Creamy brown Mayo but no coolant loss?

[4/4 dirty dervs]

my cars been off the road for a couple of months. I've been starting it occasionally manoeuvring it around fixing odd faults and going for the occasional blast and back. Today I took the oil cap off to have a look about because it seems to be leaking oil out the rocker cover all over the place. Where I noticed a slight bit of milky substance , but under the little recess where the cap screws onto I found thick creamy brown stuff. Instantly I've sh*t a brick thinking head gasket. But the coolant is clean and the level hasn't dropped. Any thoughts?
Thanks

I think these engines do leave a little mayo on the cap if not taken out on a run for a while. It's to do with the engine getting up to temperature. Mine does if I don't use the car much, doesn't appear if I give it a good blast regularly. Keep an eye on it, should be fine.

I'm keeping my fingers crossed that it'd not the HG! By the way does yours condensate a lot on start up by the way?

- 1 by the way lol

Mine does have a fair amount of condensation when the ambient temperature is cold and in traffic, even when when warm.

Take the car for a drive and get it hot, give it an Italian Tune Up and check the cap again. Should be free from mayo.

Head gasket troubles would be excessive mayo anyway. If it looks like this then be worried http://i807.photobucket.com/albums/yy352/howie52/IMG-20101231-00040.jpg

I won't lie, I had to google Italian tune up lol but ok I'll try not to fret until I give it a good run. and yeah same mine is quite excessive when it comes to condensation and acts exactly as yours does.

Just to confirm when mine doesn't get used to much I also get the mayo. Nothing of concern. Also condensates a lot in colder ambient temps like we are having at the moment.

i think most cars suffer from the mayo oil at this time of year

just had a quick look under the cap and its not like ive just opened a jar of hellmans like the picture posted above so hopefully is nothing to worry about.

My previous LCR with the 1.8t suffered from this due to the amount of short journeys I done, perfectly normal.

I had this with my old Astra 2.0t Sri pretty common from what I read. Like mentioned above it's to do with short journeys and condensation in winter etc. Just keep an eye on your water to make sure it isn't anything serious though
