I noticed last week that I had a small amout of yellow/white residue under my oil filler cap so thought Ah! do I have a head gaskett problem. I wiped it clean and again a week later it is back again. This is not thick sludge or even that much, it is very thin and swirled in with the small amount of oil that is on the underside of the cap.
I went to the MB this morning and they have said that it is normal for the 202 petrol cars to have this as it is caused by a small amount of condensation forming under the cap. Your opinions please, can people have a look at their under sides :) .
Cheers

Mark,

The dealer is correct, its nothing to worry about. In this sort of weather the (hot) engine will cool relatively quickly and condensation will form in places like the oil filler cap.

Cheers,

Greg

I would look for you but I don't have my car atm, however, I can tell you that your car is infintely better than an S reg Polo saloon :p

If you want I'll have a look-see when I get the car back.

Do you do lots of short journeys-this will tend to form the "mayonaise"that you describe if the engine does not reach a high enough temp to burn condensation off,allthough it sounds a lot better than the Honda**500 i had once with a knackered water pump,that turned the oil to a sludgy,grey,gelatinous,frothy mush(still went on to do 145,000m though!)

An old trick I remember doing was when the weather was very cold (winter)I put silver foil over half to three quarters of the radiator.It warmed up a lot quicker but i only used to do short journeys of about 5 miles at a time.

I do a mix of 5 min and 45min runs to sounds like the short bits are causing it (it is only a very small amount)
Thanks guys (putting my mind at rest :D )
