Radium Engineering PCV Fluid Lock Catch Can Kit for Subaru WRX VB 2022+

Radium PCV Fluid Lock Catch Can Kit, Subaru WRX VB (2022+)

Application: Subaru WRX VB (2022+)
Part Type: PCV-side oil catch can kit (Fluid Lock)
Part Number: 20-0754-FL

A Radium catch can draws oil and water condensation out of the crankcase gases before they reach the intake, helping keep the intake tract, intercooler, throttle body and intake manifold clean and keeping oil vapour out of the cabin. Radium's patented Fluid Lock design, introduced in 2022, stops the reservoir from overfilling and holds collected fluid until the can is emptied, so it can't be drawn back into the intake.

The 20-0754-FL PCV kit runs inline between the PCV valve and the intake manifold, catching the crankcase vapour that would otherwise be drawn into the intake manifold after high-load driving. The can mounts to threaded bosses on the ABS unit with a WRX VB-specific bracket, and the kit includes everything needed for installation.

Key Features

• Fluid Lock: Patented design prevents overfilling and traps collected fluid until emptied
• Large Ports: 10AN ORB inlet and outlet ports
• Easy Draining: 4AN ORB drain port; optional petcock drain kit available
• Oil Separation: 2-step oil separation baffling
• Dipstick: O-ring sealed dipstick to check the fluid level
• Capacity: 207 mL (7 fl oz)
• PCV Circuit: Inline between the PCV valve and intake manifold
• Direct Fit: Mounts to threaded bosses on the ABS unit – no drilling required
• Pressure Sealed: No additional inline check valve required

What's Included

• Baffled Fluid Lock oil catch can
• WRX VB-specific mounting bracket
• 12AN adapter fittings and hose ends
• 3/4" PCV hose
• Stainless steel hardware

Optional Parts

• Radium CCV Fluid Lock Catch Can Kit, Subaru WRX VB (2022+) (20-0755-FL) – Radium says the PCV kit works best paired with the CCV kit
• Radium Dual Fluid Lock Catch Can Kit, Subaru WRX VB (2022+) (20-0756-FL) – PCV and CCV kits together (Radium recommended)
• Radium Catch Can Petcock Drain Kit (20-0024) – drain the can without removing the reservoir, where there is room

Important Notes

• Addresses the PCV side only – it does not catch blow-by on the CCV side
• At idle the PCV valve closes and vacuum can pull the large 3/4" hose flat; Radium says this is cosmetic and the system still works – optional hose support springs prevent it
• There is no fixed emptying interval – check the dipstick from 3–4 weeks after installation, then as required; PCV cans typically collect more than CCV cans
• Excessive oil collection can indicate an engine issue such as blow-by, overfilled oil, poor breather placement/baffling or a PCV valve that doesn't close under load
• Installation instructions are available in the Instructions tab
