Distributor Question.

Agree. I think the shaft gets lubed from the engine below. Some Mopar distributors have a tiny flip-up oil cap on the side of the housing. I recall just on my 383 big block. I use 3M oil. There is also a felt pad inside the shaft under the rotor that you need to wet with oil. You don't state your engine and there are at least 3 distributor types.
