Strange, did the catch can have any oil in it?
Ok I just looked at the Norris webpage and it looks like Im wrong, they have it setup like you (although I swear I've seen it hooked up like mine). But doesn't my logic about it sound right though?

Been fighting a rear main area leak for a while now, I think this is what was doing it.
If you pull the PCV valve hose off the can with the engine running and put your thumb over the hose, the pcv valve clicks like it should now.
The throttlebody actually had oil puddled in it, intake runners were really wet.
EDIT
I had to change water pump gaskets this past Saturday, the throttle body is now dry and the intake just has a leftover film in it. Rear main is area is now dry.
The can had a good bit of oil in it since I swapped it around.
I opened the can up and looked inside, it has a deal sticking down lower than the side inlet. So the oil comes into the side from the LS6 valley cover and hits this parts and falls to the bottom.
Has a filter screen in it where the top exit is.
So I feel I have it right now.

TTT I read this thread, but I am still unclear as to how to run a Whipple catchan setup.
From my understanding I can Tee both covers to the top port catchcan and the bottom port goes between the TB and blower (no checkvalve needed with PD blower).
Is this where it gets is fresh air source from? What about PCV valve, I know its basically like a checkvalve, where does it go, do I need one?

After reading through this thread, I still have a question; however, that was a lot to take in (especially in the middle of doing stat homework), so forgive me if this is a redundant question...
I see some people saying they've done the LS6 valley cover and everything is now dry. If that's the case, what would the point of the catch can be? Why not just spend <$100 for the LS6 conversion and be done?

I have an LS6 valley cover and catch can. It seems every diagram here has the passenger side valve cover venting, but not all of them show the drivers' side venting due to the LS6 valley cover conversion. I interpreted this to mean that the drivers' side valve cover does not necessarily have to vent. Can I use this logic to remove the venting on the passenger's side as shown below?

BTW Gm makes plugs for the drivers side valve cover to close the hole in the valve cover.
See, I already have the plug on the Drivers' side that you mentioned. With the plug on the Drivers' side, the Drivers' side valve cover is not venting, correct? So why is it necessary that the passenger side valve cover vents if my catch can is routed from the LS6 valley cover to the intake with a truck PCV valve?
I'll hook it up if I have to, but I really don't want to if the venting from the valley cover is enough...
But it's getting air from the valley cover... LS6 valley cover, right?

Your PCV is not working, for it to work it has to pull air through the engine, as it is now it cant because the other end of the straw(passenger valve cover) is blocked off.
I'll hook it back up this evening, thanks again for the replies

how can i tell if i have a ls6 style valley cover, my car is a 01, i believe it has a ls6 intake, i would like to get a catch can but i would also need to know what i have in order to route it the right way
Update, I'll be updating all of the diagrams in my posts over the coming weeks. Hopefully this will reduce confusion and answer many of the questions posed here.
I've been a way from the forum for a while so bare with me.

Most questions everyone keeps asking have been answered numerous times already, so its definitely worth reading the entire thread.
I wish I had found this earlier... I've had an empty catch can and oil still in the intake for months now. I'm hooked into the clean air side... Derp.
Diagrams were very helpful thank you!!!!!
