Opinions On Noise From Motor

I would remove the accessory belt and spin the various components by hand. I suspect one of those components is making the noise possibly due to a bad bearing. Check the belt while you're at it too.

+1 almost definitely a bad bearing on the idlers are on of the accessories.

Sounds like a pulley bearing to me, too.

Spinning components without the belt on may not work because there will be no load on the bearing. A stethoscope may help you zero in on it while the car is running.
