Default Help me identify this engine noise!

Hi all,

I've got a '94 RX-7 with an LS2 swap from an '06 GTO (40k miles, stock as far as I know). Motor runs well but I've had this noise since first turning over the motor and I need to figure out what it could be. I feel like it could be one of the accessories since it's fairly arrhythmic but looking for your input. Thanks so looking and looking forward to everybody's input.

Hard to tell, I would pull the belt off and start it again to see if was one of the accessorizes, just don't run it for more than 1 minute.

I'm going to jump off the deep end but could be your idle pulley, sounds like the bearing are going bad.
