guys took off passanger side head....gasket wasnt blown..i know there is 50% chance could be other head(havnt gotten to it yet) but the car was overheating and there was beige goop on oil cap. Thought blown gasket. SOmeone told me could be cracked block...car was running great besides it overheating every 3-4 days. Would the car run that good and not overheat that often ifi had a cracked block? Seems like that would cause the motor to not run so good. I mean the water pump was shot too so im hoping replacing gaskets (all of them) and replacing water pump will solve problem. What do you guys think???
