yes bargy, the pcv goes in the line from the rear base of the carb to the road draft opening [a fitting replacing the tube] and that sucks the fumes from the crankcase, but there should be a regular vented cap on the oil filler so there's someplace for air into the block - skip the tube from the oil fill to the air cleaner, you do not want to be creating a vacuum in the lifter gallery and oil pan
picture of the pcv part - don't know how that original setup will get by inspectors in Calif .... the tube from the valve cover would have been the one into the air cleaner
