Looking for some insight into what this sound could be, I figure alternator pulley, idler pulley, water pump or timing chain issue. I deleted the upper idler pulley as it was worn out but that was not the cause, not running ac belt to rule that out as well.
Just happened this past friday, the alternator is only a year old but the pulley does have very slight wobble, idler pulley is newer as well. turning the bearings by hand they seemed okay. Water pump has never been changed as far as I know, could that be the cause or could it even be timing chain guides?
