Is my catch can plumbed correctly?
Hi guys,
I am having trouble with the idle of my new engine build, and I am starting to wonder if I plumbed the catch can wrong and have affected my metered air in such a way as to make my idle bad.
Engine is hard to cold start then when it does fire up it revs high for a few seconds before it slowly comes down. If I rev the engine in open loop it will rev then stall.
Please see the picture below.
I have one line coming from the passengers side valve cover through a PCV valve to the inlet of the catch can.
Then out of the catch can and into the intake manifold after the TB.
One stand alone hose from the TB to the drivers side valve cover.

Did that, just looking for confirmation my plumbing is OK? There are a lot of different ways to skin this cat. Main thing I am trying to confirm is that one PCV valve in the passengers valve cover is the only check valve I need in the system.

Thanks Chris, I think I am pretty clear on the way the PCV system is supposed to work. I read many of the catch can threads months ago when I originaly plumbed the can. I am really just second guessing my original plumbing as I am having some trouble with the engine stalling after opening the throttle. After some other discussion I believe this is more in the tune than anything else.

I get the idea for people to do research on their own. What I dont understand is why cant anyone just answer a question without being kind of a dick about it. There seems to be any number of people just waiting to respond with the old "use the search" or "read the sticky" If someone doesnt understand what they are looking at why not just answer the question?
