I know my old 93 would start to make a bit of slapping noise when the oil started to get old. I think I was using 15W40 or 20W50 when I had the supercharger on it. I could really tell the difference and an oil change would quiet it back down. When was your last oil change? Do you still have the AIR system installed?
