What happens when you have low compression?

Low compression in one cylinder usually indicates a bad exhaust valve.

Low compression in two adjacent cylinders typically means you have a bad head gasket.

Low compression in all cylinders would tell you the rings and cylinders are worn and the engine needs to be overhauled.
