Why does my Ford Transit Custom's engine make a strange noise?

I have a Ford Transit Custom and recently I've noticed a strange noise coming from the engine. It only happens when I start the car and then goes away after a few minutes. What could be causing this and should I be worried?

It sounds like you may have a faulty belt or pulley in your engine. It's best to get it checked out by a mechanic to prevent any further damage.

This could be a sign of low oil levels or dirty engine oil. Check your oil and consider getting an oil change if needed.

It's possible that you have an exhaust leak which can cause strange noises. Have a mechanic inspect your exhaust system.
