The reason bolts broke was BECAUSE internal water pipe leaked. In the presence of moisture, steel and aluminum weld themselves together. A real catch-22, eh? If the pipe's leaking, you've got to remove the bolts. But if the pipe's leaking, is good chance the bolts will break. As much as I don't want to do it, decided tonight I am going to take intake manifold off AGAIN and replace my bolts with stainless steel studs and nuts before same happens to me. Will replace water pump mounting bolts too. A little inconvenience now may be appreciated in the future... Anyone want to buy some of my left over drill rod and nuts?
