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:

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?

My guess is short trips and motor not up to temperature long enough to
release the water. The 200 mile ride might be overdoing it but a 20 to 50
mile one will tell the story. If it's gone after the ride then it's just
the short trips.

Looks to me that someone put lithium grease on the cap thread so it would
come off easier. Suggest you wipe this crap off and drive the car for a day
or so; see if it recurs. Also, look into the hole at the lubricant on the
lifters; does it look just like the stuff on the cap?

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?

Nothing. Coolant level is OK, oil level did not rise up. Could be LPG
related. Another thing. Around oil cap was an oily patch, so I bended
flaps on oil cap to make it tighter fit to valve cover. Since oily patch
is gone, maybe moist can not go out either, and that could cause
creation of "mayonnaise"?

I would say that if the oil in the crankcase isn't showing contamination and
the coolant isn't leaking out that things may not be so bad. I am not a
chemist, so the effects of LPG exhaust maybe leaking around valve stems
causing mayonnaise isn't something I understand.

If you clean the stuff off, how soon does it build up again? Did you change
the brand of oil to Castrol and then this happened? If so: try switching
back. Maybe there is something in the formulation of Castrol that doesn't
agree with your engine.

Maybe it's nothing to worry about, but it is good to be concerned. Good luck
Yvan!
