Just wondering if anyone has done a cranking compression test on their motor. Trying to see what others are getting. I got 240psi on all but one cylinder. I got 230psi on #5. I got 1-2% leak down on that cylinder. It is getting by the rings. I guess that one just didn't seal up well. I scoped that cylinder and the piston and walls look good. The rest of the cylinders didn't leak anywhere. Good on GM. The motor is sealed up tight.
