Burning plastic

More bad luck, I'm afraid. Thought I smelled a hint of burning plastic since last repair, two months ago. Haven't really driven but a few miles to work since then. Went across town today, our first warm day, car was smoking when I got home. Definitely burning plastic. Kinda wish it woulda just burnt to the ground, ya know?

Is this the DME / Valvetronic Motor issue ? I read your last post and it sure seems to me like perhaps you need to visit a new dealer.....

Not sure. They're diagnosing the problem now. It is suspicious that every repair done by these people has resulted in another issue. I am done with these people, but since I also suspect the current problem is related to the last, took it to them one more time.

I thought a while back I had a leaky valve cover gasket but spend a lot of time wiping it down and inspecting to find for sure where the oil was coming from. The tiniest of leaks eventually puts a drop or 2 on your exhaust manifold every one drop can smolder enough to smoke all day an smell the plastic/oil smell when I stopped the car at a light or whatever. I never had to add oil, it was just enough coming out to hit the exhaust pipe and smoke away

For me it turned out to be the gasket/bracket around the valvetronic wiring harness at the top of the valve cover. $10 part. which I don't believe comes with a new valve cover or gasket set.



top view showing oil buildup. I would make sure this part has been replaced as well and if not, its only 2 torx screws and removing the plastic engine cover to get to it.

The best thing to do is if you can, as soon as you get home after a long drive at night, pull into a garage, open the hood, and start inspecting with a flashlight or even cell phone flashlight to get into the small areas and look for the smoke that will be rising like a candle smoke off the exhaust pipe and even follow your nose for the smell. Check for oil on the heat pipes and headers and see if it is dripping off the valve cover, and then if it is coming from the higher up valvetronic wiring harness.

As a side note, I have met way too many people who got taken for a run around by mechanics looking for oil leaks buy just continually replacing the most likely cause only to return and then replace the next thing that might be the cause, then the next, an so on.

I didn't read your last post that I can recall but hope when they replaced the valve cover gasket they replaced the plastic valve cover as well. Very common when you remove an older plastic valve cover of any engine to crack the plastic somewhere as well. It's a chance a lot of mechanics don't like to take so usually recommend to replace the whole valve cover and gasket. Especially if you are paying.
