I am installing a Conceptual Polymer Oil Separator. There is 1 pcv outlet on the drivers side valve cover and 2 outlets on the passenger side. The 1 on the drivers side is connected (Y connector) to the rear outlet on the passenger side then on to the PCV valve and into the throttle body. The front outlet on the passenger side is connected directly into the throttle body but not via the same port.
Is there a reason that this pcv outlet is routed directly to the throttle body and not thru the PCV valve?
Since I am trying to remove all oil from being recirculated back thru the induction, wouldn't it make sense to re-route the front outlet, via a Y connector, into the line going thru the PCV valve..........then to the oil catch can, then out to the 2 throttle body inlets (via a Y connector)?
You must be talking about something other than a C5 LS1. That's the vette/motor I'm talking about.

On a C5 LS1 the PCV comes from one of 2 locations.
On 2003 and up LS1's with the LS6 Manifold the PCV valve is in the Valley Pan (as pictured in the link provided)
On 2002 and earlier LS1's, with the LS1 Manifold, the PCV Line comes from the rear of the drivers side - Wraps around the back of the engine and comes down the passenger side along the bottom of the valve cover. The PCV valve is located
in this line about 6 inches from the throttle body.
Sorry, mine is a 2002. I should have ID'd that. The link to the pic you posted is obviously from a 2003 and up. My original question was regarding the other hose on the passenger side of the '02 which is the Clean Air Source for the crankcase.
Hey bud. I was missing the pcv valve and all the tubing. Mine is a 2001 convertible with 5.7 litre. The driver side valve cover toward the windshield ( rear) was plugged. The passenger side valve cover rear barb is capped off and the front barb has a 6AN tube running to the barb on the throttle body. They had ran a 6AN tube from the intake valley orifice to the intake barb behind the throttle body and was generating alot vacuum with nothing to regulate my crankcase pressure. I got in touch with David Childress at Mighty Mouse Solutions and he hooked me up. 4th gen LS F-body Mild. Easy to install the pcv valve is already installed in the catch can it took about 30 min from start to finish. I think you would be happy with the product.

I'd like to hear more about that one.. looks like a simple install.. how much was it?
I have a 2002 Base model that is mid-production (21 Jan 2002) and maybe this will help. I used a SickSpeed catch can I purchased for $40.00 on Amazon and used some hoses and clamps that I had in my spare parts.
I routed the hose from the left hand side valve cover that goes behind the air intake to the right sight and into the PCV valve then connected it into a black “T” bought at HD. Then routed the hose from the right hand side valve cover into the same “T” and then continued into any side of the catch can. Placing clamps on all the connections.
Out the other end of the catch can, I routed a hose into lower right nipple of the intake manifold only. Then I simply rubber capped the nipple at the upper right side of the throttle body.
Pretty simple but works fine and I hope this helps.

It was very easy. If you are not familiar with the install hit me up or hit up David Childress at Mighty Mouse Solutions. The cost was $266 for the whole kit. The pcv valve is already installed in the can.
you absolutely cannot do this.
you have to have only one line to the intake manifold, and it needs to have the pcv point of regulation directly and only in-line of it.
you have your pcv assembly (which controls how much intake manifold vacuum gets applied to the crankcase) T'd into another line which is completely uncontrolled. path of least resistance takes place and you will have uncontrolled vacuum on your crankcase. this will result in abnormally high pcv flow and side effects are high/unstable idle, excessive oil consumption, unstable oil pressure.
further, the passenger front valve cover port has two specific jobs for PCV that you defeated. 1 it is the fresh air supply to the engine. 2. it is the main crank pressure vent. these are both critical to pcv operation.
this type if information and customer support is part of what you get when you throw a few more bux at your catch can system.
