What does a cracked head gasket do?
If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.
What is cracked engine block?
In many cold-climate or cold weather cases, an engine’s cracked block is caused by freezing. When the coolant in the engine freezes, it expands. The frozen coolant pushes against the metal surrounding it, cracking the block, and will also soon cause the antifreeze to leak and the cooling system to fail.
