Low oil pressure new engine Installed a NEW LS1 manufactured late 1998 and in crate til last week in my dads 99 C5.Can't keep oil pressure up at idle and only 30-40 psi at 1500-2000 rpm.
Is it possible for the pressure relief valve to be hung open from the factory and oil is by passing into the pan? Any thoughts would be appreciated.Three weeks without his car and I caught him looking at new Mustangs.aghhh

We had to switch the pickup tube and the pan and I did not realize there was a o ring that was left in the pump. I believe it should be on the tube during assembly and I think we are sucking air and not allowing the pump to pull properly. Does this sound right? Thanks for the help.
