Thanks! I started off by cleaning out the back of the gauge, then tested it with air. It was right on the money. Reassembled it and ran the motor and the pressure looks good now. It's actually showing slightly higher pressure than before across the board. I think the relief valve was stuck in place, it took a bit of wiggling and turning it inside the get it out. Cleaned up that assembly and replaced it was as well (without the nut). Always pleased when the simple solution in the correct one. I'll sure be watching the pressure closely as I continue to wake the truck up.

Working on my new to me 53 B-4-B truck. I removed the pressure valve and found that someone had added a bolt behind the cap, to increase spring pressure. What would be the reasoning behind this? I haven't run it yet to see what difference it makes in indicated oil pressure. I've only been able to drive the truck a couple of times so far. The oil pressure was great, then suddenly dropped across the board. Still not sure if it has actually dropped or the gauge is acting up. I had soaked the cylinders with Marvel Mystery Oil to see if I could lessen some smoking. Not sure if I stirred up some sludge and plugged something up or not.
