A crack in the engine block can cause antifreeze to leak from it, which puts your car at risk of overheating due to the lack of coolant. The most common sign of overheating is a rising temperature gauge and white smoke coming from under the hood.

LNS stitches are the best way to repair a cracked cylinder head or valve seat.Do engine block sealers work?
Engine block sealers work by sealing the engine head gasket leaks from the inside, using the vehicle's cooling passages to transport a sealer to the leak. Most sealers work by accumulating at the leak, and forming a seal using the engine's heat as a catalyst to help cure and harden the seal.Will a car turn over if the engine is blown?
