Small vid about PCV

Newbomb Turk said

Not like that. It’s like AJ said. With a breather open to manifold vacuum when it drops at WOT any blow by will go right into the engine. The OE’s didn’t do that.

They have a breather that’s open to atmosphere so at WOT the blow by can go somewhere other than the engine.

IMO, the guy who made the video should have just blocked off the open breather all together and just let the PCV pull a vacuum in the crank case.

Either you are wrong or did not word this well. The system as pictured differs only in one way from some of the cars I've owned--My 69 383 RR for example, had the hose from the air filter bonnet to the breather, was on the DIRTY side of the filter. I don't even remember anymore, if the 6BBL 70 was on the clean side or the dirty side. The method pictured, is essentially how all OEMs were done for years
