Thanks man, you are the man. LOL I thought I'd try Advanced today anyway .....three strikes and they're OUT lol. None of them had ever heard of a one way check valve and each of them insisted that it's already built into the PCV (kind of true but it's just not effective enough for boost ...I found that out just blowing into it). They didn't have any type of valve cover breather that would work, even with their breather adaptors in stock. They didn't have a plug that would work to replace the pipe threaded part on the ductwork. Three strikes and 45 minutes of my time killed lol, my dumb fault for even thinking about it. I got a plug from a hardware store. I'll find a breather somewhere else. Thanks for the PN.

take a look at that.. its one one of the local guys did around here back when he had a PD

 

Thanks but I found a breather. If oil is being sucked through that line and into the sc ductwork it is not working as originally designed anyway (flow should be in the other direction per PCV valve induced vacuum). I also thought about that hot air being sucked into the ductwork on this non-intercooled setup

I got an inline check valve too. After careful observation of the PCV valve I'd say it can definitely leak a small amount boost into the crankcase without the valve.
