Why is the engine of my Vauxhall Astra making strange noises?

Recently, my Vauxhall Astra has been making strange noises from the engine. What could be the cause of this and how can I fix it?

The strange noises coming from your engine could potentially be due to a faulty exhaust manifold gasket or a leak in the exhaust system. I recommend taking your car to a trusted mechanic for a thorough inspection and repair, if needed.

Another possible cause of the strange noises could be a worn out serpentine belt. I suggest having your car's serpentine belt checked and replaced if necessary.

It's also possible that the noise is coming from a problem with the engine's timing belt. This is a crucial component in the engine, so it's important to have it checked and replaced regularly to avoid potential damage.
