Missing parts are always frustrating and there’s nothing more annoying than missing threads. Yes, you try to tighten the bolt into the engine block, but there are no threadsthere – and no way to put a nut on the other side.
Well, back when I was a boy and my dad had this problem with some old tractor, he would just drill the hole out, rethread the hole to the next size larger bolt and move on.
