Radium Engineering PCV Catch Can Kit For 2022+ Subaru BRZ, 22+ GR86 - Fluid Lock - 20-0911-FL

CATCH CAN KITS, 2022+ BRZ/GR86

COMPATIBILITY

The catch cans are strategically located for compatibility with Right Hand Drive (RHD) and Left Hand Drive (LHD) variations. Minor brake line clearancing is necessary on RHD installations. For mounting, the kits use factory bosses and holes on the chassis. No cutting, drilling or permanent modification to the vehicle are required.

OVERVIEW

The PCV kit mounts on the RH side of the engine bay.

This catch can runs inline with the 5/8" PCV (positive crankcase ventilation) valve. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience "metered" vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run.

NOTE: Because the Radium Engineering catch cans are pressure sealed, they are great for boosted applications as well. Connecting to the intake manifold is permitted.

Fluid Lock Catch Cans
In 2022, Radium Engineering implemented a revolutionary design change to the 7 fluid ounce standard catch can. An inherent problem always existed with typical catch cans when not serviced regularly. The fluid contaminants will eventually leave the reservoir pouring into the air intake system causing poor engine performance. To resolve this issue, Radium created the Fluid Lock® Catch Can. This contains a patented mechanism that prevents the reservoir from overfilling and traps the collected fluids until it is emptied.

Collection & Emptying
The rate that your catch cans will collect oil and moisture contaminants will vary from one individual vehicle to the next, so there is no set emptying interval. PCV catch cans tend to collect more than CCV catch cans. You should check the level of your catch can using the integrated dipstick starting at 3-4 weeks of driving and repeat as needed to determine how often they should be emptied based on what you see.

Catch cans can be emptied by unscrewing the lower reservoir and removing it from the vehicle to dump out, or in cases where there is available space under the catch can, the Petcock Drain Kit can be installed and used to drain them.

In cases where oil collection is excessive you may have to address an issue with the engine. The reasons a catch can will collect an excess of oil include

• Excessive blowby from engine damage
• Crankcase windage from an over-full oil level
• Poor placement of breather ports and/or poor baffling inside breather ports
• PCV valve not closing and leaking under heavy load
