Thanks Aaron I'll try that too.
My intended use is street and track day driving. I look the look of the ME Wagner PCV but it is quite pricey. I think I might try a standard PCV first. Do you happen to have any part numbers for an LS6 one? I see in an earlier post you mentioned to somebody about removing the orifice in the LS6 valley cover. Is this to create more flow?
Just wanted to check I'm not completely misunderstanding the above, shouldn't the flow go from the inlet pipe to the rocker cover (green line)?

I'm not aware of a removable orifice in the LS6 valley cover. The LS7 has a fixed orifice in the valley cover.
I did have the arrow and date incorrect on that drawing. Here is the corrected drawing.

Also, I don't know if it's my browser but I'm seeing alot of references to diagrams but the diagrams aren't showing.

Posts 188 and 191 were for a LS2 valley cover which does have fixed orifice PCV valve built in.
I had many diagrams hosted from an old web hosting account that I no longer have. All of those diagrams are missing because the host is gone. It was prior to this site hosting attachments like it does now. If you need a diagram or have a question, post or email; I'm happy to help.

Recently upgraded to LS6 valley cover but it’s the older style one that doesn’t have a PCV built in. With the way my catch can mounts, there’s not much room to put the PCV valve on the catch can inlet and it fits better going between the outlet of the catch can and the intake manifold, is that fine or does it need to be on the inlet?
