Review NOK Toyota Rear Crankshaft Seal fits TERCEL 1987–1999
The **NOK W0133-1638664 rear crankshaft seal** is a premium, high-performance replacement part meticulously engineered to restore sealing integrity and longevity to the rear main oil seal assembly of Toyota Tercel models produced between **1987 and 1999**. Crafted from **high-quality nitrile rubber (NBR)**, this seal is designed to withstand the demanding conditions of modern automotive engines, including exposure to extreme temperatures, high-pressure oil circulation, and the constant mechanical stress of crankshaft rotation. The seal features a **reinforced lip construction** with a precision-molded design, ensuring an optimal balance between flexibility and durability, which minimizes oil leakage while reducing the risk of premature wear or failure. Its **smooth, low-friction surface** is treated with a proprietary anti-wear compound, enhancing compatibility with the crankshaft s polished finish and extending the seal s operational life under heavy loads. Ideal for both professional mechanics and DIY enthusiasts, this seal is a direct-fit replacement, eliminating the need for modification or adaptation, and is backed by NOK s reputation for reliability and engineering excellence. Whether addressing a persistent oil leak, preparing for a major engine service, or upgrading an existing seal to prevent future issues, the **NOK W0133-1638664** delivers a robust, long-lasting solution that aligns with Toyota s original equipment standards.
Buying the **NOK W0133-1638664-NOK** (or a compatible alternative) for the rear crankshaft seal on a **Toyota Tercel (1987 1999)** involves weighing several factors. Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.
---
### **Pros of buying a NOK W0133-1638664-NOK Seal**
1. **OEM-Level Quality** NOK is a well-respected manufacturer known for producing high-quality seals that meet or exceed OEM specifications. Their products are designed to withstand the stresses of automotive applications, reducing the risk of premature failure.
2. **Compatibility** The part number suggests it is specifically engineered for the Toyota Tercel s rear crankshaft seal application, ensuring a proper fit and function. This reduces the likelihood of installation issues or leaks.
3. **Durability** NOK seals are often made from high-grade materials, such as nitrile rubber or other synthetic compounds, which provide better resistance to oil, heat, and mechanical stress compared to cheaper alternatives.
4. **Warranty and Support** NOK typically offers warranties or guarantees on their products, providing some assurance against defects. Their customer service and technical support can also be helpful if issues arise post-installation.
5. **Long-Term Reliability** A quality seal like this can extend the life of the rear main bearing assembly and reduce the risk of oil leaks, which can damage other components (e.g., the transmission or differential).
6. **Ease of Installation** Since it is a direct replacement, the installation process should be straightforward for someone with basic mechanical skills, assuming the surrounding components (e.g., housing, gasket) are in good condition.
7. **Prevents Costly Damage** A failing rear crankshaft seal can lead to oil leaks, which may contaminate the transmission or differential fluid, causing expensive repairs. Replacing it proactively can save money in the long run.

### **Cons of buying a NOK W0133-1638664-NOK Seal**
1. **Higher Upfront Cost** NOK seals are generally more expensive than generic or aftermarket alternatives. For budget-conscious buyers, this may be a significant drawback, especially if the seal is the only part needing replacement.
2. **Potential Overkill for Some Applications** If the seal failure is due to a minor issue (e.g., a loose bolt or minor wear), a premium seal may not be strictly necessary. In such cases, a more affordable option could suffice.
3. **Availability and Lead Times** Depending on the region or supplier, NOK parts may not always be in stock, leading to delays in ordering. Some aftermarket brands may have quicker availability.
4. **Installation Complexity** While the seal itself is straightforward, the process of removing the old seal and installing the new one may require disassembling parts of the engine or transmission. This could be time-consuming or challenging for inexperienced DIYers.
5. **Risk of Counterfeit Products** If purchasing from an untrusted seller (e.g., third-party online marketplaces), there is a risk of receiving a counterfeit or low-quality seal that fails prematurely. Always buy from reputable suppliers.
6. **Additional Costs** Beyond the seal itself, you may need to purchase tools (e.g., seal puller, torque wrench), gaskets, or cleaning solvents, adding to the total expense.
7. **Mixed Reviews on Fitment** While NOK is generally reliable, some users report slight variations in fitment or minor issues with certain applications. It s wise to check reviews or forums (e.g., Toyota Tercel owner groups) for specific feedback on this part number.

### **Conclusion**
The **NOK W0133-1638664-NOK rear crankshaft seal** is a strong choice for Toyota Tercel owners due to its high quality, durability, and compatibility. It is ideal if you prioritize long-term reliability, want to avoid potential oil leaks, and are willing to invest in a premium part. However, if budget is a concern or the seal failure is minor, a reputable aftermarket alternative (e.g., Gates, Febi Bilstein, or a Toyota-specific seal) may offer a cost-effective solution without sacrificing performance.
For most serious DIYers or those who want to ensure a long-lasting fix, the NOK seal is a **highly recommended option**. If you re unsure, verify the part number s fitment with your specific engine variant (e.g., 1.3L, 1.5L, or 1.6L) and consult a mechanic or Toyota Tercel forum for additional insights.

- You re purchasing from a trusted supplier to avoid counterfeits.
**Additional Tips:**- Always replace the old seal with a new one, even if it appears intact, to prevent future leaks.
