Default PCV Valve

I am looking for information for my 1946 F1 pickup.
I am wondering if there ever was a PCV valve installed in 1946.

The late model engine is the easy one to modify. Use a new filtered oil fill cap. Remove the intake manifold, and drill in to the bottom until you are in to both runners equally. Drill to 3/8 pipe size, then tap for same. Remove the pipe from the crank case, and shorten it by two inches, then make two angled cuts 2/3 through at an angle leading down. Weld, braze or silver solder light sheet metal in these cuts to act as baffles. Reinstall the pipe, with a 302 Mustang PCV and grommet, the grommet fits just right. Use a 3/8 90 degree brass fitting with a 3/8 hose barb in the intake manifold, then at assembly, connect the two with good quality hose. Reinstall the outside pipe to make it look stock, and you will have a PCV where nobody can see it.

To answer your question; As I recall the WWII military trucks that were equipped with fording accessories, ie; a closed crankcase, etc., for use in high water, had a PCV system a sealed ignition system and a snorkel on the intake that extended above the windshield frame.
I have a ex-miltary Dodge flat hear six that has a fording kit on it..

As far as your F-1 Pickup is concerned no PCV valve was used on the flathead V-8 engine. There's a vent on the oil pan that helps reduce crankcase pressure buildup.

This message is for Johnnydidd!! Back in 1963, in Miles City, Montana, I had the pleasure of owning and driving a 56 Merc Monterey just exactly like the one in your signup.. paid $125 for it and never had a problem with it. Loved it.

Blucar in post #6 above is sort of right.

In WW2 there were mercury 99a flatheads made with a closed crankcase ventilation system and these engines were used in vehicles that had the engines inside with the occupants like bren gun carriers, tanks, boats etc. My friend has one of these and they have a 1/2 inch tube on the inlet manifold running from the base of the fuel pump stand to the base of the carb stand so they recirculate the fumes.
I have a photo of it somewhere and if I can find it I'll post it.

Maybe your truck has one of these motors.

Canadian trucks and carriers got the PCV system. My info is from scattered hints in a bunch of different manuals, mostly from CMP trucks, and I have posted a bunch on them here.
PCV first appears in the 1943 edition of the truck manual, no way to tell how much earlier the hardware appeared, but certainly on the C29 engines. I've slowly gathered most of the bits, actual valve seems to same or similar to the USA jeeps.
I think the picture above is of the early version...my manifolds have that pickup hole left cast closed and a new port added into the right side of the manifold where it rises to mount the generator. The one shown uses the truck vacuum brake hole, a big 3/8 pipe hole that has two much smaller holes through into the two sides of manifold. The possibly later one inhales at front of manifold and gets its suction from a plate under carb that branches into the two sides of manifold with small holes, very much like the hookup used with Southwind heaters. It's also possible that the 2 arrangements were for trucks with and without power brakes, but I suspect they moved the port because there was too much oil being flung around at the back.
All the manifolds were Canadian 11A types which had casting provisions for several arrangements covering the several vacuum arrangements on current and earlier flatheads.

My war time pcv is set up like bruce discribes, plumbed at the front on the raise for the generator, directly above the breather stand pipe in the valve chamber. But the pipe travels around the back of the carb and into the large fitting like the pictured one above. Marked Donaldson Crankcase Ventilator.
This setup was on a 99A out of a Bren gun carrier I believe, it also had the full flow oil filter set up on the bell housing.

Thanks for compliment on my merc, its a beautiful car drives very well, has power steering, rebuilt automatic, rebuilt 312 with a set of pipes that will blow your windows out. I had 56 HT when I was young, it also had a set of pipes, I lived in a small town out in Kansas it had old buildings with large plate windows, I could drive through town with pipes screaming you could see the light reflecting of the windows as they vibrated.

When I was in high school, my best friend's older brother had a black on black '56 Mercury Monterey 2 door hardtop. We would always borrow that car when we double-dated to all of the "big dances" at school. Even in 1959-60, that was still the best looking, classiest car that anybody had, and most pf our friends parents had Buicks, Cadillacs, and stuff like that. (They were mostly 4 doors, however.)
