Why is my Vauxhall Movano's engine making a strange noise?

I recently noticed that my Vauxhall Movano's engine is making a strange noise whenever I accelerate. I've checked the oil and it seems fine, what could be causing this issue?

It's possible that there could be an issue with your engine's timing. I would recommend taking your van to a mechanic for a thorough inspection.

If the noise is more of a knocking sound, it could be a sign of worn out engine bearings. It's important to address this issue before it causes further damage.

Have you recently changed your air filter? It's possible that a dirty air filter could be causing the strange noise.

I would also suggest checking the condition of your spark plugs. If they are worn out or dirty, they could be causing the noise.
