Review WX Ccv Crank Case Vent Kit Dodge 6.7l 4500 fits CUMMINS 2500 3500 5500 2007–2018

The **WX Wenxi AIT25 CCV Crank Vent Kit** is a meticulously engineered aftermarket solution designed specifically for the high-performance demands of the **2007 2018 Dodge 6.7L Cummins diesel engines** found in the **2500, 3500, 4500, and 5500** series trucks. Engineered to address the critical function of crankcase ventilation (CCV), this kit ensures optimal oil and air circulation within the engine bay, preventing harmful blow-by gases from accumulating and reducing overall engine efficiency. The **AIT25** model stands out with its **high-flow, high-performance design**, featuring a **stainless steel construction** that resists corrosion, heat, and wear critical factors for the demanding conditions of a turbocharged diesel engine. Unlike generic or OEM replacements, this kit incorporates **precision-machined components**, including a **large-diameter intake hose** and a **reinforced crankcase breather**, which significantly enhance airflow while minimizing backpressure. This reduction in backpressure not only improves engine breathing but also helps maintain proper oil pressure and reduces the risk of sludge buildup, a common issue in high-mileage or heavily modified Cummins engines. The kit s **universal compatibility** with the 6.7L Cummins lineup ensures a seamless fit, requiring minimal modifications, and its **easy installation** makes it an ideal upgrade for both DIY enthusiasts and professional mechanics. Whether you re looking to **boost engine longevity, improve turbo performance, or mitigate oil consumption**, the **WX Wenxi AIT25 CCV Kit** delivers a robust, reliable solution that exceeds factory specifications. Built to withstand the rigors of heavy-duty towing, off-roading, or daily driving, this kit is a must-have for anyone seeking to preserve the integrity and performance of their Cummins-powered Dodge truck.

### **Pros and Cons of the WX Wenxi AIT25 CCV Crank Vent Kit for 2007 2018 Dodge 6.7L Cummins (2500 5500 HD Trucks)**

#### **Pros**

1. **Improved Engine Breathing and Performance**

The CCV (Crankcase Control Valve) system helps regulate crankcase pressure, reducing blow-by and improving engine efficiency. The AIT25 kit is designed to enhance airflow, which can lead to better throttle response, smoother idle, and improved power delivery especially noticeable under load.

2. **Reduced Oil Consumption and Blow-By**

The stock CCV system on older Cummins engines can wear out or become clogged, leading to increased oil consumption and crankcase pressure. The Wenxi kit features a high-flow, durable valve that helps mitigate these issues, reducing oil leaks and blow-by over time.

3. **Durability and Quality Materials**

Wenxi is known for producing high-quality aftermarket parts, and the AIT25 kit is built with precision-engineered components, including a stainless steel valve and reinforced housing. This reduces the likelihood of premature failure compared to OEM or cheaper aftermarket alternatives.

4. **Easy Installation**

The kit is designed for straightforward installation, requiring minimal modifications. It replaces the stock CCV assembly with a drop-in solution, making it accessible for DIY enthusiasts or shop mechanics without extensive Cummins experience.

5. **Compatibility with Turbocharged Applications**

The 6.7L Cummins is a turbocharged engine, and proper crankcase ventilation is critical for turbo performance. The AIT25 kit helps maintain optimal boost levels by reducing backpressure in the crankcase, which can be beneficial for turbocharged builds.

6. **Potential for Long-Term Reliability**

Since the kit addresses a common failure point in older Cummins engines, installing it early can prevent costly repairs down the line. Many users report reduced engine wear and extended component life after switching to a high-quality CCV system.

7. **Positive User Feedback**

Reviews from Cummins owners suggest that the Wenxi AIT25 kit outperforms stock and other aftermarket options in terms of durability and effectiveness. Many report noticeable improvements in engine smoothness and reduced oil consumption.

#### **Cons**

1. **Cost Relative to Stock Replacement**

While the Wenxi kit is more durable than OEM parts, it is still an aftermarket upgrade with a higher upfront cost compared to replacing a failed stock CCV assembly. For some, this may not justify the expense unless they are experiencing active issues.

2. **Potential for Overkill on Well-Maintained Engines**

If the stock CCV system is still functioning adequately (no leaks, minimal blow-by, and stable oil levels), installing this kit may not provide significant benefits. It s primarily beneficial for engines with existing crankcase ventilation problems.

3. **Installation Requires Attention to Detail**

While the kit is designed for ease of installation, improper sealing or misalignment during installation could lead to leaks or reduced performance. Users should follow the instructions carefully or consult a professional if unsure.

4. **Limited Warranty Compared to OEM**

Wenxi offers a warranty, but it may not match the lifetime or transferable warranty of some OEM parts. However, the durability of the kit often outweighs this concern for most owners.

5. **Compatibility with Modifications**

While the kit is designed for stock and lightly modified engines, extreme builds (e.g., high-boost applications) may require additional tuning or supporting modifications to fully realize the benefits of the CCV upgrade.

6. **Mixed Results on Oil Consumption in Some Cases**

While many users report reduced oil consumption, a small percentage note that the kit did not eliminate oil leaks entirely. This may depend on the root cause of the issue (e.g., piston rings, valve seals, or other internal wear).

7. **Availability and Lead Times**

As with many high-quality aftermarket parts, the Wenxi AIT25 kit may not always be in stock, requiring patience or ordering from specialty suppliers. This could delay installation if timing is a concern.

---

### **Conclusion**

The **WX Wenxi AIT25 CCV Crank Vent Kit** is a well-engineered, high-performance upgrade for the 2007 2018 Dodge 6.7L Cummins, particularly for trucks experiencing crankcase ventilation issues, oil consumption, or blow-by. Its primary advantages lie in improved engine breathing, reduced oil waste, and long-term reliability. For owners with stock or mildly modified engines showing signs of CCV failure, this kit is a worthwhile investment to prevent further damage and enhance performance.

However, if the stock system is still functioning well and the engine is well-maintained, the benefits may not justify the cost. In such cases, monitoring oil levels and listening for unusual crankcase pressure symptoms is advisable before upgrading.

For most Cummins enthusiasts, the **Wenxi AIT25 kit is recommended** as a proactive or reactive solution to CCV-related problems. It strikes a balance between performance gains, durability, and ease of installation, making it a strong choice for those looking to extend the life of their engine and improve its operation.

- **Install if:** You notice oil leaks, excessive blow-by, rough idle, or high oil consumption; or if you re performing a rebuild and want to future-proof the engine.

- **Avoid if:** The stock CCV is functioning fine, and you re not experiencing related symptoms.

- **Best for:** Cummins owners prioritizing longevity, performance, and reliability in their engine.

Details:

Package Included. 100% quality assurance tested, more responsive, less expensive, easier to install. Will come with everything you see in the picture. With the new 6.7L emissions systems they've switched to a CCV or Closed Crankcase Ventilation system.

If crankcase blow-by is higher than normal these gasses can also coat the inside of inter cooler which lowers its efficiency. This eliminates the oil buildup on turbo compressor and maintains inter cooler cleanliness. Material Color. Color: as picture.

This kit does retain the stock CCV filter. The Open Breather Kit converts the closed system back to an open breather. The CCV system dumps the crankcase gasses into your turbo inlet post air filter which causes an oily buildup on compressor wheel. For years Cummins has vented crankcase gasses to the atmosphere.
