Why is the Ford Transit Custom engine making strange noises?

I recently purchased a Ford Transit Custom and I've noticed that the engine is making some unusual noises. It sounds like a knocking or rattling sound. I'm not sure what could be causing this. Any advice on what I should do?

It's possible that there could be an issue with the engine or one of its components. I recommend taking your Ford Transit Custom to a trusted mechanic to have it checked out.

I had a similar issue with my Ford Transit Custom and it turned out to be a loose belt. Make sure to have all belts and pulleys checked during regular maintenance.

Check your oil levels and filter. Low oil levels or a clogged filter can cause strange engine noises. If that doesn't solve the issue, it's best to have a professional inspect it.
