I had the same problem with my 56 Patrician. It is a design flaw in the oil pump. You can try running with one quart over full. I did not have any luck with that solution, so I had the pump rebuilt by Bob Aller. That worked for a time but then the problem returned. I recently bought the OLDS pump conversion kit and had it installed. Oil pressure increased but I am now leaking oil out of the rear engine seal. Good luck with whatever fix you use.
