Why does my Nissan Micra's engine make a ticking noise?

I recently purchased a used Nissan Micra and noticed that the engine has a noticeable ticking noise. Is this normal or should I be concerned?

It is not uncommon for older Nissan Micras to develop a ticking noise in the engine. This could be due to worn out lifters or a loose timing belt. It is important to have a mechanic inspect the engine to determine the root cause of the noise.
