Which end does the nipply part face? There was oil in the catch can btw...

The PCV is metal, however the OEM boot it's in is a rubber material. The valve actually slips into the boot, and the boot should have a metal clamp-like deal that snaps around the boot and valve to hold them together. The clamp is also attached to the water crossover pipe if this helps.
Maybe someone has already jacked with your PCV system already...

To try to clarify a little more, if you were to pull the PCV out, there will be one end that is about 3/8 of an inch and the other end will be about an inch. The large end would go toward and into the boot and the 3/8-inch end would go into the intake, via a short two inch extension hose that has a small bend in it. From what you've posted, it seems we are on the same page.

Yes, but only one metal side sticks out of the rubber 'boot' it fits in. One end of the PCV valve is flat and the other has a nipple. The nipple should point at the intake and the flat side should point at the passenger side fender or right front wheel of the car.
As far as which hose the PCV valve is located, I've seen no data that points to either side being right or wrong as long as the PCV valve is situated correctly. I happen to have mine after the dirty side catch can, but you can do either.

lol.... no, the pcv valve itself is facing the right way, but it is NOT connected to the right source. It needs to be connected to the intake. Yours is connected to the ls6 valley port!!
Yep, now after looking closer the PCV is pointing in the correct direction of flow. With the PCV on the valley side it just doesn't look right. Sorry for my brief confusion. Dude, this isn't a stock setup, their is a catch can in the middle. So all your saying is the pcv valve should be after the catch can instead of before it. Correct? I disagree.
it doesnt matter if the pcv valve is before or after the catch can. the line on the top of the can needs to go into the intake manifold!
edit, and the line going into the ls6 pcv needs to be connected to the bottom port on the catchcan

As I stated earlier, you can put the PCV valve on either side of the catch can. I know of no data that suggests it's better on one side than the other. Some say it's better before the catch can because the PCV valve requires some oil to operate correctly.
Gravity isn't the only force in the equation. Pressure, leak down, and engine operating range are the other variables at work in the PCV system. Gravity will not take all or even most of the oil to the bottom of an empty catch can because most of the oil that is carried through the system is in vapor form. Some form of condensing material or filter is required inside the catch can to help the vapor condensate and in-turn collect in the bottom of the catch can. Under long periods of WOT (i.e. open track and road racing) there is sufficient pressure to push most of the oil vapor through an improperly designed catch can and into the intake.
