EVIL ENERGY Oil Catch Can 300ml Aluminum - Universal Baffled PCV Tank with Breather Filter

EVIL ENERGY’s 300ml universal baffled oil catch can is an aluminum PCV/vent tank that captures oil mist and blow-by vapors before they re-enter the intake system.

This compact 300ml catch can kit arrives with fittings, a baffled internal chamber, NBR fuel hoses and the option to mount a breather filter. Designed to fit a wide range of vehicles, it offers both sealed inline operation for cars with a PCV system and an open-vent configuration when used with the included breather. Measure your existing hose inner diameter and mounting space before ordering to ensure the correct fit. Professional installation is recommended for best routing and leak-free connections.

How does this catch can reduce oily deposits in the intake?

The baffled internal design slows incoming crankcase gases so oil droplets coalesce on the tank walls instead of traveling back into the intake manifold. Collected oil settles to the bottom where it can be drained during service intervals, reducing carbon buildup on intake valves and sensors. It does not alter engine design — it intercepts condensate and blow-by before it reaches sensitive components.

• 300ml aluminum tank with internal baffle for oil separation
• Drainable sump for periodic removal of condensed oil
• Option to run sealed inline or vent to atmosphere via breather

Will this fit my vehicle and how do I choose the right connection?

This catch can is universal but not one-size-fits-all — check the inner diameter of your existing PCV or crankcase hose to confirm compatibility. The kit’s hose measures 2.6 ft (0.8 m) with a 3/8" inner diameter and 2/3" outer diameter; the inlet/outlet threads are M16×1.5. If you’re unsure, compare the measurements or consult a mechanic to match fittings and verify available mounting space.

• Hose length: 0.8 m (2.6 ft); hose ID: 3/8", OD: 2/3"
• Thread size: M16×1.5 for inlet and outlet ports
• Capacity: 300 ml; check under-hood clearance before purchase

Should I use the breather filter or run it inline with the PCV?

You can install the catch can with the breather filter for engines that lack a PCV system, allowing crankcase gases to vent to atmosphere through the filter. For modern engines with a functioning PCV, install the can inline between PCV hoses to maintain a sealed system while still capturing oil vapor. Choose the configuration that matches your vehicle’s emission and ventilation setup.

• Use breather filter for pre-PCV or venting setups
• Run inline (no breather) for sealed PCV systems
• Adaptable installation depending on vehicle requirements

How often should the catch can be checked and cleaned?

Inspection frequency depends on driving conditions, oil consumption and ambient humidity. In cold climates or when temperatures approach freezing, excess moisture can accumulate and increase freeze risk — check more often. Empty or clean the can when oil level reaches the recommended mark or during regular maintenance intervals to avoid overflow and maintain separation efficiency.

• Inspect weekly in freezing or high-moisture conditions
• Empty when oil reaches marked level or during service
• Follow professional installation guidance for optimal placement

Who is this for: The EVIL ENERGY 300ml baffled catch can kit is suited for enthusiasts and technicians who want a compact, universal solution to reduce oil vapor recirculation. It’s a practical option for vehicles that see spirited driving, tow frequently, or run in variable climates where blow-by and moisture are concerns. Confirm hose sizes and mounting room before purchase and consider professional installation to ensure a secure, leak-free setup.
