Still have t he noise, Update,

Still chasing this horrrible sound. Went to the AC shop and they said exhaust, exhaust shop said motor mounts, Anyway, I have installed new motor mounts, cut off the exhaust and installed new and replace the R$ with another AC delco R4 and the sound is as bad or worse.

the tensioner, idler, belt, PS pump are all new. The water and alt are 3 years old and show no signs of failure. Today i will remove the york OBA completely and if htat does not fix it I will do the alternator tomorrow.

I will try to take a video of the noise in the event someone stumbles across this thread with the same issue in the future..
