Mine ran just fine. The upper part where the " half moon eclips " used to be was sheared
off. The bottom half of the shaft where the gear is for the oil pump was still intact and
turning. the shaft snapped in the middle of the bushing. there are two bushings on that
piece. One under the oil hole and one above the oil hole at the top. As long as the shaft doesn't snap between the bottom of the cam gear on the syncronizer and the top of the oil pump drive,about 2- 1/2 inches in length the motor will never shut down because the oil pump is still being driven. The bottom part of the pump drive sits in the block, the other bottom bushing. there is no place for the shaft to go. The only thing that will shut down the motor and ruin it is if the roll pin breaks that holds the cam driven gear to the syncronizer shaft. That will shut down the oil pump. the older engines, The flat head, 235.5 chev, and there are 3 others i can't remember, have the oil pump drive the distributor so when the oil pump seizes the engine shuts down immediatly. No damage. the Vaga had an oil pressure switch that if the motor lost oil pressure the engine shut down. Too bad they don't make them like that any more. Maybe that is a good thing ?
