      Oil catch can

      Hey guys wondering if i can get some input if i installed my catch can correctly. I have the “out” port connected to the port right behind throttle body and the “in” port connected to passenger valve cover.

      Valley port and driver side valve cover are capped

      I have been hearing that the valley port must be on vaccum

      Any suggestions or help is greatly appreciated



      Engine is an LS3 of course lol

      That sounds wrong. Catch can replaces the corrugated hose between the throttle body and valley cover. In connects to the valley cover, out to the throttle body. Fresh air feeds from the intake tube (between the MAF and throttle body) to the valve cover.

      Ok so you can get the fresh air from anywhere you like. But you need fresh filtered air to the valve cover.

      The way you have it plumbed now has no fresh air supply. That’s not good....

      Q; wouldn’t it work putting it inline between the pcv and the intake (I’m working with a TBSS intake and am assuming the LS3 intake has a similar setup)?
