Oil cap condensation?
#21
I saw the milk oil cap on my 97 about a month back, and went into a panic thinking I had a leaky head gasket. It burnt off after about 30 miles of highway driving. The UOA didnt show any coolant in the oil either. I checked the oil on my girlfriends 2008 cobalt 2.2 the other day and it even had a NASTY looking oil cap. Temperature was around 10F.
