What should I do since I already overtighting a bolt on the valve cover and the thread in the head is stripped? Do I need loctite on those bolts too? I was reading someone doing it not sure what loctite for. What should I do to restore the threat in the head? Not really feeling good about it..so please infom me. My torque wrench is destroyed and would not click and the first bolt I kept going and going looking for the click then the bolt keeps turning now with no force. Really angry since so many people use my wrench and someone destroyed it. Post reply please.. thanks!
