Description
Radium Fluid Lock PCV Catch Can Kit - Nissan Silvia / 200SX S15 (SR20DET)
Suits:
- Nissan Silvia / 200SX S15 — SR20DET
The Radium Engineering Fluid Lock PCV Catch Can Kit is a precision-engineered crankcase ventilation solution for the Nissan S15 Silvia and 200SX. Featuring large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick, this kit mounts using factory holes and integrates cleanly with surrounding components.
This is a closed loop system — it does not vent to atmosphere (VTA), making it emissions compliant and track legal. By capturing oil and sludge from PCV gases before they re-enter the intake manifold, the system promotes negative crankcase pressure for optimal performance and prevents unwanted oil vapours from entering the cabin.
No cutting, drilling, or permanent modifications required.
PCV Catch Can Kit
The PCV catch can runs inline between the PCV valve and the intake manifold, mounting to 3 OEM threaded bosses in the RH corner near the firewall. When intake manifold pressure is close to or greater than atmospheric pressure, the PCV check valve closes and flow stops. During idle, steady-state cruising, and deceleration, the PCV hoses experience metered vacuum — this would normally draw crankcase vapour, unspent fuel, and oil sludge directly into the intake manifold. The Radium catch can intercepts this before it reaches the engine.
Includes:
- Baffled oil catch can
- Nissan-specific mounting bracket
- AN adapter fittings and hose ends
- Stainless steel hardware
- Radium PCV hose
Notes:
- No extra inline check valve required — Radium catch cans are pressure sealed.
- For complete crankcase coverage, this kit is compatible with and recommended to be paired with the CCV Catch Can Kit (20-0636-FL).
- For the ultimate in engine protection, Radium recommends the full Dual Catch Can Kit (20-0637-FL) for the Nissan S15 Silvia/200SX.
