Why is my Ford Mondeo's engine making a weird noise?

I recently bought a Ford Mondeo and I noticed that the engine is making a strange noise. It's not a constant noise but rather an intermittent one. What could be causing this and how can I fix it?

It's possible that there is an issue with your car's timing belt. I suggest taking it to a trusted mechanic to have it checked and potentially replaced.

Check your oil levels and make sure they are at the recommended level. Low oil can cause strange noises in the engine.

Have you noticed any other changes in your car's performance? It could be an indication of a larger issue. Take it to a Ford dealership for a diagnostic test.
