Resolved 2G Timing belt noise

It comes with a video. At idle everything is awesome, but if I blip the throttle or hold it anywhere above idle, I get this buzzing noise, almost like the toothed side of the belt or something is hitting the timing cover. Obviously, it's not the teeth since that would be nearly impossible.

The timing belt, tensioner, components and BS belt were all done by a competent previous owner. I pulled the covers off and re-checked the tension on the belt and everything seemed fine as piece of mind before I realized this noise existed. I'm days away from having this car back on the road (running but trailered it home) but don't want to drive it with this noise and the potential for it to cause large issues. Obviously the next step would be pull the belts one by one and inspect for the noise, eventually leading to a full cover off scenario.

Have any of you heard anything like this before? I figure, if it were something rubbing the timing cover, it would also happen at idle, otherwise I'd dive in and start ripping accessories down.

Watching this thread as I have the same noise. I don't have power steering, a/c, balance shaft and I don't have any of the timing cover.

Interesting. My 1g is bone stock and has a sort of whine at the timing belt but not a buzz. Is your belt tension adequate?

Myself and the owner have re-tensioned the belt a total of 3 times.

I replaced the hydraulic tensioner and set the tension exactly as I did the last time and the issue has been resolved.

Was it too tight or too loose? I had already swapped out tensioner so and nothing changed.

It was probably too loose. A too tight belt will make a whine, like a supercharger.
