Why just this one plug? All one cylinder head? Was thinking maybe ill run a ground wire directly from the cylinder head? Think there are tapped 7/16-14 holes i could bolt a cable to.
For the life of me i just dont understand how the header could be more grounded than the engine. The engine ground looks and feels good, but maybe the next step is to remove it and clean it good…

Do you actually SEE this spark jumping?
How about a video? That would help other eyes for diagnosis.
A suspect bad rod bearing AND a sparking issue DOES NOT HAPPEN AT THE SAME TIME.
