Strange engine noise in my Vauxhall Zafira Life

I have been noticing a strange noise coming from my engine in my Vauxhall Zafira Life. It sounds like a rattling or knocking sound. I'm not sure what could be causing it and I want to make sure it's not a serious issue. Any suggestions on what it could be?

It's possible that your engine could be low on oil and the noise could be coming from metal parts rubbing together. Check your oil level and if it's low, add more oil and see if that helps. If not, you may need to take your car to a mechanic for a more thorough inspection.

Another possibility could be loose or worn out belts. Check your serpentine belt and other belts for any signs of wear or looseness. If any belts need to be replaced, make sure to get them replaced as soon as possible to prevent any further damage.

Another potential cause could be a problem with your engine's timing chain or tensioner. This could result in the noise you are hearing. It's important to get this checked out by a mechanic as soon as possible to avoid any potential engine damage.
