If an engine overheats the metal parts expand and the engine will seize up. A seized engine is usually unrepairable.
Anytime the engine overheats you have the possibility of blowing the head gasket.
Normally it will last the life of the engine. However if the engine overheats the gasket can be ruined immediately.
Until it overheats, runs out of oil or gas, or has a mechanical failure.
The engine overheats and parts can melt, crack, even explode (massive expansion due to heat.)
