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

I recently started noticing a rattling noise coming from the engine of my Ford Puma. It only seems to happen when the car is idling and it's getting louder and more frequent. What could be causing this and how can I fix it?

The most common cause of a rattling noise coming from the engine is a loose or damaged part. It's important to have this checked by a mechanic as soon as possible as it could lead to further damage if left untreated.

Another possibility is that the rattling noise is being caused by low oil levels or dirty oil. Make sure to check your oil levels and if they are low, top it up. If the oil is dirty, have it changed as soon as possible.

If neither of those solutions solve the issue, it could be a problem with the timing chain or belt. This will require a mechanic's expertise to fix, so don't hesitate to take your car in for a proper diagnosis.
