Radium Engineering PCV Fluid Lock Catch Can Kit - Nissan 350Z Z33 / Skyline V35 / Infiniti G35 V35 (VQ35DE)
Application: Nissan 350Z / Fairlady Z (Z33), Nissan Skyline (V35) and Infiniti G35 (V35) - VQ35DE only
Part Type: PCV Fluid Lock oil catch can kit
Part Number: 20-0728-FL
The Radium PCV catch can kit runs inline between the PCV valve and the intake. At idle, steady-state cruise and deceleration the PCV hose sees metered vacuum, which draws crankcase vapour, unspent fuel and oil sludge into the intake manifold - the catch can traps these contaminants before they re-enter the engine. Radium catch cans are pressure sealed, so a direct intake manifold connection is permitted and no extra inline check valve is required.
The can mounts to the OEM power steering reservoir bracket with no drilling. Radium's patented Fluid Lock system (introduced with the 2022 redesign of its 7 fl oz catch can) prevents overfilling and traps collected fluids until the can is emptied, so an unserviced can can't release contaminants back into the intake.

Radium Catch Can Petcock Drain Kit (20-0024) - easier draining where space allows
Important Notes
- Not compatible with VQ35HR engines - they have a non-compatible power steering reservoir mount
- No fixed emptying interval - check the integrated dipstick from 3-4 weeks of driving; PCV cans typically collect more than CCV cans. Empty by unscrewing the lower reservoir, or fit the Petcock Drain Kit where space allows
- Excessive oil collection can indicate an engine issue such as excessive blow-by, crankcase windage from overfilled oil, poor breather port placement or baffling, or a PCV valve leaking under load
