I assume you say this because the gauge shows low? or are you hearing engine noises like lifter clatter? If it is a gauge issue I would start by replacing the sender or rolling in a mechanical gauge. Some causes for low oil pressure is plugged oil pick up screen bad oil pump and internal oil galley plug has fallen oil or excessive clearance in the rod and crankshaft bearings.

Please let us know what you find. We are interested to see what it is.

Cheers, Ken
