Review NOK Mitsubishi Rear Crankshaft Seal fits LANCER 2002–2007

The **NOK W0133-1634364 rear crankshaft seal** is a premium, high-performance replacement part specifically engineered to restore optimal engine integrity and longevity for Mitsubishi Lancer models produced between 2002 and 2007. Crafted from NOK s proprietary **high-quality nitrile rubber compound**, this seal is designed to withstand the extreme pressures, temperatures, and mechanical stresses encountered in the rear main bearing housing of your vehicle s engine. The seal features a **precision-molded lip profile** that ensures a tight, leak-proof seal against the crankshaft, preventing oil leaks that can lead to costly engine damage, reduced performance, and premature wear. Its **reinforced steel backing plate** provides structural stability, preventing deformation under high torque loads, while the **optimized spring tension** guarantees consistent sealing performance over time, even as the engine operates under varying conditions. Ideal for both professional mechanics and DIY enthusiasts, this seal is a direct-fit replacement, eliminating the need for modification or adaptation, and is compatible with the 4G93 and 4G94 engines commonly found in these Lancer models. By installing this NOK seal, you not only address existing oil leaks but also enhance the durability of your engine s critical components, ensuring smoother operation, extended service life, and peace of mind on the road.

### Pros and Cons of buying a NOK W0133-1634364-NOK for a Mitsubishi Lancer (2002-2007) Rear Crankshaft Seal

#### **Pros:**

1. **Brand Reputation** NOK is a well-known and trusted brand in the automotive aftermarket, known for producing high-quality seals, gaskets, and bearings. Their products are often engineered to meet or exceed OEM specifications, ensuring durability and reliability.

2. **Compatibility** The part number (W0133-1634364-NOK) is specifically designed for the rear crankshaft seal on the 2002-2007 Mitsubishi Lancer, reducing the risk of fitment issues. This means it should align properly with the engine bay s geometry and mounting points.

3. **Longevity and Performance** NOK seals are typically made from high-quality materials, such as nitrile rubber or other synthetic compounds, which resist oil degradation, heat, and mechanical stress better than generic or low-quality alternatives. This can extend the life of the seal and reduce the likelihood of premature failure.

4. **Ease of Installation** Since it is an OEM-equivalent or upgraded part, it should be easier to install compared to aftermarket alternatives that may require additional modifications or tools. The design is optimized for the specific application.

5. **Warranty and Support** NOK often provides warranties on their products, offering some level of protection against defects. Additionally, they have customer support channels for assistance with installation or part issues.

6. **Prevents Oil Leaks and Contamination** A failing rear crankshaft seal can lead to oil leaks into the transmission or differential, causing costly damage. Replacing it with a reliable seal like the NOK part helps maintain proper lubrication and prevents contamination of other components.

7. **Potential Cost Savings in the Long Run** While the upfront cost may be higher than a generic seal, the durability and reduced risk of failure can save money by avoiding repeated replacements or damage to other systems (e.g., transmission).

---

#### **Cons:**

1. **Higher Upfront Cost** NOK parts are generally more expensive than generic or no-name alternatives. For budget-conscious buyers, this may be a significant drawback, especially if the seal is the only part needing replacement during a service.

2. **Potential Overkill for Minor Use** If the vehicle is not driven heavily or under extreme conditions (e.g., towing, extreme temperatures, or aggressive driving), a slightly less expensive seal might suffice without sacrificing performance. However, for most drivers, the extra cost is justified by reliability.

3. **Availability and Lead Times** While NOK parts are widely available, some specialty auto parts stores or online retailers may have limited stock. In rare cases, ordering may require waiting for shipment, which could delay repairs.

4. **Installation Complexity** Replacing a rear crankshaft seal often requires removing the transmission or differential, which can be labor-intensive. While the seal itself is straightforward, the surrounding components (e.g., flywheel, bellhousing, or transmission mounts) may need inspection or replacement. This could add to the total cost if professional labor is required.

5. **Risk of Counterfeit or Low-Quality Products** When purchasing online (especially from third-party sellers), there is a risk of receiving a counterfeit or inferior NOK part. Buying directly from authorized dealers, official distributors, or reputable retailers (e.g., RockAuto, Amazon, or local auto parts stores) minimizes this risk.

6. **Mixed Reviews on Specific Part Performance** While NOK is generally reliable, some users report that certain seals (depending on the model or year) may still fail prematurely due to design flaws, poor installation, or extreme operating conditions. Always check reviews or forums (e.g., Mitsubishi Lancer forums, Reddit, or YouTube) for user experiences with this specific part.

7. **Potential for Overengineering** For older vehicles with high mileage, some mechanics argue that replacing only the seal (rather than the entire transmission or differential) may not be worth the cost if those components are already worn. However, this is more of a decision about the overall service rather than the seal itself.

---

### **Conclusion:**

The NOK W0133-1634364-NOK rear crankshaft seal is a strong choice for the 2002-2007 Mitsubishi Lancer due to its reputation for quality, compatibility, and longevity. The higher cost is often justified by its reliability and the potential to avoid costly transmission or differential damage from oil leaks. However, the decision should also consider the vehicle s condition, driving habits, and budget.

If the vehicle is driven frequently or under demanding conditions, the NOK seal is the safest and most durable option. For occasional drivers or those on a tight budget, a high-quality generic seal (e.g., from brands like Fel-Pro or Gates) could be a cost-effective alternative, provided it meets the OEM specifications.

---

### **Recommendation:**

1. **Buy from a Trusted Source** Purchase the NOK part from an authorized dealer, official distributor, or a well-reviewed online retailer (e.g., RockAuto, Amazon, or local Mitsubishi dealerships) to avoid counterfeit products.

2. **Inspect Surrounding Components** If replacing the seal, take the opportunity to inspect the flywheel, transmission mounts, and differential for wear. Replace any damaged parts to prevent future issues.

3. **Follow Proper Installation Procedures** Improper installation (e.g., not torquing bolts correctly or using the wrong sealant) can void warranties and reduce seal life. Consult a Mitsubishi-specific repair guide or seek professional help if unsure.

4. **Consider Professional Installation** Given the complexity of accessing the rear crankshaft seal, hiring a mechanic with experience in Mitsubishi transmissions may be worth the cost to ensure a proper job.

5. **Monitor for Leaks Post-Installation** After installation, check for oil leaks around the seal during the first few weeks of driving. If leaks persist, contact the seller or mechanic for assistance.

**Final Verdict:** The NOK W0133-1634364-NOK is the **best choice** for most Mitsubishi Lancer owners due to its balance of quality, reliability, and compatibility. While it may cost more upfront, it offers peace of mind and long-term protection for the transmission and differential. For those on a tight budget, a high-quality generic seal can be a viable alternative if sourced carefully.
