OVERVIEW
The catch can draws out oil and water condensation from the crankcase gasses that would otherwise be drawn into the intake manifold. This prevents oil buildup in the intake, intercooler system walls, throttle body, and intake manifold. This effectively raises the octane, can increase engine performance from cleaner inlet air, and can lower hydrocarbon emissions. The closed system prevents unwanted oil vapors from entering into the cabin. Catch can kits include everything needed for a complete installation.
This kit installs next to the firewall and plumbs in-line between the PCV valve and the intake manifold. It maintains the OEM closed system operation of the PCV valve while keeping oil and other contaminants from entering the intake manifold. Note: Because the Radium catch cans are pressure sealed, they are safe for boosted applications, so connecting to the intake manifold is permitted without a check valve.
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.

FEATURES
- Direct fitment with no drilling required
- Large 10AN ORB inlet and outlet ports
- 4AN ORB drain port
- 2-step oil separation baffling
- O-ring sealed dipstick
- 7 fluid ounce capacity
- Patented Fluid Lock® system
COLLECTION & EMPTYING
The rate that the catch can will collect oil and moisture contaminants will vary from one specific vehicle to the next, so there is no set emptying interval. Check the oil level of the catch can using the integrated dipstick starting at 3-4 weeks of driving and repeat as needed to determine how often it should be emptied.
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, an issue with the engine may need to be addressed. 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
