    Losing Oil Pressure

    When I start it up it looks to have about 50psi on the gauge then after about 30 seconds the check gauges light come on and it drops to 0.

    I would recommend hooking up a mechanical gauge to the top of the oil filter housing first to see if your factory dash gauge is correct. You could have a bad sender, gauge or wiring issue.

    Did the oil pressure come up to 50psi then after 30 seconds drop to 0psi when viewed on the mechanical gauge plugged into the top of the oil filter housing?

    If this is the case don’t run the engine. Sounds like something is plugged up or you have a bad oil pump. Hopefully others will chime in.

    I have seen the oil galley plug behind the cam gear not reinstalled after being rebuilt a few times now does exactly what yours is doing has oil pressure for 30 seconds then drops to zero.
