CCV PCV ReRoute Delete Kit 2011-2016 LML 6.6L Duramax

Q1: How does this CCV kit achieve a sealed effect? Do I need to keep the original gasket?

A: The baffle plate included in the kit is equipped with a rubber gasket to ensure sealing performance. You can also choose to retain the original gasket for enhanced sealing. In fact, keeping the original gasket provides an extra compression layer, which helps reduce the risk of air or oil-vapor leaks caused by engine vibration and thermal expansion.

Q2: Will a CCV reroute affect fuel economy?

A: A Crankcase Ventilation (CCV) reroute can potentially improve fuel economy by keeping the intake system clean and boosting engine efficiency. Cleaner intake airflow reduces resistance during combustion, leading to small but noticeable improvements in fuel efficiency over time.

Q3: How can I improve the fuel economy of my Duramax engine?

A: Regular vehicle maintenance, use of high-quality fuel, maintenance of proper tire pressure, and installation of performance upgrades (such as a PCV valve delete kit) are all helpful. Additionally, keeping the air filter clean, using synthetic engine oil, and ensuring the intercooler system is free of oil-sludge clogs can further enhance engine efficiency.

Q4: Is this kit legal for street use?

A: No, this kit is for off-road/racing use only. Federal laws prohibit disabling emission control systems on public roads. It is intended exclusively for race, off-road, or high-performance applications where emission regulations do not apply. Street use may result in fines or failed emissions inspections.

Q5: Will a PCV valve delete kit help extend engine life?

A: Yes. By reducing carbon buildup and lowering engine load, it helps extend engine lifespan. Over time, this leads to a cleaner combustion chamber, healthier turbocharger operation, and reduced wear on intake valves and bearings.

Q6: What is CCV rerouting?

A: A Crankcase Ventilation (CCV) reroute diverts crankcase ventilation gases away from the intake system, preventing oil sludge and carbon deposits from accumulating in the intake manifold and intercooler. By venting these gases elsewhere or through an oil-air separator system, it minimizes carbon buildup, keeps the intercooler clean, and maintains consistent airflow for optimal engine performance.

Q7: Will this kit void my vehicle’s warranty?

A: Modifying emission-related systems like the crankcase ventilation system may void the manufacturer’s warranty. If you have concerns about warranty coverage, consult your dealership before installation. Some dealerships may overlook minor modifications, but others may deny warranty claims for engine-related issues if a CCV reroute is detected.

Q8: Can this kit be used on high-mileage engines?

A: Absolutely! This kit addresses common issues in high-mileage Duramax engines such as oil blow-by and intake manifold carbon buildup. In fact, older, more worn engines tend to benefit the most from CCV rerouting, as they typically produce higher levels of blow-by gases.

We are dedicated to delivering the auto parts you need to your door as efficiently as possible. As a professional supplier of diesel truck emission system accessories, DieselPerf continuously refines our shipping services to ensure reliable, timely delivery that meets your expectations for speed and security.

1. Shipping Address Guidelines

To minimize costs and ensure smooth delivery, follow these tips when providing your address:

• Accuracy: Double-check your shipping address for errors before placing an order.
• Residential vs. Business Classification: If your business operates from a residential location, it will be classified as a residential address, and delivery fees will be charged accordingly.
• Contact Information: Provide an accurate phone number. Carriers may need to reach you to verify delivery details—failure to do so could cause delays.

For Damaged/Missing Items

If you receive damaged items, incomplete orders, or suspect issues, take these stepsimmediately:

1. Clearly note the damage/missing items on the delivery receipt before signing.
2. Retain your copy of the delivery receipt.
3. Contact our customer service team within 2 business days (email: service@DieselPerf.com; phone: +13250131608/+85253810098).
4. Keep all damaged packaging materials for inspection.
5. Take photos of the damaged items and packaging to support your claim.

For Lost Shipments

In rare cases of lost shipments, we work directly with the carrier to locate your items. Carrier dock checks typically take2–7 business days. If found, delivery will proceed; if deemed lost, we will collaborate with you to find a satisfactory resolution (e.g., replacement or refund).
