Why is my Vauxhall Insignia engine making a knocking sound?

I recently noticed that my Vauxhall Insignia's engine is making a knocking sound, especially when I accelerate. It's never done this before, and I'm worried it could be a sign of a bigger issue. What could be causing this and how can I fix it?

Hi John, the knocking sound could be caused by several different things. It's important to get it checked out by a mechanic as soon as possible to prevent any further damage. It could be something as simple as a loose engine mount or a worn-out belt. However, it could also be a sign of a more serious problem, such as a faulty piston or rod bearing. In any case, it's best to have a professional take a look.

Hey John, I've had a similar issue with my Vauxhall Insignia before and it turned out to be a problem with the fuel injectors. The knocking sound could be due to dirty or clogged injectors, which can affect the smoothness of your engine and cause vibrations. I would recommend getting them cleaned or replaced by a mechanic.

Hi John, another possible culprit for the knocking sound could be low oil levels or dirty oil. It's important to regularly check and change your oil to keep your engine running smoothly. If the knocking continues, it's best to have a mechanic check for any internal engine damage.
