Why does my Ford Transit Custom make a loud knocking noise when I accelerate?

I recently bought a used Ford Transit Custom and noticed that it makes a loud knocking noise whenever I accelerate. It seems to be coming from the engine area. Is this something I should be concerned about?

It's possible that your engine may have a mechanical issue causing the knocking noise. It's best to get it checked by a mechanic as soon as possible.

Check the oil level and make sure it's not low. Low oil can cause knocking noises in the engine. If that's not the issue, it's best to take it to a mechanic for a proper diagnosis.
