Is the oil running out on the ground or through the CAC?
The drain tube wouldn't cause a sound like that, and is unlikely to plug due to it's large diameter.
It may have come loose from the bottom but still wouldn't make that kind of noise.
If the pressure line kinked or coked off (again unlikely) a free-floating bearing that's seized, could, but ours aren't free floating.
Look at the oil feed line to see of the oil is coming from the banjo fitting there.
When the engine has cooled, pull the filter box and intake hose out, and the turbo-to-CAC hose.
Look in the compressor intake port and see if there's anything stuck between or against any of the inducer blades.
Spin the compressor wheel with a finger, and see if you can feel what you're hearing. There should be no sound, no resistance, shaft centered in opening, and silent free spinning.
Spin it and then push directly in on the center shaft as it's spinning. If it stops immediately you've found the problem.
Grab the compressor housing and see if you can get any movement. It's unlikely but possible that all four compressor housing mounting screws came loose at the same time.
It's REALLY unlikely to be on the turbine side. I don't think it's possible for a vane to come loose.
I really really hope that the cast iron center housing didn't crack, but check for that if no other source of noise and oil.
puking oil onto the ground, from the front (bumperside) of the turbo, or oil feed line (or oil cooler). Zero oil going into the CAC. Also this thing has had full synthetic oil changes all its life, every 3000 MILES. Since owning it (i'm 3rd owner) I have used nothing but top tier HDEO full synthetic oil and synthetic media filters in it. No sludge, no buildup, you wipe away oil and the engine internals shine bright and clean.

Your turbo is shot and the amount of oil coming out of it proves this. Take it off now before it grenades. The squeal that you hear is the conpressor wheel rubbing the housing. Also our turbos spin at 64,000 rpms at idle, there max limit is 190,000.
10-4 on that......the shrieking/whistling at idle is low but quite audible, and increases with RPM's to the point that even inside the jeep with windows up its loud.
