Is the noise only exist when the engine is at idle?
Is it constant noise? Does it change frequency as the engine speed increases or decreases?
You could have various noises from an engine due to different reasons. It could be due to low oil. Or having improper fuel that is creating a knock.
If possible, upload a video so we can hear the noise.
Let me know if you have any questions.
