Why is my Kia Ceed engine making a loud knocking noise?

My Kia Ceed was running smoothly until recently, when it started making a loud knocking noise from the engine. What could be causing this issue and how can I fix it?

The loud knocking noise from your engine could be due to a number of reasons. It could be a sign of low oil levels or a faulty bearing. It is best to take your car to a mechanic as soon as possible to diagnose and fix the issue before it causes further damage.

One possible cause of the loud knocking noise from your Kia Ceed's engine could be worn out spark plugs. As a general rule of thumb, spark plugs should be replaced every 30,000-50,000 miles. It is important to have them checked and replaced regularly to avoid any potential issues.

Another reason for the knocking noise could be a failing fuel injector. If the fuel injector is clogged or not functioning properly, it can cause the engine to make a knocking noise. A professional mechanic will be able to clean or replace the fuel injector for you.
