In that case the metal part is facing the intake (catch can), the rubber boot end goes (faces) to the valley. Judging by everything you've said and your diagram you've proven it is in fact set up properly. Thanx.

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.

That's the way it is. If you look at the picture, the hose between the catch can and the pcv valve has a clamp at the end near the boot. That clamp is clamped on the 3/8ths end of the valve, which is facing the intake. The other end of the valve (1 inch) is inserted into the boot and facing the valley cover. Correct according to this diagram.

Now if someone can explain why the other guy said the valve should be after the can then we'll be just about done here.

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.

Exactly, this is backwards. You have to consider the flow of air into and out of the valley. Look at the way the PCV is situated in a stock system and consider how the air flows; in your current setup the PCV valve is flipped 180 degrees compared to the way it's situated stock. Look at the diagram I posted earlier. This shows how and when the PCV valve opens and closes based on engine speed.

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.

JEEZ! The nipple is facing the intake (not literally). It faces into the catchcan, hose leaving catch can faces intake. Therefore the nipple end is facing the intake. Thanks for wasting everyones time.

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.

I got one guy telling me the valve needs to be "flipped around", he is wrong cause the 1inch end goes toward the valley and the 3/8ths end goes toward the intake. Then you told me the valve should be connected to the intake instead of valley but then change that to "it doesn't matter if it's before or after the intake", now you say the lines are "backwards", whatever that means.

It is before the catch can. And facing the correct way.

hey we're just trying to help... do what you want its your car.

Trying to help how? 1inch goes toward valley/valve cover, 3/8ths to the intake. Before/after can doesn't matter. (according to both of you) That's how it is.

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.

If you were to put the valve before your can instead of after it would be flipped around.
