Help Identify This Noise

[JBelt01]

I’m hoping that one of you can help identify this rattle. It appear to be coming from the front drivers side.

Sounds plastic-y.
Is it RMP related?

It’s only present at idle. Slight gas and 100-200 rpm increase and it goes away. It’s also more pronounced when at operating temperature.

stethoscope time. I'm going for worn bearings on the generator. an idler pulley... the coupler on the S/C.

I think there’s a good chance it’s an idler pulley

Is there a prize for the first one who guesses right? Without a stethoscope we are all shooting in the dark.

 

[JBelt01]

I’ll have it diagnosed and report back. Prize is 500 internet points, redeemable for an exciting chat with Jessica, 18/F/CA. Webcam is broken.

Looks like your oil cap is vibrating in the video. Make sure it is tightened down and not cross threaded. Or could just be the noisy fuel injectors on this DI engine. But I agree stethoscope would be best to zero in.
