Why is my Toyota Corolla's engine making a strange noise?

I recently purchased a used Toyota Corolla and I've noticed that the engine is making a strange noise. It's not a loud noise, but it's definitely noticeable. I'm worried that there may be something wrong with the engine. Is this a common issue with Corollas? What should I do?

It's possible that there may be an issue with the timing belt or one of the engine components. I recommend taking your car to a mechanic for a diagnostic test.

I've had a similar experience with my Toyota Corolla. It turned out to be a loose belt. I tightened it and the noise went away. I would suggest checking your belts and see if that's the issue.
