Well...the unthinkable happened today in my S/C 4Runner. Went to pass a truck and had no power. Pulled over thinking I had thrown a belt since I lost my power steering, and found the main crank/dampener pulley resting against the fan shroud. Apparently the bolt came loose, and in the process sheared the woodruff key down and shaved the crank down to the point to where there is no place to even insert a woodruff key anymore. Woe is me...woe is me. Minimum, looking at a new crank. Might as well go ahead and replace the entire long block if I'm going to go that far into it. Engine still ran great and unbelievably fast with the supercharger at 217,000 miles. Shame it had to go over something so minor. Can't think of any other way around it.
