Ka24det no oil pressure

[6berry]

So i was driving home on a bumpy road after a day of drifting. and suddenly i hit a big bump and i start to hear a valve tick. i get to my shop, pull the turbo oil feed and nothing. (no oil pressure gauge) i assume oil pump so i pull it all apart, find that my oil pump is fine besides some slight scoring. i then assumed oil filter got clogged because it was bone dry. i put a new oil pump in, new oil, oil filter, etc.
i started it today and still no oil pressure. i can pull the oil filter off and absolutely nothing comes out.
does anyone have any idea what the issue could be before i tear it all apart again?

Safe to assume you checked the oil pickup since you pulled and inspected the oil pump?

Forgot to mention. Yes the oil pickup was inspected and appeared relatively clean then I sprayed it with brake clean as well

Did you replace the gasket? Can't remember if KAs have a paper gasket or an O-ring for the oil pick up. If the pick up is good, everything points to a bad oil pump.
