05 no low pressure oil issue

05 6.0 came in with a blown up turbo replaced turbo truck ran for 15 min or so dropped lpo the quit running.its full of oil,lpop was grooved so its been replaced,stc is new,hpop is new,oil rail plugs and standpipe's are the updated one's.lpo regulator looks fine and the check valves in the filter bowl look good.it has no oil at all at the check port on the oil cooler.anyone have any ideas this one has me stumped.

If you depress the anti-drainback valve, and have someone else crank it. Does it fill up, and how fast if it does.

Do you mean the gears were grooved? It could've honed the housing out, harming the oil suction from the pan. Venturi effect?

over full the crankcase to cancle out a blow o-ring on pickup tube

it will no fill the bowl period not a drop,we filled it about a gallon over full still had nothin

Front cover is toasted maybe?

Thats what I was guessing.

any unusual thumping through the intake while cranking? Possibly lost a lifter
