You remove the oil film in the intercooler pipes, reassemble the system, and a couple of weeks later, the oil film returns. This is all too common for 6.7 Powerstroke owners.
Diesel engines are highly sophisticated these days, but with that sophistication comes complications. A major issue is oil vapor re-circulation through the intake system, via the crankcase ventilation (CCV) system.
That is where CCV modifications come into play.
CCV deletes are back in fashion in 2026, but this time for a different reason. It’s not just a performance modification anymore. It’s a move towards better vehicle maintenance and engine longevity. Knowing what’s changed is important when considering this upgrade for your truck
What is a CCV delete?
A CCV delete redirects crankcase gases away from the intake system, preventing oil dilution, and keeping engine parts cleaner.
How a CCV Delete 6.7 Powerstroke Works
A crankcase ventilation system recycles blow by gases to the intake. This is important for emissions control, but also allows oil vapor to enter into vital engine components.
The vapor eventually builds up in the intake piping, intercooler and turbo system. This can block the airflow and also lead to wear.
In high-tech diesel engines – like the 6.7 Powerstroke – that have higher boost and smaller tolerances, even small amounts of contamination can make a big difference.
A CCV reroute or delete system diverts the gases from the intake. They bypass the engine and are either vented or filtered out.
Owners have reported cleaner intercooler piping when using a CCV delete 6.7 powerstroke system. In extreme cases visible oil is cut by 40 to 60 percent.
That is increasingly important in today’s engines which are highly dependent on clean air for optimum performance
Why CCV Deletes Are Rapidly Trending in 2026
The increased popularity of CCV deletes is part of a trend in diesel truck ownership.
Owners are holding onto their trucks for longer – often over 200,000 miles. This places more emphasis on preventive maintenance over short-lived performance enhancements.
Meanwhile, social media has allowed for real-world knowledge sharing. Diesel forums, vlogs and clubs will often post before-and-after pictures of what happens when oil gets into various parts of the engine.
The other change is a change in focus. A couple of years ago, the focus was on horsepower. Now it is all about durability.
Owners want to be more pragmatic. Rather than just seek performance, they want to safeguard their engines and minimise problems.
This change in mindset is a major reason why CCV solutions are trending again.
What Has Changed Since Earlier CCV Delete Trends
CCV deletes have been around for a while, but they have changed.
Older setups tended to be simple and occasionally poorly designed. Rudimentary vents to the atmosphere disregarded system balance and long-term impacts.
These days, there are better choices. New reroute kits and catch cans offer greater control of oil vapor while allowing the crankcase to breathe.
We also have more knowledge of installation. Truck owners are now aware that improper installation can cause problems such as pressure imbalance or oil leaks.
Finally, many are now taking a more holistic approach to engine preservation. For instance, flow enhancements are combined with fuel system enhancements such as a cp4 disaster prevention kit to prevent disasters.
So, the current approach is holistic. It’s not about deleting a system but improving its overall function.
The Downsides People Are Talking About in 2026
While CCV deletes can be beneficial, there are some downsides to consider.
Legality is a major issue. Altering emissions systems can result in legal problems in some areas.
A frequently mentioned disadvantage is oil vapor odors. External venting can cause smells especially when idling or in a closed space.
Proper installation is crucial Suboptimal installation can affect crankcase pressure potentially causing leaks or performance issues.
Warranty considerations are another factor. Alterations to stock systems can impact warranties particularly with new vehicles.
These factors do not necessarily outweigh the advantages but they do underline the need to carefully consider your individual circumstances.
Is a CCV Delete Worth it for 2016 ?
It varies based on your truck is application and goals
If you have a high mileage truck frequently towing heavy loads or have a modified vehicle a CCV reroute can prevent excessive build up and damage to vital parts.
But for regular commuting in regions with stringent emissions laws a catch can system or maintenance can be more suitable.
To decide, consider the following
- How long you plan on owning your truck
- Where your priorities lie between reliability and compliance
- Your driving conditions and usage
The right system can provide significant benefits if it meets your requirements . It is important to find one that meets your needs.
Final Words
The popularity of CCV deletes in 2016 is a sign of a more savvy attitude to owning diesel trucks.
Diesel truck owners are more interested in performance efficiency and preserving key elements than short term benefits.
Many truck owners see installing a ccv delete 6.7 powerstroke system as more than a fad. It is about preventing buildup, keeping systems clean and promoting engine longevity.
But this is not the right choice for all. The right choice is one that considers the truck, your operating conditions and your goals.
Ultimately, the best upgrades are not the most common. They are the ones that make sense for your truck use.
FAQs
1. What’s a CCV delete?
It prevents the flow of crankcase gases to the intake manifold, reducing oil consumption in engine parts.
2. Will a CCV delete increase performance?
Not directly. It primarily aids in air flow and allows the engine to perform at a more consistent level.
3. Is a CCV delete legal?
This varies by state. In some locations, it might be illegal to change stock systems.
4. How can I avoid an entire CCV delete?
Catch cans and reroutes offer a middle ground without interfering with system stability.
5. Why are CCV deletes making a comeback?
To ensure long-term reliability, lower maintenance and engine protection.
