May be of no use to anyone, but I lost oil pressure one day when I was warming up the juggernaut, shut it down, popped the hood. Oil everywhere! The copper tube for the oil pressure gauge broke (I guess I had accidentally crimped it) and I sprayed 2.5 quarts of oil out a small hole under 50-60 lbs. pressure. Quite a mess.
No ill effects on the engine. I suspect you caught the problem before any damage was done, but I like the idea of spinning the oil pump to see if the right areas get wet.
The lesson here, I guess, is watch your gauges, they're there for a reason. :p
