What are the common problems with the Vauxhall Insignia engine?

I have noticed some issues with my Vauxhall Insignia's engine lately. I am not sure what might be causing them. Can you give me an insight into the common problems that occur with this car model's engine?

One common issue with Vauxhall Insignia engines is oil leaks. It is important to check for any signs of oil leaks and get them fixed as soon as possible to prevent further damage.

Another potential issue could be with the timing belt. It is recommended to get the timing belt checked regularly and replace it if necessary to avoid any engine problems.

Clogged fuel injectors can also cause problems with the engine's performance. It is advised to use high-quality fuel and get the injectors cleaned regularly to avoid any issues.
