hey everybody, I havent been on here for a month or so, been busy with school. Anyway, to the question. I have a 95 six lug chevy k2500 me and my dad have had for a couple months and ive been doing odds and ends to it recently to help get it in a little better shape. When we first got it, the drivers side exhaust manifold gasket was completely busted and she was ticking like crazy. Anyway we replaced the gasket a while ago and the ticking almost stopped, but there was still a little bit coming from the passenger side manifold. So i was feeling ambitious last sunday and decided i would replace it. Long story short, someone had already rung the head off the back bolt and the next one towards the front had a bolt in it when i took the manifold off but im pretty sure the threads are stripped inside the head because when i attempt to thread the bolt back in it just turns inside of the head. If i take the inner fender and tire off, i can get a drill perpendicular to the head, so Im planning on drilling out the stripped hole and putting in a helicoil. For the bolt that is rung off inside the head, I am planning on trying to drill it out with a left handed drill bit because ive heard that ez outs usually do more harm than good. My question is will the stuck bolt have more chance of coming out on the drill bit if the engine is relatively hot than if it is cold. I realize I will have to let it cool for a while before i will be able to remove the manifold without burning myself.
