I ended up removing the entire oil filter assembly and running the test.
Cold: 30 PSI, still tapping Warm: 10 PSI, still tapping

Apologize for the sideways pictures, not sure why that happened.

One more picture. Looks like oil in the exhaust.

Are you using fitting wrenches? They are a special wrench used for working on tubing connections. Essentially a six sided wrench with a slot cut out to allow the wrench to fit over the tubing. They provide more grip than an open ended wrench. Strongly suggested for working on tubing.

Oh brilliant! I'll have to pick up a set of those. Didn't know such a thing existed. This time I was able to use a bit more elbow grease to get it undone and run the test.
Any input on the results of the test of ~30 PSI cold and ~10 PSI warm. From what I've been able to read it's too low. Even revving it up to driving speed it barely hit 40 PSI.

I recently removed and reinstalled my oil filler tube and did so at the incorrect orientation and had the same noise. Not sure if the design of yours is the same as my 51

Thanks for the suggestion.
I'm wondering if this means my engine needs to be torn down and if so if I should attempt to rebuild it myself or just farm it out.

Typical rule of thumb on oil pressure is 10 psi per 1,000 rpm.
So 10 psi at idle is fine. 40 psi at 2500-3000 rpm is fine. The last Packard engine I did was a 56 with all new parts and an NOS oil pump. It had 55 psi on the road and around 10 psi at idle using 10w-30 oil. The black exhaust is either rich mixture or poor ignition. Either makes for dirty oil and those motors are not very clean so there may dirt floating around. Leaking rings will show up as blue smoke during hard acceleration. Oil leaking via valve guides and seals is indicated by blue smoke at idle especially after starting or standing idle. Another possibility is worn guides and sticking valves. Worn guides will show up as a motor running better when squirting light oil down the carburetor while running, and sticking valves as quiet valves while spraying Gumout down the carburetor.
