Oil still leaking after Valve Cover Gasket replaced??
I had a valve cover gasket leak and oil was burning on the exhaust coming through the vents.. I got that replaced and got an engine wash. After that it was perfect for about 3 hours, no smells no smoke.
But after that I noticed when I’m pushing the car or driving regularly for a while and come to a stop I’m having the same issues as before. A bunch of smoke in the cabin and a high oil burning smell STILL Anyone know what this might be since I got the vcg replaced already? I added a picture of where the smoke comes from under the hood. |

vcg replaced by BMW or an Indy? anyway, wouldn't be the first time an incorrectly installed vcg continued to leak. you should talk to whoever did that job.
VERY curious though: how many miles were on the car when you first noticed the leak? |

an indy, yea i went back to him this morning my guess is he might've tightened the bolts too tight. He thinks the valve cover could be warped but the bolts are close to eachother so its unusual to warp in my opinion. I was just under 47k miles when this happened. its a 2015 model.

Edit: yanno, as usual i'm thinking M62, S54 etc. haven't yet had this issue with S55. looks like for S55 there's one part # for the bolt/washer, may even be one piece. anybody who has already done this job feel free to chime in on the washer issue.... |

That teamed with tight clearances in these engine bays, weird install angles, and hoses and things in the way, can lead to install errors, and oil free to leak like a sieve. When I first got my daily driver A3 it had an oil leak from the valve cover. Upon removal of the cover noticed a spot on the head and cover where the gasket had been pinched in a weird way, thus the leak. New correctly installed gasket fixed the leak 100% |

I’ve gone this job on various BMWs several times.
This valve cover can be stuck down pretty good. IF you somehow miss removing a bolt AND you start tugging on the cover thinking it’s just stuck down, you can create a hairline crack in the cover. This might happen if you DO remove all the bolts and get a bit aggressive in freeing the stuck cover. Not saying that’s the case here, but if you get a leak that a new gasket doesn’t repair, be sure and check the cover for cracks. |
