Strange Metallic Whirring Noise

Have you tried feeling the oil pan for maybe a windage tray rattle?Or the oil pick-up fell down onto the pan?
But yeah, I watched the video with headphones on about 8 times before the odd noise kindof made itself known.Then I listened a buncha more times.

Yeah I know...it's hard to hear unless right around the car in person. Through the exhaust rattle and typical exhaust note, it's there.

Thought about the pickup but wouldn't oil pressure be way down?

I'll try to fab a stethoscope tomorrow.
