guys reprogram the vehicle powertrain control module. I said, yeah, it seems like a good idea. We can do that. So we did that.
Mark: And what was the result?
Bernie: Well, it didn’t solve his issue. So he still had the same concerns. About two weeks later, he booked in and brought it back and we said, Hey, we’re going to need the vehicle for a little while, based on what you’ve done.
There’s obviously some interesting issues. You know, something that might take some time to figure out. Leave it with us for a bit and we’ll look at it. So he brought it back and we started doing some tests and diagnosis on it.
Mark: So, what were the diagnostic steps that you took?
Bernie: The first thing was to test the fuel pressure. Do a complete vehicle scan and look at the data on the scan tool. So, first thing we noticed is the fuel rail pressure was a little out of spec. We suspected, you know, the pressure sensor that he put in may or may not have been good. So we got the proper fuel rail pressure sensor. Made sure it was exactly the right part number for the engine. This is really critical for these engines.
There’s a variety of different, over the years they’ve used this system on Volvos and LR2’s and some of them, these different fuel rail pressure sensors, if you put the wrong one in creates a lot of problems. We had a Volvo a little while ago that someone had put the wrong one in and just created months of havoc for the owner because they lived in a n out of the way town that had a hard time fixing it.
Anyways, put the right sensor in. The readings looked a little better, but still what we’d noticed when we put a fuel pressure gauge, as soon as you shut the engine off, the pressure would just drop down to zero, which is not a good thing.
It’s supposed to maintain a pressure around 30 PSI approximately for quite a while, like at least an hour or two. You know, and then, it’ll probably, if you leave it overnight, it’ll probably be down to zero, but at least there’s still a little bit of, it keeps the fuel on the line. So the thing that normally causes that as a bad fuel pump, there’s a check valve in the fuel pump. So that was kind of our next step in the job.
Mark: So what happened after you replaced the fuel pump?
Bernie: Yeah. So we replaced the fuel pump, it’s a large and you know, pretty pricey job in this vehicle. The pressure was good. Like the fuel pressure was exactly on spec at all times. And when you shut the engine off, the pressure would drop to 30, 40 PSI. It would stay there for a long time. So that issue was solved. So we’d fix that.
Mark: But were there some other problems still?
Bernie: So interestingly enough, the check engine light still stayed on, even though we cleared the codes and this car was still hard to start. So we had it for another day. We tried it the next morning and started perfect. But if you leave it and it got a little warm, it cranked over for a long time. So interestingly enough, even though we had good fuel pressure now, there were still some other issue going on. So we kind of proceeded to doing a whole number of further diagnosis.
The codes, by the way, for the check engine light, were a fuel system, rich code a P0171 and a 174. These are like rich fuel condition codes. So there’s too much fuel getting into the engine somehow. So how that happens, I mean, you could have a leak. There’s a few ways.
So we tested and verified that none of those items were present. We tried a new PCV it’s like a PCV valve assembly on the back of the engine replaced that. That didn’t make any difference. We cleaned the throttle plate. We did a number of things. I was at the point where, you know what, I want to fix this for the customer. We promised we do it. So at this point we kind of took it off the clock and I started going off, trying to figure out what else we could do to solve the issue.
The other area of course, is even though the oxygen sensor, the front oxygen sensors look to be reading normal, they were original. So we recommended replace them. Of course, you know, we charged for that. But you know, after that we replaced those that still didn’t solve the issue.
Mark: So now this is getting into the mystery portion of the program. So what’d you find out? What did you do next?
Bernie: Yeah, so the mystery portion, so I just re verified everything. Is our fuel pressure good. You know what could be causing this? And the last thing it came down to was the fuel injectors. And he’d replace them. So here’s a question, so I started asking him, Hey, you know, where did you get the fuel injectors from? Like where did you source them. And of course being a do it yourself, or there’s lots of options in the internet.
He’d bought them from an auto parts place that I won’t mention. They sell a variety of fuel injectors. He bought some very cheap injectors. Right away I go, I bet you that’s his problem. And having a little further conversation. The sequence of events was, you know, it was hard to start. I figured I’ll change the fuel injectors. So he put them in and it seemed to me from his conversation that maybe that’s when the check engine lights started coming on. Make a long story short. I finally conclude, you know, I think the injectors are crappy. They were probably about, I think he said, they were about $20 a piece.
I looked them up online. They’re about 20 bucks a piece. Not a bad choice. I mean, there, you know, why not go for a low price. The OEM injectors are about $400 each that’s a big discrepancy and you know, you don’t need to necessarily go with OEM, but what you should do, like on a car like this if you can get after market Bosch, which is basically the original supplier for less price, that’s probably the minimum of what you should do.
But anyways, to make a long story short the injector seemed to be the issue and so that was kind of the next stage of the the story.
Mark: So did you change injectors?
Bernie: No, we didn’t. So, at this point that, you know, his bill was very substantial. I figured, Hey, you know what? He said he still had the old ones. So I said, you know, here’s what I suggest you do. I’ve verified everything on the car, take the vehicle back, change the injectors back to the originals and then give me a call and let me know.
Mark: And?
Bernie: So I called him, we had a conversation a couple of days ago. He said, yeah, I just changed. The injectors, starts fine. The check engine lights off. So what are the lessons to be learned from this? Well, as a repair shop, I think asking even deeper questions of which parts did you use would be a very good thing that I’ve kind of learned. After all these years and gray hair, I’ve actually learned, Hey, you never ask all the questions. There’s always something that’s missed. And I made the assumption, Oh, you changed the injectors, you use something good. But you know, there was a question I should have asked.
And you know, I think what happened originally is this fuel pump was bad, which was causing the long cranking over and starting, because it was losing the pressure. But you know, fixing the field pump didn’t solve it because the fuel injectors were bad. So they’re still dumping too much fuel into the engine you know, with the bad faulty fuel injectors cause. So the other lesson, of course, if you’re a do it yourselfer, because I know some do it yourselfers watch this podcast, buy good quality parts. Don’t go for cheap price. You know, you got to make sure what you’re getting, you’re comparing good quality oranges to good quality oranges.
You know, if you’re getting the same quality at a better lower price, then that’s fine, but don’t use substandard quality.
Mark: Don’t put apples in.
Bernie: Yeah, that’s right. Yeah. Yeah. I’m trying to think of an orange comparison, but there really isn’t one.
Mark: Rotten oranges.
Bernie: Yeah rotten oranges on the inside.
Mark: This is also a good example of making assumptions, isn’t it?
Bernie: Exactly.
Mark: Assuming that it’s the fuel injectors and changing the fuel injector and just causing a cascade of issues because you’ve fixed the wrong darn thing.
Bernie: Yeah, exactly. And this isn’t the first time. We had a client who was a GMC diesel truck. We did a diagnosis and said, or actually for some reason he bought the truck and it was an older one, decided I’m going to change the fuel injectors myself, which was a very bold job because even something for us that would take like, well, over a day’s worth of labor, just to change the fuel injectors.
He changed them himself, but he bought some injectors online from a supplier. Within a month there’s problems. At the end of the day, we ended up replacing all this fuel injectors with good parts that we knew were reliable. He ended up spending like way more money. So you gotta get the right parts, but actually paying for proper diagnosis really makes a lot of sense. If you’re just guessing at stuff, you’re gonna waste your money. Sometimes you get lucky, but a lot of times you’ll end up creating a lot of grief and costs. You know, this job costs the owner a lot more money than it could have had he brought it to us originally and we just done our diagnostic and done it.
Mark: Fixed the right thing basically.
Bernie: Fix the thing the first time, exactly. And so, I mean, we have an interesting podcast to talk about out of this and lessons learned for owners and do it yourselfers and shops. Ask the questions.

2014 Range Rover Supercharged, Engine Noise Repair

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver, 24 times voted by their customers as best auto repair in Vancouver.  And we're talking about Range Rovers today. How are you doing Bernie? 

Bernie: Doing well? Yeah, we're talking about Range Rovers again. 

Mark: So today's victim is a 2014 Range Rover Supercharged that had an engine noise. Let me guess supercharger nose cone, timing chain? 

Bernie: Nope. None of the above. This was a different noise this time. 

Mark: So what was it? 

Bernie: There was a tapping noise in the engine and basically like a tick tick, tick, tick, tick type of sound. So surprisingly the timing chains, weren't the cause of the noise. But we did need to do some further diagnosis to figure out what it was. 

Mark: So what diagnosis and then steps towards repair did you have to take? 

Bernie: Yeah so for engine noises, I mean, our favourite tool is a stethoscope. I should have actually brought it in, hung around my neck and looked like a doctor, but it's sitting down in the shop. But it's kind of different than a doctor stethoscope in that it has a big long, it was kind of like a listening piece instead of having the flat thing that the doctor puts on. This has a big, long pointed tip and it magnifies the sound. And of course we stick it up to our ears, like any stethoscope, but when you're underneath the vehicle, you could really hear like a ticking noise right. Inside the exhaust system. 

But it wasn't the exhaust because you could also hear it actually coming up from the engine. I think it was just reverberating through the exhaust and amplifying the sound. But the noise was loudest up in the valve cover sort of under the right bank cylinder bank, valve cover area. So we knew there was something going on, probably a valve train problem, cam shaft, lifter, valve, you know, something like that, where it needed further disassembly. Specifically removing the valve cover to find out what was going on.

Mark: So is that a fairly straightforward task? 

Bernie: No, it's a Land Rover. It's a Range Rover. A Supercharged motor. Now it's not, I mean, a valve cover, you know, one time a valve cover removal was like I mean, I think there's some older Chevy's is like a 10 minute job to take a valve cover off maybe even five minutes.

If you have your tools beside you, but on these things, it's quite a lot of work. First of all, the supercharger has to come off and the intake manifolds. So that whole assembly has to come off. And then from there, the fuel injectors, it's a direct injection, they sit right in the middle of the cylinder.

The fuel injectors have to be removed in order to get the valve cover off. So we have a special puller that pulls the injectors because once they're in for a little while they stick in the cylinder bore. So it's a special slide hammer for pulling the injectors out. So it's a few hours worth of work just to get the valve cover off, to look at the inside.

Mark: Right. You got to cover off. What did you find? 

Bernie: So we found one of the exhaust valves, there's basically two exhaust valves per cylinder. One of the exhaust valves. There's a huge amount of play between the cam lobe and the bucket, which is like the lifter. The thing that presses the valve down on the camshaft. Enormous amount of play, probably like an eighth of an inch like this, you know, you can them kind of look see you in the camera, you know, like quite a lot of play, a huge amount. So it's normally about 9, 10 millimetres is kind of the average specification. This is like, I don't know, I have a hard time converting an eighth of an inch to millimetres, but it was a lot. Very excessive. So we knew that's where our problem was. And from there we had to disassemble, remove the camshaft and go further into disassembling. 

Mark: And was there anything else you found after the camshaft was removed? 

Bernie: Well, I'll show you what we actually found to be the actual issue. 

So our 2014 Range Rover. It's a full-size Range Rover Autobiography Edition, super nice. And the owners put some nice extra large wheels and tires on it. So for that even better look, it's kind of cool too get a carbon fibre hood as well.

This is a view of the valve train on the right cylinder bank. So there's the timing chain. This is the exhaust cam, intake cam and the lifter. The issue we found is right in this area here with this exhaust valve and cam right here. This is the camshaft bucket. This will sit over top of the valve and the valve spring and the tip of the valve, the valve STEM presses against here. I don't have a view of the other side, but the other side is where the camshaft rides.

This is a brand new one. If you look really closely, you'll see a nice round piece here. And these are all very precision thicknesses, because this is how you adjust your valve clearance on this engine. It's a solid lifter. There are about 40 different, I'm guessing 30 or 40 different thicknesses. So you have to get them right. Put them in the right spot and measure them out. 

This is what we found when we took the engine apart. You can see this centre piece completely gone. So there's our eighth of an inch of play. It basically just hammered out, I don't know what happened, whether that's a hollow piece and it hammered it out or what happened, but I'll just go back and you can see the good one  and the bad one.

So that's where our problem was. We measured everything out on all the other ones after repair. We went through and did a full valve clearance inspection. All of the rest of them were good. So we just repaired the one, which was the only thing going on. Now you might wonder, should we have done all of them?

This is the first time we've run into this and we've done numerous engine repairs on these vehicles. So we figured it was basically a one-off issue on this particular thing and all the other valves specked out perfectly well. So there's our picture show of the day. 

Mark: So I'm sure while you had everything apart, you had a look at the timing chains in the Supercharger. How were they? 

Bernie: Well, we actually end up replacing all of them. Actually we're kind of surprised because the timing chains are all actually in good shape. There was no play. We talked to the owner and he said, look, I've owned this thing since brand new, had about 130,000 kilometres on, he says I've never had them replaced.

Like the engine has never been opened up. So he was keen to replace them because he knows it's a problem while it's in there, it's a bit more money for parts, but the labor is not really any more involved. The Supercharger nose cone, like there's a coupler that connects between the pulley and the actual supercharger.

That's the, where the problem lies with the nose cone. And there was some play in that, even though it wasn't really noisy, we replaced that too, because again, everything is apart. Why not do it while it's apart? Little more money for parts, but, you know, saves having to do it again in a few months.

So everything's done, complete. The end of story, it sounded great. Like the engine runs beautifully. Sounds really good. Like not any noise. Really nice. 

Mark: So do you have any idea on why that part failed? 

Bernie: No, I don't. I mean, at first we thought, well, maybe bad maintenance, because a lot of time, you know, it's easy for people to miss an oil change. These are the kinds of things that happen. If you, have not even decided you just get forgetful and you miss an oil change or the warning light comes on, says service the vehicle. They should get it done right away because you know, don't wait. I mean, I say right away, get it done within a week or two. But don't wait for a month or two, or if you've missed something. It's better to service it even before the warning lights come on if you can kind of track it. You know, go, okay I'm just going to change my oil every 10,000 kilometres. It prevents a lot of stuff from happening. 

This engine didn't look abused in any way inside. It didn't have any sludge buildup. So, I don't really know why it could have just been a faulty part or something that just wore, for some reason, things do happen. I mean, even in well-maintained cars, sometimes things just break and wear out.

So good maintenance is a good prevention. It's like eating good food, you know, will generally extend your lifespan and keep you healthy, but it's not a guarantee. 

Mark: And of course, any Supercharged high performance engine, and this definitely is in that category needs to be maintained appropriately.

Bernie: Absolutely. I mean, these engines are under an immense amount of strain. When you think of the weight of this vehicle and these things like take off like a rocket. I mean, they are super fast, you know, there's over 500 horsepower in this engine. It's a lot, and it's fun to drive for a vehicle like this. But there's an immense amount of strain on an engine that can go from zero to 5,000 RPMs in a second. That's a lot of strain. So things have to be in good shape.
