The "Early TImes Chapter" of POCI is focused on 1926-54 Pontiacs.
LOTS of knowledge and helpful folks in that group.
Here's a link to the chapter website:

The problem is their web site does not give any detailed information on this unique oil filtration system.

Yep, good point.
It's a good place to find contacts but not much of a technical resource.

There are only two references to oil "filtration" in the 1933 Chassis Service Manual.
Here are pics of those 2 pages.

The first reference is in the Oil Pan Assembly section:


And this, from the Engine Lubrication section.
The left column describes the oil pump and filter/screen function:



"Oil pressure may read zero with the engine idling but should show pressure with the throttle open slightly."


I have not touched the straight 8 in my 33 yet, so I can't offer any hands-on info.

In 1941 the filter was redesigned.
