Default 2007 bmw 335i oil leak??? - 09-04-2015, 09:11 AM

Hello I recently changed my valve gasket cover and both oil housing gaskets and I am still experiencing oil leaking onto the silver tray. What other gasket could be leaking. It is not a ton of oil leaking but I can see it accumulating.

Could be rear main seal, turbo seal, etc.. I've recently found out as well, there's several different items on our cars that can cause oil leaks.. sucks..

Are you talking about the metal heat shield that runs parallel to the engine on the passenger side? Your VC may have a crack in it.

Yes that is what I am talking about. Already replaced the valve cover. Unless the new one has already gone bad haha. Anywhere else it could leak from and end up on the heat shield??

I see you mean the actual valve cover not the gasket. I will
Look into that. Any way to check to see if it's cracked for sure.

I'm sure there is a way to check, but someone else will have to chime in on to check that. I do know that it's not uncommon for it to crack.

Checked the valve cover and no cracks. Do you think the gasket could still be bad??

Clean the area around the valve cover and see if new oil forms. Also, as far as it 'still being bad'...not to bash or anything, but did you try to use any other rtv/silicone to assist in the valve cover gasket? Sometimes when people change gaskets they use rtv sealants to help 'bond' the gasket to the metal and unfortunately those sealants can cause uneven contact. Not saying this happened, just a possible. Since you are asking.
