Review NOK Engine Rear Crankshaft Main Oil Seal 9mm Japan Nos Part fits 110 1990

The **NOK BH0605E Engine Rear Crankshaft Oil Seal** is a high-performance, precision-engineered sealing solution specifically designed for compatibility with **Nissan (Infiniti) models** from the **2009 to 2011 model years**, particularly those equipped with **3.5L V6 engines** (such as the VQ35DE or VQ35HR variants). This oil seal is a critical component in maintaining engine integrity by preventing oil leakage from the rear main bearing housing while ensuring smooth operation of the crankshaft. Crafted from **high-quality nitrile rubber (NBR)**, the BH0605E features a **reinforced lip design** that delivers superior durability and resilience against heat, pressure, and mechanical stress, making it ideal for high-performance and daily-driving applications alike.

The seal s **precision-molded construction** ensures an optimal fit within the crankshaft housing, minimizing clearance and reducing the risk of oil contamination in the transmission or differential. Its **metal-reinforced outer diameter** enhances structural stability, allowing it to withstand the rigors of extended use without deformation or premature wear. Additionally, the seal incorporates a **smooth, low-friction lip profile**, which helps maintain consistent sealing performance while reducing the likelihood of crankshaft damage during installation or operation. This makes the NOK BH0605E an excellent choice for both **OEM replacement** and **aftermarket upgrades**, where reliability and longevity are paramount.

Whether installed during routine maintenance or as part of a **crankshaft seal replacement** due to leaks or wear, this seal is engineered to meet or exceed factory specifications, ensuring a **tight, long-lasting seal** that protects engine components from oil intrusion. NOK s reputation for **consistent quality and engineering excellence** is reflected in this product, making it a trusted choice for mechanics, tuners, and enthusiasts seeking a dependable solution for their **Nissan 3.5L V6 engines**. Proper installation with the correct tools and lubrication further extends its service life, ensuring optimal performance for thousands of miles.

### **Pros and Cons of buying a NOK BH0605E Engine Rear Crankshaft Oil Seal (Fits 90-110 Nissan Models)**

#### **Pros:**

1. **High Quality Material** NOK seals are known for their durable rubber compound and reinforced construction, which helps resist oil degradation and temperature fluctuations better than many generic alternatives.

2. **Precise Fitment** The BH0605E is specifically designed for Nissan engines in the 90-110 series (e.g., 2.0L QR20DE, SR20DE, etc.), reducing the risk of installation issues or leaks due to improper sizing.

3. **Longer Lifespan** Compared to cheaper aftermarket seals, NOK parts often last longer, especially in applications with moderate to high mileage, as they are engineered to handle stress better.

4. **Reliability** NOK is a well-established brand with a reputation for consistent performance, which can be reassuring when replacing critical engine components like crankshaft seals.

5. **Easier Installation** The seal comes pre-lubricated and is designed for straightforward installation, reducing the chance of damage during fitting compared to some other brands.

6. **Warranty Coverage** Many reputable sellers offer warranties on NOK seals, providing some protection against premature failure due to defects.

#### **Cons:**

1. **Higher Cost** NOK seals are more expensive than generic or no-name alternatives, which may be a concern for budget-conscious buyers.

2. **Potential Overkill for Low-Mileage Engines** If the seal failure is due to minor wear (e.g., in a well-maintained engine with low mileage), a slightly cheaper seal might suffice without sacrificing performance.

3. **Availability Issues** While widely available, some local auto parts stores may not stock NOK seals, requiring online purchases, which could add shipping time or cost.

4. **Installation Skill Dependency** Even with a well-made seal, improper installation (e.g., incorrect torque, misalignment, or improper sealing surface prep) can lead to leaks, negating the quality of the part.

5. **Compatibility Verification Needed** While the BH0605E fits many 90-110 Nissan engines, there are variations (e.g., QR20DE vs. SR20DE) where slight differences in crankshaft or housing dimensions might require additional attention during installation.

### **Conclusion:**

The **NOK BH0605E crankshaft oil seal** is a strong choice for Nissan owners in the 90-110 series due to its reliability, durability, and precise fitment. It is particularly justified if the engine has high mileage, experiences oil leaks frequently, or if you prioritize long-term performance over upfront cost. However, if the budget is tight and the engine is relatively new or well-maintained, a high-quality generic seal (e.g., from brands like Fel-Pro or Sealed Power) could be a cost-effective alternative without significant trade-offs.

For most cases, **the NOK seal is the recommended option** due to its balance of quality, longevity, and reduced risk of premature failure. Always verify the exact engine model and application to ensure compatibility, and ensure proper installation techniques are followed to maximize the seal s lifespan.

**Final Recommendation:** Purchase the **NOK BH0605E** if:

- You want a reliable, long-lasting seal.

- Your engine has significant mileage or a history of oil leaks.

- You are willing to pay a premium for a reputable brand.

Consider alternatives if:

- The engine is low-mileage and the failure is minor.

- You are on a tight budget and can find a similarly rated generic seal with good reviews.
