Also, if paint is removed around the coil clamp bolt holes, and then begins to rust or corrode, that ground is compromised. It would show up after some vibration. Just tightening the clamp hardware won't fix it, the area needs to be cleaned, the clamp needs to be cleaned, and remounted.

Sorry to dispute, but a coil needs no ground, the primary circuit goes in and out of the coil and the secondary circuit goes to ground after jumping the plug gap. It will operate fine hanging in mid air.
