Product Description
Dyno Diesels PCV/CCV Reroute Kit
w/ 8 ft Hose + Resonator Plug | 2004.5–2010 GM 6.6L Duramax (LLY / LBZ / LMM)
Cleaner Intake. Less Oil Film. Better Long-Term Reliability.
The Dyno Diesels PCV (CCV) Reroute Kit is designed to redirect crankcase vapors out of the intake tract, helping reduce the oil mist that commonly coats intercooler piping, turbo inlet components, and the charge-air cooler system on Duramax trucks. Factory routing sends these vapors back through the intake, which can contribute to oil buildup over time—especially on tuned or higher-mileage trucks.
This kit also includes a resonator plug, allowing you to eliminate the intake resonator opening for a cleaner, more secure intake setup.
Why Reroute the PCV/CCV on a Duramax
- Helps reduce oil contamination in the intake and CAC piping
- Promotes cleaner airflow and supports consistent long-term drivability
- Ideal for performance, towing, and daily-driver builds where keeping the intake path clean matters
What’s Included
Based on common top diesel kit configurations for this exact style, this package includes:
- (2) CNC-machined valve cover PCV fittings (typically black anodized aluminum)
- Viton O-rings for positive sealing
- PCV-to-intake block-off plug
- Resonator delete plug
- (1) 8 ft length of high-temp silicone hose (commonly 5/8" on this kit style)
- Hose clamps for secure routing

- 2007.5–2010 Duramax LMM
(6.6L Silverado/Sierra HD applications)
Installation Notes
- Straightforward install with basic hand tools

- Designed for a clean, professional under-hood finish
Dyno Diesels Theme
