If that's true I don't understand how VW engines new are 25-31bar and my rebuilt one is 21-22bar, very very close to the wear limit. I don't trust myself or the harbor freight tool kit to re-test their compression test findings due to the possibility of stripping the glow plug hole or breaking off the test tool in the engine block.
