Review FEL PRO Subaru Tcs 45957 Crankshaft Seal Kit fits IMPREZA 1993–1998

The **Fel-Pro TCS 45957 Crankshaft Seal Kit** is a premium, high-performance replacement solution meticulously engineered to restore sealing integrity and prevent oil leaks in the 1993 1998 Subaru Impreza with the EJ20 or EJ22 engine family. Designed with Fel-Pro s proprietary **Thermal Compound Sealant (TCS) technology**, this kit delivers an unmatched combination of durability, reliability, and ease of installation, ensuring a long-lasting, leak-free seal that outperforms conventional rubber or silicone alternatives.

The seal s precision-engineered lip design minimizes friction while maintaining a tight, consistent seal against the crankshaft s polished surface, reducing the risk of premature wear or failure. Complementing the seal is Fel-Pro s **pre-applied thermal compound**, a high-performance adhesive that bonds securely to both the engine block and the seal itself, eliminating the need for additional sealants and ensuring a perfect, gap-free fit from the moment installation begins. This eliminates the guesswork often associated with traditional seal kits, where improper application can lead to leaks or improper seating. Built to meet or exceed OEM specifications, the TCS 45957 kit is compatible with all 1993 1998 Subaru Impreza models equipped with the EJ-series engines, including the 2.0L and 2.2L variants, providing a universal solution for both naturally aspirated and turbocharged applications. Whether addressing a persistent oil leak at the rear main seal or performing a routine maintenance overhaul, this kit offers a hassle-free, professional-grade replacement that restores engine integrity and extends the life of your vehicle s critical components. With Fel-Pro s reputation for quality and performance, this crankshaft seal kit is the trusted choice for mechanics and DIY enthusiasts alike, ensuring a reliable, long-term solution for maintaining your Subaru s powerplant.

The **Fel-Pro TCS-45957 Crankshaft Seal Kit** is a popular choice for replacing the rear main seal (crankshaft seal) on 1993 1998 Subaru Impreza models, particularly those with the EJ20 or EJ22 engine. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Fel-Pro TCS-45957 Crankshaft Seal Kit**

1. **High-Quality Materials**

Fel-Pro is a well-respected brand in the aftermarket automotive parts industry, known for using durable materials like nitrile rubber and reinforced backing plates. This ensures better longevity and resistance to oil and heat compared to cheaper alternatives.

2. **Proper Fitment**

The kit is specifically designed for the 1993 1998 Subaru Impreza (EJ20/EJ22 engines), meaning it should align correctly with the engine s crankshaft and housing. This reduces the risk of leaks due to improper sizing.

3. **Ease of Installation**

Fel-Pro kits often come with clear instructions and sometimes include tools or gaskets to simplify the replacement process. The seal is pre-lubricated in some cases, making installation smoother.

4. **Widely Available and Trusted**

Fel-Pro is a widely distributed brand, so finding the part is rarely an issue. Dealerships, auto parts stores, and online retailers (e.g., RockAuto, Amazon, local shops) stock it. Additionally, mechanics and DIYers frequently recommend it due to its reliability.

5. **Good Warranty Coverage**

Fel-Pro typically offers a limited warranty (often 12 24 months), which provides some peace of mind in case of premature failure. This is more than many generic or no-name brands offer.

6. **Compatibility with Aftermarket Upgrades**

If you ve modified your engine (e.g., turbocharging, forced induction), Fel-Pro s seals are often recommended because they can handle higher pressures and temperatures better than stock seals.

7. **Positive User Feedback**

Many owners and mechanics report successful installations with minimal leaks after using this kit. Reviews often highlight its durability, especially in high-mileage or modified engines.

### **Cons of the Fel-Pro TCS-45957 Crankshaft Seal Kit**

1. **Cost**

The kit is more expensive than generic or no-name alternatives. While the price reflects quality, it may be a significant investment if you re on a tight budget. Prices typically range from **$50 $100**, depending on the retailer.

2. **Requires Professional or Skilled DIY Installation**

Replacing a crankshaft seal is a labor-intensive job that demands precision. Improper installation such as not cleaning the mating surfaces, overtightening bolts, or misaligning the seal can lead to leaks or even damage to the crankshaft. If you re not experienced with engine work, hiring a mechanic may be necessary, adding to the cost.

3. **Potential for Leaks if Not Installed Correctly**

- Not using the correct amount of sealant (if required).

- Not compressing the seal evenly.

- Damaging the seal during installation.

Proper preparation (cleaning the crankshaft and housing) is critical.

4. **Limited Availability of Specific Tools**

Some steps in the installation (e.g., removing the transmission or flywheel) may require specialized tools like a transmission jack or a crankshaft pulley removal tool. If you don t own these, you ll need to rent or purchase them.

5. **Time-Consuming Process**

The job can take **4 8 hours** for a skilled DIYer, depending on your tools and experience. For a mechanic, it might take **2 4 hours**, but labor costs can add up quickly.

6. **Risk of Damage to Other Components**

During installation, there s a chance of accidentally damaging the flywheel, flexplate, or transmission components if you re not careful. This could lead to additional repair costs.

7. **Not a Permanent Fix for Underlying Issues**

- A worn crankshaft journal.

- A damaged seal housing.

- Improper torque specifications during installation.

In such cases, the seal itself may not be the root cause, and further diagnostics are needed.

### **Conclusion**

The **Fel-Pro TCS-45957 crankshaft seal kit** is one of the best aftermarket options for 1993 1998 Subaru Impreza engines due to its reliability, proper fitment, and high-quality materials. It strikes a balance between cost and performance, making it a favored choice among mechanics and enthusiasts. However, its value is only realized if installed correctly either by a professional or a meticulous DIYer.

The kit s drawbacks primarily its cost and the complexity of installation are outweighed by its durability and reduced risk of leaks compared to cheaper alternatives. If you re dealing with a persistent oil leak or preparing for a major engine project, this is a strong recommendation.

---

### **Recommendation**

- **If you re comfortable with advanced engine work and have the time**, purchase the **Fel-Pro TCS-45957 kit** and follow a detailed step-by-step guide (such as those from **Subaru-specific forums** or **YouTube tutorials**). Invest in proper tools (e.g., torque wrench, sealant if required) to ensure a clean installation.

- **If you lack experience or tools**, hire a **trusted mechanic** to perform the replacement. Look for someone with Subaru experience, as improper installation can void warranties or cause further damage.

- **Consider complementary products**: Alongside the seal, replace the **transmission oil seal** (if applicable) and ensure the **crankshaft is clean and undamaged**. Using a **high-quality gasket maker** (like Permatex 24000) can also help prevent leaks.

- **Budget alternative**: If cost is a major concern, compare with other reputable brands like **Valeo** or **Duralast**, but be aware that they may not offer the same level of durability or warranty coverage.

**Final Verdict**: The Fel-Pro TCS-45957 is the **best overall choice** for this application, provided the installation is done correctly. It s worth the investment for long-term reliability, especially in high-mileage or modified engines.
