Re: Oil pan/babbiting question
Float valve in one or both carburetors is not seating tightly. With a full tank, if the fuel is not shut off, the carb will overfill and fuel will leak down the throat and into a cylinder, down past the rings and into the pan.
I have seen two cases of this very same thing recently. One was with two Stromberg carbs and one was with a new Weber.
If the carbs are Stromberg's, they are notorious about the float valves not completely sealing and the carbs overfilling and running over.
This is one reason I have up-drafts on all of my Model A's.
Shutting off the fuel when the engine is not running will prevent this from happening.
Change the oil and if it runs and sounds OK, run it. Chances are it will be fine.
My experience and opinion,
