sound that sounded like you were taking a screwdriver and hitting some dense metal. Hard to locate but sounded stronger on the bank of the #1 cylinder. It progressively got worse until I fu@%ing crunch my journal also and that sounded like metal grinding though a machine. Need to pull the pack and see if at idle the sound comes like say 1 time every sec or slightly less. If it's more frequent than that then I don't think it's the bearing.
