Collection: CCV PCV Reroute Kit

Advantages of the SPETUNER CCV Reroute Kit

With premium materials and precise engineering, the SPETUNER CCV Reroute Kit delivers substantial benefits, keeping your diesel engine in peak condition:

Reduces Sludge Accumulation
In a diesel engine, oil vapor and impurities entering the intake system are a common issue, leading to stubborn sludge and carbon deposits. The SPETUNER CCV Reroute Kit prevents these oil vapors and contaminants from reaching the intake system, keeping it clean and enhancing combustion efficiency. With a cleaner intake, your engine runs smoother and more efficiently, maximizing fuel use and power output.

Optimizes Engine Performance
A clean intake system means better airflow, which directly improves combustion efficiency. For diesel vehicles that get used heavily, installing a CCV Reroute Kit makes an immediate difference in performance. You’ll notice the throttle is more responsive, and power delivery is more immediate, exactly what we diesel enthusiasts strive for. With every press of the pedal, you’ll feel the engine respond with seamless power.

Extends Component Life
When carbon buildup is minimized, wear on engine components is reduced. The SPETUNER CCV Reroute Kit helps protect the intake system and other engine components, extending their service life and lowering maintenance costs. In short, installing this kit means a more durable engine with lower upkeep.

Each SPETUNER CCV Reroute Kit is crafted from high-temperature-resistant materials that stand up to extreme conditions. No matter where you’re driving—on city streets or in harsh environments—SPETUNER’s CCV Reroute Kit will keep your diesel engine running smoothly, providing lasting durability and reliable performance.

Vehicle Compatibility Note

The SPETUNER CCV Reroute Kit is suitable for a wide range of diesel applications, including the 6.7 Cummins CCV filter replacement, 6.7 Powerstroke CCV reroute, and even CCV filter delete kits for performance or off-road setups. Whether you're maintaining a stock 6.7L Cummins or upgrading your Powerstroke, we offer options designed to fit perfectly and perform under pressure.

Why Diesel Owners Replace or Delete the CCV Filter

Many diesel truck owners, especially those with a 6.7 Cummins or Powerstroke, choose to delete or replace the factory CCV filter to prevent oil mist from re-entering the intake system. This modification not only reduces maintenance but also improves airflow and performance. Whether you're after a full CCV reroute or just a filter replacement, SPETUNER offers parts engineered for the demands of diesel enthusiasts.

FAQs：CCV Delete & Reroute – Everything You Need to Know

Q1: Can I vent my diesel CCV system to atmosphere legally?
A: Venting your CCV system to atmosphere is typically not legal for on-road use in most U.S. states due to EPA emissions regulations. However, for off-road, competition, or deleted builds, venting is a popular option to eliminate oil mist recirculation. Always verify your local emissions laws before installing an open CCV breather kit.

Q2: What are the symptoms of a clogged CCV filter on a 6.7 Cummins?
A: Common signs include increased crankcase pressure, oil residue around the filter housing, decreased throttle response, and even turbo seal leaks. On a 6.7L Cummins, when the CV52001 CCV filter becomes saturated, it often causes oil to blow past gaskets and into the intake. That’s when most owners switch to a CCV filter delete kit.

Q3: Does a CCV reroute kit improve fuel economy on a diesel truck?
A: While the kit alone doesn't boost horsepower, it reduces intake restriction and prevents oil mist from disrupting combustion. Cleaner airflow can lead to more stable fuel-air ratios, especially during towing or under load, which can translate to marginal fuel economy gains over time in high-mileage trucks.

Q4: Do I need a tune after installing a CCV delete kit?
A: No tune is required for most CCV delete or reroute kits, including those for 6.7 Cummins, Powerstroke, or Duramax engines. However, if you're already running a performance tune, combining it with a clean intake path from the CCV delete can enhance throttle response and lower EGTs.

Q5: What’s the difference between a diesel catch can and an open breather?
A: A diesel catch can system collects oil vapor and blow-by gases in a sealed container, ideal for street-driven or emissions-conscious builds. An open breather vents directly to atmosphere—better for off-road or race applications. Both are effective, but catch cans require periodic draining, while breathers offer a simpler install.

Q6: How much oil does a diesel catch can collect between oil changes?
A: On average, a catch can in a CCV delete system collects 3–6 ounces of oil every 3,000 to 5,000 miles, depending on engine wear, boost levels, and driving style. Towing-heavy or tuned trucks may see higher amounts. Regular inspection during oil changes is recommended.

Q7: Is deleting the CCV system safe for daily driving?
A: Yes—deleting or rerouting the CCV system is a proven reliability mod for diesel engines. As long as it's installed correctly and used within emissions-exempt conditions, it can help reduce intake sludge, extend turbo life, and minimize sensor fouling—especially on daily-driven 6.7L Powerstroke or Cummins trucks.

Q8: What size hose do I need for a CCV reroute kit installation?
A: Most diesel CCV reroute kits use 5/8" or 3/4" oil-resistant hose, often made from high-temp silicone or braided rubber. Kits from SPETUNER are pre-cut and fitted with correct diameters for direct bolt-on applications to Cummins, Powerstroke, and Duramax engines.

Q9: Will a CCV delete help reduce oil in my intercooler piping?
A: Absolutely. One of the top reasons to install a CCV delete is to prevent oil mist from entering the turbo and intercooler system. Many owners report noticeable reductions in oily residue inside boost pipes and charge air coolers, especially in tuned or high-mileage diesel trucks.

Q10: Can I install a CCV delete kit myself, or should I have a shop do it?
A: Most CCV reroute and delete kits are DIY-friendly and take about 1 to 1.5 hours to install with basic tools. However, on some platforms like the 6.4 Powerstroke, accessing the valve cover vent may require more advanced knowledge. If you’re not confident, a diesel performance shop can easily complete the install.
