Why is my Ford Mondeo's engine making loud noises?

I recently purchased a used Ford Mondeo and I've noticed that the engine makes loud and unusual noises. It's concerning and I'm not sure what could be causing it. Has anyone else experienced this issue? What could be the possible causes and how can I fix it?

It's important to have your engine checked by a professional as soon as possible. It could be a sign of a serious issue.

Check the oil level and quality. Low oil or dirty oil can cause engine noises. If the oil is fine, it could be due to worn out engine components.

I had a similar issue with my Ford Mondeo and it turned out to be a faulty belt. Make sure to have all the belts checked.
