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
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.
