Review NOK Rear Crankshaft Seal Infiniti Q50 fits 2014–2024

The **NOK 94KQH-MSP Rear Crankshaft Seal** is a premium, high-performance sealing solution meticulously engineered to ensure optimal protection and longevity for the rear crankshaft assembly in Infiniti Q50 models spanning the years 2014 through 2024, covering the **3.7L V6 (K37DE) and 5.0L V8 (VQ50DE)** engine variants. Crafted from NOK s proprietary **high-temperature-resistant elastomer compound**, this seal is designed to withstand extreme operating conditions, including high RPMs, intense heat buildup, and dynamic stress from the rotating crankshaft, all while maintaining a tight, leak-free interface. The **MSP (Metal Spring-Pak) construction** incorporates a robust, reinforced metal spring mechanism that provides consistent sealing pressure even as the seal compresses over time, mitigating the risk of oil leaks a common failure point in high-mileage or performance-driven engines. This design also enhances durability, reducing the likelihood of premature wear or deformation, which is particularly critical in applications where the crankshaft seal is subjected to frequent thermal cycling or aggressive driving conditions.

Beyond its structural integrity, the **NOK 94KQH-MSP** features a **precision-molded lip profile** optimized for the Infiniti Q50 s specific crankshaft diameter and housing geometry, ensuring a perfect fit that minimizes friction while maximizing sealing efficiency. The seal s **oil-resistant and abrasion-resistant formulation** protects against contamination from engine sludge, debris, or fuel dilution, which can accelerate seal degradation in real-world driving scenarios. Installation is further simplified by the seal s **pre-lubricated lip**, reducing the risk of dry-running damage during fitment a critical consideration when replacing seals in tight engine bays or under time constraints. Whether addressing a **leaking rear main seal**, preparing for a major engine overhaul, or upgrading for enhanced reliability in a modified engine, this NOK seal delivers a balance of **performance, longevity, and ease of installation** that aligns with the demands of modern high-performance applications. Built to meet or exceed OEM specifications, it serves as an ideal replacement for stock seals, offering peace of mind for both professional mechanics and discerning DIY enthusiasts seeking a dependable solution.

### **Pros and Cons of buying a NOK 94KQHMSP Rear Crankshaft Seal for a 2014 2024 Infiniti Q50 (V6 3.7L)**

#### **Pros:**

1. **OEM-Level Quality** NOK is a well-respected manufacturer known for producing high-quality seals that meet or exceed OEM specifications. This ensures a proper fit and reliable performance, reducing the risk of premature failure.

2. **Compatibility** The part number **94KQHMSP** is specifically designed for the **3.7L V6 engine (K37DE/K37DET)** found in the **2014 2024 Infiniti Q50**, ensuring an exact fit without modifications.

3. **Durability** NOK seals are engineered with high-quality materials, including reinforced rubber and corrosion-resistant coatings, which help extend the seal s lifespan under normal operating conditions.

4. **Ease of Installation** The seal is designed for straightforward replacement, though some mechanical skill is still required. Proper installation techniques (using a seal driver and torque specifications) are crucial to avoid damage.

5. **Warranty & Support** NOK offers warranties on their products, and many reputable auto parts retailers provide return policies if the seal fails prematurely due to manufacturing defects.

6. **Prevents Oil Leaks & Engine Damage** A failing rear main seal can lead to oil leaks, which contaminate the transmission fluid, damage the transmission, or cause engine sludge. Replacing it proactively avoids costly secondary repairs.

7. **Aftermarket Trust** NOK is a trusted brand in the aftermarket, meaning you ll find it stocked at most auto parts stores (AutoZone, RockAuto, Amazon, etc.), and there s a wealth of installation guides and reviews available.

---

#### **Cons:**

1. **Cost** At around **NOK 94KQHMSP**, the seal is priced higher than some generic aftermarket alternatives (though quality varies significantly). However, the investment is justified by longevity and reliability.

2. **Installation Complexity** Replacing the rear main seal requires **draining the transmission fluid, removing the transmission, and accessing the crankshaft**. This is a **multi-hour job** that may require professional help unless you have mechanical experience.

3. **Potential for Damage During Removal** If the seal is stuck due to age or corrosion, improper removal techniques (e.g., prying with a screwdriver) can **damage the crankshaft or seal bore**, requiring additional repairs.

4. **Additional Consumables Needed** Beyond the seal itself, you ll need:

- **Transmission fluid** (if draining and refilling)

- **Sealant** (optional, but recommended for a better seal)

- **Torque wrench** (critical for proper bolt tightening)

- **Special tools** (e.g., seal driver, crankshaft pulley removal tool)

5. **Risk of Contamination** If the old seal was leaking, oil may have seeped into the transmission or bellhousing. A **full transmission flush** may be necessary post-installation to prevent sludge buildup.

6. **Labor Costs if Professional Installation** If you don t perform the job yourself, labor costs (especially in high-demand areas) can add **several hundred to over a thousand NOK**, significantly increasing the total expense.

7. **Mixed Reviews on Longevity** While NOK is generally reliable, some owners report that **transmission-related issues (e.g., slipping, rough shifting) persist** even after seal replacement, suggesting underlying transmission problems may exist.

The **NOK 94KQHMSP rear crankshaft seal** is a **high-quality, reliable choice** for your **2014 2024 Infiniti Q50 V6**, offering **OEM-level performance and durability**. The **pros heavily outweigh the cons**, particularly if you prioritize **long-term reliability and preventing catastrophic engine/transmission damage**.

- **DIY if possible** watch detailed **step-by-step videos** (e.g., from **ChrisFix, EricTheCarGuy, or Haynes Manuals**) to minimize risks.
