I over headed my car. Stopped let cool for 30 mins, started the engine and put water in radiator. High pressure steam came rushing out. I continued to fill slowly and drove car 2 miles. With in 2 miles the car begain to smoke white and the I parked it. I noticed water in my oil. The car will run but has very little power and will not stay started for more than 5 minutes. I started to drive up on the flat bed towe truck. My car is too low to be pulled by up on flat bed.

Hi OJLOC,

The head gasket is definitely bad. Whether the head has cracked or not, only a pressure test would be able to confirm.
