head stud
I have my 3.0 engine out and practically everything of of it, such as induction system, heat exchangers, shroud, and alternator, it's essentialy down to the block. I took the lower covers of the engine off today and what do you know , a F*(&*n head stud dropped out. The question is, can this be repaired by itself or does the entire engine have to be rebuilt? Give it to me straight doctor, I can take it.

I am faced with that as well and have done some research. The head studs may be replaced without doing any other work, but since it requires removing the P & Cs -- at this point you might as well do all the head studs and replace the rod bearings. You may not have any damage as a result of the broken head stud and may have had good compression and leak down.

pistons & cylinders. From what I understand the "short block" without the Ps&Cs must be taken to a shop that can machine the old studs or remnants out. Don't even think about an 'easy out'.

I've fixed three studs with this problem (2 SCs, 1 Carrera). The lower head studs corrode and break. On earlier cars with magnesium cases they would pull out of the case - a much harder situation to fix. To remove the stud, you heat the case to break the high temp Loctite free and then use a stud remover. At a minimum, you replace the lower head studs and the gaskets. The pistons, cylinders and heads must be removed.

Opinions may vary, but there are definitely those who say that a 911 may be driven 10's of thousands of miles with a broken head stud, or two. I did it, no problem. When I did get around to fixing the head studs, I found practically no difference in performance. I had two broken on the same cylinder bank of an '83 SC USA model.
