Why is my Nissan 370Z's engine making a ticking noise?

I have noticed that my Nissan 370Z's engine is making a ticking noise. It doesn't seem to affect the performance, but I'm still concerned. Any idea what could be causing this?

One possible cause of engine ticking noise could be low oil level. Check your oil levels and top up if necessary.

Another possibility could be a faulty lifter. This could require replacing the lifter or adjusting the valve clearance.

It could also be caused by a loose or worn timing chain. Have your mechanic check the timing chain tension and replace if necessary.
