if you do a compression test and a leak down test on a motor, and the results all came out normal, would that rule out any chance of scratches in the cylinders or worn valve seals?


i guess what im asking is, if you had scratches in your cylinders or your valves werent sealing properly, would you be able to tell from the compression and leakdown test results?
