Hmmm =E2=80=A6 that= =E2=80=99s a scary thought, as there are 15 other bolts in question.  = Either this one was lighter coated, lighter tensioned than the rest or the = others are also in jeopardy.

I put a heavier sp= iral on the replacement bolt, which is also larger in diameter.

Looks like you needed to be much more generous with the= RTV when installing.   It should look a LOT messier than what yours l= ooked like.   There needs to be enough to smear off on the housings wh= en installing.
