2016 5500 6.4 Bizarre noise w/ video

[wwall]

This is just one of this trucks many strange noises… it also has a tendency to clatter at shift points and at about 1500 RPM, but I haven’t been able to get a good video of that yet.
A buddy of mine listened to it with a stethoscope and he thought it was coming from the left side of the motor & it seems to resonate all the way down the truck.

Note: the high pitched constant noise is the electric water pump we have installed, no concern there

I thought private was the one you could link. Oops! I changed the listing.
Thank you for letting me know.

Have you checked the torque convertor bolts?

That almost sounds like something is loose, like a Motor Mount, and the whole thing is shaking with Motor Running.

Yes. All good.

It seems to get quieter when hot. (185-210)

It's got a good beat. Check for a donut gasket leak somewhere along the exhaust path and even at the manifold. It almost sounds like a big pressure cooker.
