Oil Pressure issues.... Before I get the usual, "just do a search"...I did. I'm at a loss for options. I need a second set of eyes per-say. Here is the deal.
Stock bottom end 6 liter. ZERO oil pressure, not even a little bit, even after priming the pump, and cranking without coil packs plugged in.
-New GM LS6 oil pump
-Barbell is installed correctly in the rear
-O-ring is new at the pump
-I used an LS pick-up, and pan (clearance shouldn't be an issue).
-Bypass valve in the pump is closed
-Pulled the front cover off. Pulled the plate off the pump, its full of oil.
-Pulled the valve cover on the drivers side, bone dry.
What is left to look at? I'm stuck and frustrated!

I had a simular problem that turned out to be the O-ring on the pick up tube, I had installed a new one but it still was leaking air. What I have done sence then is use a little hi temp rtv around the pickup tube, just a little and put it above the o-ring so that no rtv goes into the oil pump it just seals the rib on the pickup tube to the edge of the pump. I still used a o ring with the rtv, It has worked great on 2 of my engines now!
If that dosen't work mesure the clearance between the pickup and the pan!!
Best of Luck to you!!
