Why is my Ford Fiesta's engine making a strange clicking noise?

I recently noticed that my Ford Fiesta's engine is making a strange clicking noise. What could be the cause of this and should I be concerned?

The clicking noise could be a sign of a malfunctioning valve or lifter in your engine. It's best to have it checked by a mechanic as soon as possible to avoid further damage.

I've experienced the same issue with my Fiesta before. It turned out to be a loose or worn timing belt. I suggest having it replaced before it causes any serious damage to your engine.
