What's a Cummins CCV Reroute kit ?
A Cummins CCV Reroute Kit is a crankcase ventilation system designed to redirect oil vapor and blow-by gases away from the factory intake system. From the factory, Cummins engines route crankcase vapors back into the intake, where oil mist can build up and contaminate the turbocharger, intercooler, and charge pipes.
Key Benefits of Installing a Cummins CCV Reroute kit
- Reliability: Stop CCV filter clogs to prevent seal-damaging crankcase pressure.
- Engine Longevity: Keep your intake and valves pristine by stopping oil buildup.
- Turbo Protection: Prevent oil vapor from coating and pitting your compressor wheel.
- Lower Maintenance: Eliminate the recurring cost of expensive factory CCV filters.
- Performance: Experience cleaner combustion and more consistent throttle response.
- Better Cooling: Ensure your intercooler stays oil-free for maximum heat exchange.

How to Install a Cummins CCV Reroute kit
Installing a Cummins CCV (Crankcase Ventilation) reroute kit redirects oil-laden crankcase vapors away from the turbo inlet and intake system. This helps reduce oil buildup in charge pipes, intercoolers, and intake manifolds.
Installation Steps
- Engine Bay Preparation: Allow the engine to cool and locate the factory CCV outlet, typically found on the valve cover or upper engine assembly depending on the Cummins generation.
- Factory CCV Hose Disconnection: The factory CCV hose routing crankcase vapors back into the turbo inlet or intake system is carefully disconnected, preventing oil mist recirculation.
- CCV Reroute Kit Installation: The CCV reroute hose, fittings, and filter** **are installed onto the factory CCV port. Kits may vent vapors to atmosphere or route them through a filtered system, depending on design and application.
- Hose Routing & Securing: The reroute hose is positioned away from heat sources and moving components, then secured using provided clamps or brackets to ensure proper clearance and long-term durability.
- Final Inspection & Verification: All connections are checked for secure fitment. The engine is started briefly to confirm proper crankcase ventilation and ensure no leaks or abnormal pressure buildup.
Note: Every EngineGo kit includes a comprehensive, model-specific guide to ensure your installation is seamless and your fitment is guaranteed.
