Poor oil pressure
Ive got a 1990 2 door montero that has really low oil pressure when idling after being fully warmed up almost to 0lbs. When driving however it it will bump up to around 30lbs. Anyone have any ideas? I was thinking maybe the oil pump but I was just wanting to make sure before i replace it.

Next, check the wiring. Have someone sit and monitor the gauge while you move the wiring from the sending unit. If the gauge "bounces around" it's mostly likely the wiring.
If both of those items aren't the problem, the pick up line could be clogged, or the screen on the pick up could also be clogged. Oil pumps are the only part of the system that run on unfiltered oil, so check the parts that feed the pump first. Finally, if nothing else helps you find the problem, replace the pump itself. It's the most expensive repair in the series, so I'd check everything else first.
Good Luck
