What causes a compression leak in the head gasket?
More likely however is the scenario where the pistons themselves are intact, but the piston rings were damaged from overheating and are failing to seal the gas inside the cylinder. If you have low compression in all cylinders, this is often the culprit. Also, your compression leak may not be in the pistons or head gasket but in the valves.
