I just compression check my JDM 7MGTE motor and got 150-160 psi for all 6 cylinders. My repair manual says that stock compression should be 142 psi per cylinder. I have stock internals and a Greddy 1.5mm head gasket and have not had the block of head milled. What could be causing such a high compression check, not that I'm complaining.
