Yes, clutch fan is old/wiggles but I mentioned all belts were removed and issue still there.

For the heck of it I went out this afternoon, poured in a small bottle of Marvel Mys oil and fired it up, Minus the Breather cap(ds) or the PCV hose/cap. Ran perfectly for ten mins. As soon as i reconnected PCV she began screeching again. Disconnected it and screeching almost went away, revved motor few blips and came back.

Been playing with these 25 years. This is a first for me.



I wondr if your baffle is making slight contact w/ the rocker assembly
