I just got my car running again after a rebuild. It runs great, just like it used to, except for a strange whining noise near the left side of the engine (belts area). I can hear it over the engine noise when driving, and it becomes more high pitched at higher RPMs. I took each accessory belt off individually and still heard the noise, so it's not my alternator, AC, power steering, or the water pump. I also re-tensioned the timing belt to make sure it wasn't too tight, and checked to make sure the pulleys were spinning as expected. When poke around with a screwdriver and listen for the noise, it's loudest on the water pump but I can't reach much else in that area.
I replaced the timing covers, and the oil pump, but not the timing belt or pulleys because they were replaced not too long ago.
Any ideas what this noise could be or what I could check next?
