Hi everyone,

New to the forum and need some help from everyone! I have had an issue with my 2008 A4 Audi for a bit now and I am at a lost. All the symptoms are that of a faulty PCV valve, but I changed and it is still not working.

I changed the PCV valve, the breather hose and the oil fill cap. The problem still persists. I have oil leakage from the oil fill cap, I have white smoke upon hard acceleration, and a jerking motion upon hard acceleration. I am at a lost as to what it could be. No check engine light so I don't think it's electrical, I have no idea what else it could be! Any help or thoughts would be greatly appreciated. Thank you so much!
