Let's see your LS1 PVC systems
TGO,
I'm just about done with my LS1 swap and am contemplating what to do about the PVC system.
- I really don't want to delete it and just run the breather
- I can't run the LS6 valley cover
All the swaps I've seen locally have the PVC setup with no catch can... Is this needed?
Can I see some of your setups?

Why I argue for duals, but a street car can get by with single.

Move the PVC to the drivers valve cover and run it like the diagram. Inline valves gum up quicker than traditional vertical valves. If you notice excessive oil consumption between oil changes, swap the PVC for a fixed orifice tube from a newer truck

I'm currently cleaning up the motor... I was just going to leave the PVC as is with the connections on each Valve cover ending at the intake manifold.
I have the LS6 intake.

Re: Let's see your LS1 PVC systems
Yes, closed system with can:
Your PCV system should be closed. Do not use a breather on the catch can or valve cover as it allows for unmetered air to enter the engine and makes the PCV system function improperly and less efficiently.
The intent of the PCV system is to reduce crankcase pressure manifested from blow-by during the engine cycle. Engine vacuum is much more efficient at drawing these gases out of the crankcase than venting to atmosphere. This also creates a small vacuum on the crankcase that does slightly improve ring seal and power output. The final benefit is the environment. A closed PCV system recirculates the blow-by gases rather than releasing them in the atmosphere.
Concerning the construction of catch cans; the internal construction is critical. If the can is empty, it's not doing anything to catch the vaporized fluids from the crankcase. In fact, there are very few catch cans with an effective internal design to function properly. Check out this link: http://www.saikoumichi.com/OCC_explanation.htm This is how an effective catch can is designed internally.
