Why is my Ford Mondeo engine making a strange noise?

I recently purchased a Ford Mondeo and I've noticed that the engine is making a strange noise. It's not a constant noise, but it happens periodically while I'm driving. I'm worried that it might be a serious issue. Can anyone offer any advice on what could be causing this and what steps I should take?

It's possible that the noise is coming from a loose belt or a faulty bearing in one of the engine components. I recommend taking your car to a trusted mechanic to have it checked.

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

Have you noticed any changes in your car's performance? Does it still accelerate and handle properly? If not, it could be a sign of a bigger issue.
