HI
I am not having any luck with digonosing this noise. the noise sounds like a belt squealing just not as loud. could i have spun a bering? the engine is a 66 440 and runs great other than this. oil press is above 30 @ idle. i have disconceted the belts to find the noise still their. it just started squealing today and all i did was start it to let it run because it doesnt run much in the winter months it is coming from the front of the engine. did i destroy my 3000$ 440?

and also if i let it sit and cool the noise doesnt come back for 1 minute or so.

thanks in advance
