I got my engine apart, the rear seal was pushed out of the block up against the flywheel. There is nothing wrong with the seal. The clutch housing still had about 4 quarts of oil trapped in it. I guess my idiot light for oil pressure didnt work so there was no way to know the oil was all pumped out until it was too late. The damage looks to be 1 connecting rod journal on the crank.it didnt spin in the rod but did damage the crank. So ill get the crank reground put in 1 oversize bearing and replace the rest. Also have to replace the clutch disc as it got a pretty good oil bath. My local Agco dealer says parts are all readily available from the warehouse in Batavia Illinois. I am going to see if there is a way to lock that seal in place to avoid this again. Has any one else had a similar issue?
