I have a 1953 Ford Golden Jubilee. I had the motor rebuilt buy a "profesional" shop. But, ever since the oil preasure has been lower then it should be. 30lbs when cold at say 2000 rpms. Thens it drops as the engine gets warm. They installed a brand new oil pump when it was rebuilt. Being as it's been a couple years since it was rebuilt, I decided to pull the oil pan and look at the oil pump preasure releif valve, and the preassure tube rubber gasket. Well, as soon as I pulled the pan I saw the problem! They put the rubber gasket on the preasure tube, BUT failed to screw the nut on that squeezes the rubber gasket tight to the tube. Every thing else looks good, and I don't use the tractor much, so hopefully no damage. Now, I'm having a problem finding the round rubber gasket that goes around the preassure tube. I also need a preassure tube to oil pump gasket (wich I can make if needed), and oil pan gasket (and I have found those). I'm trying to find one supplier to buy it all from, so I'm not paying three different places shipping. Any help/suggestions appreciated.
