mine on '68 barracuda has right side in place with connecting hose from carb to pcv valve on valve cover, but on the driver side the air cleaner is not attached with a hose to the oil filler cap (which is not the type with a nipple on it anyway). Does this matter at all; does it make any sense for one side to be in place without the other? It is supposed to be a closed system but if you are not concerned with legal issues/pollution, does this affect performance or anything else on way or the other. I'm liking the air cleaner nipple open to suck a bit more useful air. comments appreciated. thnx.
