Pros and Cons of 6.7 Powerstroke CCV Delete (2024 Update)

If you own a Ford Super Duty with a 6.7-liter Powerstroke engine, you may have heard about the possibility of performing a CCV (Crankcase Ventilation) delete. But what exactly does a CCV delete do for your 6.7 Powerstroke?

In short, a CCV delete removes or redirects the blow-by gases from the engine, reducing pressure in the intake system and potentially enhancing performance. This article will dive deep into the advantages and disadvantages of a 6.7 Powerstroke CCV delete, providing you with the essential insights to make an informed decision.

Understanding the 6.7 Powerstroke CCV System

The CCV system in a 6.7 Powerstroke is designed to collect and recirculate blow-by gases that escape from the engine, filtering out airborne particles, hydrocarbons, and oil vapors. This process helps maintain engine health by reducing oil contamination and ensuring compliance with emission regulations. However, the CCV system can also restrict airflow, negatively impacting engine performance over time.

CCV Delete vs. CCV Reroute: What’s the Difference?

There’s often confusion between a CCV delete and a CCV reroute. A CCV delete involves removing the CCV system entirely, allowing blow-by gases to vent directly into the atmosphere. In contrast, a CCV reroute uses a kit to redirect these gases to a different exit, often incorporating a catch can to trap oil droplets and contaminants before they can affect the intake system. While both modifications aim to improve performance and reduce intake contamination, a CCV reroute is generally considered more environmentally responsible since it doesn’t directly release pollutants into the atmosphere.

Benefits of CCV Reroute Kits

Using a CCV reroute kit offers several performance and maintenance benefits for your 6.7 Powerstroke engine:

• Improved Engine Performance: Removing the restrictive CCV system increases airflow to the engine, resulting in enhanced combustion efficiency and overall engine performance. This improvement is especially noticeable in high-performance diesel setups where every bit of airflow counts.
• Reduced Risk of Oil Contamination: By preventing oil droplets from re-entering the intake system, a CCV delete or reroute reduces oil buildup within the intake manifold and other components. This leads to a cleaner engine and potentially longer engine life with fewer maintenance issues caused by oil contamination.
• Additional Space in the Engine Bay: Removing or rerouting the CCV system frees up space under the hood, making room for other modifications or easing access for routine maintenance.

How Does a CCV Delete Kit Work?

A CCV delete kit works by rerouting the crankcase blow-by gases away from the intake system and into the atmosphere (in the case of a complete delete) or a catch can (in the case of a reroute). The goal is to prevent oil vapors and contaminants from entering the intake, thereby maintaining a cleaner air-fuel mixture and optimizing engine performance. This modification is straightforward but requires careful installation to avoid potential engine damage.

Pros and Cons of 6.7 Powerstroke CCV Delete

Pros:

• Enhanced Engine Performance: By removing the restrictive CCV system, you can increase airflow to the engine, resulting in better throttle response and improved overall performance. This is a significant advantage for those looking to optimize their engine's power output.
• Reduced Risk of Oil Contamination: With the CCV system removed or rerouted, the chance of oil re-entering the intake system and causing deposits is minimized. This benefit can lead to a longer engine life and less maintenance over time.
• More Room in the Engine Bay: Removing the CCV system opens up space under the hood, allowing easier access for other modifications or routine engine maintenance.

Cons:

• Legal and Environmental Concerns: The primary drawback of a CCV delete is the potential legal and environmental implications. The CCV system is designed to reduce emissions, and removing it can lead to increased pollution, which might violate emissions regulations in some areas. It’s crucial to consider local laws before proceeding with a CCV delete.
• Increased Oil Consumption: Without the CCV system, more oil vapors may escape into the atmosphere, potentially increasing overall oil consumption. This can result in higher long-term maintenance costs, as you might need to top off the engine oil more frequently.
• Risk of Engine Damage: If not installed correctly, a CCV delete can pose risks to your engine, such as improper ventilation leading to excessive crankcase pressure. Always ensure you use high-quality kits and have them installed by a professional to avoid potential issues.

Conclusion

A CCV delete can offer significant benefits for your 6.7 Powerstroke engine, including improved performance, reduced oil contamination, and more space in the engine bay. However, potential drawbacks like legal concerns, increased oil consumption, and the risk of engine damage need to be carefully weighed before proceeding.

Always consult a professional for installation and ensure that you choose high-quality components to avoid adverse effects on your engine’s health and longevity.

FAQs

Q1: What exactly does a CCV delete do on a 6.7 Powerstroke?
A1: A CCV delete removes the crankcase ventilation system, redirecting blow-by gases away from the intake system. This prevents oil vapors from re-entering the intake, potentially improving engine performance and reducing oil contamination.

Q2: Is a CCV delete legal for street use?
A2: The legality of a CCV delete varies by region. In some areas, modifying or removing emissions-related systems, including CCV, is illegal. Always check local regulations before proceeding with a CCV delete.

Q3: Does a CCV delete void my vehicle's warranty?
A3: Yes, a CCV delete can void your vehicle's warranty, especially if it leads to engine or emissions system issues. Consult your manufacturer or dealer before making this modification.

Q4: What are the main benefits of a CCV delete on a 6.7 Powerstroke?
A4: The main benefits include improved engine performance due to increased airflow, reduced risk of oil contamination in the intake system, and more space in the engine bay for other modifications or maintenance.

Q5: Can a CCV delete increase oil consumption?
A5: Yes, without the CCV system, more oil vapors may escape into the atmosphere, potentially leading to increased oil consumption. This could result in more frequent oil top-offs and higher maintenance costs.

Q6: What is the difference between a CCV delete and a CCV reroute?
A6: A CCV delete removes the entire CCV system, venting blow-by gases directly into the atmosphere. A CCV reroute, on the other hand, redirects these gases to a different exit, often using a catch can to trap oil droplets, making it a more environmentally friendly option.

Q7: Is an EGR delete worth it for my 6.7 Powerstroke?
A7: An EGR delete can improve engine performance and reduce soot buildup, but it also raises legal and environmental concerns. Additionally, removing the EGR system may void your vehicle's warranty and violate emissions regulations.

Q8: Can I perform a CCV delete and EGR delete together?
A8: Yes, many diesel enthusiasts choose to perform both modifications to enhance engine performance and reduce maintenance. However, be aware of the combined legal and warranty implications, as both are emissions-related systems.

Q9: How difficult is it to install a CCV delete kit on a 6.7 Powerstroke?
