addition, the compression pressure decreases as the engine parts are worn and lose durability through use of the engine for a long period. Scratches on the dust or foreign matter through the soiled air cleaner element, and wear or breakage of piston rings also decrease the compression pressure. For this reason, diagnose the engine status by

measuring the compression pressure.
