Keeping in mind the above was the system GM used based on the part technology back then.

I checked a 1962 cast iron body that I have, and there is most definitely a small hole drilled through the body and upper bushing so the oil has a pathway from the sawdust to the shaft. That makes complete sense. They could use the proper weight oil for the application and the sawdust meters the flow. The aluminum bodies that I have do not have the hole. D-R would not go to all the trouble of installing the oiled sawdust in that cavity if it was not doing anything. The oil must reach the shaft - I'm just curious what the path is.

I really don't want anyone to spend a lot of time on an answer - I'm currently building a mag-pulse distributor for my '63 project and I'm faced with how to lubricate it. I just get obsessed when I see something that doesn't seem logical.
