A real mechanic would never guess. U need to start with process of elimination. U want to narrow it down to the cylinder u hear the noise from try pulling the pwr on the coil and see if there is a change in sound if there is u found the cylinder. Then u need to ck compression. Hopefully its non of that and it's something simple.
I hope u had the air/fuel checked before u went out beating on it? If not this could be your own fault if its major.
