How do you blow a head gasket in a car?

The biggest cause of a blown head gasket is overheating. Usually, the head gasket armor around the cylinders can become crushed, and if this happens, the seal is lost and your engine will lose compression, leak coolant, and the gasket will erode.

Leaking coolant and combustion gases can cause high temperature gradients leading to erosion of the leak area and possible cracking. For all these reasons we don’t recommend driving with a blown head gasket. The good news is there is a quick and easy way to seal your blown head gasket and keep your car on the road.
