Oil pressure is higher after oil change

You may want to move your pressure gauge to the 1/8 BSP port on the engine block.

The engine oil pressure inside the engine = 35psi - (oil cooler & lines pressure drop) - (oil filter pressure drop)

If my engine is "normal" it seems like your oil pump needs an extra 10-15 psi to push the oil through your oil cooler and filter @ 180F

With that in mind, if your actual engine oil pressure is 10 psi due to a failing galley gasket, your gauge might show 20-25 PSI, which hides the problem and may result in a spun bearing / new engine... and no one wants that!

I do plan to eventually relocate the sensor to tee off the oil return line to the block. But for now I’m not concerned that it’s giving me a false reading. Pressure drop in the filter should be 1-2 psi and in the cooler probably about the same at idle. Therefore I think anything over 30 for a pressure reading is totally normal.

But to your point… reading pressure after the cooler and filter would giving me the reading that really matters… what’s going into the engine.
