What is the cause of abnormal engine noise in a Vauxhall Movano?

I've noticed a strange clicking sound coming from my Vauxhall Movano's engine. It seems to be getting louder. What could be causing this and should I be concerned?

It's possible that there could be an issue with your engine's valves. They may need to be adjusted or replaced. It's best to have a mechanic take a look at it to determine the exact cause and recommend a course of action.

Another possible cause could be a failing water pump. This could also cause abnormal engine noise. Again, it's best to have a professional inspect your vehicle and make any necessary repairs.

If your Vauxhall Movano is an older model, it's possible that the timing chain may be worn and need to be replaced. This would also cause engine noise and should be addressed by a trained technician.
