What Are the Benefits of a CCV Reroute on a 6.7L Cummins?

The 6.7L Cummins engine has earned its reputation as one of the most durable and high-performing diesel platforms available on the market. Its widespread use in heavy-duty Ram trucks has made it a staple among fleet operators, towing professionals, and performance enthusiasts. While its core mechanical architecture is robust, certain emissions-related subsystems—such as the factory Crankcase Ventilation (CCV) system—pose long-term risks to engine efficiency, cleanliness, and operational stability. One often overlooked modification that has a measurable impact on the 6.7L Cummins is the CCV reroute. While not as attention-grabbing as performance tuners or turbo upgrades, the rerouting of crankcase gases offers tangible, long-term benefits that directly affect engine longevity and operational precision. This article explores the intricate role of the CCV system, the limitations of its stock configuration, and the multi-dimensional advantages of a properly engineered reroute. Understanding the Function of the CCV System The CCV system, or Crankcase Ventilation system, is designed to manage the blow-by gases generated during the combustion cycle. As pressure builds within the crankcase due to minor combustion leakage past piston rings, it becomes necessary to vent these gases to maintain pressure equilibrium and prevent oil seal damage. In the stock 6.7L Cummins configuration, these crankcase gases—laden with oil mist and unburned hydrocarbons—are rerouted back into the intake tract. This method is implemented primarily for emissions control, as it allows the vapors to be reburned during combustion. However, while effective for meeting EPA regulations, this solution introduces a host of mechanical inefficiencies and contamination risks. Hidden Consequences of Recirculating Blow-By Gases The gases expelled from the crankcase are not inert. They are a complex mixture of oil vapor, fuel residues, combustion byproducts, and moisture. When these elements are routed back into the intake system, several issues begin to manifest: Oil Film Accumulation: Thin layers of oil coat the intake piping, throttle valve, and intercooler. This not only restricts airflow but also creates a sticky substrate for dust and soot particles to adhere to. Carbon Build-Up: In engines that also utilize an Exhaust Gas Recirculation (EGR) system, the combination of soot and oil mist leads to hardened carbon buildup. This drastically reduces volumetric efficiency and can choke airflow through the intake manifold. Sensor Contamination: Mass airflow sensors, MAP sensors, and throttle actuators are prone to failure when subjected to prolonged oil vapor exposure. Turbo Efficiency Loss: The turbocharger’s compressor wheel is particularly sensitive to oil vapor. Coating the fins with residue affects balance, spool rate, and long-term bearing health. While these consequences do not immediately disable the engine, their cumulative effect is a gradual but persistent degradation in performance, fuel economy, and reliability. How a CCV Reroute Solves These Issues A CCV reroute addresses the above concerns by redirecting crankcase gases away from the intake system and venting them through a separate, filtered outlet—often externally. This modification, though conceptually simple, has profound effects on engine cleanliness and stability. 1. Preserves Intake System Integrity The removal of oil-laden gases from the intake pathway ensures that no film or residue builds up over time. This helps maintain consistent airflow velocity, preserve sensor accuracy, and prevent premature failure of throttle bodies or EGR components. In practical terms, the engine breathes cleaner air, combustion is more stable, and the intake components remain cleaner even after tens of thousands of miles. 2. Reduces Turbocharger Contamination By preventing oil vapor from reaching the turbo inlet, a CCV reroute safeguards one of the engine’s most expensive and sensitive components. A clean compressor wheel maintains its aerodynamic properties, ensuring that turbo boost levels remain consistent and efficient. This is particularly crucial for engines subjected to high-load applications like towing or high-altitude driving. 3. Lowers Maintenance Costs and Intervals Contaminated intercoolers, fouled sensors, and EGR-related service are common and costly. A CCV reroute significantly delays, and in many cases eliminates, the need for such service. This translates to longer intervals between deep cleanings, fewer diagnostic issues, and more predictable maintenance planning for owners. 4. Improves Engine Longevity Through Cleaner Combustion Cleaner intake air leads to more complete combustion, especially under high cylinder pressures. The removal of oil mist eliminates the risk of pre-ignition caused by volatile hydrocarbons entering the combustion chamber. Over time, this helps preserve piston ring sealing integrity, cylinder wall condition, and oil quality—each of which contributes to engine life. 5. Minimizes Regeneration Frequency in DPF-Equipped Engines Though indirect, one valuable benefit of a CCV reroute is the reduction in particulate matter entering the exhaust system. When oil is burned alongside diesel fuel due to crankcase vapor recirculation, it produces more soot, which accelerates the clogging of the diesel particulate filter (DPF). Cleaner combustion means fewer regeneration cycles and extended DPF service intervals.

What Does a CCV Reroute Do?

Modern diesel engines are marvels of power, durability, and engineering efficiency. However, as emissions regulations have evolved, so too have the systems designed to meet these increasingly strict environmental standards. One such system is the Crankcase Ventilation (CCV) system, which plays a crucial role in managing internal engine pressure and emissions. Over time, however, this system can contribute to unwanted engine complications that reduce performance, increase maintenance, and affect long-term reliability. As a result, many diesel owners consider installing a CCV reroute as a practical upgrade. This article explores what a CCV reroute does, why it is often installed, and how it benefits diesel engines. Understanding the CCV System in Diesel Engines The Crankcase Ventilation (CCV) system is designed to relieve internal pressure caused by combustion gases that leak past the piston rings and enter the crankcase. These gases, commonly referred to as blow-by gases, are composed of air, unburned fuel, water vapor, and oil mist. Left unchecked, these gases would build up inside the engine and could cause seals to fail or gaskets to leak. To manage this, the CCV system reroutes these gases from the crankcase back into the intake system, where they are re-burned in the combustion chamber. While this reduces hydrocarbon emissions and aligns with federal regulations, it introduces oil vapors and contaminants directly into the engine’s intake tract, leading to several performance and maintenance concerns over time. What Is a CCV Reroute? A CCV reroute modifies the factory crankcase ventilation pathway. Instead of routing the blow-by gases back into the intake system, the CCV reroute redirects them to a separate venting location—often to the atmosphere or through a catch can system. This redirection prevents oil vapors from re-entering the intake manifold and mixing with fuel and air during combustion. The result is a cleaner intake system, reduced carbon buildup, and better overall airflow to the engine. The reroute can be installed using a series of hoses, fittings, and often a sealed filter or catch can that collects the oil vapor instead of allowing it to recirculate. Key Benefits of a CCV Reroute Installing a CCV reroute offers a wide range of advantages, especially for diesel trucks used in demanding applications such as towing, hauling, or performance modifications. Below are the most significant benefits associated with rerouting the CCV system. 1. Cleaner Intake System One of the most immediate and visible benefits of a CCV reroute is the dramatic reduction in oil contamination within the intake manifold and intercooler system. When oil vapor is introduced into the intake, it sticks to internal surfaces and combines with soot from the Exhaust Gas Recirculation (EGR) system. This creates a thick, sticky sludge that coats intake runners, turbocharger fins, and charge pipes. By redirecting oil-laden vapors away from the intake, a CCV reroute helps maintain cleaner intake components, which promotes better airflow and more efficient combustion. 2. Reduced Turbocharger Contamination Turbochargers rely on precise air dynamics and extremely tight tolerances. When oil vapors enter the intake and pass through the turbocharger, they can create residue on the turbine and compressor wheels. Over time, this buildup restricts the turbo’s efficiency, slows spool-up, and may lead to premature bearing wear or seal failure. A CCV reroute helps reduce these issues by preventing oil vapor from ever reaching the turbo, protecting this critical component and extending its service life. 3. Improved Engine Performance and Efficiency Cleaner air entering the combustion chamber leads to more consistent combustion, which enhances throttle response and power output. Additionally, with fewer contaminants introduced into the intake system, the engine management system can maintain optimal air-to-fuel ratios, promoting better fuel economy and overall drivability. While the performance gains from a CCV reroute alone may not be drastic, they become especially important when paired with other modifications such as intake upgrades, exhaust modifications, or tuning. 4. Extended Engine Life Oil mist and combustion byproducts recirculated into the intake not only lead to carbon buildup but can also cause damage to sensors and intake valves. Over time, the contaminated intake environment may lead to poor sensor readings, misfires, and even intake valve sticking. A rerouted CCV system mitigates these risks by ensuring that only clean air enters the intake tract, which contributes to smoother engine operation and longer service intervals. 5. Easier Maintenance and Reduced Downtime Cleaning out the intake system, turbocharger, or intercooler due to oil sludge buildup is time-consuming and expensive. Many diesel truck owners who do not address the root cause of this contamination find themselves performing this cleaning multiple times throughout the truck’s life. A CCV reroute greatly reduces the rate of oil vapor accumulation in these components. In many cases, owners who reroute their CCV system will not need to clean their intake or intercooler as frequently, leading to lower maintenance costs and more uptime on the road. Common Applications and Use Cases CCV reroutes are especially popular among diesel owners who use their trucks for high-load applications. These include: Heavy towing of trailers or equipment Off-road driving in dusty environments Performance or racing applications Long-distance hauling where engine longevity is critical In all of these cases, keeping the intake system clean and the turbocharger operating efficiently provides tangible benefits.

Everything You Need to Know About the 6.0 Powerstroke EGR Delete Kit

Upgrade your 6.0L Powerstroke with an EGR delete kit to boost performance, reduce engine temps, and prevent common EGR system failures

Why You Need the 6.7 Cummins EGR Delete Kit？

The 6.7L Cummins engine has long been recognized for its raw power, durability, and remarkable towing capacity. It has earned its place among the top choices for diesel truck owners, particularly those who demand performance under pressure. However, like many modern diesel engines, the 6.7L Cummins is equipped with emissions control systems that, although designed to reduce environmental impact, can inadvertently limit the engine’s true potential and increase long-term maintenance costs. Among these emissions systems, the Exhaust Gas Recirculation (EGR) system plays a central role. While intended to lower nitrogen oxide (NOx) emissions by rerouting a portion of exhaust gases back into the combustion chamber, the EGR system introduces a variety of performance and reliability challenges. For many diesel owners—particularly those who use their trucks for off-road, agricultural, or performance-based applications—removing the EGR system has become a practical and proven strategy for engine optimization. In this article, we explore in detail why deleting the EGR system is beneficial to your 6.7L Cummins engine and why the DynoVox EGR Delete Kit is a trusted solution for achieving long-term engine reliability, increased power output, and reduced operational costs. The Function of the EGR System and Its Limitations The EGR system in the 6.7L Cummins engine is engineered to reintroduce a controlled amount of exhaust gas back into the engine’s intake manifold. This process helps reduce combustion temperatures and, as a result, limits the formation of NOx emissions. Although this may sound like a beneficial function from an environmental standpoint, it comes at a high mechanical cost. The exhaust gases reintroduced into the intake are not clean. They carry with them soot, unburned hydrocarbons, and carbon particulates. Over time, this leads to significant carbon buildup within the intake manifold, EGR valve, and EGR cooler. These carbon deposits restrict airflow, reduce combustion efficiency, and can cause the engine to operate at suboptimal temperatures. In addition, the EGR cooler is highly prone to failure. Because it is continuously exposed to extreme temperature fluctuations, the internal metal components undergo thermal fatigue. Cracks or leaks in the EGR cooler can lead to coolant being introduced into the intake, which has the potential to cause hydrolock—a condition where the engine cylinders fill with liquid and are unable to compress, often resulting in catastrophic damage. Key Benefits of Removing the EGR System Removing the EGR system with a DynoVox EGR Delete Kit provides a host of tangible benefits that enhance the performance and longevity of the 6.7L Cummins engine. 1. Enhanced Engine Reliability By eliminating the EGR system, the risk of carbon buildup in the intake manifold and EGR cooler is entirely removed. The engine receives cleaner air, allowing for better combustion and more consistent operation. This significantly reduces the chances of valve sticking, sensor malfunctions, and premature gasket failures. Moreover, without the recurring stress caused by the EGR system, critical engine components are less likely to suffer from excessive wear and tear. This results in longer intervals between maintenance and less frequent part replacements—both of which are invaluable for vehicle owners who rely heavily on their diesel trucks for work or daily driving. 2. Improved Performance and Throttle Response With the EGR system out of the equation, the engine is free to operate with uninterrupted airflow and unimpeded combustion. This translates directly into improved throttle response and faster turbo spool-up. When combined with proper engine tuning, the removal of the EGR system can produce measurable increases in horsepower and torque. Many 6.7L Cummins owners who install an EGR delete kit report power gains in the range of 30 to 80 horsepower and up to 150 lb-ft of additional torque. These improvements are particularly valuable for heavy-duty applications such as towing, hill climbs, or hauling heavy loads over long distances. 3. Reduction in Exhaust Gas Temperatures (EGTs) The EGR system reduces combustion temperatures internally, but ironically causes higher exhaust gas temperatures due to impaired combustion efficiency. Deleting the EGR system restores proper combustion dynamics, which helps to lower EGTs significantly. This is especially beneficial during extended towing sessions or while driving in hot climates, where high EGTs can lead to premature engine wear or even failure. With lower EGTs, your engine is less stressed and better able to maintain optimal performance under extreme operating conditions. 4. Better Fuel Efficiency While not often the first concern for performance-minded diesel owners, improved fuel efficiency is a meaningful benefit of EGR deletion. Without the EGR system interfering with combustion, the engine can run at its most efficient settings. This optimization results in cleaner fuel burn, reduced soot production, and less fuel wasted during unnecessary EGR cycles. Many Cummins owners who opt for an EGR delete kit observe increases of 1 to 3 miles per gallon, especially when the engine is paired with a quality tuner that recalibrates the fuel maps for efficiency. Over the long term, these gains can represent substantial fuel cost savings, particularly for those who drive long distances or operate in commercial environments. 5. Reduced Long-Term Maintenance Costs One of the most compelling reasons to install a DynoVox EGR Delete Kit is the significant reduction in maintenance expenses. The EGR valve, cooler, and associated sensors are notorious for failure. Replacing these components—especially multiple times over the life of the truck—can cost thousands of dollars in parts and labor.
