Radium Engineering PCV Fluid Lock Catch Can Kit for Nissan Silvia/200SX S15 SR20DET

Radium PCV Fluid Lock Catch Can Kit - Nissan Silvia/200SX S15 (SR20DET)

Application: Nissan Silvia / 200SX S15
Part Type: Fluid Lock PCV oil catch can kit
Part Number: 20-0635-FL

The Radium PCV Catch Can Kit for the S15 Silvia and 200SX separates oil and water condensation from crankcase gases before they reach the intake, helping keep the intake manifold and throttle body clean.

The PCV can runs inline between the PCV valve and the intake manifold, mounting to three OEM threaded bosses in the RH corner near the firewall. At idle, cruise and on deceleration it captures crankcase vapour, unburnt fuel and oil that manifold vacuum would otherwise draw into the intake.

Key Features

• Closed Loop: Does not vent to atmosphere
• Fluid Lock: Patented design prevents overfilling and traps collected fluid
• Large Ports: 10AN ORB inlet and outlet, 4AN ORB drain
• Two-Step Baffling: Separates oil from crankcase gases
• O-Ring Sealed Dipstick: Check oil level without removing the can
• Direct Fit: Nissan-specific bracket, no drilling required

What's Included

• Baffled Fluid Lock oil catch can
• Nissan-specific mounting bracket
• AN adapter fittings and hose ends
• Stainless steel hardware
• Radium hose

Optional Parts

• Radium Fluid Lock CCV Catch Can Kit - Nissan Silvia/200SX S15 (SR20DET) (20-0636-FL) – pair with the PCV kit for complete crankcase coverage
• Radium Dual Fluid Lock Catch Can Kit - Nissan Silvia/200SX S15 (SR20DET) (20-0637-FL) – PCV and CCV kits combined
• Radium Catch Can Petcock Drain Kit (20-0024) – drain the can without removing the lower reservoir, where there is room underneath

Important Notes

• No additional inline check valve is required – Radium catch cans are pressure sealed
• Radium recommends pairing this kit with the CCV Catch Can Kit (20-0636-FL)
• Radium's Fluid Lock design (introduced 2022) uses a patented mechanism that prevents the can from being overfilled and holds collected fluid until it is emptied
• There is no fixed emptying interval – start checking the dipstick after 3–4 weeks of driving and adjust from there; PCV cans typically fill faster than CCV cans
• Installation instructions are available in the Instructions tab
