Could you describe the noise a little better? Sounds like it could be one of your pulley bearings going out. Most likely a tensioner/idler or altenator.

slw, he said he pulled the Belts, that'd eliminate the pulleys and all, but, if I had to guess, I'd say a "dry" Rocker Arm, Oil Seal, maybe even a Motor Mount that's loose ??

Missed that part.

Still hard to say without hearing it.
