Re: CD-11’s compression issue

[frankr]

Forgive me while I play detective here. By any chance, did you replace the schraeder valve in your compression tester with a tire valve? That can reduce the indicated readings on the gauge by 30psi or more.

I agree with whoever said it above, 30psi is blown head gasket or blown piston readings. Even slap worn out rings will do that good. Well actually, it shouldn’t run long enough to get them that worn.
