EVIL ENERGY Oil Catch Can 300ml - Universal Baffled PCV Separator

In this review the EVIL ENERGY Oil Catch Can proves to be a practical, budget-conscious upgrade for owners looking to reduce oil and vapour from entering the intake and PCV system. The unit is a compact 300ml aluminum separator with an optional breather filter, aimed at hobbyists and DIY mechanics who want straightforward installation and reliable oil separation without paying for premium-brand alternatives. It stands out for simple fitment, a choice of vented or sealed setups, and clear installation notes for cold climates.

Key Features

• Universal fit: The kit is designed to fit most cars as long as there is adequate space for mounting, making it useful across many applications.
• 300ml capacity: The aluminum tank holds 300ml of collected oil and condensate so it can be emptied at regular intervals without frequent maintenance.
• Optional breather filter: The catch can can be run with the breather for pre-PCV vented systems or without it inline between PCV hoses for a sealed setup.
• Complete hose kit: Includes 2.6ft (0.8m) hose with a 3/8 in ID and 2/3 in OD and M161.5 inlet/outlet threads to enable direct connections to common PCV and crankcase fittings.
• Baffled design: Internal baffling helps separate oil and vapour effectively so less oil reaches the intake and valves over time.
• After-sales support: The seller offers returns or exchanges for quality issues and maintains customer support for installation questions.

Who It's For

This product is aimed at DIY car owners, tuners and maintenance-minded drivers who want to reduce oil contamination in the intake tract or preserve intake valve cleanliness on older or modified engines. It is especially suitable for those who prefer a simple, do-it-yourself installation and a choice between vented or sealed operation.

It is less appropriate for users who need a brand-specific engineered solution for tight engine bays where custom fittings or very short hoses are required, or for shops seeking a fully managed OEM-level part with vehicle-specific instructions.

Pros & Cons
