There has to be points for crankcase venting to work. Your set up there is really only one. In the original set up for an early 265/283/327 the hole back by the distributor is where the "road draft tube" would go and on the later PCV vehicles it would have an oil seperator that had a hose run to the air cleaner. The PCV valve screwed into the oil fill tube on the front with a non-vented oil cap. Look at the way the later valve cover systems work, one side is fresh air pull from the air cleaner (or filter air) and the other side is has the PCV valve placed in the valve cover and the hose attached to a full manifold vacuum source. You need a place for filter air to replace the fumes being pulled by the PCV system or your going to have oil leak problems in after awhile.
