Default oil pressure

so today when i was riding along i lost all oil pressure. I shut her down, and got a pull back home. I lost my turbo in the mess, and still have no oil pressure. any ideas as to what happened? there is plenty of oil, but i read something about priming the oiling system? could it be an oil pump?

Have you checked it with a mechanical gauge? Also by "lost the turbo" what do you mean?

just casting my vote for oilpump. and crfsti, Odds are the pickup would be blocked by a mangled oilpan before it actually cracked, any welds on them I have seen have been solid and the piping is nicely radiused.
