EVIL ENERGY 300ml Baffled Oil Catch Can Kit with Breather Filter – Universal PCV Oil Separator

Removable Baffle with Optional Metal Filtering Media

The EVIL ENERGY catch can includes a removable internal baffle intended to improve separation of oil mist from crankcase gases.

The manufacturer also describes the use of metal filtering media, such as steel balls, inside the collection chamber.

Additional surface area can encourage oil droplets to coalesce and collect in the reservoir.

However, only suitable, securely retained filtering media should be used.

Installation warning: Loose steel balls or other unsecured material should not be placed inside a catch can where they could obstruct ventilation passages or enter the engine’s intake system.

Included Breather Filter: Open vs. Closed PCV Systems

The included breather filter distinguishes this version from the standard EVIL ENERGY two-port catch can.

It provides an additional configuration option for engines designed to use an appropriate open crankcase ventilation arrangement.

Open-Vent Configuration with Breather Filter

Certain older engines and specialized competition applications use vented crankcase systems.

In an appropriate setup, the breather filter allows separated crankcase gases to vent while helping reduce the release of larger oil droplets.

However, the filter does not necessarily capture all oil aerosol or eliminate emissions.

Closed PCV Configuration Without Breather Filter

Most modern street-driven vehicles use a closed PCV system.

In these applications, an appropriately configured catch can is installed inline while preserving the original ventilation function.

The breather filter should not be added simply because it is included with the kit.

Opening a closed PCV system can introduce unmetered air, create vacuum leaks, interfere with crankcase pressure regulation, and violate applicable emissions requirements.

EVIL ENERGY 300ml Catch Can Specifications

The supplied product description does not confirm the catch can’s housing material, finish, mounting bracket configuration, or complete fitting assortment. These details should be checked against the exact product variant before publication.

300ml Capacity for Custom Engine Installations

The EVIL ENERGY catch can features a nominal 300ml collection reservoir, equivalent to approximately 10.1 US fluid ounces.

This capacity can provide a useful balance between collection volume and packaging for certain compact engine bays.

However, the amount of oil and moisture collected varies considerably.

Factors include engine condition, operating temperature, driving frequency, boost pressure, crankcase ventilation design, and ambient weather conditions.

Inspect the reservoir frequently after installation to determine an appropriate maintenance interval.

Universal Fitment: What Vehicles Can Use This Catch Can?

The EVIL ENERGY 300ml baffled oil catch can is a universal aftermarket product.

It is not manufactured as a direct-fit kit for any specific year, make, or model.

Fitment warning: These are potential custom applications, not confirmed direct-fit installations. Some engines require multiple ventilation circuits, integrated separators, or specialized pressure-control components.

How to Install the EVIL ENERGY 300ml Catch Can

1. Identify the engine’s existing crankcase ventilation system.

2. Determine whether a sealed or open-vent catch can configuration is appropriate.

3. Measure the original PCV hose inside diameter.

4. Verify compatibility with the included 3/8-inch hose and required fittings.

5. Select a mounting location away from exhaust heat, belts, fans, and other moving components.

6. Secure the catch can with appropriate mounting hardware.

7. Install the M16 × 1.5 fittings according to the manufacturer’s instructions.

8. Connect the catch can to the appropriate crankcase ventilation circuit.

9. Install the breather filter only if the engine’s ventilation design and applicable regulations permit it.

10. Inspect all hose connections and verify that crankcase ventilation remains unrestricted.

11. Start the engine and check for vacuum leaks, abnormal crankcase pressure, and other installation problems.

Professional installation is recommended.

Important Installation Precautions

• Never block or severely restrict crankcase ventilation.

• Do not remove required PCV valves or pressure regulators without an engine-specific design.

• Do not add a breather filter to a modern closed PCV system without verifying compatibility.

• Do not overpack the catch can with filtering media.

• Do not route hoses near exhaust components without appropriate heat protection.

• Do not assume the supplied 3/8-inch hose fits every engine.

Cold Weather Warning: Catch Can Freezing

Crankcase ventilation systems can produce substantial condensation during cold-weather operation.

When temperatures reach freezing, accumulated water inside the catch can or hoses can freeze.

This can obstruct crankcase ventilation and cause excessive pressure, oil leaks, or other engine problems.

EVIL ENERGY recommends inspecting and cleaning the catch can weekly during freezing conditions or returning to the original PCV hose configuration when appropriate.

For vehicles operated regularly in cold climates, consider the engine manufacturer’s cold-weather ventilation requirements before installing an aftermarket catch can.

How Often Should You Empty the Oil Catch Can?

Maintenance frequency depends on the amount of blow-by, moisture accumulation, driving conditions, and ambient temperature.

Check the reservoir frequently after installation, especially during short-trip driving or cold weather.

Empty collected fluid before it reaches a level that could interfere with the internal baffle or ventilation passages.

Inspect the hose connections, fittings, seals, and breather filter during routine maintenance.

Frequently Asked Questions

Does this EVIL ENERGY catch can include a breather filter?

Yes. This specific version is advertised with a breather filter.

What is the capacity?

The catch can has a nominal 300ml collection capacity.

What hose size is included?

The supplied hose is approximately 2.6 feet long with a 3/8-inch inside diameter.

What thread size are the inlet and outlet ports?

Both ports are specified as M16 × 1.5.

Will this catch can prevent carbon buildup?

It may reduce oil mist entering the intake in an appropriate closed-PCV installation, but it cannot guarantee the prevention of carbon deposits.

Can I install this on a Lexus IS300?

It may be adapted to a compatible PCV circuit on a first-generation Lexus IS300, but hose dimensions, mounting clearance, and the factory ventilation arrangement must be verified. The breather filter should not automatically be installed.

Should I use the breather filter on a modern EFI engine?

Generally, modern street-driven engines should retain their designed closed PCV systems. The breather filter is intended only for compatible ventilation configurations.
