Crafted from Corteco s proprietary **high-quality synthetic rubber compound**, this seal is designed to withstand extreme temperatures, heavy loads, and constant mechanical stress, making it an ideal replacement for the factory-sealed unit.

The **pre-installed CFW (Corteco Fast Work) mounting ring** simplifies installation, allowing mechanics to fit the seal quickly and securely without the need for specialized tools or excessive adjustments, reducing labor time and potential damage to surrounding components. Built to meet or exceed OEM specifications, this seal is compatible with both **E-series and 4R100 transmissions**, making it a versatile choice for a wide range of Ford F-150 configurations. Whether you re performing routine maintenance or addressing a leak, the **Corteco W0133-1655665-CFW** delivers superior durability, sealing performance, and peace of mind, ensuring your vehicle operates smoothly and efficiently for years to come.

The **Corteco W0133-1655665-CFW** is a rear main seal (crankshaft seal) designed for Ford F-150 models from **1987 to 2010**. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the Corteco W0133-1655665-CFW Rear Crankshaft Seal**

1. **High-Quality Materials** Corteco is known for using durable, oil-resistant materials that help prevent leaks over time. The seal is designed to withstand the heat and pressure generated by the engine, reducing the risk of premature failure.

2. **Proper Fitment** This seal is specifically engineered for the Ford F-150 s rear main housing, ensuring a tight seal and minimizing oil leaks. It is designed to match the engine s dimensions, reducing the chance of installation errors.

3. **Easy Installation** Corteco seals are generally straightforward to install, especially if the old seal was removed properly. The design often includes features like a smooth lip or reinforced edges to help with seating.

4. **Compatibility with Aftermarket Upgrades** Since this seal fits a wide range of Ford F-150 engines (including those with performance modifications), it can be a reliable choice even if you ve made engine upgrades.

5. **Warranty and Reliability** Corteco products typically come with a warranty, and the brand has a reputation for reliability in the automotive aftermarket. Many users report long-term performance without leaks.

6. **Cost-Effective Alternative to OEM** While not an original Ford part, this Corteco seal is often priced competitively compared to OEM replacements, offering good value for the performance.

7. **Resistant to Oil Degradation** The materials used in Corteco seals are formulated to resist oil breakdown, which helps maintain sealing integrity over time, especially in high-mileage or heavily used engines.

### **Cons of the Corteco W0133-1655665-CFW Rear Crankshaft Seal**

1. **Potential for Leaks if Installed Improperly** Like any seal, if not installed correctly (e.g., improper seating, debris in the housing, or incorrect torque on the housing bolts), it may leak. This requires careful attention during installation.

2. **Not an Original Equipment (OEM) Part** While Corteco is a reputable brand, some purists or mechanics prefer OEM parts for peace of mind, especially if the engine is heavily modified or has unique requirements.

3. **Limited Availability in Some Regions** Depending on where you purchase it, this specific seal may not be as widely stocked as more common OEM or generic alternatives, requiring online ordering or specialty auto parts stores.

4. **Mixed Reviews on Durability in Extreme Conditions** In rare cases, users with very high-performance engines or those running extreme oil temperatures may report shorter seal life. However, this is not universal and depends on engine conditions.

5. **Requires Proper Cleaning Before Installation** The rear main housing must be thoroughly cleaned of old gasket material, oil, and debris to ensure the new seal seats correctly. Neglecting this step can lead to leaks.

6. **Potential for Over-Tightening During Installation** If the housing bolts are overtightened, it can damage the seal or warp the housing, leading to leaks. Proper torque specifications must be followed.

7. **Not All Ford F-150 Engines Are Identical** While this seal fits most 1987 2010 F-150 models, some variations (e.g., different crankshaft diameters or housing designs) may require additional attention or a slightly different seal.

### **Conclusion**

The **Corteco W0133-1655665-CFW** is a **solid, high-quality aftermarket replacement** for the rear crankshaft seal in Ford F-150 models from 1987 to 2010. It offers **reliable sealing performance, ease of installation, and cost-effectiveness** compared to OEM options. The brand s reputation for durability and oil resistance makes it a **trustworthy choice** for most applications, provided it is installed correctly.

However, it is **not without drawbacks** improper installation, lack of OEM status, and potential regional availability issues could be concerns for some buyers. If you prioritize **long-term reliability and ease of use**, this seal is an excellent pick. If you prefer **OEM parts or have a highly modified engine**, you may want to compare it with an original Ford seal or consult a mechanic for the best fit.

### **Recommendation**

- You need a **reliable, cost-effective aftermarket seal** for your Ford F-150 (1987 2010).

- You are **comfortable with proper installation techniques** (cleaning the housing, correct torque, etc.).

- You want a **well-regarded brand** with a history of good performance in similar applications.

- You **prefer OEM parts** for maximum compatibility, especially with modified engines.

- You **cannot find the seal locally** and are unsure about ordering online.

- You have **extreme engine conditions** (e.g., forced induction, extreme heat) and want to verify if a higher-end seal (like a performance-specific one) is necessary.

**Final Verdict:** For most standard to moderately modified Ford F-150 owners, the **Corteco W0133-1655665-CFW is a strong, practical choice** that balances quality and affordability. Always follow installation guidelines carefully to maximize its lifespan.
