This is not Tacoma related, but I was just curious. A customer of mine came in this morning with her 2001 Hyundai. She was complaining of an intermittent "tick" noise from her engine. Sure enough we could hear it. It was somewhat consistent about every 8 seconds I would guess. Inspection showed something I had never seen or heard of before. Every 8 seconds a spark would arc from the harmonic balancer to the timing cover (an air gap of about 1/4 inch)
I had never seen this before, but when I did some searching I found that it is actually pretty common, and a result of static electricity buildup. I would think under the hood, where there is a chance of oil or fuel leaks, that this would be a bit of a concern, but I have not found any evidence of a fire linked to this. Has anyone else out there seen this before?
