:!:! this thread has given me hope... cars not been used for 4 weeks and had creamy stuff under cap, only once to drive to garage... fingers crossed all will be fine when its back tomorrow (new clutch)

as joe said, it'd be condensation, the dipstick and oil cap are the 2 highest points where the condensation to go so will go mankey once mixed with the oil, clean it off and give the car a good blast, open it up well through each gear. Check the car again the next morning and if the mayo has returned then removes the pipes connecting to the rocker cover and give them a squease, if mayo starts to ooze out of them then get it down to a garage for a skim and head gasket change!

Good to know :thumbs:

If it has'nt been driven properly for a bit and only moved about and run for a couple of minutes it will just be condensation in the oil. Obviously keep an eye on coolant and temp but it wont be headgasket.

Yep its been stood for a week or so..... or only been drove in and out of garage not used properly :thumbs: i'll check my dipstick... what would it mean if that was mayoie aswell

do you have the mayo on your dip stick as well?

like bieransri said if its stood for a few days then it could condensate. this happend to mine. i gave it a good run out and it went. i gave it an oil change as well a few weeks after to clean out the oil.

not neseceraly (sp) may be condensation if it has not been used for a few days. does it use water or any other unusual things like that?

Theirs creamy bits in my engine oil :o Does it definetely mean my head gasket has gone??? How easy to replace and how????:thumbs: on a monster 1.0 12valve engine v reg
