CC engine oil pressure

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

I thought the "plunger" was part of the relief valve for the oil system.

I may be wrong, but I'm pretty sure the pressure regulator is in the plumbing right after the pump - brass thing with a big hex head cap with a ball and spring in it - at least that's what I figured it was..... I did similar to basil on mine as explained in his earlier post, but I only hit around 30-40 psi max on my pressure guage and have been told that that should be plenty so I've always assumed I was okay.....

Can I get to the oil pump and what is believed to be the pressure regulator through one of the bolt on panels on the sides of the engine? Also, does anyone know how much engine oil the CC holds? I would like to change the oil.
