I checked both my 351M and 400 dist. the rotor does move back in place after turning it against the wt. springs. I forgot to mention this earlier.. underneath the rotor should be a felt pad, under that a clip. When doing points part of the maint. was to put a drop of oil on the pad and shaft to keep things lubed. Electronic ignition sort of put a stop to that service job. Lack of lube could cause your problem.

There are metal shavings stuck to the pickup down in the distributor. Wonder if that has anything to do with it.
So I guess Ill be picking up a remanned distributor this weekend. How do I line up the teeth on the new one so it lines up right?

Mark the exact location of the rotor. I mean EXACT. that way when you install the new one you put the rotor to the exact same spot. If the distributer doesn't drop straight in you may have to turn the Oilpump driveshaft which is inside the block and inserts in the bottom end of the dizzy shaft.

Got the old one out, gonna take it to Autozone in a little while. I've noticed that when I turn the dizzy shaft, theres a clicking sound coming from the distributor body. Sounds like a messed up or broken springs. Only reinforcing the diagnosis

The dist may not be all the way down into the oil pump drive, the dist gear drives the oil pump through a hex shaft. I hope the shaft did not pull out of the pump when you pulled the dist out (there is supposed to be a "keeper" to keep the shaft from coming out). When installing the dist sometimes you have to bump the engine a bit to get the drive gear and the pump shaft to line up.

Does this look right to y'all? In case you cant tell, the hex part is recessed about a half inch.
But mine looked more like this:
I have a feeling I'll be calling Autozone later
