My new 347 has the LS6 pcv setup on it, and i'm wondering what difference that will make, and what i need to do with the pipe on the front of the valley cover. i'm running a breather tank with a fitting coming out of each valve cover into the breather tank, will i need to splice that small one from the valley into those also? thanks guys

...should answer most of your questions.

 

awesome info there, but it didn't cover one thing i was wondering.

i'm guessing running a -10 line from each valve cover into a breather tank will suffice for ventilation, but would it be fine to just cap off the little fitting on the valley cover or should that be vented to something also?

 

So, did you totally eliminate the PCV valve?..if yes, then cap it, if no, then run a PCV hose from the valley cover to the manifold like the link had

 

From valley cover to intake manifold. If no PCV then cap it like ditmeion said.

What I'm wondering, is it ok to have a PCV and breathers at the same time? Unless the Breather is a one way vent, how would you draw a vacuum from the PCV system? I would think you want one or the other.

Either, or, but not both.
Breathers>cap PCV or run PCV (Valley cover to Intake with proper LS6 PCV Valve)

 

i'm gonna cap it and just run my breather setup like i had planned, thanks guys.
