Discover what a CCV reroute does, its benefits, and installation tips for diesel engines like 6.7 Cummins, Powerstroke, and Duramax. Keep your engine clean and efficient.
What is a CCV Reroute?
The crankcase ventilation system (CCV) is an important exhaust device in the engine. Its main function is to guide the oil and exhaust gases in the crankcase and prevent excessive pressure from damaging the engine.
The original CCV system usually redirects these exhaust gases back to the intake manifold. Although this design can reduce emissions, it is easy to cause carbon deposits to form, affecting the performance and life of the engine.
CCV Reroute is a modification solution that redirects the crankcase exhaust gases to the atmosphere or oil collector instead of entering the intake system by rerouting the pipes. This method can effectively protect the engine, especially in high-load or off-road environments.
Why do you need CCV Reroute?
When exhaust gas and oil mist flow back into the intake system, sludge will form in the intake manifold and turbocharger. These deposits will gradually reduce the airflow path, resulting in reduced engine performance.
Long-term carbon deposits will also increase the wear of engine components and accelerate aging. This problem will be more obvious if your vehicle is often in high-load or off-road scenarios.
With CCV Reroute, you can avoid exhaust gas reflow, keep the intake system clean, and extend the life of the engine. This is especially important for those who often use their vehicles in harsh environments.
Main Benefits of CCV Reroute
Reduce Carbon Deposits
CCV Reroute can effectively prevent oil and gas from entering the intake tract, greatly reducing the formation of carbon deposits, thereby improving engine efficiency.
Protect the engine
Protect the turbocharger and other key components by rerouting the pipes, extending their service life.
Enhance off-road performance
CCV Reroute can provide more stable engine performance in off-road or high-load conditions.
Reduce maintenance costs
You will no longer need to clean the intake manifold frequently, which can save a maintenance cost in the long run.
How to install CCV Reroute? (Taking RAM 6.7L Cummins as an example)
Hey, today we will talk about how to install CCV Reroute on your RAM 6.7L Cummins. This is a simple and practical modification, which can not only increase the life of the engine, but also reduce the problem of carbon deposits. If you have good hands-on ability, you can do it by DIY. Of course, there are still some places to pay attention to.
Step 1: Locate the crankcase ventilation system
After opening the hood, look directly at the top of the engine, and you will find the plastic cover - it is covered on the valve cover, and the crankcase ventilation device is inside. This is where we want to change.
Note that this position is close to the turbocharger, where the temperature is relatively high. Therefore, when installing the hose later, be sure to avoid the hose from contacting the high-temperature area.
Step 2: Remove the original CCV device
Remove the plastic cover (that is, the original CCV component) from the valve cover. You will see two interfaces:
One is the exhaust outlet, which is used to guide the crankcase gas.
The other is the oil return port, which returns the excess oil to the engine.
Be careful when disassembling, especially the pipe joints. Don't use too much force to damage the joints. If there is oil stain, clean it with a cloth, and the subsequent installation will be more sealed.
Step 3: Install the Reroute Kit
Take out your CCV Reroute Kit, and let's install the small parts first:
Close the oil return port: This is a plug with an O-ring, press it directly into the oil return port of the valve cover, tighten it, and ensure that there is no leakage.
Connect the ventilation hose: Connect the silicone hose that comes with the kit to the exhaust outlet. This silicone hose is very oil-resistant. Don't use ordinary rubber hoses, otherwise it will be corroded by oil and gas over time.
Then, it's time to wire. We usually lead the hose along the side of the engine to the bottom of the car. Remember to fix it with a cable tie to prevent the hose from shaking or being worn.
Step 4: Test and adjust
After everything is installed, start the engine and listen carefully for any leaks. Touch the pipe joint with your hand to feel whether there is any exhaust gas leakage. If you find a leak, tighten the joint or readjust the hose position.
For RAM Cummins, the distance between the turbocharger and the hose must be sufficient. Too close will cause the hose to deform due to heat or even damage.
Special reminder
Oil collector optional:
If your car often runs high-load conditions, such as pulling heavy goods or off-roading, it is recommended to add an oil collector. It can filter out the oil mist in the exhaust gas and avoid dripping oil everywhere under the car.
Legal issues:
CCV Reroute is usually marked as "Off-Road Use Only". If your car runs on public roads, remember to check local regulations to avoid problems.
Last point: Be patient
Although the entire installation is not complicated, details determine success or failure. Especially the hose routing and interface sealing, these small places must not be careless.
After installation, you will find that the engine runs smoother and the cleanliness can be significantly improved. In the long run, this is a very cost-effective modification!
I hope these tips are helpful to you, give it a try! If you have any questions, remember to consult a professional or check the kit manual at any time.
Is CCV Reroute compliant?
In the United States, most CCV Reroute kits are labeled "Off-Road Use Only". This means that they are not suitable for public road vehicles, especially under strict emission regulations.
To ensure legality and environmental responsibility, you need to understand and comply with relevant laws and regulations. For example, the EPA (U.S. Environmental Protection Agency) has very strict regulations on vehicle emission systems. If your vehicle needs to be driven on public roads, please choose the modification plan carefully.

- Sierra Club: Clean Transportation Initiative
By referring to these resources, you can have a clearer understanding of the relationship between CCV Reroute and emission regulations, and perform modifications under the premise of legality.
Conclusion
By installing CCV Reroute, you can protect the engine from carbon deposit problems while improving off-road performance and engine life. However, you need to make sure that the modification is legal and complies with environmental regulations.
Modification is not only a performance improvement, but also a commitment to environmental responsibility. If you plan to install CCV Reroute, please prepare in advance and enjoy the fun of modification within the legal range!
