So I was trying to change the seal on the fan Hub, Big leak, when tring to remove the fan hub from the crank it required a puller and an indordinate amount of pressure to break free. Once it had broken free I found that the crank keyway had sheared and was in two pieces. This had happened prior to our buying the car but is one more thing that has shown up during the Tune-Up (IMG:style_emoticons/default/headbang.gif) and leak fix that keeps growing with leaps and bounds (IMG:style_emoticons/default/chair.gif) . any Ideas on cause?

. any Ideas on cause? As to the cause: Mine had the alternator belt work loose, spin off of the alternator, twist into a figure "8" and hang up on a bolt while flopping around, bringing the engine to an immediate halt. (OK, this was all helped along by an off-track at turn 1 Summit Point after overcooking the entry.....but I digress) Actually didn't shear the key, but certainly could have. It just pranged the allen head bolts holding the fan to the hub enough to screw up the timing (I'm on SDS with magnets in the backside of the fan) and lead to lean running, engine failure and a rollback ride costing $150 for one mile of transport.
