Water in the oil!

Meal! The other day when I looked at my 850er 2.4 10v again after the oil, I noticed the much-loved milk coffee-colored mucus on the oil cover and on the measuring rod. My brain of course first switches into panic mode because I could not afford a cylinder head gasket exchange. Now, however, I lack the other symptoms of a broken cylinder head gasket. Although the cooling water disappears something, but this is due to a small leak on the cooler. It smells neither according to A. The car has been moving a lot in cold weather lately. Can it be that it just formed condensation water or something like that? After I drove a little long distance the slime had definitely disappeared. But came back sometime after the short distance rides. So I should panic or just drive the long distance often to blow out the water?
