That worked and the engine fired right up but alas without oil pressure. Finally we discovered that we had spun the oil pump drive gear on the cam shaft. I suspect that you may have done the same because of the washer stuck in the o.p. gears.

yes, the gear that drives the oil pump is not turning when engine is turned over, so now the cam needs removed to repair this ? also the oil pump wont turn by hand after I cleared the lock washer , I believe one of the shafts the gears run on is bent also
