Drove it only lightly after noise started; shifts fine, no error codes.
I replaced timing belt (+tensioner & water pump) & serpentine belt since it was time and I crossed my fingers that it was just belt rub. Nope.
Syncs with rpm, especially noticeable when shutting engine off and pretty loud from the cabin even when driving. Oil is good. Same noise w/ serpentine belt removed.
Does anyone have any ideas or tests I should run?
