Why is my Nissan 370Z's engine making strange noises?

I recently purchased a used Nissan 370Z and have noticed that the engine makes strange noises when idling. It almost sounds like a rattling or clicking noise. What could be causing this and how can I fix it?

It's possible that the noise is coming from a loose or worn out fan belt. I would recommend taking your car to a mechanic to have them check the belt and make any necessary repairs.

Another possibility is that the noise is coming from a problem with the valves or lifters in the engine. This can be caused by build-up of sludge or debris. I would suggest having the oil changed and using a high-quality engine cleaner to address this issue.

Before you take your car to a mechanic, try checking the oil levels and topping off if needed. Low oil levels can also cause strange engine noises. It's always a good idea to regularly check your oil levels to keep your car running smoothly.
