Radium Engineering Fluid Lock Dual Catch Can Kit - Nissan Silvia (S13 SR20DET)
This Radium Engineering Fluid Lock dual catch can kit (SKU 20-0727-FL) combines Radium's PCV (20-0725) and CCV (20-0726) catch can kits for the Nissan S13, giving complete crankcase ventilation coverage. Both cans are closed loop, so oil and sludge are removed from crankcase gases before they are routed back to be burned, with nothing vented to atmosphere.
The PCV can runs between the PCV valve and intake manifold and mounts to threaded bosses on the right-hand strut tower, just clear of the fuel filter. The CCV can runs between the crankcase vent and the intake pipe, catching the high flow of blow-by at wide open throttle, and mounts to two holes on the left-hand side of the body near the firewall, clearing the wiper motor (RHD) and master cylinders (LHD).
Note: No extra inline check valve is needed as Radium catch cans are pressure sealed. The kit connects the supplied hose to the OEM valve cover barb; an SR20DET add-on option is available separately. Check the levels with the dipsticks from around 3–4 weeks of driving and empty as needed. Installation by a professional is recommended.
