Quick update on the on going fight.
I ran a tap down the stud hole, cleaned the stud with a die, put JB weld into the hole and put the stud in. Let it sit for a few days then re attempted to torque the stud. Sale result, the stud would not hold 11 lbs of torque.
What I am doing now: I have a insert that fits securely to the stud, I will be putting this insert into the stud hole, and putting this SOB down for good
I have been having the hardest time finding the proper thread and size for this stud and stud hole. Any idea on why? the stud doesn't seem too worn is it just a difference in Japanese threads?
The head studs are usually 8 mm x 1.25 pitch on both ends of the head studs. If it has the flanged head studs the part that goes into the cylinder is 10 mm x 1.25 pitch
