Gerald, that's 100% bullpuckey!!!

Where did you get an idea like that???

The "N" Ford's oil pressure regulator valve, located at the front of the engine

dumps any excess oil into the timing gear area, where it returns to the crankcase.

The bypass filter is fed oil from the main oil gallery at the REAR of the engine, and a simple (tiny) oriface limits flow OUT of the filter canister, so that only a small amount of oil flows through the filter assembly, so as no to drop the engine's oil pressure too much.

AFAIK, ALL the 9N's, 2N's and 8N's would have had oil filters, from the factory.

Originally, the filtered oil was simply dumped into the crankcase. At some point, a change was made where the return oil from the filter was piped to the other side (RH) of the engine, where it was returned to the crankcase through the governor, lubing it on the way.
