EVIL ENERGY Oil Catch Can 300ML - Baffled Separator for PCV Systems

In this review the EVIL ENERGY Oil Catch Can 300ML proves to be a practical, budget-friendly solution for owners looking to reduce oil and moisture entering the intake. It is aimed at DIY mechanics and enthusiasts who want to limit carbon buildup on intake valves and pistons without a complex install. The single biggest reason to buy is the unit's simple baffled design with removable baffle and steel balls, which captures oil effectively while remaining compact enough to fit most engine bays.

Key Features

• Baffled Design: The removable baffle plus added steel balls traps oil and moisture to help prevent carbon buildup in the intake and on valves.
• PCV System Compatibility: Can be fitted with the breather filter for pre-PCV applications or used inline between PCV hoses as a sealed catch can for modern systems.
• Universal Fit: A 300ml capacity and compact shape make it compatible with most vehicles if there is sufficient installation space.
• Durable Hose Kit: Includes a 5ft NBR hose rated for wear and heat resistance with 3/8' ID, giving flexible routing options during installation.
• Secure Ports: Inlet and outlet ports use an M161.5 thread for a reliable connection to the engine's venting system.
• Service Reminder: Weekly checks are recommended in freezing temperatures to avoid moisture-related freezing and blockages.

Who It's For

This catch can is best for car owners who perform routine maintenance and want a low-cost way to reduce oil contamination of the intake. It suits DIY installers who are comfortable drilling a mounting hole and routing hoses, and owners of older vehicles that lack a modern PCV venting arrangement.

It is not ideal for someone with a very tight engine bay where 300ml capacity and hose routing cannot be accommodated, nor is it intended as a lifetime maintenance-free solution; users should plan to inspect and clean the can periodically, especially in cold climates.

Pros & Cons

Pros

• Effective oil and moisture separation thanks to the baffled internals and steel balls.
• Versatile installation options: use with breather filter as a vent or inline as a sealed catch can.
• Includes a long, heat-resistant 5ft NBR hose for flexible routing and a secure M161.5 threaded connection.
• Good value; customers report quality comparable to higher-priced alternatives.

Cons

• Requires periodic cleaning and attention in freezing temperatures to avoid moisture freeze and blockages.
• May require drilling and sufficient clearance for mounting, so not truly plug-and-play for all vehicles.

Specifications
