compression test
Cylinder pressure check
A compression test measures the pressure a cylinder can generate in an internal combustion engine, helping diagnose engine health.
Low compression indicates worn piston rings, leaking valves, or head gasket problems.
Mechanics perform compression tests by removing spark plugs and using a gauge while cranking the engine: The compression test showed cylinder three was weak.
