Another thing I learned at the racetrack about engines and oil. Cutting open your filter each change can give you early warning of problems inside the motor. Race supply catalog and Cyber stores sell a tool to cut open your canister oil filters with ease. Then you spread out some of the paper core and look closely at it to check for metal filings and specs of worn interior parts. I do it while the last of my oil is dripping out, use a magnifying glass. I once found some bronze specs in my 928 filter core and knew I had a bottom bearing problem...We saved that motor by replacing the #2/6 bearing the night before I went to Laguna Seca, where for sure it would have blown..The bearing was spun, sending bronze (or whatever alloy that is) into the oil system to be trapped in the filter paper.. Cheap way to see if anything is grinding any other thing off, inside your engine... Don Hanson |
