2006 Kia Rio Question: electrical arcing from timing cover to crankshaft pulley when running.Any ideas?

occurs whenever vehicle is started and running at idle. as crank is turning, there is an intermittant arc that goes from timing cover to the crankshaft after the vehicle is at operating temp. I hve never seen this before. -
Answer 1
Bolt holding the plastic timing cover on is hitting/rubbing the crank pulley! Creating sparks. That's my guess. -
Answer 2
