Why wont my Buick start after it ran hot? It turns like it's trying to crank. Is it because it's still hot? I didn't blow the motor. It's not knocking. Can't be gas line. I turned the the car on and listen for that.

Hello, 

Thank you for writing in. You may have blown a head gasket. Check the oil, as a blown head gasket would allow the oil and the coolant to mix. When coolant is mixed with the oil it becomes frothy and turns a milky brown color. There is also a possibility that overheating the engine caused the pistons or heads to warp. This would result in a loss of compression, meaning that the engine would be incapable of starting and running. Only further inspection will tell.
