Can anyone identify this marble like sound coming from the engine?

 

No idea. If your mechanic has a mechanic's stethoscope they can use that to find where it's coming from.

Audio only doesn't give us much to work with.

 

not quite sure what you are trying to say, but it sounds like you have a bad engine wire harness, not a bad coil. Is this correct? The bad wire harness is causing the coil to make noise. If you fix the wire harness, the coil will stop making noise? Is this correct?

If so, find the bad wires, and solder them together. If you do it professionally, that should fix your wire harness problem.
