Introduction
When shopping for a new car, you may have heard the term "CCV." But what does that mean, and more importantly, what does it do?
CCV stands for Charge Cooling Valve, and it's an important part of your engine. In this article, we'll break down what CCV is, what it does, and how it can benefit your vehicle.
What Is CCV?
CCV stands for crankcase ventilation, and it's an essential component of your diesel engine. The CCV system evacuates the blow-by gasses that escape from the engine cylinders and crankcase. These gasses are then burned off in the exhaust system.
Without the CCV system, these blow-by gasses would collect in the crankcase and cause damage to your engine. The CCV system keeps your engine running efficiently and helps to prevent expensive repairs.
How Does a CCV Filter Help?
A CCV Filter helps to clean the air that enters your engine. It does this by trapping the dirt, dust, and other particles that would otherwise clog up your engine and cause damage. This can be especially important for those who drive in dusty or polluted areas, as it can help keep your engine running smoothly.
Should You Delete or Reroute Your CCV?
- The jury's still out on whether or not you should delete or reroute your CCV, but the general consensus seems to be that rerouting is the way to go.
- There are pros and cons to both options, of course, but it ultimately comes down to what works best for you and your truck. If you're comfortable with deleting your CCV, then go for it! But if you're not sure how to do it or you're not comfortable with the process, then rerouting is a safer bet.
- No matter which option you choose, be sure to do your research first and make sure that you're following the correct instructions. There are a lot of online tutorials out there, but it's always best to consult an expert if you're not sure what to do.
Different Types of CCV Filters: Cummins 6.7 and Powerstroke 6.7
- When it comes to CCV filters, there are two types that are popular in the diesel world: Cummins 6.7 and Powerstroke 6.7. Both have their own set of pros and cons, so before deciding which one to choose you should consider your needs.
- For instance, while Cummins 6.7 is more affordable and reliable, the Powerstroke 6.7 is a bit more complex but offers better performance. It also has a smaller footprint, making it easier to install in tight areas.
- If you're looking for even more power and efficiency out of your CCV system, you can look into upgrading to a larger filter or even going with a ccv reroute or delete kit for an even bigger boost in airflow. However, these mods require some technical know-how and tools so understand the risks before considering them.
Benefits of a CCV Filter Reroute on Your Diesel Engine
- It may sound complicated, but rerouting your CCV filter is actually a simple process that can make a big impact on your engine. By moving the filter away from the engine, the truck will no longer be ingesting oil vapors from the crankcase. This reduces build-up in the air intake, resulting in improved performance and fuel economy.
- Rerouting can also reduce stress on your turbocharger by decreasing oil accumulation in it, which also helps cut down on maintenance costs. Many diesel owners have reported that after installing a reroute kit to move their CCV filter they have had smoother running engines with increased power.
- Additionally, because a CCV reroute diverts oil vapors away from the engine bay instead of simply filtering them, there is less strain on your engine’s oil filtration system and less need for frequent maintenance changes. This will help you save money over time since you won’t need to replace filters as often.
CCV reroute 6.6 duramax
- The Duramax 6.6L CCV Reroute Kit for 2011-2016 GM Duramax trucks is an easy to install kit that includes all necessary hoses and fittings to properly reroute the CCV away from the engine. This kit is designed to work with both factory and aftermarket exhaust systems.
- Installing this kit will help to prolong the life of your engine by preventing oil and water from entering the combustion chamber. This kit is a must have for any Duramax owner looking to get the most out of their truck.
Conclusion
So, there you have it: Everything you need to know about CCVs. As you can see, there are a lot of different ways to go about setting one up, so it’s important to do your research and find the option that works best for you and your truck. And, of course, always be sure to consult with a qualified mechanic if you have any questions or concerns.
FAQ
1. What is a CCV system, and why is it important?
The Crankcase Ventilation (CCV) system is designed to remove blow-by gases that escape from the combustion chamber into the crankcase. Without proper ventilation, pressure builds up inside the engine, which can lead to oil leaks, sludge buildup, reduced performance, or engine damage.
2. What are blow-by gases, and why do they need to be removed?
Blow-by gases are combustion gases that leak past the piston rings into the crankcase. These gases contain unburned fuel, oil vapor, and other contaminants. If not vented properly, they increase internal pressure and degrade the engine oil, seals, and overall performance.
3. What does a CCV filter do?
A CCV filter captures oil mist, vapor, and particulate matter from the blow-by gases before they’re rerouted or vented. This helps prevent buildup inside the intake manifold and protects turbochargers, EGR valves, and sensors from oil contamination.
4. What happens if I don’t replace the CCV filter?
An overused or clogged CCV filter can cause crankcase pressure to rise, which may lead to:
-
Oil leaks from seals or gaskets
-
Oil buildup inside the intake or turbocharger
-
Decreased engine performance and fuel efficiency
-
Possible blue smoke from the exhaust
5. How often should I replace the CCV filter?
It’s generally recommended to replace the CCV filter every 50,000 to 60,000 miles.
For vehicles under heavy load, frequent towing, or extreme temperatures, more frequent replacement (e.g. every 30,000 miles) may be necessary.
6. What is a CCV reroute, and what are its benefits?
A CCV reroute kit diverts blow-by gases away from the intake system and vents them externally or through a catch can. Benefits include:
-
Reduced intake system buildup
-
Cleaner turbo and intercooler components
-
Improved throttle response
-
Less oil dilution and longer oil life
7. What is a CCV delete, and is it recommended?
A CCV delete fully removes the factory CCV system and vents the crankcase gases directly, often for off-road or racing use.
However, this may not be legal in some areas and could lead to excessive oil vapor discharge. A reroute with a catch can is a more balanced, emissions-aware option for most users.
8. Which trucks commonly use CCV reroute kits?
CCV reroute kits are commonly used on diesel platforms like:
-
6.6L Duramax (especially 2011–2016 LML models)
-
6.7L Cummins (2007.5 and newer Ram trucks)
-
6.7L Power Stroke (2011+ Ford Super Duty)
Always select a kit that matches your truck’s year and engine model to ensure proper fitment.
9. Do I need special tools or skills to install a CCV reroute kit?
Most CCV reroute kits are designed for easy bolt-on installation using basic hand tools.
If you're unfamiliar with engine components or routing hoses, it's a good idea to have a professional mechanic perform the install to ensure proper sealing and hose routing.
10. Will a CCV reroute affect emissions compliance or inspections?
Yes. In some areas with strict emissions regulations (such as California), venting crankcase gases to the atmosphere may not be legal.
Always check local laws and regulations before performing a CCV reroute or delete.
11. Will a 2017 F-250 6.7L Power Stroke need tuning with a CCV reroute with an internal catch can?
No. Installing a CCV reroute kit with an internal catch can on a 2017 F-250 6.7L Power Stroke typically does not require tuning.
Since the modification doesn’t change fuel, air, or boost parameters, it’s considered a plug-and-play upgrade.
However, if combined with other performance mods (like EGR deletes or intake changes), tuning may be necessary to optimize performance or prevent codes.
