My timing belt went @ 26,500 miles. Not pretty. Cruising along
in 6th @ 2800 RPMs just puttering along the interstate. Heard
it go, before I could even put in the clutch the pistons topped
out. Needed nearly complete rebuild of the engine, one turbo
replaced and the waterpump. The service techs were fairly
stumped. Their best guess was that it was actually the water
pump that caused the problem. From how mangled it was, they
guess it seized and the belt snapped.
