All I had in mind when I made my comment was a way to visualize, or get some idea, of how much air is passing or could be passing through an engine. So, can you imagine 6.75 cu ft of air passing through a crankcase every second? I'm thinking, that's a gale force wind! Also thinking there's no way a pcv tube with what- .3" typical i.d.- can flow anything but a very small percentage of that.

It would be like feeding the exhaust pipe into the crankcase, no?
