Knock this one up for not mocking up the whole motor first, I found out the 8mm head stud would not hold torque, the case saver pulled right out at 15 pounds grrrrrrrrrrrr. I was flying, the short block was done allready all that was needed to be done was put the cylinders on and install the heads and do rocker geometry. It was a walk in the park, my 10 year old was helping me assemble everything. She went to bed and I only had to torque the head studs down, and then it happened.
So the only fix I can think of since the case saver has an outer diameter of approx 12mm is to make up my own threaded insert larger than this and thread out the inside to 8mm. This happened on the lower #3 stud closest to the flywheel.
I wanted to be fabbing up the turbo system this weekend. we''ll see how this repair goes, hopefully I don't screw up the case with some goof up.
