That number is too high to do the oil test. The extra oil alone will bump that number back up to normal whether your piston ring is bad or not. I suggest a leak down test. Have you done a valve adjustment recently?


I was pretty sure that I had a cracked ring but it turned out to be burnt/cracked valves. I had only 120psi on that cylinder.
