The Complete Guide to CCV Filters for Cummins 6.7 and LML EGR Delete

For performance enthusiasts and truck owners, it’s crucial to understand the modifications they’re considering. Two popular options are installing a CCV (Crankcase Ventilation) filter on Cummins 6.7 engines and performing an EGR (Exhaust Gas Recirculation) delete on LML Duramax engines. This guide provides comprehensive information on these modifications, their benefits, and installation tips, empowering you to make informed decisions for your vehicle.

Understanding CCV Filters for Cummins 6.7

What is a CCV Filter?

A CCV filter Cummins 6.7 is designed to capture and remove oil vapors and other contaminants from the crankcase ventilation system before reintroducing them into the engine’s intake. This helps maintain cleaner air intake and improves overall engine performance.

Benefits of Installing a CCV Filter on a Cummins 6.7

1. Reduced Oil Contamination: By filtering out oil vapors, the CCV filter keeps the intake system cleaner, reducing the risk of oil buildup on the intercooler and intake valves.
2. Improved Engine Efficiency: A cleaner intake system ensures better airflow and more efficient combustion, improving engine performance and fuel economy.
3. Extended Engine Life: Reducing oil contamination in the intake system helps prevent engine wear and tear, extending the engine’s overall life.
4. Lower Maintenance Costs: A cleaner engine means fewer maintenance issues and longer intervals between required servicing.

Types of CCV Filters

• Oil Separators: These devices separate oil particles from the crankcase gases and return the oil to the crankcase.
• Catch Cans: These containers collect oil and moisture from the crankcase gases, preventing them from entering the intake system.
• Breathers: These filters allow crankcase gases to vent to the atmosphere or a catch can, avoiding recirculation into the intake system.

Choosing the Right CCV Filter for Your Cummins 6.7

• Compatibility: Ensure the CCV filter is specifically designed for the Cummins 6.7 engine.
• Quality: Opt for high-quality filters from reputable brands to ensure durability and effective performance.
• Ease of Installation: Look for kits with all necessary hardware and clear installation instructions.
• Maintenance: Consider the ease of maintenance, such as how often the filter needs to be cleaned or replaced.

Installation Tips for CCV Filters

1. Preparation: Gather all tools and parts needed for the installation. Read through the instructions carefully before starting.
2. Locate the CCV System: Identify the location of the crankcase ventilation system on your Cummins 6.7 engine.
3. Install the Filter: Follow the manufacturer’s instructions to install the CCV filter. Ensure all connections are secure and there are no leaks.
4. Check for Leaks: After installation, start the engine and check for any oil or air leaks around the filter and connections.
5. Regular Maintenance: Periodically check and clean the filter to maintain optimal performance.

LML EGR Delete

What is an EGR Delete?

An EGR delete involves removing or turning off a vehicle’s Exhaust Gas Recirculation system. The EGR system recirculates some exhaust gases back into the ENG intake to reduce nitrogen oxide (NOx) emissions. However, this can lead to reduced performance and potential engine issues.

Benefits of an EGR Delete on an LML Duramax

1. Improved Performance: Removing the EGR system eliminates the recirculation of exhaust gases, leading to better combustion and increased power output.
2. Enhanced Fuel Efficiency: With no exhaust gases being recirculated, the engine operates more efficiently, often resulting in improved fuel economy.
3. Reduced Soot and Carbon Buildup: Eliminating the EGR system prevents soot and carbon deposits from accumulating in the intake manifold and valves, reducing maintenance needs.
4. Lower Engine Temperatures: Without the EGR system, the engine can run cooler, reducing the risk of overheating and related issues.

Types of EGR Delete Kits

• Complete EGR Delete Kits: These kits include all components needed to remove the EGR system, including block-off plates and necessary hardware.
• Partial EGR Delete Kits: These kits turn off the EGR valve but may leave some components in place, such as the cooler.
• EGR Cooler Delete Kits: These kits target the EGR cooler, eliminating it from the system while retaining the EGR valve.

Choosing the Right EGR Delete Kit for Your LML Duramax

• Compatibility: Ensure the EGR delete kit is specifically designed for the LML Duramax engine.
• Quality: Opt for kits made from high-quality materials to ensure durability and effective performance.
• Emissions Regulations: Be aware of local emissions laws and regulations, as EGR deletes are illegal in some areas and can affect emissions testing.
• Ease of Installation: Look for kits with detailed instructions and all necessary hardware.

Installation Tips for EGR Delete Kits

1. Preparation: Gather all tools and parts needed for the installation. Review the instructions thoroughly before beginning.
2. Safety First: Disconnect the battery and ensure the engine is excellent before starting the installation.
3. Remove EGR Components: Follow the instructions to carefully remove the EGR valve, cooler, and related components.
4. Install Block-Off Plates: Install the kit’s block-off plates and other components, ensuring all connections are secure.
5. Check for Leaks: After installation, start the engine and check for any exhaust or coolant leaks around the delete kit components.
6. Reprogramming: Sometimes, you may need to reprogram the engine’s ECU to ensure it operates correctly without the EGR system.

Conclusion

By installing a CCV filter on a Cummins 6.7 engine and performing an LML EGR delete on an LML Duramax, you can significantly enhance your vehicle’s performance, reliability, and longevity. A CCV filter helps keep the intake system clean and reduces oil contamination, while an EGR delete improves engine efficiency and power output and reduces maintenance needs. These modifications are not just about making changes, but about improving your vehicle’s performance and lifespan.

When selecting and installing these modifications, you have the power to choose high-quality components, ensure compatibility with your vehicle, and follow the manufacturer’s installation instructions carefully. By doing so, you can confidently enjoy the benefits of a cleaner, more efficient, and powerful engine.

Whether you’re aiming to elevate your truck’s performance for daily driving or gear it up for heavy-duty use, these modifications can bring about significant improvements and transform your driving experience. Always consider local regulations and the potential impact on emissions testing before performing an EGR delete, and consult with a professional if you’re unsure about the installation process.
