Ok, long story short, a guy traded motors and had it dissasembled/cleaned. He then put it back together with new bearings. Motor has no oil pressure. Brings it to me, i figure out he reused the oil pick up o ring and put a new one on. No dice. So i pull the filter and it shoots oil out, so oil is definatly getting that far.
It's not a bad oil pressure sensor, the sensor is bone dry.
So where does the oil go to after the filter? Anyone have a detailed schematic? I'm hoping there is an oil plug somewhere that got left out, cause i don't feel like pullin this motor out.
So far i have verified that the front oil plug (drivers side next to pump) is there and so is the oil diverter (barbell looking plug) is there too.
Any ideas?

So I apologize to everyone if my answer is not close and I'm way off target, but here goes nothing.
I had the same problem with oil not getting to the top of the motor, until I looked closely at the oil diagram for a 5.3 gen 3 vortec, the two ports above the oil filter, are there for a engine oil cooler, and on a 5.3 L Gen 3 motor, the two ports can not be blocked off, one of the two ports sends oil to the top of the motor, so it needs a bypass adapter, not a blocking plate, if the plate is installed. Oil cannot be sent to the top of the engine.
