    will be interesting to see what people say as mines doing it a little too.
    dont know if its a problem with the ventilation or if the pipe just needs cleaning.

    Don't know what mine looks like and i do at times get that yellow gunk, but a nice little drive normally clears it.

    Well number 1 is the oil separator, all the pipes may need cleaning, plus new separator. You may need to replace a few pipes as they can go hard and brittle, have you got gunk in the dip stick tube. Pull dip stick and check for any yellow gunk on the end, engine flush may remove some and an oil service. But the pipes can get blocked, and cause probs if not addressed.

    Just to add that if the car is only used for short often trips then this can build up the yellow/creamy gunkyness.

    I would recommend cleaning the gunk out and doing an oil flush, keep an eye on it too, I would guess the yellow/creamy gunk will be due to water build up in parts of the oil ways which can really effect how well the oil does its job and could cause to serious problems.

    If the oil has been changed then just give it a good clean mate, to be honest I am not 100% what it does I have never had to do anything with one or even taken it apart to look.

    My 2.8 Six did the same though!

    If your oil is not creamy then don't worry too much about water and oil mixing, if it is just those bits it would be from condensation mixing with oil vapour, as mentioned if the car is just used for a quick trip here and there it can build up quite fast.

    Apparently the "gunk" is quite common this time of year, something to do with water vapour in the air condensating in the engine due to the cold weather and mixing with the oil. It replicates head gasket failure and scared the crap out of me the other weekend when changing my oil

    Edit: Ha just seen that in the 10 minutes its taken me to write a reply someone else has said the same thing

    I did the same, I proper freaked out when it first seen this build up on mine!!! I had not long changed the cly head and gasket so was shocked but kept an eye on it and how I was driving the car etc and you are right it was a colder time of the year and then it pretty much stopped when it warmed up

    Cars, eh!! Pain in the arse!
