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. 

20-0635 CATCH CAN KIT, PCV, NISSAN S15 SILVIA/200SX
The PCV catch can kit runs inline between the PCV valve and the intake manifold. It mounts to 3 OEM threaded bosses in the RH corner near the firewall.  

When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hoses will experience "metered" vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run. 

INCLUDES
-Baffled oil catch can
-Nissan specific mounting bracket
-AN adapter fittings and hose ends
-Stainless steel hardware
-Radium PCV hose

NOTES:
1. The PCV catch can kit is compatible and recommended to be used with the CCV catch can kit. See 20-0636 below.
2. No extra inline check valve is required since Radium catch cans are pressure sealed.

20-0636 CATCH CAN KIT, CCV, NISSAN S15 SILVIA/200SX
The CCV catch can mounts to 2 of the wiper blade motor mounts.

To retain factory functionality, the CCV catch can runs inline between the crankcase vent (CCV) port and the intake pipe. At low loads, it experiences atmospheric pressure. However, when the engine is at high load (WOT), the line will experience high flow from the crankcase into the intake system. This would normally lead to oil and sludge accumulation in the air filter intake pipe. This oil accumulation would spread and be found in the intercooler which lowers the thermal efficiency properties of the heat exchanger and leads to decreased performance. The CCV catch can captures this and promotes clean filtered air back into the intake.

INCLUDES
-Baffled oil catch can
-Nissan specific mounting bracket
-AN adapter fittings and hose ends
-Stainless steel hardware
-Radium PCV hose

NOTES: 
1. The CCV catch can kit does NOT address blow-by from the PCV valve side of the crankcase.
2. The CCV catch can kit is compatible and recommended to be used with the PCV catch can kit. See 20-0635 above.

20-0637 DUAL CATCH CAN KIT, NISSAN S15 SILVIA/200SX
