270k on odometer two weeks while parking car at home I heard a rattling noise simular to a loose cat shield. My first thought ps pump disconnected belt noise still there. While thinking whats next alt belt comes off. At this point i notice pulley wobbling. loose bolt previous owner replaced timing belt i suspect bolt not tightened to specs . After buying new belts, crank holding tool and tightening bolt to correct specs 181 ft lb iam back on the road. lucky it didn't happen on highway or far away from home.

 

Yea, sometimes being lucky is all that counts

I would re-check it in a week or so just to be sure it is staying tight.
