Corroded stud

Thanks for the photos. I don't remember what you reported regarding the condition of the hole in the block, but it's not unusual for the threads in the block to survive at the depth where the threads on the stud are corroded away. I'm not sure about this, but it's entirely possible that the stud becomes the sacrificial anode and saves the threads in the block. Don
