Cam has walked back into the block about a quarter inch
what happened to the timing gear-did the cam move 1/4" deeper in the timing gear and block or is the shaft flush with the gear and the cam/gear both moved 1/4" closer to the block.
At the back end of the block is a "freeze plug" looking device that is supposed to keep the cam from moving deeper(rearward) I hope it has'nt "popped out!
If cam is 1/4" rearward, then the distributor gear may not even be engaged with the cam (this means no oil pump being driven either). Good reason for not starting.
