Couple of thoughts.

Bought a non-running tractor one time for a non-running price thank goodness. Got it home and got it spinning (not running, just spinning). No oil pressure. Checked for clogs....none. Checked the engine bearings found reason... very bad mains.
You could have a clog or you could have a worn out engine.

Several places to look

Remove the plugs or injectors, whichever.

If it has an oil filter remove it. Spin the engine with the starter and oil should run out the filter hole. If so the pump is working. Put it back.

Pull the valve cover and spin the engine for awhile to get oil to the valve train...the last thing to get lubed in the oil delivery chain. Got it good. No then engine bearings could be worn out (mains, rod inserts, cam).

If you had it you have a clog to your/in your gauge or a bad gauge. Just back up the line and find it. If you get back to the block a piece of baling wire may clear the hole. Leave the port open and spin the engine and see if it will/can pump oil out the hole.

Set your air compressor to 30 psig and shoot air into the gauge. Does it measure 30 psig?

On the blowby, it is common on engines having wear. The wear doesn't have to be severe and the engine can run for a very long time after it develops blowby. If everything is ok and you aren't burning oil at an unbearable rate don't worry about it.

If you had a vent pipe, like 3/4" in dia (Ford and JD have em) you could put a piece of garden hose over it and route it to your intake manifold with a hose barb and run it back thru the engine. That's what today's PCV systems do on auto's.
