The Infiniti I35 uses the Nissan VQ35DE V6 engine found in many models of Nissan and Infiniti cars and light trucks. This is a great engine: smooth, powerful and best of all, very reliable. In spite of these attributes this vehicle came to us in a very unhappy state with several noises were emanating from the engine area. They were so loud that, as the vehicle owner put it, the radio would not drowned out the sounds.

We performed an engine compartment noise diagnosis which consisted of two lengthy road tests with the vehicle warm and cold along with underhood and undercar inspections. Several interesting things were found: the timing chain had a horrible rattling sound and this was most noticeable when the engine was started cold. A loud rattle was present from the exhaust system and the engine had a horrible knock and pinging noise under certain throttle loads. Further inspection found the engine oil level very low, and the oil was old and dirty. Interestingly enough, the check engine light was on and we scanned the vehicle computer for codes where we recorded a P0021 stored code. This indicates an overadvanced cam timing from position A sensor.

From this information we determined that the low and dirty oil was likely causing both the timing chain rattles and the P0021 code because both of these components require clean engine oil and a full capacity to operate properly. After a hot oil flush and an oil and filter service the timing chain noise completely disappeared. This was great news for our client and it brings me to the moral of our story: do not let your engine oil run low and do not let it get dirty. Check it regularly and change it regularly. Modern engines are just too complex and expensive to damage by such simple neglect.

The other two noises were simply repaired by an overnight combustion chamber cleaning and repairing a loose exhaust shield. With all three of these repairs the vehicle sounded quiet and the radio was no longer required to mask horrible engine noises.

2000 Infiniti QX4 – Major Front End Repairs

Infiniti QX4

Our latest featured post is major front end repairs performed on an Infiniti QX4, brought to us by a client from Vancouver, BC.

Infiniti QX4

2000 Infiniti QX4. For the most part this vehicle is a Nissan Pathfinder.

Never, never, never, drive a vehicle when something makes a loud clunk, the steering wheel sits off center and there is a loud scraping noise while driving. The owner of this Infiniti QX4 experienced just these issues and took a chance at driving to our shop for repairs. By the grace of god he made it, for when we backed the truck up, turned the steering wheel and proceeded to drive into the building the front end broke apart and the left wheel flopped out. Had this broken apart on the road, which would happened within a kilometer, the damage would have been catastrophic.

The left front wheel sitting angled out and wedged against the front fender.

Upon inspecting the vehicle we found that the left lower ball joint had broken apart. The clunk and sudden shift in the steering wheel was due to the ball joint breaking and the grinding was caused by the top of the ball joint rubbing on the axle. Numerous other front end problems were found: worn out right ball joint, broken sway bar end links, loose wheel bearings and a damaged brake hose. After all was repaired this Infiniti QX4 was safe once again.

As a vehicle owner it is critical to have your vehicle inspected on a regular basis. Don’t assume that it’s safe. In cases like this ignorance is not bliss, and it cost this vehicle’s owner several hundred extra dollars for repairs. Had he driven another kilometer that cost may have been in the thousands, or if the ball joint had broken on a curve on a mountain highway: well, I shudder to think.

The Infiiti QX4 is essential a dressed up Nissan Pathfinder. It’s a well built vehicle and because it is essentially a Pathfinder, parts are easy to find and are reasonably priced.

The green arrow points to the axle shaft which has been badly ground down from rubbing on the top of the ball joint socket assembly.
