If it has an electrical sending/sensor that could be the problem and the pressure is probably in fact just fine. If it is mechanical ie: Oil pressure line goes right to the gauge then double check it with another gauge. Electrical oil pressure sending units always low ball on their way to davy jones.

Perkind 4236 low oil pressure
Good old Perkins starts showing low pressure (<10PSI) after a couple of hours. So I replaced oil pump and took to it 0.30 (crankshaft) but problem remains. Any ideas? Refilling check valve? Is it the gauge?
Manuals show counter balances together and were dot alligned as indicated although that is counter intuitive because one could balance the other and have less vibration and less wear.
