Is this ok for PCV?
Is this ok for PCV? I am running a Super Vic intake now on my truck and not exactly sure hat to do for PCV. Here is a drawing I put together and wondering if this might work.
I would be tapping the oil fill valve cover to run the same size lines off of it to pull equal from both valve covers. All 4 would would merge up to a single 5/8 going to a PCV then in to the catch can. Then a single 5/8 would go to the Dominator/4150 adapter plate.
I would be using the factory LS6 valley cover nipple to the same Dominator/4150 adapter and a 3/8 line.
Suggestions totally welcome.

What brand catch can are you running? Is it vented? Is this a carburetor application?
Here's a diagram of a fuel injected application I did for another member. Take a look and let the questions fly.

Any reason not to hook the Valley cover up to the air cleaner and use the 4 ports I show in my drawing?
Also, does it really need fresh air or any air for that matter? Wouldn't it be creating a vacum if sealed other than the catch can line?

Typically, the clean side of the PCV is connected to the valve cover and in front of carb or TB. The line on the valley cover is the dirty side. Don't mix the two unless he whole system is vented.
I guess I don't understand why the valley cover needs to be the dirty side vs the valve covers? Is there a specific reason for this? Just wanting to understand why.
It would seem that if there was any condensation build up from the enviroment (I live in a semi foggy area being close to the coast) you would elimate more of it via sucking it from the valve covers. But on the other hand, I could see less oil suckage pulling from the valley cover as it's in front and doesn't see as much oil as the rocker area.

The valley cover has a built-in chamber that attempts to slow PCV flow and separate carry over oil from the PCV stream. I can only assume it does allow for some oil separation so reversing the clean and dirty sides of the system would eliminate this functionality.
If you want to pull the dirty side from a valve cover than route it like the LS1 and cap the valley cover.
