Why Install an Oil Catch Can?

Modern direct injection engines commonly route crankcase vapors back through the intake system using the PCV system. Over time, oil vapor and condensation can accumulate inside the intake manifold and on intake valves, leading to carbon buildup and reduced efficiency.

An air oil separator helps capture contaminants before they recirculate through the engine.

Translation: less oily sludge where oily sludge absolutely should not be.

[Installation Location]:Generally you best need an air oil separator at the PCV side of the engine.

Features

• Direct-fit air oil separator system
• Compact 3oz oil catch can capacity
• Durable billet aluminum construction
• Helps reduce intake valve carbon buildup
• Captures oil vapor and crankcase contaminants
• Improves intake system cleanliness
• Includes mounting hardware and hoses
• Leak-resistant sealed design
• Easy drain and maintenance access

[Note]:It’s endorsed to test whether or not the oil separator wishes cleaning after driving 500 to 1000 miles.

Benefits for Direct Injection Engines

Direct injection engines do not wash intake valves with fuel like older port-injected systems. This allows oil vapor deposits to accumulate over time, especially under towing, aggressive driving, or high-mileage conditions.

An oil catch can helps reduce:

• Carbon buildup
• Oil contamination inside intake piping
• Detonation risks from oil vapor
• Sludge accumulation
• Reduced airflow efficiency

Basically, it helps your intake valves avoid becoming charcoal briquettes.

[Function]:The fine mesh aluminum clear out captures fine oil vapor, helping to increase engine life and keep it running smoothly and cleanly.

Great for Daily Driving and Towing

Whether your Silverado is a daily commuter, tow rig, family hauler, or lifted weekend truck, reducing oil contamination helps support cleaner engine operation over the long term. This is especially useful for vehicles frequently towing, hauling, or operating under high load conditions.

Which describes approximately 97% of trucks after somebody installs oversized wheels.

[Easy installation]:Equipped with the specified hoses, custom brackets and fittings for direct replacement. Including installation instructions.

Clean Installation and OEM-Style Fitment

The EVIL ENERGY catch can system is designed for a straightforward installation using vehicle-specific mounting points and included hardware. The compact design integrates cleanly into the engine bay while maintaining easy serviceability for draining collected oil residue.

Unlike universal kits that leave you fabricating brackets like you’re auditioning for a welding competition.

Why Choose EVIL ENERGY?

EVIL ENERGY continues to provide affordable and reliable performance solutions for modern trucks, performance vehicles, and custom builds.
