Review NOK Mitsubishi Rear Crankshaft Seal fits ECLIPSE 1990–1994

The **NOK W0133-1633892 rear crankshaft seal** is a precision-engineered, high-performance replacement part specifically designed to restore sealing integrity and prevent oil leaks in the rear main bearing housing of 1990 through 1994 Mitsubishi Eclipse models equipped with the 2.0L or 2.5L 4G93 or 4G94 inline-four engines. Crafted from NOK s proprietary **butyl rubber compound**, this seal is engineered to withstand the demanding conditions of high-pressure oil circulation, thermal fluctuations, and mechanical stress found in the engine s rear crankshaft area, ensuring a reliable barrier against oil leakage while maintaining optimal lubrication for the crankshaft and transmission input shaft. The seal features a **metal-reinforced lip design** with a precision-molded, self-adjusting lip profile that conforms seamlessly to the crankshaft s polished surface, minimizing friction and extending both the seal s lifespan and the engine s overall durability. Its **snap-ring groove compatibility** ensures a secure, interference-free fit within the engine block, preventing rotation or axial movement that could compromise sealing performance. Ideal for applications requiring a balance of durability and ease of installation, this seal is a direct-fit replacement for the original equipment manufacturer (OEM) component, eliminating the need for modification or customization. Whether addressing a persistent oil leak at the rear main seal, preparing for a transmission rebuild, or proactively maintaining engine longevity, the NOK W0133-1633892 delivers a robust, long-lasting solution that adheres to strict automotive industry standards for quality and performance.

### Pros and Cons of buying a NOK W0133-1633892-NOK Rear Crankshaft Seal for a 1990-1994 Mitsubishi Eclipse

#### **Pros:**

1. **Compatibility** The NOK W0133-1633892 is specifically designed for the 1990-1994 Mitsubishi Eclipse, ensuring a proper fit without modifications. This reduces the risk of installation errors that could lead to leaks or damage.

2. **Quality Material** NOK is a well-known manufacturer of high-quality seals, gaskets, and bearings. Their products are typically made from durable materials that resist wear, heat, and oil exposure, which is crucial for a crankshaft seal that must withstand engine stress.

3. **Reliability** A properly installed crankshaft seal from a reputable brand like NOK can last longer than generic or aftermarket alternatives, reducing the likelihood of frequent replacements. This is especially important in older vehicles where the transmission and engine components may already be worn.

4. **Ease of Installation** The seal is designed to fit standard tools and procedures, making it accessible for both professional mechanics and experienced DIYers. The packaging often includes installation instructions, which can simplify the process.

5. **Warranty and Support** NOK products often come with warranties or return policies, providing some assurance against defects. If the seal fails prematurely due to manufacturing issues, you may be able to get a replacement or refund.

6. **Prevents Contamination** A failing crankshaft seal can allow transmission fluid or oil to leak into the engine, causing contamination and damage to internal components. Replacing it with a high-quality seal like this helps maintain cleanliness within the transmission and engine.

7. **Cost-Effective for Long-Term Use** While the upfront cost may be higher than some generic alternatives, the longevity and reliability of a NOK seal can save money in the long run by avoiding repeated replacements or costly transmission or engine repairs.

---

#### **Cons:**

1. **Higher Upfront Cost** Compared to generic or no-name seals, the NOK W0133-1633892 is more expensive. This may be a deterrent for budget-conscious buyers, especially if they are unsure about the seal s necessity or the vehicle s overall condition.

2. **Potential Overkill for Minor Issues** If the seal failure is due to a minor issue (e.g., a small crack or wear from normal use), a slightly cheaper seal might suffice. However, in most cases, a high-quality seal is the best choice to prevent future problems.

3. **Installation Complexity** While the seal itself is straightforward, the process of removing the transmission or accessing the crankshaft seal can be labor-intensive, especially in older vehicles. This may require additional tools, patience, and possibly professional help, adding to the overall cost.

4. **Risk of Counterfeit Products** Purchasing from untrusted sellers (e.g., third-party online marketplaces) could result in receiving a counterfeit or low-quality seal. Always buy from authorized dealers, reputable online retailers, or directly from NOK to avoid this risk.

5. **Compatibility with Modified Vehicles** If the Mitsubishi Eclipse has been modified (e.g., performance upgrades, custom transmissions, or aftermarket parts), the stock seal may not fit perfectly. In such cases, a custom or upgraded seal might be necessary, which could increase costs.

6. **Time-Consuming Replacement** Replacing a crankshaft seal often requires draining the transmission fluid, removing the transmission, and possibly the flywheel or flexplate. This can take several hours, during which the vehicle is out of commission.

7. **Potential for Damage During Installation** If not installed carefully, there is a risk of damaging the seal, the crankshaft, or the transmission components. Improper installation can lead to leaks or premature failure, negating the benefits of a high-quality seal.

### **Conclusion:**

The NOK W0133-1633892 rear crankshaft seal is an excellent choice for a 1990-1994 Mitsubishi Eclipse due to its reliability, compatibility, and durability. While it comes at a higher cost than generic alternatives, the long-term benefits such as preventing transmission fluid leaks, reducing contamination, and minimizing the risk of costly repairs make it a worthwhile investment. However, the decision should also consider the vehicle s overall condition, your budget, and whether you are comfortable with the installation process.

If the seal is failing and you are experiencing leaks, oil contamination, or transmission issues, replacing it with the NOK seal is strongly recommended. For those on a tight budget or with minor seal wear, a high-quality generic seal (from a trusted brand) could be a compromise, but it carries a higher risk of failure.

---

### **Recommendation:** **Buy the NOK W0133-1633892 seal if:**

- You are experiencing crankshaft seal leaks or symptoms like transmission fluid dripping on the engine or a burning smell.

- You want a long-lasting, reliable seal that reduces the risk of future transmission or engine damage.

- You are confident in your ability to install it properly (or are willing to pay for professional installation).

- You are purchasing from an authorized dealer or a reputable seller to avoid counterfeit products.

**Consider alternatives if:**

- The vehicle is in poor condition and you are unsure whether the seal is the root cause of the problem (a transmission flush or inspection may be needed first).

- You are working with a very limited budget and can find a high-quality generic seal from a trusted brand (e.g., Gates or Fel-Pro) that fits the same application.

- The seal failure is minor and you are unsure whether the cost of replacement justifies the effort.

**Final Verdict:** For most owners of a 1990-1994 Mitsubishi Eclipse, the NOK seal is the best choice for a reliable and long-lasting fix. Prioritize quality over cost to avoid repeated issues and potential engine or transmission damage. If in doubt, consult a mechanic to confirm the seal s condition and whether other components (e.g., the transmission or flexplate) need attention during the replacement.
