What Does the CCV Reroute Kit Do on a Duramax?

Stock CCV systems recirculate oily blow-by gases back into your intake, leading to carbon deposits, reduced efficiency, and costly repairs.

On a reverse-level Duramax, this can clog your turbo and intercooler fast, especially under heavy towing or tuning. The hidden damage? Oil ingestion causes power loss, sensor failures, and skyrocketing maintenance bills.

Our LLY LBZ LMM LML L5P CCV upgrade vents blow-by pressure safely, keeps your intake tract spotless, and deletes the factory CCV box for a streamlined setup.

Benefits include reduced pollution in your intake, turbo protection, improved performance, lower costs, and optimized engine bay space for other mods.

Is a Duramax CCV Reroute Legal?

It depends on your location. In CARB states like California, venting to the atmosphere might not pass emissions—our kits are designed for off-road, racing, or agricultural use only.

Always check local laws before installing an LLY LBZ LMM LML L5P CCV delete or similar.

Frequently Asked Questions

Q: Does a Duramax CCV reroute void my warranty?

A: Installing a Duramax CCV reroute kit may potentially void parts of your factory warranty if it's considered an emissions-related modification, so always check with your dealer or manufacturer beforehand to confirm.

Q: Best catch can vs. CCV reroute for Duramax?

A: A catch can is ideal for capturing and separating oil vapors to keep your intake clean, while a full CCV reroute redirects blow-by gases entirely away from the intake; for optimal protection on a Duramax, combining both provides the best results over using just one.

Q: How often should I empty my catch can?

A: You should check and empty your catch can every 3,000 to 5,000 miles, or more frequently if you're towing heavy loads, driving in hot climates, or noticing faster buildup.

Q: Will rerouting my Duramax CCV improve fuel economy?

A: Yes, rerouting your Duramax CCV can improve fuel economy by maintaining a cleaner intake system, leading to more efficient combustion and reduced power loss from oil contamination.

Q: Is vent-to-atmosphere legal in my state?

A: Vent-to-atmosphere CCV systems are often not legal for street use in states with strict emissions regulations like California (under CARB rules), so verify your local laws—opt for closed-loop systems if compliance is required.
