crankcase ventilation
Does anybody know why these vehicles were made with an unvented crankcase? Has anybody tried to install one?

Re: crankcase ventilation
crank case is vented to the air box (from oil filler base).

Re: crankcase ventilation
I saw that hose between the airbox above the carbs and the oiler filler tube. It threw me off a bit when I could not see the inner end of the hose nipple inside the oil tube but I finally figured that out.
I expected to find another house going to the intake manifold with a PCV valve. All my other engines had a way to circulate air through the crank case. Either a draft tube and breather cap or a PCV system. I have always been under the presumption that you needed to circulate air, not just provide a vent, to get the blow-by out of there or you would have trouble with water and fuel in the oil.
My old power wagons (46 to 49) had a tube between the valve cover on the side of the block and the intake manifold with a PCV valve and another tube between the air filter and the oil fill tube. I think most trucks back then had a draft tube but they put this setup on these trucks because it kept dirt and such out of the crank. If the PCV valve would carbon up you would get the white oil-in-water that you get on Pinzgauers.
