You think the air is flowing the same direction in both hoses. Its NOT. It flows AWAY from the TB and INTO the valve cover. Oil mist is not traveling against the flow of air. Once the air goes through the engine it comes out of the valley cover and into the INTAKE neck. Ya see? It makes a big loop. Thats why the catchcan is built into the valley cover, to catch the oil mist before it gets dumped into the intake.

Well I don't know about the specific PCV valve on the newer set-up but obviously a PCV prevents backflow down that particular hose that its installed on.
170$ ?? i got mine from scoggins for waaaaay less......the previous style used a pcv in the hose to the intake.......the preforations in the new style act as a catch can within the valley cover.......so no need for a external pcv...........still not sure on which way air flows in the hoses.......previous to the LS6 vc install .........oil mist (gunk) accumulated in the TB from the valve cover hose which indicate that air flowed into the TB......have not looked at the TB since the install of the LS6 vc
here's another pic to help your cause 01ssreda4, I'm with you bud
This is how mine is setup on my LS2, but its the same as the LS1/6 with the LS6 valley cover. For a LS1 you just need to block off the rear fittings.

Yes you can block off your two rear connections, HOWEVER, I think I'm going to run one single line between the two and connect them. Is this needed? Probably not. Will it hurt? Probably not. And actually I would think cutting one piece of hose would be simpler and quicker then blocking the ports off.
