Title: Creamy substance on Oil filler cap
Post by: Snooze on 31 December 2010, 11:34
I have noticed that there is a creamy substance on my oil filler cap when topping up the oil on my 2006 Mk5 Golf Gti.  My head gasket isn't going is it?  Its only done 58k and had a new cambelt at 54k.  Please help!

Could be a bit of condensation.  Do you do a lot of short journeys?

Take it for a cross country blast to clear out the cobwebs :afro:

Take rhyso's advice mate. Just check the engine cooling water expansion bottle for any signs of oil, if there's none, she just needs a good blast on the b roads for a few miles :cool:

When was it's last oil change and also what service regime is your car on? Long life or time and distance?

This was covered a fair bit last winter & it does seem to be down to cold weather & short journeys,my old GTI did the same.

Just had a new Coolant expansion bottle and coolant is fresh and clean. 

Last Oil change was March, and I check the oil level once a month.  It was on Long life servicing until I purchased the car in March and now its on time and distance.

Cheers guys

I had a look in my GTI a few days ago (after seeing this thread) and there is a small amount of creamy substance. I assume this is due to the cold weather and my short journeys.

Just condensation due to short journeys, I sometimes get in the 911, aircooled so no coolant to turn creamy.  A good long journey with extra thrapping here and there should shift it.

Have had the same issue with my GTI from new - scared the crap outta me at first.

Comments in here are right - the technical term is that your oil is emulsifying - condensating at the coldest point which is naturally at the filler cap. I too do short journeys and when you mix in the cold snap it is quite common.

Once you give her a good ragging or just a longish 40 mile or more drive check the dipstick straight away. If the oil on the stick looks well oil like then you are fine if it looks like the brown milky goo then its time to get the cheque book oot  :sick:

I have read that it is still best practice to clean the goo out on a regualr basis.
