Why does my Ford Mondeo engine make a rattling noise?

I've been noticing a strange rattling noise coming from my Ford Mondeo's engine. It only happens occasionally, but it's starting to worry me. I want to make sure it's not a sign of a bigger problem. Any ideas on what could be causing this?

The rattling noise could be a sign of loose or worn out parts in your engine. I would recommend taking your Ford Mondeo to a certified mechanic to have it checked out.

I had a similar issue with my Ford Mondeo, and it turned out to be a loose heat shield on the exhaust. Make sure to have all the heat shields checked and tightened.

Have you recently changed your oil? Sometimes using the wrong type of oil can cause rattling noises in your engine.
