Why is my Nissan Micra's engine making strange noises?

I have noticed that my car's engine has been making some unusual sounds lately. It seems to be coming from under the hood. What could be causing this and how can I fix it?

It could be a sign of an engine misfire or a worn-out valve. I recommend taking your car to a mechanic to have it checked out

Have you checked your oil level recently? Low oil can also cause strange engine noises. Make sure to top up your oil if needed.
