There was a factory bulletin about double checking to be sure the fill cap was being tightened properly. It's pretty easy to get the cap cockeyed where it doesn't seal. Sometimes this will make a vacuum leak big enough to set off the CEL. Here is a link.

I have had the valve cover replaced 3 times because of a failed PCV valve. this time I noticed the smell of burning oil and thought the valve cover was leaking again. but I discovered it was the oil filler cap leaking. Got a new one and it still leaks. More like a small seep. Wonder if the opening on the valve cover is damaged. Did the vaseline trick work? I was thinking of using a bit of form a gasket around the cap itself, let it dry before putting it on. Any ideas? And no. Never letting Chevy touch it again.

I have the exact same problem on my 2011 Chevy Cruze LT. I also had throttle body issues. I have noticed there are several recalls on my car and after just 1 year I extremely regret ever buying this car.

That said, I am willing to fix it. I have a friend who is a former mechanic helping me too so I have no excuse to spend money at the dealership.

I have only found a few folks who've experienced this problem exactly as I have described with no real explanation as to how the issue was finally resolved I will come back to update to help others.

I have a feeling my finances and landlord are going to hate me for a little while. I suspect the problem lies deeper into the PCV system. There are two more check valves as part of the PCV system that I will be checking on. I suspect the extra pressure is coming from a sort of clog in the PCV line causing excess pressure to build in the block.

After I replaced my throttle body earlier tonight I got into the car and experienced much better throttle response but after only a few minutes of driving my car began to buck and want to stall. I nearly got stuck in someone's drive way. When I got it back home and popped the hood I discovered oil all over my engine compartment and the exhaust was glowing red hot and the Vaccum Regulator Diaphragm broke.

I have to replace the valve cover now no matter what but am going to end up replacing the manifold/pcv system. I am crossing my fingers as hard as I can that the problem will then be resolved.

The only other things I can think of might be injectors or something? I don't know.

If any professionals out there read this let me hear what you think!

I'm taking a wild guess that the had to replace the intake manifold for a missing PCV flapper. When it goes, the turbo pressurizes the engine bock and oil will leak from any place it can find.

Ya man that's what I was afraid of. I did find one on Amazon for 40ish bucks. Just rather not lol it still runs well and has for a long while but figured with everyone elses being an issue mine might eventually.

Oh heck. I'm on my second valve cover. When the last one arrived it came with a warning to also replace the intake manifold. Now the cap is leaking oil for the first time. Sounds like this could be the cause?

I'd check the manifold to see if the valve is still there.
