Factors to Consider:
* Severity of the Crack: A small crack might be repairable with welding or epoxy, but larger cracks or those in crucial areas (like the cylinder walls) are often difficult to fix effectively.
* Engine Type: The type of engine in your Protege (1.6L or 2.0L) might influence repair options.
* Cost vs. Value: Repairing a cracked block can be expensive, especially if it requires specialized welding or machining.
* Overall Condition of the Engine: Is the engine generally in good condition, or are there other significant problems?
Repair Options:
* Welding: Some cracks can be repaired with specialized welding techniques. However, this can be complex and requires a skilled welder familiar with engine blocks.
* Epoxy: Epoxy can be used to seal small cracks, but it's not always a permanent solution.
* Sleeving: In severe cases, the cracked cylinder can be replaced with a sleeve, but this is a very expensive and time-consuming process.
Alternatives to Repair:
* Engine Replacement: Replacing the engine entirely might be a more cost-effective solution, especially if the engine has significant mileage or other issues.
* Used Engine: A used engine from a salvage yard could be a less expensive option than a new one.
Recommendation:
It's best to take your Protege to a reputable mechanic for a thorough inspection. They can assess the severity of the crack and recommend the most appropriate repair option based on your specific situation. They can also advise you on the cost and potential risks involved.
Remember: Before making any decisions, consider the cost of repairs versus the overall value of your car. It might not be financially feasible to repair a cracked block if the vehicle is getting older or has other maintenance needs.
