Frequently Asked Questions
What is this CCV reroute / delete kit?
This is a CCV (Crankcase Ventilation) reroute and upgrade kit designed for 2017–2024 L5P 6.6L Duramax engines. It replaces the factory plastic CCV components with a more reliable aluminum-based system to improve durability and airflow control.
What problems does this kit solve?
The factory L5P CCV system is known to crack over time due to heat and plastic fatigue. This kit removes that weak point, prevents hot charge air and oil vapor from entering the intake, and helps keep the intake track clean.
How does this improve engine reliability?
By eliminating the factory CCV routing into the intake air horn, this kit prevents high-temperature air and oil mist from contaminating the intake system. Integrated differential drop devices help efficiently remove oil from the CCV supply line.
Does this affect oil filling or maintenance?
Yes — in a positive way. Removing the factory CCV component provides a safer and more convenient oil fill location at the front of the engine, while separating the CCV system from the oil fill port for improved safety.
What materials are used in this kit?
The kit is constructed from high-quality aluminum alloy and rubber components, offering superior heat resistance, durability, and long-term reliability compared to factory plastic parts.
Is this a direct bolt-on kit?
Yes — this CCV reroute kit is designed as a direct-fit upgrade for compatible L5P Duramax trucks. Professional installation is recommended for best results.
Which vehicles does this kit fit?
This kit fits the following vehicles equipped with the 6.6L L5P Duramax diesel engine:
• 2017–2024 GMC Sierra 2500 HD / 3500 HD
• 2017–2024 Chevrolet Silverado 2500 HD / 3500 HD
Note: Fits Crew Cab Short Bed and Crew Cab Long Bed models only.
Does NOT fit 3500/4500/5500 Cab & Chassis commercial trucks.
