Why is my Nissan Micra engine making weird noises?

I recently bought a secondhand Nissan Micra and noticed that the engine makes a strange noise when I start the car. What could be causing this issue and how can I fix it?

It is possible that there is an issue with your engine's components, such as the valves or pistons. I recommend taking your car to a trusted mechanic for a diagnostic check. They will be able to identify the cause of the noise and provide you with a solution.

If your Nissan Micra has a timing chain rather than a timing belt, it could be worn or loose, causing the noise. I suggest taking your car to a reputable dealership for inspection and potential replacement.

Have you recently changed your oil? If not, it could be low or dirty, causing the engine to make strange noises. I advise checking your oil level and replacing it if necessary.
