Poor compression of both fuel and air inside a car engine is a recipe for disaster.

One of the easier engine faults to diagnose is leaking engine coolant.
What does it mean when a motor is blown?

If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced.

What does an engine seized sound like?
