Dear all, I would really appreciate if somebody could tell me the normal and minimum values of the piston
compression for a 2001
Yanmar 3GM30-YEU
engine. It should be easy to know, but I have two technical opinions, one with 470PSI=33 kg/cm2 (28 minimum) and the other 340PSI=23,9kg/cm2 with a tolerance of 20%-30%.
By the way, the official dealer got 20-15-16 kg/cm2 (284-227-213PSI). Could anybody with a similar experience tell me what should I expect about that?
Thank you very much.
