Why is my Ford EcoSport's engine making a rattling noise?

I've recently noticed that my Ford EcoSport's engine is making a rattling noise when I accelerate. It didn't use to make this noise before. What could be causing this and what should I do?

It's possible that your engine's timing chain is loose or worn out. It's best to take your car to a certified Ford mechanic to have it checked and replaced if necessary.

Another potential cause could be a failing accessory belt tensioner. This can also cause a rattling noise from the engine. Have it checked and replaced if needed to avoid any further damage.

Make sure to also check your oil levels and condition. If they are low or dirty, it could also contribute to the rattling noise. Consider getting an oil change and monitoring your oil levels regularly.
