How do I repair an aluminun engine block crack? A threaded mounting boss is cracked in half, with the half that cracked off missing. How do I reassemble the idler pulley mounting bolt to 1/2 of a female threaded hole?





RE: aluminum block cracked
Welding and retapping stripped threads in aluminum is often easier than using inserts. Only when you are welding large areas, such as broken cylinder heads (like in half, duh, been there, done that!)or when reconstructing complete combustion chambers,etc., will you need to do any normalizing or heat treating.
