hey guys
noticed my 08 9-3 has started leaking oil, at the valve cover and also down I think at the front main seal, maybe its the timing cover leaking,
180k miles always serviced, turbo shaft has no significant play, its a biopower so never had the intake valve problem
starts and runs ok but has been a bit boggy and unresponsive in more recent times, no codes on obd2, it does have a faulty fuel gauge but that shouldnt be affecting anything.
noticed today that the oil filler cap is puffing quite a lot at idle which makes me think blowby is causing my oil leaks, havent had time to do a compression test yet but as the car runs generally well not rough I dont think it could be broken ring or piston on 1 cylinder?
wondering whether or not it could be faulty PCV valve pressuring these gaskets and causing leaks - all 4 of my spark plug wells were full of oil at last spark plug change which had never even been the slightest issue before ? now bit of confusion a few catalogues seem to suggest the PCV valve is inside the intake manifold but I thought that was only 2003-2005? I do have WIS but havent had a chanc eto fire up my windows PC and just thought i'd get a few opinions for interests sake.
Cheers
