WW2 Ford Canada Military Engines- PCV system

[fordblitz]

Good Day,

Responding to a PM, but I could not post photos there so here is the setup used on Ford Canada Flathead V8's for positive crankcase ventilation on military vehicle engines:

System consists of a PCV valve fed from a tapped hole at the front of the intake manifold above the gallery. A standard SAE flare fitting and 1/4" Bundy tube is used there.
One setup, as shown in the diagram and bottom photo, uses a spectacle flange below the carby that allows the PCV valve to draw a suction from inside the gallery at the front of the intake manifold.
Another type shown on the photo of the manifold has fittings at the rear of the carby stand to draw the suction. Both use an oil bath air filter on the fuel pump stand to filter the air going into the crankcase.

The spectacle piece is hard to find even in Australia. I think many were discarded in post war use. They were a die-casting also prone to corrosion. The PCV valve however I have been told is the same as used on wartime Jeeps but I cannot confirm that. The plumbing is straightforward 1/4" tubing and fittings.

Hope this is of some interest and answers a very late to respond question.

Cheers,
