Radium Engineering Nissan S15 Silvia/200SX Catch Can Kit PCV Fluid Lock - 20-0635-FL

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.

NOTES

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