Is installing a fitting on the intake of the turbo the same as installing one on the intake manifold? I know the turbo intake sucks but then it pushes and then when the throttle body closes the one half stops taking air in. To me this sounds different. The reason i ask is that i see some guys run a hose from both pcv valves to the catch can. This doesn't seem correct to me seeing as how these two spots on the intake react differently from each other. Can anyone clear this up?
