What causes the Ford Fiesta's engine to make a loud clicking noise?

I've noticed that my Ford Fiesta's engine is making a loud clicking noise, especially when accelerating. What could be causing this and how do I fix it?

The clicking noise is most likely caused by a worn out engine belt. It's important to have this fixed immediately to avoid any further damage to your engine.

It could also be due to low oil levels or dirty oil. Make sure to check your oil levels regularly and get an oil change if needed.

Another possible cause is a faulty valve lifter. This can be fixed by replacing the lifter.
