What is causing the noise from my Vauxhall Movano's engine?

I have noticed a loud knocking sound coming from the engine of my Vauxhall Movano. It seems to be getting worse and I'm concerned about the potential damage it could cause. What could be causing this noise and how can I fix it?

It's possible that it could be a problem with the engine bearings. I recommend taking it to a trusted mechanic to have it checked out.

Another potential issue could be with the valves. Have a mechanic do a valve adjustment to see if that resolves the noise.

Make sure to check your oil levels regularly, as low oil could also be the cause of the noise. If it's low, top it off and see if the noise goes away.

If all else fails, it could be a more serious issue with the engine. Take it to a mechanic for a full diagnostic to determine the cause.
