EVIL ENERGY Air Oil Separator oil catch can for Chevy/GMC 5.3L & 6.2L — direct-fit, aluminum mesh, includes hoses & brackets

EVIL ENERGY Air Oil Separator is a direct-fit oil catch can system that captures crankcase oil vapors to help keep intake and PCV systems cleaner on 5.3L and 6.2L GM V8 engines.

This compact air oil separator is engineered for late-model GM full-size trucks and SUVs, designed to replace the factory PCV routing with a more effective oil vapor separation solution. It fits the specified Chevy, GMC and Cadillac 5.3L and 6.2L engines and arrives with the hoses, brackets and hardware needed for a straightforward installation. The unit uses a fine mesh aluminum element to condense and collect oil mist while allowing blow-by gases to return to the intake, helping reduce carbon buildup and maintain throttle body and intake cleanliness over time.

Will this fit my 2016 Chevy Silverado 5.3L or 6.2L?

Yes — the EVIL ENERGY separator is built to match factory PCV routing on many 2014–2018 Silverado and 2014–2018 GMC Sierra models with 5.3L and 6.2L engines. The kit includes vehicle-specific brackets and hose lengths to simplify installation.

• Compatible model years and engine sizes included in kit description
• Custom brackets and fittings for direct replacement
• Pre-cut hoses to match factory routing and minimize trimming

How does this separator help engine cleanliness and performance?

The separator traps oil droplets and fine vapors before they re-enter the intake tract, reducing oil deposits on the throttle body and intake valves. This lowers the rate of carbon buildup and keeps sensors and intake components operating closer to factory condition.

• Fine mesh aluminum element captures microscopic oil mist
• Measured venting returns gases while retaining condensed oil
• Limits oil contamination of intake, throttle, and sensors

Is installation difficult and what maintenance does it need?

Installation is intended to be user-friendly; the kit ships with the necessary hoses, a mounting bracket and fittings plus written instructions. Maintenance is minimal: periodic checks and emptying or cleaning of the separator are recommended to keep it working efficiently.

• Includes step-by-step installation instructions
• Typically mounted on the PCV side for best vapor capture
• Inspect and clean every ~500–1,000 miles depending on driving conditions

What materials and quality features does the unit offer?

The can and internal filter use durable materials designed for engine bay conditions, resisting corrosion and thermal stress. Its construction balances efficient oil separation with reliable long-term operation under normal vehicle use.

• Aluminum fine-mesh filter element for effective vapor capture
• Robust canister and hardware suitable for engine bay temperatures
• Designed for repeat maintenance without replacing the housing

Who this product is for: drivers and enthusiasts who own compatible Chevy, GMC or Cadillac trucks and SUVs and want a simple, OEM-style upgrade to reduce crankcase oil vapors entering the intake. It's a practical choice for anyone looking to preserve intake cleanliness, lower long-term throttle and valve deposits, and maintain engine bay tidiness with an easy-to-install, serviceable separator.
