Understanding the 6.7L Cummins CCV ReRoute: Benefits, Installation & FAQs

If you own a 2007-2023 6.7L Cummins, you’ve probably heard about the CCV (Crankcase Ventilation) reroute—a popular upgrade for improving engine longevity and performance.

The factory CCV/PCV system recirculates crankcase gases back into the intake, which can lead to oil buildup in the turbo, intercooler, and intake manifold. A CCV reroute kit solves this problem by venting these gases away from critical engine components.

In this guide, we’ll cover:
 - What a CCV reroute does
 - Key benefits for your Cummins
 - Installation tips
 - FAQs about CCV rerouting

What Is a CCV/PCV Reroute Kit?

The Crankcase Ventilation (CCV) system (also called Positive Crankcase Ventilation or PCV) helps manage blow-by gases in your 6.7L Cummins. However, the stock setup dumps oily vapors back into the intake, leading to:

      - Carbon buildup in the turbo & intercooler

      - Reduced airflow & efficiency

      - Potential oil contamination in the intake

A CCV reroute kit redirects these gases away from the engine, either to the atmosphere (vented) or into an oil catch can.

Benefits of a CCV Reroute for Your 6.7L Cummins

1. Cleaner Turbo & Intercooler – Prevents oil sludge buildup, improving airflow and turbo efficiency.

2. Better Engine Performance – Reduces carbon deposits in the intake, helping maintain optimal combustion.

3. Longer Engine Life – Minimizes oil contamination in critical components.

4. Reduced Maintenance – Fewer clogs mean fewer cleanings and repairs.

Installation Guide: How to Reroute Your Cummins CCV System

Installing a CCV reroute kit is a straightforward DIY job. Here’s a quick overview:

Steps:

      - Locate the factory CCV hose (connected to the intake tube).

      - Remove the stock hose and replace it with the reroute kit’s components.

      - Secure the new vent tube (either to a catch can or vented to atmosphere).

      - Double-check connections to prevent leaks.

      - Start the engine and inspect for proper ventilation.

(For detailed instructions, refer to the kit’s manual.)

FAQs About the Cummins CCV Reroute

      - Catch can setups are usually a safer option for street use.

❓ Will a CCV reroute void my warranty?

      - Modifying emissions-related components could affect warranty coverage. Check with your dealer.

❓ Do I need a tune after installing a CCV reroute?

      - No tuning is required—this is a purely mechanical modification.

❓ Can I use an oil catch can with a CCV reroute?

      - Yes! Many kits support catch cans to further reduce oil vapors.
