Seeing pics in this thread reminds me why I got out of being a tech, having to deal with stupid people. Wish I had some old pics of the stuff I've worked on. The time when I first started and a car had a spark plug for a drain plug and when a F150 came in on a hook with a hole through the hood. The customer tried changing his spark plugs himself, stripped the threads in the head and JB welded it on to hold it in place. Went to start it and plug shot through his hood.
