[s-cars] Crank Pulley GB

[Tom Mullane]

Just speculation here, but the most likely reason I can see for these
failures is that the crank bolt was not replaced and/or torqued to spec
if/when it was removed for a timing belt change.  Every time I do a belt,
the torque spec seems ridiculously high and it requires a ton of effort to
crank the bolt down.  I would if some folks are going easy out of fear of
breaking the bolt...?

There has been another failure that I am aware of.  A friend who lives just
out of Asheville had failure of the crank pulley on his S6.  His actually
slipped and caused the car to stop running altogether and I hear it wasn't
the easiest thing to diagnose since the timing marks still line up.  I had
mine replaced when the timing belt was done entirely because of his
experience.  I would recommend replacing it at every or every other timing
belt change.  I think his car had 140k miles on it when it slipped.
