Truck oil pan ?
 

1 Attachment(s)
Ran across this pan with removable lower flywheel section but noted it has no oil breather. Cant figure out its intended use.., i know 32-35 never had a removable rear section or oil filter return. Ideas?

The 1948 and earlier Ford flathead V-8 oil pan with the removable lower section was used on commercial vehicle's.
The idea being a truck or bus would wear out a clutch a lot faster than a car. So making it easy to remove that rear lower section of the pan made a clutch and flywheel removal a lot easier than pulling the entire oil pan. Some of the larger trucks and buses were an open drive type transmission so the tranny removal was easier as well. No toque tube rear or an engine to pull to get the transmission out.

Ronnieroadster, do you have any thoughts about the lack of the normal breather exit?
I've never seen a post 35 pan without the breather

Did military use a PCV system?

Looks like the main pan stamping and the doubler brace had room for the breather. The worker must have sneezed when that pan went down the assembly line.

Yes, and my guess is this is a military pan.

Most trapdoor pans were for the big 4-speed clutch. V8s were used in the universal carriers in both 221 and 239 types and they had to have a PCV and oil coolers due to placement in the middle of the carriage. Some big trucks also had PCV in Canada. I'm not sure about US manufacture.

Maybe he's not done cleaning it up... the thread wasn't titled " how's my sandblasting job?" It's a dam sight cleaner than mine will ever be.
