    Hi I have a 01 S3 and today i took the oil filler cap off and noticed it was a bit creamy, does this indicate my head gasket is on the way out or could it be condensation??


    Cheers

    if its just a small anount, then it could just be condensation from the breather system especially if the car has sat about. I would expect more cross cobtamination in the oil and water if there was a head gasket problem.

    Took it to the local Audi dealer they said it is common to have a little bit of cream on the filler cap with the weather getting colder. Its nothing to worry about now so i can relax a little!!!

    Cheers for your help guys!!

    That stuff is disgusting - always seen in Rover K-series engines LOL. I've seen it in the whole engine and in the expansion tank too.

    Anyone who even considers buying a car with this engine fitted is a fool! /ubbthreads/images/graemlins/crazy.gif

    If the car has been used for short trips that's quite normal. Do a sniff test in the header tank to check for HG problems.

    The creamy stuff is an oil and water emulsion. I would suggest the following checks before starting to get too worried.
    1) Is there any sign of oil in the cooling system? Check the expansion tank. If so, then you may have a problem.
    2) if not, check that the crankcase ventilation system is working and not clogged up. Disconnect any pipes and clean out if necessary. I'm not sure where they are on the A3. Look around the engine there should be a pipe running from the crankcase to the inlet/inlet manifold somewhere.
    3) After you have done this take the car for a longish run. Long enough to allow the engine oil to get hot enough to evaporate any water present.
    If after having done all this there is still a problem then you will have to further investigate how water is getting into your oil.

    I have a '98 1.6 A3 and have never had this problem but I have had it in other cars especially if parked outside in winter.

    Any MOT testing place can check for HC's in the expansion tank too. It may help to put your mind at rest.
