Why is my Vauxhall Insignia's engine making a tapping noise?

My Vauxhall Insignia has recently started making a tapping noise when the engine is running. It seems to be coming from the top of the engine. What could be causing this and is it something I should be worried about?

It sounds like your engine could have an issue with the valves or lifters. This could be due to low oil pressure or a buildup of sludge in the engine. I recommend taking your car to a mechanic as soon as possible to get it checked out.

The tapping noise could also be caused by a loose or worn timing belt. If it's been a while since you've had your timing belt replaced, it may be time to get it checked and possibly replaced.

It's always best to err on the side of caution when it comes to strange noises coming from your engine. I would suggest scheduling a check-up with a reputable mechanic to diagnose the issue and prevent any further damage.
