I have recently started to pull the engine apart. It is at my mechanic/good friends shop. We went to pull the pulley off the crank, and there was no nose bolt. He seems to think it has been broken off. Another guy I know told me that there was never a nose bolt and that the straight 6's had the pulley pressed on. Anyone know the right answer?


What have I gotten myself into?
