What does head gasket smell like?
A faulty head gasket most often results in billowing clouds of sweet-smelling white smoke coming from the exhaust. Thie smoke is caused by antifreeze leaking past the gasket and into the cylinders, where it is turned to steam as part of the combustion process.
What are the signs of a blown head gasket?

Can a blown head gasket cause an engine misfire?
Therefore, a blown head gasket can result in a loss of compression and an engine misfire. In some instances, the oil and coolant passages can breach at the outer perimeter of the head gasket. When that happens, you’ll have an external coolant and/or oil leak coming from the engine.
What is the purpose of the head gasket?
The head gasket, which is located between the engine block and cylinder head, seals the combustion chambers to prevent compression loss. It also plays a role in sealing the coolant and oil passages running between the engine block and head.
What causes a head gasket to need to be replaced?
5 problems related to head gasket failure (and how to prevent them) An overheating engine. A head gasket failure may have been caused by an overheating engine (as a result of a clogged radiator, faulty fan, etc), but in turn a Loss of power. If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. Oil contamination. Smoking. External leaks.

What is a bad head gasket?
But basically a bad head gasket means engine death in two senses. One is that with a bad enough breach the engine will run very poorly or not at all because there is no compression.
