What is this sound?

I have gotten rid of my exhaust leaks but I still have this high pitched rattling noise that occurs at the front of the engine - especially when accelerating. Thoughts?

Take the belt off and see if you still hear it.

Noise is gone. So what does this tell me? Belt and tensioner are new.

Perhaps the harmonic balancer? Do those go bad and have a high pitched rattle?

Bearing is my bet with the belt off try wobble /move all the pulley's side to side I think you will find a loose one

Yep, check the idler, that is the next most common bearing to go out. Alternator bearing, compressor bearing, ps pump are less common but a possibility.
