Death of an Excursion
... I think my gasser 2000 Excursion may be done for, at about 115k on the odometer. Today I stopped at NAPA to check on cost and immediate availability of a new (not rebuilt) starter. For the f...

With what you describe, chances are that you haven't wiped out any bearings and such.
Even with low or no oil pressure for a short time, the engine was not under load. It was idling. Yeah anything will rattle if the oil pressure drops off. But it takes a while for the residual oil to go away.
Kind of odd that the pressure would go away just sitting there idling.
Now that it has sat a bit and the engine is cold, you could try firing it back up and see if you have pressure. Pick the revs up a bit, not much, but a bit, say 15 - 1800 or so for a few seconds and see if there is pressure there.
But really, if all you have done is lost a pickup or oil pump, that is a relatively cheap fix. A 2000 Ex is still a nice truck and it would be a shame to sell it cheap broken. You won't get anything for it with the engine down.
It takes a while for the engine to sustain major damage from no oil. Had a friend once who drained the oil out of a slant 6 and put a brick on the gas pedal. It sat at valve float with no oil for about ten minutes before it ran out of gas and quit.
You engine is likely fine inside. Pull the engine, drop the pan and check the oil pump and pickup. Really, thats the only thing that could cause no oil pressure. Could be the drive rod that runs the pump too. A blown main bearing can cause low pressure but not no pressure. Putting a pump in it will not cost that much compared to a whole new engine.
Even if you pull the engine, put it on a stand and pull the bottom end apart for inspection to mike the crank and plastigage the bearings for peace of mind, it is still a lot cheaper than a total new engine. Pull the main and rod caps off and look at the bearings. It will be obvious if they are pooched. If the bearings are good then the rest of the engine is likely ok too. Cam bearings will be as worn as the rods and mains.
In that short a time, the pistons, rings, cam, lifters etc. will most likely be unaffected. It's just a matter of figuring out why the oil pressure went away and correcting it.
And it is cheaper than replacing the truck.....
If it were mine, I'd fix it rather than looking at a new Jasper engine or FoMoCo long block.
