Tom, ohming the wires will not show if it is arcing through the insulation. Just look and inspect the wire around the suspected area. While idling, mist some water in there. You'll now right away if it is indeed arcing. I wonder if the sharpness of the valvecover cut in? If it is arcing, there will be gray streaks, and the silicone might be crispy. Let me know either way. Thanks. Good luck on start up.
