Both great points, I definitely will run the borescope soon to see what it yields.

I guess my biggest question right now is: If I repair the gallery gaskets on the current motor, what are the odds it will it run for maybe 40-50k without catastrophic failure?

If there's no point in repairing, a replacement motor seems logical from the get go. But the oil analysis results lead me to believe if the pressure issue is solved, the motor may still have some life left in it.

I am also pretty sure I know exactly which short drive the metal flaking resulted from, and it was right before I changed the oil and discovered it. I don't believe the engine ran for an extended period of time after the gaskets blew, but there's really no real way to tell given the obvious wear that has occurred.
