A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin.One catch can plumbs inline with the PCV (positive crankcase ventilation) valve and retains it's factory function.

Conversely, the PCV hose will experience "metered" va
