All my cylinders are at 60-65 psi. I verified my compression tool with my air compressor. Reads right at 60, 80, 100, and 120. The book suggests that if an adjacent cylinder is equally low, it would mean blown gasket, or cracked head. But what are the odds of both gaskets failing or both heads cracking and giving the same LOW reading of 65 psi for all cylinders?
