I thought it was the nut that was coming loose. It turns out the stud will not stay tight resulting in a leak. What can I do to keep the stud in tight? Would it be too hot for locktight? What are my options other than tightening it down till it breaks. (IMG:style_emoticons/default/confused24.gif)

The Cap'n may be right. If the stud pulled out of one of the inner bosses (closest to the center of the engine) then it is entirely possible that the stud pulled out because of a crack. They radiate from under the ex valve seat out to the stud boss. It's pretty obvious when that is the case as you can get a good look at once the exhaust is off. If that is the case it's time for the heads to be re-worked, or tossed.
If it pulled out of one of the outer bosses the likelyhood of a crack precipitating the failure is extremely remote. |
