My wife and I were at Buttonwillow today and when the track wasn't wet from rain it was a good day. Until, that is, my wife came of the track and the engine sounded like a garbage disposal. She had not noticed the sound (had her helmet on) and did not notice any loss of power during her session. I had her shut it down to take a look and there was nothing obvious. No oil leaks, holes through the case, gears on the ground, etc. So after a visual inspection, I had her try to start it back up and all the happened was the starter screamed in protest. The engine did not turn at all. I tried to turn the crank using a socket on the fan nut but the pulley just slipped on the crank pulley. As the car was running when she came off the track and then appears to have seized up after shut down I am thinking a chain came off. Any suggestions?
