I bought a Time-sert kit, taped down paper towels like Brian showed in that video, followed the instructions, and had metal shavings all over.
Just everywhere.
I dipped a couple dozen Q-tips in used oil and picked up all of the shavings that I could see. Then I poured used oil over the rocker arm assembly to wash out the shavings. I drained the oil and started tightening the valve cover bolts with a shiny new torque wrench.
Another is stripped and the threads that I inserted in the stripped hole attached themselves to the bolt.
Since I only make things worse, I guess that I will have it towed to the mechanic Monday morning and just sign over my credit card. If the new distributor does not fix my Accord, I will have him fix that one, too.
By the way, I keep posting each of these pictures on Imgur, and people keep downvoting the guy that is just trying to fix his own car.
Bonus?
