Is that pressure reading hot or cold? I'm going through a 1941 160 that i bought recently with a mysterious past. The pressure is above 40 lbs cold, but falls significantly below that after abut 1/2 hour of driving. I'm starting the investigation....

John, connecting into the oil pressure gauge/hydraulic lifter/oil filter fitting with a mechanical gauge I had a reading of 40 lbs with a warmed-up engine at idle speed. Move the speed to fast idle and it went to 45 lbs. My other oil pressure gauge (Stewart Warner mechanical) that is connected to the last tap on the main oil gallery reads a bit lower. It shows no more than 40 lbs at running speed and temp and down to 20 lbs at idle. There seems to be a difference between what pressure is available for the hydraulic lifters and for the main bearings. I would appreciate it if you would share your findings with us. Thanks.
