moisture of some form. Are you losing any coolant? Sometimes can becaused by a high moisture content in the air. Or I heard making a bunch of short drives can do it. I have it on mine from time to time, but and my car never needs coolant
also what does the oil on the dipstick look like

Moisture will rise to the highest point ie the oil fill cap. Mainly due to the lack of the oil getting up to operating temperature ie 180-210 degrees to burn off the moisture. During summer this is normally of no concern but in the winter it comes around.

all the conditions you guy said is true. I thought it was because drive it so hard but I dont drive far and it's been raining like crazy.Thats a good feeling it's not a bad head gasket because there is no coolent missing nor water in the oil . thank guys
