The **Apex ATC2040** is a popular aftermarket crankshaft seal kit designed for 1990-1992 Mitsubishi Eclipse engines. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Apex ATC2040 Crankshaft Seal Kit**

1. **High-Quality Materials** Apex is known for using durable, oil-resistant materials that improve longevity compared to OEM seals. The kit often includes a reinforced rubber or synthetic seal with a metal or reinforced backing for better stability.

2. **Improved Reliability** Many owners report fewer leaks and longer service life compared to stock seals, which can degrade quickly due to heat and oil pressure. The Apex seal is designed to resist warping and cracking over time.

3. **Easy Installation** The kit typically comes with clear instructions and often includes tools like a seal installer or removal tool. The design is straightforward, making it accessible for DIY mechanics, though some may still prefer professional installation.

4. **Compatibility** The Apex ATC2040 is specifically engineered for the 1990-1992 Mitsubishi Eclipse s 2.0L and 2.5L engines (4G63 and 4G93), ensuring a proper fit without modifications.

5. **Positive User Feedback** Many reviews highlight that this seal kit resolves persistent oil leaks at the crankshaft front seal, a common issue in these engines. Users appreciate the cost-effectiveness compared to engine rebuilds or replacements.

6. **Warranty Coverage** Apex often provides a warranty (typically 12-24 months), offering peace of mind in case of premature failure.

7. **Cost-Effective Solution** Replacing just the seal is far cheaper than addressing a blown seal that leads to oil leaks, engine damage, or a need for a timing belt replacement (if applicable).

### **Cons of the Apex ATC2040 Crankshaft Seal Kit**

1. **Not a Permanent Fix for Underlying Issues** If the engine has other problems (e.g., worn bearings, oil leaks from other sources, or excessive crankshaft runout), replacing just the seal may not solve the root cause. A thorough inspection is recommended before installation.

2. **Requires Some Mechanical Skill** While the installation is manageable for experienced DIYers, it can be tricky for beginners. Misalignment or improper sealing can lead to leaks. Some users report difficulty removing the old seal or aligning the new one correctly.

3. **Potential for Improper Installation** If not installed properly, the new seal may leak or fail prematurely. This is why many mechanics recommend professional installation, especially if the engine has been previously modified or abused.

4. **Limited Availability of Parts** While Apex is widely available, some specialty auto parts stores may not carry it, requiring online ordering. Shipping times can add to the inconvenience.

5. **Cost Relative to Engine Work** While cheaper than a full engine rebuild, the labor cost for installation (if not DIY) can be significant, especially if additional work (e.g., timing belt replacement) is needed.

6. **Durability Varies by Engine Condition** In high-mileage or heavily modified engines, the seal may not last as long as in a well-maintained stock engine. Oil quality and engine cleanliness also play a role in longevity.

### **Conclusion**

The **Apex ATC2040 crankshaft seal kit** is a solid choice for addressing oil leaks at the front crankshaft seal in 1990-1992 Mitsubishi Eclipse engines. It offers superior durability and reliability compared to OEM seals, making it a cost-effective solution for many owners. However, its effectiveness depends on proper installation and the overall health of the engine. If the engine has other issues (e.g., worn bearings, excessive crankshaft runout, or oil leaks elsewhere), replacing just the seal may not be sufficient.

For most DIYers with moderate mechanical skill, this kit is a practical and affordable option. However, those uncomfortable with engine work or dealing with a high-mileage engine might benefit from professional installation or a more comprehensive inspection.

### **Recommendation**

- You re experiencing oil leaks at the front crankshaft seal.

- Your engine is in decent condition with no other major issues.

- You re comfortable with a DIY installation or can afford professional labor.

- You want a higher-quality seal than the OEM part.

- Your engine has high mileage or signs of wear (check for bearing play, oil leaks elsewhere, or excessive crankshaft runout).

- You re unsure about your mechanical ability professional installation is strongly recommended in such cases.

- You plan to replace the timing belt or water pump at the same time (many mechanics recommend this as a preventive measure).

- **Torrington or Gates crankshaft seals** These are also high-quality brands with strong reputations.

- **Full Engine Inspection** If leaks persist or the engine shows other signs of wear, a mechanic may recommend a more thorough check before just replacing the seal.

Ultimately, the Apex ATC2040 is a well-regarded kit for this application, but its success hinges on proper installation and engine condition. If in doubt, consult a trusted mechanic to assess whether this is the best solution for your specific situation.
