Mark: Hi, it's Mark from Top Local. We're here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience and 21 time winners of Best Auto Repair in Vancouver as voted by their customers. And we're talking about diesels this morning. How you doing Bernie?
Bernie: Doing well.
Mark: So removing diesel emission equipment. I see actually quite a few diesel vehicles in my area that are blowing excessive smoke. Is this just a malfunction or is someone removed the emission equipment?
Bernie: It could be a bit of both. Now it depends on what age of diesel. Of course, older diesels do tend to smoke. That's a normal part of the way they were. But anything newer, and I'm talking like, 2008 and newer shouldn't be really blowing any smoke whatsoever. So if you see a vehicle, truck, car or anything like that, that's that age and it's blowing smoke, there's either either a malfunction or someone's removed emission mission equipment. And I, I know where you live and you know, I know that, it's very tempting to remove that stuff and people do it all the time around here.
Mark: So why would someone remove the emission equipment when it was put there for an important reason keeping our air clean?
Bernie: Yeah. Well there are quite a few compelling reasons, if you don't actually care about the quality of the air that you breathe or about other people's air. But that aside, a few compelling reasons are it removes the complicated, there's a lot of complication to diesel emission equipment. There are particulate filters. There's a urea injection system to remove, again, to remove particulate. There are catalytic converters that again, reduce the emission from the diesel system plus, we can talk about the EGR cooler. These are more on the, on the engine side of things. An EGR system, which creates a whole different level of issues.
So, you know, to keep a diesel clean, there's a lot of complexity to it. Not unlike a gasoline engine, but diesel emission equipment is sort of new and I think it's, it's kind of finding its way through the system, getting the bugs worked out. Unfortunately a lot of the stuff is really expensive. When it fails, it costs a lot of money to fix, on the other downside, the the fuel economy is not as good on an emission equipped diesel as it is on a non emission equipped diesel. So by removing, simply removing those items, you actually use far less fuel, which is certainly money in your pocket, and you can also get a lot more power out of the vehicle too.
So again, there's a, there's a number of advantages, but of course the disadvantages is a quality of our air.
Mark: So you mentioned that these components, the system complicated as it is, it's probably expensive. How expensive is it?
Bernie: Really expensive, you know, like the I mean, a particulate filter can be three or $4,000.
A catalytic converter, same amount of money. The urea injection system, there's, again, you know, it can be thousands of dollars worth of components and pieces there. So there's, there can be a lot of money, things to go wrong. Generally, these things do last a long time. There's also a number of sensors as well that can malfunction. They're not so expensive, but again, you know, you have like a check engine light comes on. Or it won't go into regeneration mode. It can be a couple of sensors. You know, you could walk out with $1,000 bill. So you know, it's tempting to go, well, it's just you know, spend a couple thousand bucks, get rid of it all.
And you know, but there again, there's a price to pay and we'll talk a little more about that.
Mark: So an EGR, that's an exhaust gas recirculation, is that right?
Bernie: It is.
Mark: Okay. So why would you delete that?
Bernie: Well, there's a number of, again, there's a number of issues that happen with that. What EGR does is it recirculates exhaust gas back into the combustion chamber of the engine and what the effect of that is, it actually cools the combustion temperature that reduces NOx emission. And you know NOx emissions are very high in a diesel engine. So that's, EGR has had been around for a long time, but what happens with the EGR system, you know, Ford 6 litres famous for this, they're EGR coolers would crack and create a whole number of problems. So a number of companies came out with EGR Deletes. You basically get rid of the EGR system and problems are solved. You know, some other companies, that Bulletproof Diesel, for instance, that have come out with basically Bulletproof Coolers where they solved all the issues that were inherent with the you know, EGR, original EGR Cooler. And that basically, you know, that's a basically good alternative. Once you put one of those in, your problems are basically solved for forever, so you can keep the EGR system. But yeah, I mean, the other disadvantage of EGR is it just, and we see this a lot on Mercedes diesels, a number of other smaller truck diesels and car diesels. It just puts a lot of particulate material and carbon deposits in the intake system that can block everything up and need to be removed. So, you know, having that not there would certainly eliminate that problem. But you know, again, there's, there's a price to pay environmentally, so better to keep it on and keep it working and fix it.
Mark: So to remove your diesel equipment or emission equipment from your vehicle, is this illegal or legal to do that? And are the police out there looking for people who've done that?
Bernie: Okay, so legality in the United States, every state in the United States, it's 100% illegal to remove any emission equipment or tamper with anything.
In Canada it's a little more, more of a wild west kind of attitude. The research I've done federally at when a vehicle sold, it must meet the Canadian and federal emissions standards, but once the vehicle is sold, it's really up to each province to regulate that. So certain provinces of Saskatchewan, for instance, at least back a few years ago, it was, it's fully legal to remove any emission equipment from your diesel vehicle. I don't know about gasoline, I assume gasoline's the same thing. It's fully legal to remove any emission equipment and modify it any way you like. I know in Ontario, absolutely 100% illegal, just like the US. British Columbia, same thing I believe. At least if the police know that you've removed anything, they'll order it to be reinspected and setback to original specs. So that's, so that's kind of kind of how Canada works. You'd have to, you know, if you really want to know, you'd have to check each provincial law, but to be on the safe side, better to keep it all for sure.
Mark: How expensive is it to restore them if you get caught?
Bernie: While it costs a lot. And so as I mentioned, you know, a lot of these components cost thousands of dollars. I mean, if you, if you were to remove your emission equipment or are you having to buy a truck that has it removed, make sure you keep everything or you, not advocating doing it, but keep every single bit and piece. If you happen to buy a truck that's got the stuff removed. Hopefully the seller has everything to give you.
Otherwise, I think that makes that truck worth an awful lot less money. I mean, you're looking at thousands of dollars to put everything back back to original, and you know, that would be with the idea of buying, you know, basically the cheaper way would be to buy the, what's missing used and then just get a functional modified. But it's a lot of work to restore it.
Mark: Is it only from trucks that people are removing the emission equipment?
Bernie: Well, mostly, but you know, there are, you know, there are people who remove it from cars, TDI, Volkswagens. We even had a client with a BMW, a diesel station wagon, which is, you know, kind of like a surprising customer, I would think to want to remove emission equipment, but there was some, there was a couple of things that happened in the vehicle and another thing had happened. He said, I'm just going to take it to Alberta and have this stuff removed there's a shop that specializes in that. So, you know, it's everybody. I hate to say it, but people are cheap and self-centred, you know. I mean, I'm a person too. You know, some, but you know, people just, they care more about their own self interest a lot of times and they do thinking about the broader picture. When you think about the air that we breathe, you know, 20 years ago, 30 years ago, I mean, the air quality in Vancouver was far worse than it is now. And the, the whole reason is because the vehicles we make are, they're just far cleaner. They've got better emission equipment, things function properly, and even diesels, you know, I mean they used to stink so badly. You just get, get next to an old diesel like a, I don't know, like early nineties or early two thousands Ford diesel pickup trucks, 7.3 litre. Great engine, by the way. But I mean, just the smell. I mean, you can barely breathe next to it and you get a brand new, a 6.7 litre Ford, you can just have a, you know, the engine is running, you can barely hear it. You can have a conversation and talk beside it. And you know, that's, you know, the technology, the advancements in engine design and also the emission equipment that's put on the vehicle. So there's a tremendous advantage to it.
Mark: Of having the mission equipment?
Bernie: But having it. Yeah. Yeah. Now, I know there are advantages to removing it, as we've said, but they're not really favourable in many respects.
Mark: So isn't it foolish for a shop to actually remove this equipment based on the legal requirements to have that you must have according to the law emission equipment on your vehicle?
Bernie: Yeah, I would say so. Absolutely. I mean, we don't do it at our shop. We have chosen not to do it. I know a lot of other diesel, progressive diesel shops that don't do it either. I know Bulletproof Diesel, it's a company in the US they sell a lot of neat products for, you know, diesel vehicles to make them better. They don't sell any, removal equipment either. There are companies in the US, Edge Diagnostics used to make a tuner that would allow you to delete everything. They got sued for millions of dollars by the EPA. So they're gone and out of business. And there are shops around, I mean, I actually know a dealership not far from me a, I'm not going to mention the brand name, but they actually remove emission equipment from their diesels. And, I said, Hey, how do you guys, you know, why are you guys doing that? Aren't you worried about your liability? No, we just get people to sign a waiver that they're using it for off road use. Well, which is ridiculous, you know, I'm sure it'll come back to bite them at some point. You never know when the government's going to really clamped down. Like right now, they're right now they don't, but, you know, they can. So, yeah, I think it's foolish.
Mark: Any final thoughts on the subject of a mission device removal?
Bernie: Yeah. Well, if you think, hey, no, no one's going to look for it. I'll tell you that I've had a couple of customers in the last six months, both driving Dodge diesels, driving down the road, something happened, there a light flickered or malfunctioned and the police pulled them over. Kind of got a little suspicious that they may have removed some emission equipment and ordered them to have an inspection done to make sure that everything was in order. So those are the kind of simple things that happen. They're not usually cops out about looking, Oh, you know, with flashlights under a vehicle. But if anything happens, they get suspicious, you know, and it's sometimes the little things like a burned out light bulb that'll take you out. So, you know, I don't know my, you know, my final thoughts, keep it there, keep it working and keep our air clean.
Mark: Yeah. For those who want to remove it, just think about removing all that equipment, parking that vehicle in your garage, closing a door and spending an hour in there. Would you do that? Would you want your kids to do that? Would you want your grandparents to do that? They're not going to live and neither are you. If you do that, it's deadly toxic. And then the more research is done, that's the minute particles that come out of a diesel are, are making us stupid, basically and killing us.
Bernie: You know, the particulate from diesel is a carcinogen. It's very fine particle. It gets deep in the lungs and it's pretty serious.
Mark: It's killing people.
Bernie: Yeah, it is. You know, and so you know, again, we're, we're working on ways to get our world cleaner. I mean, when one day all vehicles will be electric and we won't have be having this conversation anymore. But, you know, in the interim, we're doing the best we can with the dirty fuel.
Mark: So if you're looking for service for your diesel vehicle to keep it running clean and legally in Vancouver, the guys to see are Pawlik Automotive, you can reach them at (604) 327-7112. They're also experienced in putting diesel emission equipment back on vehicles so you can call them and inquire about that. It's a steep price to pay. Be aware of that. And this is in Vancouver, BC area of Canada. Thank you so much for watching the podcast. We really appreciate it. Give us a like on the socials and thanks Bernie.
Bernie: Thanks, Mark. Thanks for watching.
Mark: Hi, it's Mark from Top Local. We're here with Bernie Pawlik, Pawlik Automotive in Vancouver and we're talking cars. How are you doing this morning, Bernie?
Bernie: Doing very well.
Mark: So one question that we've encountered quite a bit is basically people buying diesels when it's the wrong vehicle for the use case. So when does it make sense to have a diesel?
Bernie: Well, I think there's a couple of criteria that it makes sense to have a diesel. I'm thinking about some of those wrong things. I've had a number of people in the past who've bought like a... I'm just going to say Ford, I'm not picking on Ford, but they bought some Ford diesels that had been less than reliable. After spending thousands of dollars month after month to fix one thing after another, the thrill and the concept and the idea of having a... I'm going to say a, macho diesel, just wears off really fast and I see them coming back with a Ford F-150 gas powered, something a lot more sensible and what they need. We've also had a number of clients who own European vehicles, Mercedes in particular, where the the engines get carboned up or stuff happens, very expensive repairs and really, a diesel wasn't the right vehicle for them.
So when does it make sense? It makes sense to me for a couple of reasons. If you're going to buy a truck, it makes sense to buy diesel if you're hauling heavy loads frequently that's either in the truck or trailering them. If you're buying a car, it makes sense of you're driving long distances, but not short little start and stop distances. So those are really the main criteria to me of when it makes sense.
Mark: So why is that?
Bernie: Well, diesels need to warm up. They need to run hot and they take a while to warm up even with modern technology and they try to warm it up faster, a diesel takes a long time to warm up. Generally, the mass of a diesel engine, the actual engine block, is much more robust than it is on a gasoline engine because compression in a diesel is very high. The engine has to, it's a combustion, sorry... A compression ignition engine. So it has to compress the fuel, which will then explode at a certain pressure and temperature, but that requires a much more robust built engine. They're heavier, they're bigger and so they require a lot more energy to warm up.
When they're not warmed up, with modern emission controls on vehicles, which are required and they make a big difference in terms of the air that we breathe and the quality of the diesel engine, you can hear it from 10 blocks away and it's much more pleasant to drive because you actually really can't hear the engine rattling away. With all those items in place, it sends a lot of soot and particles back through the engine, they recirculate and things tend to plug up unless the engine's really hot. Then it tends to work really well. Also, a lot of modern emission equipment, like particulate filters require the engine to reach a certain temperature and highway driving is good for them because that tends to burn off the particles.
Mark: So the filters actually heat up and disperse the particles, burn them, and then re-burn them again so that they're coming out of the tailpipe more clean.
Bernie: Exactly. Exactly. They call it a filter. It's not really a filter. It's more like a storage. It's like a storage trap and then things are burned off at a later time.
Mark: One of the things that people do, I know for a fact, is take off all the emission equipment. Does that solve the problem?
Bernie: Well, it certainly solves a problem, a lot of problems in terms of carbon buildup and things plugging. It solves it for you personally, but it doesn't really solve it for the general public. Diesel soot is a known carcinogen. It's very bad. They're very tiny little particles that get in the lungs. A lot of people die from it. They don't drop dead. It's not like having been shot by a gun, you're not going to die instantly. It's a slow process, but it's a big thing. As annoying as a lot of these things are, and I can see why people remove them because the solution of not having it makes a big difference.
There's a lot of diesel trucks that used to get fantastic fuel economy. They put the emission equipment on, the fuel economy drops by 30% or 40%, you remove it, you're back way up to having an economical vehicle. But really, what makes our air in our cities good to breathe is all these emission equipment, even on gasoline engines. I always think that whenever I see an old car drive by and I can smell the stench of the exhaust, I go, "Man, I can't believe when I grew up that all cars were like that." We've done a fantastic job in terms of making gasoline powered cars really, really clean, still lots of CO2, but that doesn't smell and stink and cause at least the ground level pollution that we're used to.
It does make a big difference. Things can be removed, but it's better not to. My whole idea with this podcast is consider before you buy a diesel. Do you really need one? Because they do cost an awful lot more money to fix too. I often think all the money you save on fuel, you're just going to end up spending in ours or someone else's repair shop fixing things. So it's an important thing to look at. Consider is this the right vehicle for you because for some people, a diesel absolutely makes a lot of sense.
Mark: I guess there's a couple of other issues there. Diesel particulate in terms of it's detriment to human health is measured in parts per billion, which is incredibly small. Something over 20 parts per billion. Anything over that is detrimental to human health and there's tons of research on this now. There's literally diesel engine's soot is accounting for millions of deaths worldwide every year. This is not speculation. This is a fact. They can show it when cities like London, for instance, banned diesels from the downtown area, their air quality goes up pretty drastically, but it's also illegal isn't it? If you take that stuff off it is.
Bernie: It is. Yeah. It is illegal to do it, whether you're going to have a cop knocking on your door, probably not. Lots of people do it and I don't. We live in Vancouver, Canada, so they're not so many stringent standards. I don't know. I know California, you actually have to have your vehicle emission tested. Around here, you don't. We used to have it. We got rid of it. The air still seems pretty clean, but you can be a lot looser with your standards around here now. Honestly, does it really matter if you live out in some small town or in the middle of nowhere and your diesel puts out some particular? Not really, but every tight thing where you get more concentrated and lots more trucks and people around, it makes a huge difference really fast.
Mark: So there you go. If you're going to buy a diesel, what's your use case? Are you hauling a lot of heavy loads? Are you traveling long distances? A hundred kilometres, 150 kilometres kind of round trip every day, then maybe a diesel makes sense. Other than that, driving around town in your big 4x4 and not ever using it to haul stuff, probably not the best use case. It's costing you a lot of money. Is that a fair assessment?
Bernie: Absolutely. One thing, we actually didn't delve into too much there was car. We did just touch on it briefly, but I think a lot of salespeople do a disservice to their customers by selling them a diesel vehicle when they're really, again, they should be asking, "How much driving you do at this vehicle." This is something you've got to ask yourself if you're going to buy a diesel car or a SUV, I'm thinking like a Mercedes type of thing. There's a lot of ML320s and 350 diesels around. There's just a lot of them in our area. So many people don't buy them for what they need them for. They really should be buying the gasoline version. I think the salespeople really do a disservice by not asking, "What's your usage?" They're just, "Oh yeah, we've got this diesel. It's got great fuel economy," and people just buy it. Then a few years later, the engine's toast or things are plugged up and they're spending thousands of dollars to fix things they wouldn't have had to do. So just something to look at.
Mark: It's not an around town vehicle unless you're hauling stuff basically.
Bernie: Exactly, exactly.
Mark: Go electric. Anyways-
Bernie: Yeah, that's becoming an option if you just need short commutes, electric might be a-
Mark: Far better option.

Mark: Hi it’s Mark from Top Local Lead Generation, we’re here with Mr. Bernie Pawlik - of the award winning Pawlik Automotive - just winners again as voted by their customers as “Best Auto Repair” in Vancouver. How are you doing today, Bernie?
Bernie: I’m good
Mark: I have a forced smile on my face - we’re going to talk about VW TDI’s - I’m an owner of one of these cars, when we last talked about these we both had high praise for these vehicles and it turns out it was an illusion. They are very fuel efficient but they’re also polluting like crazy because of what Volkswagen has done so maybe you can tell us a little bit about what happened, what’s gone on.
Bernie: Yes, essentially the TDI was sold as a green diesel car. It had everything that people wanted; power, performance, excellent fuel economy and low emissions. High emissions are a common thing in diesel engine along with excellent fuel economy. Power and performance weren't there in the past; but now VW (along with most other manufacturers) combined all three but VW had a few tricks up their sleeve and the emissions weren’t what we excepted them to be.
Mark: So how was VW able to make the emissions low on an emission test and yet have cars that are emitting up to 40 times the regulated amount of nitrous oxide?
Bernie: Well they did some interesting, kind of crafty software programming: - they were able to write code so that when a vehicle was on a dynamometer being tested for emissions it would perform differently. The vehicle used a combination of the GPS system, the steering angle sensor input & wheel speed sensors to tell the computer that “hey this vehicle is not going anywhere, it’s being emission tested.” It would perform what was best for emissions, but as soon as the car started moving up the road, it would go back to its other programming for better fuel economy and performance.
Mark: So there are lots and lots of diesel cars and trucks on the road, how does everybody else deal with nitrous oxide, fuel economy and engine performance - those ultimate 3 things that we all want out of our vehicles?
Bernie: Well what everyone else does and actually Volkswagen does on certain models but not the two litre engines that they sell to North America is use a urea system. It’s basically a tank with an extra chemical that is injected into the exhaust system, into a special catalytic converter and that eliminates the oxides of nitrogen. Volkswagen was originally planning on using the Mercedes BlueTEC system back around 2005, at least some people at VW wanted to use that but others decided, hey let’s develop our own system. They worked on developing their own system and it obviously didn’t turn out as good as they thought. The urea system is an add on, and there is an added cost, however it is very minimal but there is the added hassle of having to add extra fluid to your vehicle every once in a while. It's what everyone else does, even heavy trucks use an urea system for emission reduction.
Mark: So going forward, what kind of options does VW have? I guess it’s VW and Audi and Seat - there’s a bunch of companies that use these same motors.
Bernie: Yes, exactly. Well as far as I see it, they’ve got one of two options. They reprogram the vehicle so it runs all the time for the reduced emission standards; of course the cost of this will be lower fuel economy and reduced performance. This will disappoint the owners who bought the cars for the performance and the economy. Secondly; they can add a urea system which will be extremely expensive for Volkswagen. It will probably take up a bit of trunk space in your vehicle and then you’ll have to add the urea to the vehicle as well. As I said the cost for urea is really minimal unless you buy it at the Mercedes dealer.
Mark: So do we just give up on the idea of clean diesel?
Bernie: I don’t think so, I mean it seems like it works well with the urea system but it’s obviously not quite as what the VW TDI was advertised as being. So yeah, I think the clean diesel works and you and I have talked about the biodiesel option as well as it’s much cleaner than petroleum diesel.
Mark: Well it’s far less polluting. So I guess the big question is how does Volkswagen - why’d they think they could get away with it, why’d they have the nerve to pull off such a stunt - I guess we can’t really know for sure but what is your expert opinion not that, why do you think they did it?
Bernie: Well I think they, as I was saying earlier, were going to use the Mercedes BlueTEC system and then decided, no let’s do our own system. So they obviously did their research and they did their development and found that their system didn’t quite match up to what they expected and they made the choice - let’s just fudge it on the emission test because you know, there’s probably a cost factor involved. You and I were talking earlier: the Jetta’s and a lot of these cars, maybe not the Audi, but the Jetta is a lower end car, they’re a cheaper car so they don’t have the profit margins so, they screwed up and decided to fudge things instead of spending an extra $5000 on the car and putting a urea system in. They probably started with a few cars and they just got so deep into it they keep on going with the “fudging” as I like to say.
Mark: So you mentioned that other vehicles have this, that are using the urea type systems - I know that my dad’s old diesel truck used to get really good mileage and I know that from talking to you that some newer ones for a time there didn’t get as good mileage. So what was going on there?
Bernie: So in the late 2000’s, I think it was a hard time for the diesel industry, the US put some very stringent emission regulations that the manufacturers had to meet. A lot of American trucks, if we can move away from Volkswagens for a minute, went from having minimal emission equipment to now having to add catalytic converters and items for NOx reduction and it just threw the gas mileage in the toilet. They went from twenty miles a gallon on a lot of trucks to eight miles a gallon which is extremely annoying for a lot of owners; and there were lots of problems associated - the diesels just weren’t as reliable.
I might add, we blame Volkswagen the corporation, for doing these kinds of things but there are a lot of diesel truck owners who have removed their own emissions equipment. It’s completely illegal, but we think "well you know, it’s my own truck, I’ll just do what I want" and who cares about the emissions. There are many companies that sell exhaust systems to bypass the catalytic converters and there is software made to bypass the whole system. So there are a lot of polluting diesel vehicles out there, not just Volkswagens, but people do it individually and after-market companies do it.
Mark: And then when, what was the change? That’s kind of resolved itself with the newer vehicles, is that right?
Bernie: Yeah so going forward there are basically the newer generation of diesels, at least the American trucks and pretty much all the diesel vehicles out on the road except for the Volkswagens that use the urea system. That gives you the best combination. You can make an engine that has good power, good fuel economy and then just deal with the excess NOx emissions in the exhaust system with the urea and catalytic converter. It seems to work out well.
Mark: So any final thoughts?
Bernie: You know sometimes it seems innocuous, "oh well, it’s just a little more pollution, whatever." But there are statistics, there are people actually out there dying because of this. It’s not like being shot with a bullet or being run over by a car where the results are immediate. It’s slow, it’s hidden - I mean I don’t know anyone who's died from car pollution, and most of us don’t, but it’s out there. I was just reading that apparently in London, they’re saying 3000 people a year die from pollution of diesel exhaust. I know London is kind of a dirty city and it’s big - but you know, the results are real.
It’s going to be interesting to see what Volkswagen does going ahead: they’ve got a big hill to climb to fix this problem and restore their credibility with their customers and it is probably going to take a long time. The V6 Volkswagen diesels are all fine. There are no issues with those, it’s just the 2 litres in North America that you need to be concerned about. We’ll do another hangout where we’ll talk about what specific things you can expect if you have a TDI Jetta and what you might need to do going forward.
Mark: Awesome. So we’ve been talking with Mr. Bernie Pawlik of Pawlik Automotive in Vancouver. They are an award winning shop, 15 times voted Best Auto Repair in Vancouver .

Thanks Bernie
Bernie: Thanks Mark, talk to you soon.
Just what exactly is a glow plug and what does it do? A glow plug is a heater and is so named because it glows red hot when activated. Diesel engines are compression ignition engines and rely on hot air (under extreme pressure) to combust the fuel. A cold engine with cold air temperatures creates difficult combustion conditions resulting in either no engine start or a very difficult start with smoky exhaust. The addition of glow plugs to heat the cold combustion chamber allows the diesel engine to start quickly and smokelessly. Glow plugs are connected to a glow plug controller which is either switched on by a temperature switch or the engine computer at the time that the extra heat is required. Glow plugs usually cycle on and off after the engine has started for up to two minutes to ensure good combustion.
How do you know if your glow plugs are not functioning properly? There are a few ways based on the vintage of your diesel. On older diesels, around 2000 and earlier models, you will notice long crank over or no start when cold. You might also notice that the engine runs rough on start-up and smokes excessively for a short period of time. On newer computer controlled diesels you’ll rarely ever experience these poor engine start and running issues. This is because, after the slightest glow plug defect is detected, your check engine lamp will come on. With it a stored trouble code indicating which glow plug may be faulty will be logged in the computer.
Almost every automotive diesel (car or light truck) uses glow plugs however there are some exceptions. The Cummins diesel as found in Dodge trucks has no glow plugs but instead uses a grid heater in the air intake. This warms the air as it is sucked into the engine. It only switches on during very cold weather.
How often should you change your glow plugs? Unlike spark plugs, there is no recommended maintenance replacement interval for glow plugs. They are normally changed when either cold start issues present themselves or your check engine lamp comes on with a glow plug code (and after diagnosis it is determined that the glow plug is faulty).
Cranking over a diesel engine takes a lot of energy and your starter motor works very hard. All diesel vehicles have either two batteries or one humongous battery to provide the power for the starter. Starters, due to their size are very expensive, so a quick easy starting engine is much easier on your starter. With the quick start that glow plugs provide your starter lasts much longer, saving you money.
The Ford 6 liter diesel engine is fraught with numerous problems however all of these can be overcome. In this video we will show you what we feel is the ultimate repair solution for the 6 Liter: repairs that will keep the engine performing reliably for years and years.
Many of the 6 liters problems stem from the design of the engine and oil cooling systems. This engine uses a unique system in which the engine oil cooler is mounted inside the V of the engine. Here coolant flows through narrow passageways which eventually plug up causing coolant flow restrictions and excessive oil temperatures. From here coolant flows to the EGR cooler which, due to its narrow passageways also tends to clog. Excessive coolant temperatures eventually lead to head gasket failures and even a destroyed engine if left long enough.
For the truck shown in this video, the owner wisely chose to do the ultimate repair job; a repair which eliminates all the weaknesses of the 6 liter engine. This includes cylinder head studs to prevent future head gasket failures, a Bulletproof EGR cooler plus the bulletproof remote engine oil cooler system. A number of minor but nonetheless important upgrades were done during the procedure including new oil stand pipes and STC fitting on the high pressure oil pump.
Let’s get started:
First step is to remove the bumpers and accessories from the front of the truck then disconnect all items necessary to remove the cab from the vehicle. This includes evacuating the A/C system, draining the coolant, disconnecting the steering column, brake lines, coolant and heater hoses, wiring and much more.
Once the cab is raised the engine is readily accessible and a pleasure to work on.
Stripping the engine down is our next step and the next few photos reveal just that, with the heads, oil cooler assembly and high-pressure oil pump removed.
The many dismantled parts can be seen in this enormous layout.
Next steps include cleaning components such as the block deck and cylinder head surfaces along with the oil pump cover and all of the many bolts and miscellaneous parts.
We are now ready to put things back together:
The high-pressure oil pump is reinstalled along with a new and improved STC fitting. On occasion the old STC fitting would break and when this occurred would crack the back of the engine block.
Following pump installation, the cover is installed and tightened down.
We next move onto installation of the Bulletproof remote oil cooler adapter: this is a complete assembly that bolts in place of the engine oil cooler and cover.
Cylinder head studs are installed, then head gaskets, then cylinder heads. Heads are torqued to spec. During head installation, fuel injectors are reinstalled with new seals, along with rocker arms and bridges.
Covering the valve gear sits the high-pressure oil manifold and installed along with this are the upgraded high-pressure oil standpipes. The original designed pipes and seals would fail resulting in a loss of oil pressure and an engine no start.
To ensure an easy start up the oil system is primed until oil flows from the manifold test port.
We’re now onto installing valve covers and the turbo stand
Next is the Intake manifold along with a Bulletproof EGR cooler, this component has been rebuilt to eliminate the causes of failure in the original cooler. Check out the differences between the Bulletproof’s large tubes and the original’s thin tubes: the durability looks very evident.
Some next installations include the oil and fuel filter adapters and plumbing. Because we are using the Bulletproof oil cooler system the original oil filter is no longer used.
Next comes the turbocharger, the FICM or fuel injection control module and the remaining wiring, hoses and sensors.
Here’s how it all looks from front and back, fully assembled and awaiting the cab to be remounted.
With the cab back down we can now work on installing the rest of the Bulletproof oil cooler system which includes first relocating the power steering cooler near the bottom of the radiator. We next install the cooler, pipes and hoses.
The remote oil filter is mounted behind the left front bumper bracket.
Final assembly requires reinstalling and reconnecting all other under hood components, then filling the cooling system, recharging the A/C and we are ready for start up.
After a successful start up, warm up and inspection for leaks our 6 liter Ford truck is ready to go for many miles of trouble free operation having had all major original design flaws corrected.
VW TDI diesel engines have been around for two decades in several evolutions: distributor type and common rail injection. They are fabulous engines and have always been state of the art, featuring quiet operation, lots of power and acceleration, and best of all their fuel economy allows a trip from Vancouver to Calgary on a single tank.
Maintenance is relatively simple requiring routine oil and filter changes, fuel and air filter changes and rarely, timing belt replacements. Reliability of the engines is excellent however there are a few concerns that occur from time to time. Glow plugs and glow plug system failures occur from time to time.
One other concern is clogging of the intake manifold which happens commonly on late 1990 to early 2000 Jettas and Passats. Over time the EGR valve, located in the intake stream allows fine soot particles to build up, eventually building up so severely that air flow is restricted. It can become so bad that the engine has too little power to pull the car up a hill.
When it becomes this sooted, the intake manifold must be removed to do a thorough cleanout. In exceptional cases the cylinder head must also be removed and the head dismantled to clean the valves. Obviously it makes sense to service the intake before blockage becomes severe.
At 100,000 kilometers it makes sense to remove the EGR valve and inspect for deposits and at this point clean them if present. From that point on, reinspecting and cleaning if needed every 50,000 kilometers will ensure a reliable and trouble free TDI experience; just be sure to replace the timing belt every 150,000 kilometers.
EGR valves cause many concerns on Ford 6L diesel engines: the most common one being that the valves stick due to excessive soot deposits. While there are few simple services that can be done on these complex engines, cleaning your EGR valve just happens to be one of those rare simple ones.
The EGR valve service involves removing the valve and cleaning it with combustion chamber or carburetor cleaner. With the valve removed the intake ports where the valve is installed are also cleaned. Doing this service will prevent many an EGR related driveability concern due to a sticking or plugged valve.
Perform this service every time you replace fuel filters and it will only add to the reliability of your truck.
Diesel engines and diesel fuel injectors have changed remarkably in the past decade: gone are the rattly, smoky, stinky, low performance engines from the past.
Today we have the modern diesel: powerful and quick to accelerate, smoke free and quiet, with the added benefit of low exhaust emissions, and often times amazing fuel efficiency. 60+ mpg in a VW Jetta TDI is common!
There have been many changes that have allowed this remarkable transformation and one of the major contributors is the fuel injector which has undergone an enormous revolution.
On older engines all components within the injector were mechanical. The injection pump, again a purely mechanical device, precisely controlled the quantity of fuel to be injected.
Fast forward to today: the fuel injector’s controls are now electronic and the mechanical injection pump is gone. In its place is the common rail system. What common rail means is that all fuel injectors get their fuel from the same fuel rail under the same pressure. There a two types of common rail system: one with very high fuel pressure and another with low pressure fuel that uses high pressure engine oil to boost fuel to a very high pressure inside the injector.
While solenoids have been used inside the injectors the pinnacle of modern fuel injector technology is the piezoelectric crystal which, when electrically energized minutely changes the shape of the crystal and switches a small fuel chamber on and off. The on/off flow in the small fuel chamber triggers the top of the fuel injector to open and close and in turn spray fuel into the engine. The miracle of this injector is that it allows precise injection control to the millisecond.
Old diesels received only one shot of fuel during their combustion stroke while modern diesels receive several injections at precisely timed intervals and this has created the amazing engines that we have today. Through these timed injections more power is produced and the knocking sound, so common to diesel engines is virtually eliminated.
Well they have their concerns and quite honestly many are problematic. However much of this may be due to recent changes in diesel fuel refining.
In the late 2000s, ultra low sulfur diesel fuels were introduced in North America. Minimal sulfur emission is great for the environment but unfortunately for the diesel fuel injector, the refining process removes some lubricants that are crucial to long injector life. All diesel engines built 2008 and newer have upgraded injectors but those prior will likely suffer early failures.
Injector failures show up in a number of ways such as long crank times or no starts, smoky exhaust (usually black) and rough running.
With the expensive components in a diesel engine, performing oil and filter changes and fuel filter changes at or before the prescribed interval is essential.
Replacing modern injectors is very expensive, typically costing several hundred dollars per unit along with a very labour intensive operation. So you may wonder, what can I do to prolong the life of my injectors and avoid expensive repairs? There are several things:
Change engine oil and filter regularly and replace fuel filters regularly.
These additives will restore the lubricants missing from modern ultra low sulfur diesel and prolong the life of your injectors. While there is addition cost, some of these additives will boost the cetane rating of your fuel and pay for themselves with improved fuel mileage and performance.
The best way to save money on car repairs is simple:
It’s with routine maintenance.
Routine maintenance means that at specific time intervals, based on how much you drive, you have your car serviced following a maintenance schedule.
The very minimum schedule that should be followed is the manufacturer’s maintenance schedule. Following this schedule will make certain that you fulfill all of your requirements should you have a warranty claim. Some manufacturer’s schedules are more thorough than others and a good maintenance shop will review the schedule and make additional suggestions to help further maintain your vehicle.
One oil change every 6,000 kilometers for 60,000 Km equals 10 oil changes and a total cost of around $600.00. A lack of oil changes causing a blown engine is $4,000.00 and could easily cost double that based on the type car that you drive.
An average, thorough timing belt replacement (with water pump, pulleys and oil seals) can range from $1,000.00 to $1,500.00. Neglecting it and letting the belt break puts you back in the $4,000.00 and probably far more expensive price range.
Replacing brakes before they start grinding could be as low in cost as $300.00 but if left until grinding could easily run you $700.00 or far more.
Other Tangible costs:
• Lost work hours
• Arranging transportation to and from the Repair Shop
• The stress of readjusting your schedule
• Being without your car when you need it
Through routine maintenance you will know the condition and lifespan of many of your vehicle’s parts. At specific intervals critical services like oil changes and fluid flushes will be done extending the life of your vehicle.
Will routine maintenance eliminate all surprises? Unfortunately it will not, but it substantially increases your odds of trouble free driving.
So there is your key to save money on car repairs: Maintenance, Maintenance, Maintenance!
Pawlik Automotive is an auto service shop located in the Marpole area of Vancouver, BC. We’ve been in business since 1991 which makes us 20 years old this year. We service most makes of cars and light trucks and we do pretty much all the maintenance and repairs that your car will need. What we don’t do is bodywork, windshields and detailing.
I want to speak today on a few aspects of our business that are unique.
Let’s face it there are a lot of auto repair shops out there but there are several things that make Pawlik Automotive an excellent choice for servicing your vehicle.
We take what I call a wholistic approach to vehicle service. We look at the whole car, evaluate it and let you know what service is required now and what is required in the future.

We don’t use a heavy handed or fear based tactics as a way of selling service.
Another area of specialty for us is fleet maintenance: essentially these are vehicles used for business and most often these would be trades companies: plumbers, electricians, locksmiths, rubbish removal companies and garden maintenance companies just to name a few.
What makes our service so valuable to fleets is our thorough inspections along with accurately recording the work needed and booking future appointments along with reminding them of when service is needed.
Diesel cars and diesel trucks are another area of specialty for us. Many auto repair shops don’t do diesels but we love them and have invested in the equipment and education to diagnose and repair them properly.
Doing proper diagnosis is very important to fixing a modern vehicle and it is a big part of our business and it’s something that we do very well. There are many expensive parts to go wrong so it is essential to take the time to find out what the exact cause is so that our client’s money is not wasted.
Over the past few years I’ve invested heavily into our website and created educational materials. I write blog articles frequently about all sorts of auto repair topics and have created several videos on how we do our work and what makes us unique.
I encourage you to take the time to look around as it explains a lot about how we do things here at Pawlik Automotive.
If you have someone that you’d like to refer to us please ask them to look at our videos as it will give them an idea about how we do things and what makes us unique.
