Oil cap

While I was trying to solve my idle - ISV problems, I removed oil cap to
see if I have vacuum leak, and it looks like this:

http://us.f3.yahoofs.com/users/41b0e...RivuBBW4VfwRBN

I changed oil one month ago - some 500 miles (Castrol GTX - mineral
oil). All this time car is driven on short distances (2 - 2.5 miles) to
work and back.

It never looked like this. I am going to drive it on a highway, for some
200 miles to see if it will go away. Is it safe? Is it only deposit
cosed by short distance driving, or am I facing some major reprise?

Looks to me as if you have water getting into the oil. Head gasket ?? Not
a good sign

That's "mayonnaise" caused by water in the oil. Probably because of the very
short trips your are making in cold weather. Buy yourself a bike .

Coolant, probably, but Ivan is running dual fuel (gasoline / LP ) so it could be
a side effect of the LP. Seems to me that burning LP generates water as a
by-product of combusion. This is nothing more than a guess to give Ivan another
possibility.

I am going to check coolant level. I was told that burning LPG generates
water, and that exost silencers will have to be changed more often. But
how would that wather find it's way into oil?

I looked and I couldn't see this white stuff nowhere else but on the
cap. And there can be nothing on the cap because I changed oil recently
myself, and car was not at any mechanic since.

So should I clean cap before or just drive some 50 miles, and then see
if it is gone?

Strange. If coolant was getting into the oil, then I would expect to see
this elsewhere. Perhaps there is some reason it would accumulate as it has
in your image, but I don't understand how. Perhaps one explanation is that
the lifters are hot enough to boil off any moisture and it condenses on the
cap.

Per my initial posting, I suggest you wipe the stuff off and see if it is
back in a day or so. Also, if coolant is getting into your oil, you should
see evidence of it on the dipstick. What's happening there?
