Just Serviceing?mayo?

[black400]

I am serviceing the 99 reg , rain stopped play , a few things , again oil filter and sump not overtightened, but when i took off oil filler cap a yellowy mayonais substance was in the cap, now since the Missus uses it 99.9 percent of the time 3miles to work ,Could this be the cause ?also since i last drove it millage is down from 28.6 to 16.9.

And no engine underlay so have to have a word with mechanic, why dont they tell you this , HAVE TO SOURCE ONE .

ps checked cooant for singes of oil , none , The seat had the same problem ( same journy) so ill have to take it twice a week to give it a good run , oil and filter change every 3000 miles.please share your taughts

If I see a mayonnaise type substance under the oil cap it says Head Gasket to me fella. I had a head gasket go on a BMW 3 series. The coolant was fine, no oil. But the oil had coolant and made the mayo type stuff :(

Ye me thinks get it checked, i will be keeping a close eye on it , new oil and filter? fingers crossed.

sometimes you can get a little condensation in the engine..... and thats how a little water gets into the oil.

I dont know if this is compounded by all the small journeys.

As for the MPG, I am not surprised, the car will only be warm for half the time.

Just clean the oil filler cap and enjoy happy motoring.

Have you noticed the water level dropping? Keep a very close eye on it. Mike
