LS6 valley cover pcv system I just upgraded to an ls6 valley cover that eliminated the crossover from the driver's side valve cover to the passenger's. I know most people just plug that port and call it a day. I'm running forced induction.
Is there any benefit to run a fresh air hose on that rear port? I'm referring to a hose just like how the passenger's side valve cover has in the front that on procharged systems runs from the valve cover to the intake tube before the supercharger. I can't find the thread, but I remember someone saying he ran two hoses for fresh air since the added crankcase pressure from forced induction requires more ventilation. However, I can't see this helping at all since there will still only be one pcv port going from the valley cover to the manifold so it will act as a limiting factor.
