Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick. These kits mount using factory holes and integrate perfectly with the surrounding components. They do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin. The dipsticks built into the catch cans allow easy inspection of accumulated fluid. No cutting, drilling or permanent modifications are required.
 
The PCV catch can kit runs inline between the ventilation valve and the intake pipe. It mounts to threaded bosses on the front radiator support. This location stays clear of aftermarket parts such as an upgraded turbocharger or intake tubing.  
 
The PCV catch can traps unwanted "metered" crankcase vapor, unspent fuel, and oil sludge. It promotes clean filtered air back into the turbocharger inlet.
