EVIL ENERGY Oil Catch Can 300ML Baffled Design - Cleaner Intake

Our review of the EVIL ENERGY Oil Catch Can finds it best suited for drivers who want a compact, effective way to reduce oil and moisture entering the intake system. The single biggest reason to buy is its baffled design, which traps oil and condensation before they turn into carbon deposits on valves and pistons, helping maintain performance without the complexity or cost of larger catch tanks. Installation is straightforward for most hobbyists and DIY mechanics, and the included hose kit makes it a practical upgrade for many vehicles.

Key Features

• Baffled Design: The removable baffle and steel-ball damping help separate oil and moisture so less contamination reaches the intake and valves.
• PCV System Compatibility: Can be fitted with the breather filter for pre-PCV venting or installed in-line between PCV hoses as a seal can for post-PCV systems.
• 300ml Capacity: Compact 300ml volume provides a useful reservoir for catchment while remaining small enough for tight engine bays.
• Durable NBR Hose Kit: The supplied 5 ft NBR hose (3/8 in ID) resists heat and wear, giving a long-lasting connection between engine and catch can.
• M16 Threaded Ports: Inlet and outlet ports with M161.5 threads offer a secure, consistent attachment point for fittings and hoses.
• Maintenance Note: Easy weekly cleaning prevents moisture freeze in cold weather and preserves flow through the crank vent system.

Who It's For

The EVIL ENERGY catch can is ideal for DIY mechanics, performance-minded drivers, and owners of older engines prone to oil vapour recirculation and carbon buildup. Its universal fit and small footprint make it a practical choice for cars where space is limited but the owner still wants to protect intake ports and valves.

It is less suited for owners unwilling to perform occasional maintenance or those in extremely cold climates who cannot check or drain the unit regularly, since increased moisture in freezing conditions can risk blockage unless the system is inspected and cleaned weekly or reverted to the original PCV hose.

Pros & Cons

Pros

• Effective oil and moisture separation from the baffled design, reducing carbon buildup risk.
• Includes a long, heat-resistant NBR hose and secure M16 threaded ports for reliable connections.
• Simple installation and good build quality make it a strong value compared with pricier alternatives.

Cons

• Small 300ml capacity requires more frequent draining on some engines compared with larger tanks.
• Needs regular cleaning in freezing climates to avoid moisture-related blockages.

Our Verdict

The EVIL ENERGY 300ml oil catch can is a compact, well-made option for owners who want to reduce intake contamination without a complex install. It delivers effective oil separation, a durable NBR hose, and flexible PCV or breather installation. For drivers prepared to perform periodic drain and cleaning, it represents good value and solid protection for intake components.

Frequently Asked Questions

Can this be used with both PCV and non-PCV systems?
Yes. Install with the breather filter for pre-PCV venting or run it inline between PCV hoses as a sealed can for systems with a PCV valve.

How often should the catch can be drained?
Drain intervals depend on engine and driving habits, but check regularly; weekly inspection is advised in cold, moist conditions to prevent freezing and blockages.

Is the included hose durable enough for engine bay use?
Yes. The kit uses NBR hose known for wear and heat resistance, suitable for typical engine bay temperatures.
