Engine rebuild update. Good thing I have two feet cause I keep shooting myself in one of them.
After I split the case, I saw I was wrong about about the oil slinger breaking. It turns out that there WAS a washer behind the crank pulley for some reason. The pulley wasn't a sand seal as far as I could tell (had reverse threads). The slinger was intact and didn't show any wear.
The shot to the foot was a ground up brass timing gear from failing to remove the distributor drive when I plugged the distributor hole. I now am very aware of what happens. Fortunately the steel crankshaft seems to have ignored brass. The front bearing surfaces showed some light scoring so I probably caught it early.
In any event, a full set of bearings, sealant, gaskets, studs and seals are arriving this week. I also ordered. 12" long 7/32" drill to do the Hoover mods for the case.
