Re: 1939 super 8 oil pressure

My repair manual only goes back to 1940 but it says a Super 8 should have 50 PSI @ 30 MPH. Naturally it will be lower at idle especially hot. I would expect 15 or 20 PSI at idle on a rebuilt motor.

Try a good mechanical oil pressure gauge if you want to be sure. Your gauge may not be quite accurate after all these years.
