Hi everybody, I'm new to the forum but I've been reading many past posts to get me up to speed. Just wondering if anybody has experienced the following issue. I have a 2002 WRX 5MT. It has about 73,400 miles. I've owned since new. I keep the engine bay very clean. My problem is I sometimes smell a burning oil smell. I don't mean burning oil coming out the tail pipe but rather the smell of oil leaking onto the exhaust manifold and burning off. I've already been to the dealer a couple of times and they say the underside of the car is completely clean and they don't see a leak. Just from doing my own sniff test, I get the smell on the passenger side of the engine somewhere in between the turbo and the rear of the engine. I do see an occasional puff of smoke but it doesn't happen all the time. There's no oil puddles on the ground. Any suggestions would be appreciated!

Does this happen when it's cold or only after driving a bit? If it's only after driving a little bit it could be your CV joint, very common for that smell to come from the grease hitting the exhaust pipe after the grease heats up and drips onto the exhaust. -mike

It is an engine hot/after driving a while condition. I'll definitely put that on the list of things to check. Thanks for the tip. -eab |

Replying to: paisan (Mar 01, 2007 4:07 pm) -mike I was able to do some more searching this weekend for my leak. I did check the CV joint and it was completely solid. No leaks found there. Since the engine was cold, I was able to feel around the engine without the fear of cooking my hand on the turbo up-pipe and hot engine block. I was able to get hand down the side of the engine and when I got to the bottom rear of the passenger side of the engine, I felt some oil. Not dried up grease but liquid oil. Bingo. The oil appears to be coming from the valve cover gasket bolt right at that spot of the engine. It also happens to be directly over the exaust up-pipe with about an inch of clearance between the two at that point. So, I made an appointment with the dealer (I really don't feel like trying to change the gasket myself - I also have extended warranty!) and we'll see how it goes. Thanks for everyone's feedback. I'll log more after the shop visit. -eab
