I posted this same thing under "water coming from exhaust" but i thought that was kind of funny. Yesterday i let my car run in the drive for 20 mins or so. Then i noticed anti-freeze coming from the overflow cap. So i shut it down then poped the hood and heard the anit-freeze boiling. My temp gauge said it was alittle on the hot side but not overheating. I started it up today and it ran fine but there is a lot more condensation coming out the exhaust and a little steam. Does this sound like the beginning of a head gasket problem?
