Ok long story short, broke the bolt off in the thermo housing on my GT 40 lower. I couldnt get it out so i drilled it out and tried to retap it. Well the aluminum didnt take the tap. So now i want to know what my options are. The only thing I can think of is to heli-coil it. Any other suggestions? I am trying to fix this without tearing apart the top half of the engine lol. If I pull it off there I will just buy a different intake lol.
