Why is my Nissan Micra engine making a weird noise?

I recently bought a used Nissan Micra and I noticed that the engine makes a weird noise. Should I be concerned and what could be causing this? Any tips on how to address this issue?

It's important to take action when you notice strange noises coming from your engine. It could be a sign of a bigger problem, such as low oil levels or a faulty engine component. I would recommend taking your car to a trusted mechanic for a thorough inspection.
