Why is the engine making a strange noise on my Ford Transit Custom?

I have a Ford Transit Custom and recently noticed an unusual noise coming from the engine. It's not super loud, but it's definitely noticeable. Is this something I should be concerned about?

It's always best to have any strange noises coming from your engine checked out by a mechanic. It could be a minor issue, but it's better to be safe than sorry.

I had a similar issue with my Ford Transit Custom and it turned out to be a loose belt. It was an easy fix, but it's always best to have a professional take a look.

It could be a simple fix, like changing the oil or air filter. But if the noise persists, it's probably best to take it to a mechanic.
