flatjack, your right, thats the way the originals worked, and it let the fumes out under the car at idle, but when you hook up a pcv with the original draft tube the air is pulled in thru it, the best way is to plug the vent tube and use a pcv valve off the carb or manifold with a vented oil cap, modern engines use 2, one for each valve cover, one from the manifold and one coming from the air cleaner and using a vented oil cap
