where is my pcv valve? on a tvs2300 magnusion - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

anybody know where the pcv valve is on a 2010 ls3, manual trans, with tvs2300 supercharger. It looks like the pcv valve was in the stock intake manifold. so when the supercharger was installed shouldn't it have come with a pcv valve. its been this way for 7 years now.

so I found the tvs2300 install manual. when the center oem valley cover was replaced with the magnusion center valley cover the front vent tube coming out of the cover was deleted. and the rear drivers side valve cover had a cap covering the tube coming out of the valve cover. and from there a hose runs to the supercharger.

I looked on my oem intake and there is no pcv built into any of the tubes coming out.

I found this on a search online, "There is none. It is a fixed orfice with a tiny hole that barely allows the crankcase to breathe and it clogs over time. We use the rear of the passenger side valve cover barb and cap the valley.

And another place I found for the v-6 don't says they don't have, "The 3.6 has been notorious for getting oil into the intake system.
First of all there is no PCV valve like older cars, there is a Crankcase Ventilation orifice that limits the flow of air goes into the crankcase.
The reason people use oil catch cans is to precipitate the oil out of the air stream prior to getting into the intake manifold.
Up to 2013 the Crankcase Ventilation Orifice was too small creating high velocity picking up too much crankcase oil as it was ventilating the crankcase, in 2013 GM increased the holes in the orifice thereby slowing down the velocity and also the amount of oil. A good catch can will help in reducing the oil in the intake.
You can also remove the orifice and drill out the holes to the new sizes.

I'm begining to think I don't have one on my ls3.

Ted cleared it up. the orifice is in the left rear drivers tube also.
