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

I recently noticed that my Nissan Navara's engine has been making some strange noises. Is this something to be concerned about? What could be causing it?

It could be due to a problem with the engine's valves or bearings. It's best to have it checked by a professional mechanic to properly diagnose and fix the issue.

Check the oil level and see if it needs to be changed. If that doesn't solve the issue, it could be a problem with the engine's timing chain. Have it checked by a mechanic for further inspection.

Is the noise coming from the exhaust? It could be a sign of a faulty exhaust system. Take your Nissan Navara to a trusted mechanic to have it inspected and potentially repaired.
