Review NISSAN Genuine Oe Tube breather

The **Nissan 17338-6GP0A Tube-Breather** is a precision-engineered component designed to maintain optimal engine performance and longevity in select Nissan vehicles by effectively managing crankcase pressure. This high-quality aftermarket part is crafted to replace the original equipment manufacturer (OEM) tube-breather, ensuring seamless compatibility with engines such as those found in the Nissan 3.5L V6 applications, including models like the Altima, Maxima, Murano, and Rogue. Engineered with a durable, corrosion-resistant material, this tube-breather features a robust design that prevents oil leaks, reduces carbon buildup, and minimizes the risk of engine fouling a common issue in vehicles with aging or poorly maintained breather systems. The component incorporates a precision-machined tube and a secure, leak-proof connection, allowing for efficient ventilation while filtering out contaminants that could otherwise infiltrate the engine bay. By maintaining proper crankcase pressure, this breather helps prevent oil from being forced into the intake system, which can lead to sluggish performance, reduced fuel efficiency, and potential damage to intake valves. Ideal for both original equipment replacement and performance-oriented upgrades, the Nissan 17338-6GP0A Tube-Breather is a straightforward yet critical component for preserving engine health and ensuring reliable operation over time. Its straightforward installation and long-term durability make it a cost-effective solution for vehicle owners seeking to maintain their engine s efficiency and extend its service life.

### **Pros and Cons of buying a Nissan 17338-6GP0A Tube-Breather**

The **Nissan 17338-6GP0A** is a tube-breather (also called a PCV valve or crankcase ventilation valve) used in certain Nissan engines, particularly those with the **QR25DE, VQ35DE, and other related models**. Below is a detailed analysis of its advantages and disadvantages.

---

### **Pros of buying a Nissan 17338-6GP0A Tube-Breather**

1. **OEM Quality and Compatibility**

- This is a genuine Nissan part, meaning it meets the manufacturer s specifications for fit, function, and durability. It is designed specifically for Nissan engines, reducing the risk of improper sizing or material issues.

- Works seamlessly with engines like the **QR25DE (e.g., Altima, Sentra, Maxima), VQ35DE (e.g., 350Z, Altima, Maxima), and others** that require this exact part number.

2. **Prevents Engine Contamination**

- The tube-breather (PCV system) helps vent harmful crankcase gases from the engine block to the intake manifold, preventing oil sludge buildup and reducing emissions. A faulty or clogged valve can lead to **oil leaks, reduced engine performance, or even engine damage** over time.

- Ensures proper crankcase ventilation, which is critical for maintaining engine cleanliness and longevity.

3. **Easy Installation and Replacement**

- The part is relatively simple to install typically involves removing the old valve and securing the new one in its place. No major modifications or additional tools are usually required.

- Many mechanics and DIYers find it straightforward to replace, making it a cost-effective maintenance item.

4. **Cost-Effective Maintenance**

- Compared to other engine components, the tube-breather is inexpensive. Replacing it as part of routine maintenance can prevent more expensive repairs down the line (e.g., oil leaks, valve train damage).

- Extends the life of the **PCV system**, reducing the need for frequent replacements of related components like hoses or seals.

5. **Improves Engine Performance and Efficiency**

- A functioning PCV valve ensures proper airflow, which can help maintain **optimal engine compression and fuel efficiency**. A clogged or failing valve can lead to **rough idling, reduced power, or increased emissions**.

- Helps keep the engine running smoothly by preventing excessive pressure buildup in the crankcase.

6. **Widely Available and Affordable**

- As an OEM part, it is readily available from **Nissan dealerships, auto parts stores (AutoZone, O Reilly, RockAuto), and online retailers (Amazon, eBay, RockAuto)**.

- Pricing is competitive, typically ranging from **$10 to $30**, depending on the source and whether it s new or refurbished.

7. **Prevents Emissions Issues**

- A failing PCV valve can cause the engine to fail **emissions tests** in regions with strict regulations. Replacing it ensures compliance and avoids potential fines or registration issues.

8. **Long-Term Reliability**

- Since it is a simple mechanical component with few moving parts, it is less prone to catastrophic failure compared to more complex engine parts. Regular replacement (every **30,000 50,000 miles**) helps maintain reliability.

---

### **Cons of buying a Nissan 17338-6GP0A Tube-Breather**

1. **Potential for Counterfeit or Low-Quality Parts**

- Some aftermarket or "OEM" parts sold online may be **counterfeit or of inferior quality**, leading to premature failure. Buyers must verify the seller s reputation and part authenticity.

- Cheap knockoffs may not fit properly or may fail quickly, causing more problems than they solve.

2. **Misdiagnosis of Symptoms**

- Symptoms of a failing PCV valve (e.g., **oil leaks, rough idling, excessive crankcase pressure**) can also indicate other issues (e.g., **blown gaskets, valve train problems, or vacuum leaks**). Replacing the tube-breather alone may not resolve the underlying problem.

- A mechanic should **diagnose the issue properly** before replacement to avoid unnecessary expenses.

3. **Routine Replacement Required**

- While durable, the PCV valve is a **wear item** that should be replaced periodically as part of maintenance. Neglecting this can lead to **clogging, failure, or engine damage**.

- Some drivers may forget to replace it during regular servicing, leading to unexpected failures.

4. **Limited Lifespan in Harsh Conditions**

- In **extreme temperatures, high humidity, or environments with heavy engine strain**, the valve may wear out faster. Oil quality and engine maintenance also play a role in its longevity.

- Engines running on **low-quality oil or with poor ventilation** may experience premature failure.

5. **Installation Errors Possible**

- If not installed correctly (e.g., **not tightened properly, misaligned, or using the wrong gasket**), it can lead to **leaks or improper function**. This requires careful attention during replacement.

- Some DIYers may struggle with the installation if they lack experience with PCV systems.

6. **Not a Permanent Fix for Underlying Issues**

- If the **PCV hose is cracked, the crankcase is leaking, or the engine has internal damage**, replacing just the valve will not solve the problem. A full diagnostic is necessary.

- Other related components (e.g., **crankshaft seals, valve cover gasket**) may need attention simultaneously.

7. **Availability May Vary by Region**

- While widely available, some **less common Nissan models or older vehicles** may have difficulty finding this exact part, especially in remote areas.

- Online retailers (eBay, Amazon) may have stock issues, requiring patience or alternative sourcing.

8. **Potential for Over-Tightening**

- The valve is secured with a **small bolt**, and over-tightening can strip the threads or damage the valve housing. This requires careful handling during installation.

### **Conclusion**

The **Nissan 17338-6GP0A tube-breather** is a **practical and cost-effective maintenance item** for Nissan engines that rely on a functional PCV system. Its **OEM quality, ease of replacement, and role in preventing engine contamination** make it a worthwhile purchase for most drivers. However, **buyers must ensure they purchase a genuine part, diagnose the issue correctly, and replace it as part of regular maintenance** to avoid unnecessary problems.

- **Buy from a reputable seller** (Nissan dealership, trusted auto parts store, or verified online retailer).

- **Replace it at recommended intervals** (every **30,000 50,000 miles** or as part of routine servicing).

- **Have a mechanic confirm the issue** before replacement to rule out other potential problems.

- **Use high-quality oil and maintain proper engine ventilation** to extend the valve s lifespan.
