It's simple
the serp belt breaks while the engine is running. with LUCK, all the debris
falls clear of the crank pulley and no harm done. Murphy, howeve, frequently
f]prevails and allows some shreds of serb belt to get involved with the
crank pulley thus displacing the t/belt and VOILA, crank timing is
compomised.
