I think they first started using the PCV valves in WW11 on tanks for going under water while fording a river. The crankcase was plumbed to the air cleaner which was ported to a snorkel above water.

Those PCV valves were common on many engines. They are "take a part" for cleaning and didn't need to be replaced. Dunk them in a carb clean tank and you were good to go until the next "tune up".

The old 4 cylinder Jeeps had that same PVC check valve,, years before they were mandated by Uncle Sam.

Tony, I hope to have the C2 here by next week sometime.

It must be a Hercules thing, my '47 Federal w/a JXB has the same sort of check valve off the tappet cover, and a 'cute' little oil bath cleaner off the oil fill tube.

Stretch (7/7/2016)
Is that an oil bath crankcase breather ?
Looks to me like that engine was a runner before it was layed up.


I think you are kinda right Stretch. But it must be a coalescing filter to separate water and oil vapor vented from the crankcase. The water and oil must settle to the bottom and have to be dumped when full.
