Keith,
I agree with kevin. I think that without the crank nut, the force from the bevel cut gear just pushed the crank gear forward enough to disengage it from the key. Actually, if you are just wanting to rotate the cam by using the starter to crank, just push the gear back on the keay and align it anywhere, since you probably should not run the engine any more until you determine the cause of the noise.! Then you can put the nut back on, with the cover off. Since it ren before, you should be able to discount a broken cam, but you may have a damaged one, or damaged lifters.
Maybe the noise is caused by excessive play in the cam "bearing" surface in the case. Maybe something plugged an oil passage and caused the cam to open up the holes it rides in, thus causing it to wobble around in the holes and the lobes hit the lifters out of alignment.
Lots of possibilities, but sounds like you've narrowed the area down. Good luck!!
