I'm looking for some suggestions on the source of this whine coming from the timing belt area. I've just changed the timing belt along with the idler and tensioner pulleys and auto-adjuster(Gates belt, Dayco components). Previous owner cut the B-shaft belt and put a bolt where the tensioner pulley is, but didn't remove the shafts(I figure that shouldn't hurt me for now, it's not a daily driver). I'm using Miller tool# MD998767 to set the pulley tension and have tried both the 5/32" drill bit between the auto-adjuster / tensioner arm method and the grenade pin slide-in/out method - belt tension seems perfect. Cam/Crank timing is right on, oil pump marker even lines up(just because).
The whine is heard from idle all throughout the rev range. I started removing accessory belts and components until it was eventually down to just the crank pulley with no front cover...it's definitely coming from the timing belt/component or oil pump area. I've pulled the belt and all components off and checked to make sure they weren't damaged and move/spin freely, and re-set my timing and tension a dozen times. I didn't run the engine very long before I changed everything out(the old T-belt had a few gouges in it) so I can't say for sure the whine was there before.
Anyone have any thoughts or suggestions on this?
