Sounds like you may be tearing it apart in the future. Is it still under warranty? If so take it back. Or you could just buy a new one. Looks like you got some decisions to make.

If not under warranty (exchange it), pull the head first. If nothing to see there, drain the case and pull the sidecover.
BIG NOTE: Have the correct gaskets in hand before doing either one of those things! Inexpensive, even if you find the motor's trashed. If you have to get a new hemi 212, it's a comfort to be keeping those gaskets handy.

loud shearing noise
Been pondering that kind of noise, and in the absence of any visible major mechanical defects, and with good compression................
Could it be a coincidence that it died and won't restart? Did it suddenly rev up when the noise was heard, before you could back off the throttle? Sounds like a metallic mechanical issue, so while the clutch isn't related to the motor running, have you taken it apart for inspection?
