Im getting a whining noise from the top middle passenger side of engine area.
I can't tell if it goes away when rev'ing or driving as it doesn't get much louder, but you can hear it when idling.
I changed the idler pulley and the tensioner pulley. no help.
I'm thinking it might be something vacuum? but not sure..
see video for noise. taken from inside the doghouse.
