I took the dampener off, put the radiator back on with coolant and ran the engine. I let it get fairly hot and I could not get it to make the screeching noise. I can't describe it but something doesn't sound right in that cover area. Kind of like a slightly loose or vibration-y sheet metal type noise when I gave it throttle. Dampener seems fine but there is a noticeable wear mark on the OD (the ~1.6" OD where it goes into the cover) that is about .4" fwd of the aft edge. Next step? Thank you!
