Accepted Answer

To check engine back compression, perform a compression test using a compression gauge.

Connect the compression gauge to the spark plug hole of each cylinder.
Disable the ignition system and fuel system to prevent the engine from starting.
Crank the engine several times and record the compression reading for each cylinder.
Compare the compression readings to the manufacturer's specifications.
Low compression readings may indicate worn piston rings, valves, or head gasket issues.
High compression readings may indicate carbon buildup or a restricted exhaust system.
