The road draft tube pulls air out of the crankase & fresh air enters through the valve cover. 1963 & later used a PCV valve instead of the tube & 1968 up used a tube to the air cleaner instead of a vent on the valve cover.

Make shure your roadraft tube is not pluged up. There might be a latter model cover that uses a vented oil cap instead of the slots.

On another subject, I've installed a primary fuel filter just under the gas tank because a lot of rust was working its way up through the fuel system. This truck has been fitted with an electric (6V) fuel pump, and it had one of those cheapo in-line filters downstream from the pump. I got tired of stopping and flushing everything on the side of the road (at three bucks a gallon). so now I have the two glass inline filters - so I can see what's in 'em, though I'll have to shield the lower one to keep a stray rock from radically affecting my fuel economy (which already ain't nothing to brag about) - and I've bypassed the fuel line from the tank to the carb. that's where the blockages were happening. A temporary fix, but the lines are all tied neatly and safe. On my old truck I had a filter right beside the carb, and it had a removeable glass sediment bowl. I'd like to see another of those one day once most of the crud has worked its way out of the tank.
