Is there white smoke coming out of the exhaust? That is a dead give away, but does not happen every time.If your car is overheating with adequate water, that is another symptom.And with newer cars like that, I would say that you need to take it to a mechanic. You don't just file the points and keep driving anymore.Firedogfire, you are a little confused, you are talking about the valve covers and valve cover gaskets. The head gasket is between the head and the block, and is not something you just look at.
