Was changing the spark plugs in my 5.0 today, and noticed that the plugs were torqued in pretty tight. After pulling them all and replacing most of them, I began screwing in the one that is the second back from the front of the motor on the passenger side of the motor. It seemed like it was beginning to tighten......then complete looseness while turning :0 After some more turns it just suddenly stopped in the head and got tight. I started the car up, and it seems to run fine, but using the edge of the valve cover as a plane and looking down across it, I can see that the one spark plug is noticeably farther into the head than the others. If you feel around the base of the plug, the hexagonal portion that you crank on is a lot closer to the surface of the head than any of the other plugs on that side of the motor.
Am I just paranoid, or could something be up here? I plan on just running the thing and forgetting about it as the thing seems to run alright, but I really don't want to pull that plug out again. Anyone have anything like this happen?
