This question is purely acedemic but could someone explain how this happens? I can see a couple scenarios where the cam would jump a tooth like bad replacement job or turning the motor backwards. But how do I account for the seemingly 1 tooth off IP and the 1 tooth off Cam? Could someone have replaced the timing chain and had it come off both those gears? I guess Im just trying to find out what sort of monkey business could cause these symtoms in case there is something else thats been hamfisted.
