where do you route the vent tube from the valley cover? i saw that the ls1's use the pcv valve but the tbss intake doesnt have one. So do i tee into one of the valve cover vents or what? I'm going to be putting one on soon and i need to know how to route this tube.

thanks

 

C'mon someone's gotta know the answer to this

 

Black nipple on top of intake where the truck valve cover mounted PCV line goes to. You need to make sure you've got a PCV valve or Orofice (constant size PCV regulating passage) between the valley cover outlet and the nipple on the top of the TBSS intake. It would also be VERY wise to toss a catch can inline there too.

 

So do I need to go buy a PCV valve and put that inline of the vent tube? Would I block off the driver side rear valve cover port or tee into that line?

 

Block it off, or run it up to the passenger side valve cover fresh air line and T it in with that as you'll be drawing crank case vapors only from the valley cover. I would put a catch can as well in line between the PCV valve and the nipple on the top of the TBSS intake. To make sure you don't draw oil mist from the fresh air side into the intake tube/throttle body, you can throw a catch can inline with that too.
