So after I had removed all the head studs from the case, I noticed a couple had come out real hard, as if something was wrong with the threads. After cleaning the threads of the stud, I couldn't thread them back in the two suspect holes.
I got a 12mmx 1.5tap and chased those holes. Now, the head studs go right in and they wiggle!! Even after I bottom them out, they can be moved relative to where they exit the case. Is the case shot? What did I do wrong? |

While you were cleaning the studs, did you notice aluminum trapped in in the threads on the studs that came out hard?
If so, that might explain your loose fitting stud/hole combo... Inserts are the only way to fix that, and don't use a hand drill. They need to be installed with precision machinery to ensure the studs don't cock. By precison, the case has to be held flat on the machined surface and either a drill or a mill comes in perpendicular to the machined surface to ensure the inserts are oriented correctly. |
