You NEVER have to pull the heads to repair the plug chamber threads. They're repaired (Time sert) in place and it's a quick procedure anyone can do at home. If you can follow direction, you'll never have to do it again.

Jbrew I dont believe its a matter of over tightning and stripping i believe its a lack of maintanence. The threds of the plug is iron alloy and the head is alluminum They expand and contract at different rates allowing the plugs to work there way lose. then the last threads can not hold the preasure and blow striping part of the threads. Then they bounce up and down until they damage the rest of the threads. Lets face it no one shuts down there engine the minute theres a strange noise and the plugs are not easy to reach so we have a tendency to not check them every ounce in a while.

Your correct with some of your thoughts, -sort of. Not exactly, but close lol. Add in engine vibration to assist with plug loosening. Nobody should EVER have to check plug torque between changes.
You can Time sert #4 in vehicle. Yes , it's harder than the rest. You have to remove the harness cradle and maybe a HC line on some models. Then w/bungies, tie everything back tight and out of the way. Personally, I'd pull the motor before resorting to removing the heads. IMO, an in vehicle head job is a PITA.
