ANSWER: If the oil pressure is too high, the most probable cause is a sticking oil pressure regulator valve in either the oil pump or oil passages. Please refresh my memory with the year and make and engine of this car.

QUESTION: Hello Brad how would you approach the problem with this 1940 Plymouth up-10 sedan can you tell me where the lines connect and where the vacuum would connect typically

Answer
The case of the oil filters blowing up and leaking sure sounds like high oil pressure and a stuck oil pressure relief valve or as Plymouth called it Oil Pressure regulator. It is on the left side of the engine low down and is a spring loaded plunger inside the block under a large headed hex valve cap. Remove the plunger and make sure that it slides freely in its bore and that the spring is not damaged. A stuck plunger can increase oil pressure and case what you are talking about.
There is one important vacuum connection that is located on the throttle body part of the carburetor just above the throttle plates and runs to the vacuum advance on the distributor. There are two oil lines on the oil filter. the top one runs to a plug on the side of the engine in the main oil galley. The bottom one runs to a port on the block lower down and drains the oil back into the oil pan. This is a bypass filter that only filters a small percentage of the oil.
The windshield wipers on your car should be electric and there would be no vacuum connection for them. Any other vacuum connection would be after market accessories like windshield washers and I have no information on them.
