Oil Pressure drop

[Lonestar10]

I would just get a decent 50 or 100psi gauge with a hose on it that you could then adapt to either the orb fitting the sensor is in or to a plug that can be removed by oil filter. Or just try another sensor and see if pressures are the same. For me if I had a spare sensor I would just put it in and check pressures at idle and revved up. But if readings are still low it's not healthy for cam, rod, mains as Cummins already runs to low in my book compared to a Detroit running 55-60psi
