High pitched metal vibration noise

I have this kind of high pitched metal vibration sounding noise, that comes around 3500, without a lot of load on the engine. it's started this just recently.

ideas?

Could be the belt tensioner. Would not be a good thing if it seized. Sounds like the bearing is going.

Heat shield over the right engine mount.

Then check the other heat shields.

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?
