So i was just driving going 40-60kph when out of nowhere i hear a loud BANG. pulled over immediately just to see the pulley literally rolling down the road beside me. The car still ran, lost power steering and alternator. grabbed the pulley and went home immediately. My guess was the bolt backed out but how.
Next morning i went to inspect the damage and found i tiny chip on where the woodruff key sits. Made a video and the scratch noise you hear is the timing belt guide cover loose. I just hope nothing internal was catastrophically damaged. i’m gonna check the timing soon. Is my crank still good? i’ve heard about people using JB weld to fix it.
