OEM Maintenance of CCV Systems

As a vital emission control and engine protection component, regular maintenance of the CCV system is essential for maintaining vehicle performance and reliability. OEM-recommended maintenance includes periodic replacement of CCV filters and system cleaning to prevent oil mist and other contaminants from entering the engine's intake system, while ensuring effective emission control.

Why Choose CCV Modification

Reasons for opting for CCV modification may include:

  • Performance Enhancement
  • Problem Solving
  • Customization Needs

Methods of CCV Modification

Methods of CCV Modification Common methods of CCV modification include, but are not limited to:

1. CCV Delete

Method Description: CCV delete 6.7 powerstroke involves removing the original crankcase ventilation system. This includes dismantling ventilation pipes, valves, separators, and related sensors and fittings. Typically, reprogramming or modifying the vehicle's Electronic Control Unit (ECU) is necessary to avoid system fault codes or warnings. Suitable for extreme power output and rapid acceleration requirements, such as racing and truck racing competitions.


● Performance Enhancement: Removing the CCV system reduces oil mist contamination in the engine's intake ducts, improving ventilation efficiency and response speed.

● Simplified Maintenance: Reduces complexity and costs associated with maintenance, as there are no CCV filters requiring regular replacement or cleaning.

2. Enhanced CCV Filter

Method Description: This involves installing more efficient oil mist separators or filters on the existing CCV system. These new filters can more effectively capture oil mist particles emitted by the engine, reducing the likelihood of them entering the intake system. Suitable for applications requiring compliance with strict emission regulations and long-term use, such as commercial vehicles and long-haul transportation vehicles.


Improved Emission Control: Enhanced filters significantly improve oil mist separation efficiency, reducing oil residue in emissions and meeting stricter environmental requirements.

Engine Protection: Reduces corrosion and contamination inside the engine from oil mist particles, extending engine life and reliability.


Oil Mist Separation Efficiency Before Modification: 80%

Oil Mist Separation Efficiency After Modification: 95%

Potential Increase in Oil Mist Separation Efficiency: Up to 15%

3. Electronic Controlled CCV System

Method Description: Introduces an Electronic Control Unit (ECU) and sensors to monitor and adjust the CCV system intelligently. The ECU can dynamically adjust ventilation rates and oil mist separation efficiency based on driving conditions and engine load. Suitable for applications requiring dynamic adjustment and optimization of oil mist management, such as urban traffic vehicles and industrial machinery with frequent start-stop operations.


Dynamic Optimization: Optimizes ventilation rates according to actual operating conditions, improving fuel economy and engine efficiency. Automatic Protection: Monitors system pressure and temperature to operate safely within operational limits, reducing the risk of overheating or overpressure.

4. Custom CCV System

Method Description: Designs and installs customized CCV components and configurations based on specific vehicle or application requirements. This includes selecting high-performance materials and manufacturing processes to achieve optimal performance and reliability. Suitable for vehicles or equipment requiring specialized design and highly customized solutions, such as military vehicles, specialty vehicles, and advanced racing cars.


Precise Customization: Designs systems tailored to specific needs, ensuring optimal performance and cost-effectiveness.

Adaptation to Special Environments: Suitable for specialized vehicles or extreme working conditions, providing customized solutions.

Choosing the Most Suitable Modification Method

Consider the following factors when choosing the most suitable modification method:

1. Vehicle Type and Use

● Commercial Vehicles: Enhanced ccv filter 6.7 powerstroke may be preferable for vehicles requiring long-term operation or compliance with strict emission regulations, effectively reducing oil mist emissions and enhancing engine protection.

● Racing Vehicles: For vehicles on the track, such as racing cars or truck racing, CCV deletion may be more suitable as it improves engine response and combustion efficiency while minimizing system complexity.

● Specialty Vehicles: Customized CCV systems may be the best option for vehicles requiring specific designs and highly tailored performance solutions, such as military or specialty application vehicles.

2. Performance Requirements and Effect Evaluation

● Oil Mist Separation Efficiency: For those concerned with emission control and environmental standards, choosing an enhanced CCV filter or electronic controlled CCV system can improve oil mist separation efficiency, reducing oil mist particle emissions. However, if you choose 6.7 powerstroke crankcase filter delete kit (CCV delete 6.7 powerstroke + internal oil catch can+ oil pot), the oil mist separation efficiency may be up to 100%.

● Power Output and Fuel Economy: To enhance engine power output and fuel economy, CCV deletion or electronic controlled CCV systems can optimize ventilation efficiency and system response.

3. Cost-effectiveness and Maintenance Requirements — Enhanced CCV Filters vs. CCV Deletion

Initial Cost Comparison:

● Enhanced CCV Filters: Higher initial investment, but usually lower than CCV deletion, covering new filters and possible installation costs.

● CCV Deletion: Initial costs may be higher, covering system redesign and possible Electronic Control Unit (ECU) re-adjustment costs. Operating Cost Comparison:

● Enhanced CCV Filters: Operating costs are usually lower, requiring regular filter replacement and simple maintenance.

● CCV Deletion: Operating costs may be higher, requiring additional system monitoring and possible maintenance costs.

4. Maintenance Requirements — Custom CCV Systems vs. Electronic Controlled CCV Systems

● Custom CCV Systems: Lower maintenance frequency based on specific design requirements, but may require highly customized components and professional repairs.

● Electronic Controlled CCV Systems: May require more frequent system monitoring and maintenance, but due to intelligent control, it can reduce failure rates and improve maintenance efficiency.
