It's me again. I removed the engine oil pressure pop out plunger assembly and installed a 6" pipe down through the plunger casting and hooked up an oil pressure gauge. It works really well. When I started the engine the gauge pegged out at 85 PSI. Thinking I bought a bad gauge, I installed another new gauge with a higher reading. It pegged out at over 100 PSI. Does anyone have a clue as to why my oil pressure would be so high? What is the correct pressure reading? I would think with a 79 year old engine the oil pressure would be low. Also how does one adjust the oil pressure pump? Thanks, Basil
