YouTube sample of sound. (https://youtu.be/EY8WI80TIoI)
Car is high mileage LXi. The sound is coming from the front of the engine.
Sound increases with engine RPM. Disregard where the video was shot. The video was to get the sound only. If I could narrow a location the sound seems to be coming from the water pump area.
The prime suspects are:
1: Water Pump (relatively new, no leaks, pump shaft solid, not wobbling as you'd suspect if internal bearings were bad. Seems too loud to be the water pump.)
2: Bearing in the timing belt tensioner.
3: Oil pump.
Minor suspect:
1: Alternator (relatively new, no charging issues)
I took off valve cover. No issues there. Removed top of timing belt cover and looked down into the belt tensioner area. Nothing obvious like metal shavings. Put valve cover back on, with top timing belt cover off and ran the engine. No wobbling of the tensioner pulley, and the sound was not louder. Sound is getting progressively worse over the last 2 months.
Thank you.
