It's important to get your engine checked by a certified mechanic as soon as possible to prevent any further damage. A potential cause for the knocking sound could be a worn out timing chain or tensioner. These should be replaced as soon as possible to avoid potential engine failure.

One possible cause of the knocking sound could be low engine oil. Make sure to check your oil levels and top up if necessary. If the issue persists, it's best to take your car to a mechanic for a full inspection.

In some cases, the knocking sound could be caused by faulty spark plugs or ignition timing. Make sure to have these checked and replaced if necessary. Proper maintenance of these components can improve your engine's performance and reduce the chances of the knocking sound reoccurring.
