Please tell me:
* What exactly is wrong with your engine? Is it making strange noises? Not starting? Running poorly?
* What year is your Prelude? The engine and parts will vary depending on the model year.
* Have you done any recent work on the engine? Sometimes a repair can lead to further problems.
* What's your budget? Fixing an engine can be expensive.
Once I have a better understanding of the situation, I can offer some potential solutions, like:
* Troubleshooting the issue yourself: If you're comfortable with basic car mechanics, you might be able to diagnose the problem and make some repairs.
* Taking it to a mechanic: A professional will be able to assess the damage and give you a quote for repairs.
* Replacing the engine: In some cases, a new or used engine might be the most cost-effective solution.
Remember: I'm just an AI, so I can't diagnose or fix your engine. But I can help you understand your options and guide you to the right resources.
