I am trying to figure out a prob with a car that is making no oil pressure after an engine rebuild (stock). Bearing clearances are good for sure and engine has new cam bearings. New GM oil pump and pickup and oil pan. I installed a freeze plug and 3 plugs for the oil galley on the back of the block. Are there any on the front of the block as well? Would they make the car have no pressure? I don't remember seeing any as I built the motor but I could be wrong...

Oil pressure stays at about 10-15 psi and NO oil gets to the valvetrain. I let it run for a little bit, pulled the valve cover and the driver's side was dry, passenger side barely had any...

Anybody?

There are 3 plugs in the front of the block right above the camshafts journal. There is also a plug in the block beneathe the rear main cap. Has a hole that appears to go nowhere, but a plug is at the bottom.
