Low Oil Pressure After rebuild
2003 4.6l engine with 80k on it. Had a leaky head gasket (oil, not coolant) in rear of engine. Decided to tear everything down and rebuild the top end.
While I was there, decided to pull the sump and front cover off to check the pump and timing gears.
Both the oil pump and timing gears were cracked. I followed this by replacing everything.
So here I am, finished, car turns over, and bam. Low oil pressure light. Seems sluggish at idle but runs smooth at 2k rpm.
I KNOW, Need to do a pressure test, don't have the equipment yet, so planning on doing it.
Also, when assembling the oil pump, I did something stupid. I put "all purpose grease" on the gears with some oil hoping to prime it. I'm guessing that the grease is to thick and clogged the Relief Valve.
Spent a ton of hours on this project and it sucks I can't run it. But I would rather do it right then ruin everything
Thoughts and opinions are welcome. thinking of taking it to a shop just so I don't have to pull that damn oil sump again

if the grease were petroleum based i would say no problem, as oil is also petroleum based; which is way they say to use petroleum jelly.
you might try removing the oil pressure switch, pull the coil or fuel pump fuse, your choice , crank it and see if you are getting oil as far as the switch.
