Did water make it into the engine block?
If you took the pump out of the circuit and it held, then the pump could be leaking. You could remove the pump and unclamp the hoses and watch it leak....or not.
Does the cooler feed hose isolate the cooler? I have a different set up, so I'm unsure of your cooler's routing.

Below is how the cooler is fed on my bike. Based on what I'm seeing I think the next thing to check is the oil cooler seals, after that a compression test to see about the head gasket.

Hopefully the cooler seals are gone. Anything else is major repair.
The compression test will only show anything if it's leaking into the combustion chamber. That will usually result in a misfire and rough running. With water pouring out like it is, it's probably not in there, as the rings would hold most of it. The only way the head could be at fault would be if it's blown out majorly between the coolant jacket and oil return. With the metal gasket that's in there, that would be pretty hard to do. You hope there isn't casting damage somewhere in the engine block.

Got the oil cooler back on tonight, poured nearly half a gallon of water in to the radiator before it started coming out the oil pan drain. I'm sourcing parts to build a leak down test rig, probably do a compression test tomorrow. Not looking good at this point, but I'm in no rush and want to learn. So as long as I don't have to sink too much into it I plan to continue with this thing.
