Thanks for all the advice guys... I was able to get these bolts out eventually, without the torch, but all these replies have got me thinking. my original question of whether to run the car for awhile to get the exhaust all hot was kind of along this same train of thought, and i was cautioned that if the engine wasn't cool, i risked damage to the aluminum threads as i tried to force the steel threads out. now i have heard many times before of the "hot wrench"... so now should i refine the answer to my original question to be: it will do you no good to run the car all day because it will not get hot enough--what you need is an oxy acetylene torch. this will not cause you to strip the aluminum threads and will not cause any warpage of any metal due to intense differential levels of heating across a small area. it will only help to get bolt out. now if only i had that torch.... |
