Crankcase ventilation

[Kracka]

Everyone thinks they can out-engineer the engineers. From my experience, catch-cans seem to create more problems than they solve. Setting it up like stock always puts a suction on either the crankcase vent or PCV vent which is better than just allowing excessive pressure build up to escape on it's own. If that solution doesn't work, then do the same, only with larger lines. Having a little oil vapor/mist in your intake charge is actually a good thing since it helps keep the BOV and wastegate actuator internals lubricated.
