How do you know

After the issues with my sock filter, I wonder how to know if oil is circulating? Pressure gauge is busted. Easy enough to fix that. But how do you know? By the way.....it ain't leaking out canister or bolt any more. Made a gasket out of old tube for the bolt!

Those are partial flow filters, no you never really know.

With even 3psi of pressure, it will idle and run, no load, forever. Most fair to mediocre Farmalls carry 75 psi cold and 40 warmed up. Put a test gauge in the oil pressure port and see! Jim

if nothing else at least take the one out of your M and try that. pretty risky running an engine not knowing if it has oil pressure. it must have some pressure or it would be seized by now. plus you said the oil filter is leaking, so if it had no pressure the canister would be empty also . you can buy those gaskets for that bolt. i would not trust an old tube as it is not oil resistant and it will leak later, temporary fix.

This is how I would check:
Run it at idle for a while. Then take valve cover off. If plenty of oil, ok. If dry, you may have a problem.

Better replace the gauge so you know there's pressure to the engine bearings!

As to the filter, it's a "bypass filter", only a trickle of oil is supposed to be bled off of the oil pump's output, filtered, and dumped back in the crankcase. The typical figure that gets tossed about is 10% of the oil pump's output, but that's not closely controlled, it depends on the size of the orifice in the filter assembly and the oil viscosity and temperature,

Starting with a cool engine, if oil is being filtered the filter canister should warm up right along with the engine.

First, yes get a gauge on it so you know you have oil pressure. Wouldn?t be that concerning if you knew it
showed pressure before but then the gauge broke. Next time you have the filter off one of your Farmalls look at
the canister bolt. You will see a small hole somewhere along it about a 1/16? dia. That is the amount of oil that
flows through the filter. Mid 50s to early 60?s is when most manufacturers went to full flow oil filter systems. As
an example when Chevy came out with the small block in 55 it did not have a full flow filter system, in 56 most
all of them were equipped with it.
