This is because a cracked head may allow coolant to leak into one or more cylinders or the combustion chamber of the engine.

This causes the engine of exhaust gaskets to lose their capacity to seal the internals properly and as a result, the internal coolant loses its ability to work properly and starts giving out fumes.

Apart from this, a cracked engine block or head gasket failure caused by overheating can also be the reason for the dis-functioning of the exhaust.
