Frequently Asked Questions About L5P Duramax CCV Reroute Kits

What is a CCV reroute kit for the L5P Duramax?

A CCV reroute kit redirects crankcase ventilation gases away from the intake system on 2017-2024 L5P 6.6L Duramax engines. Instead of routing oily vapors through the turbo and intercooler, it vents them externally. This helps reduce oil film buildup in the intake tract, but does not add horsepower or improve fuel economy. These kits are mechanical and do not require tuning.

How does a CCV reroute kit work?

The factory CCV system sends blow-by gases into the intake for re-burning. A reroute kit intercepts that path and diverts the gases to a vent point outside the engine bay. This keeps the intercooler and boost tubes cleaner. No permanent modifications are needed, and installation is typically straightforward with basic hand tools.

Will these kits fit my 2018 L5P Duramax?

Yes, both kits in this collection are designed for 2017-2024 L5P 6.6L Duramax engines, including 2018 models. One kit is universal for all L5P-equipped trucks, while the other is specifically for Chevy Silverado 2500/3500. Always verify your engine code and vehicle model against the product page details before ordering.

What is the difference between the two kit options?

One kit is a universal CCV reroute that fits any 2017-2024 L5P Duramax regardless of the vehicle model. The second kit is tailored for Chevy Silverado 2500 and 3500 trucks, which may offer model-specific mounting or hose routing. Both accomplish the same crankcase vapor venting. Choose based on your truck's model and the installation details on the product page.

Are CCV reroute kits street legal?

These kits modify the emission control system and are intended for off-road use only. Federal and local laws regulate such modifications, and using them on public roads may not be compliant. Review your state and local regulations before purchasing. EGR Performance makes no claims regarding on-road legality.

Is the installation difficult?

Installation is generally straightforward and does not require permanent modifications. Most owners can complete it with common hand tools. However, specific steps vary by kit, so consult the product page for detailed instructions. If you are unsure about the process, contact our support team during business hours through the Contact Us page.

What comes in the kit?

The exact components vary per kit. Typically, you can expect the necessary hoses, fittings, and mounting hardware. For a complete list, refer to the individual product page. Do not use improvised parts, as proper sealing and heat resistance are critical for reliable operation. Always check the product images and description before purchase.

Does this kit require any tuning?

No, a CCV reroute is purely mechanical. It does not alter engine management, fuel mapping, or sensor signals. The system simply redirects vented gases, so no ECU tuning is needed. Your truck will run as normal. If you have other performance modifications, confirm compatibility with the product page support details.

What is the return policy for these kits?

Unused products may be returned within 45 days of delivery when the Return & Exchange Policy conditions are met. Return shipping responsibility depends on the reason for the return. Review the current policy and use the Contact Us page for assistance. Check the individual product page for any applicable warranty terms.
