please help!!
Hopefully, your crank isn't damaged, but it's probably that the old rope seal just gave up.
You will appreciate those rear motor mounts, so you don't have huge crossmembers blocking your access to the pan.
The rear seal is in its own cap, so you don't have to loosen the mainbearing to get the job done. (This is something that I love about the Y Block -- that's how engines should be made!)
Finally, make sure you get a new neoprene seal, instead of one of those ropes, and you should be able to slide the upper half in place, once the rope upper is removed. The bottom, of course, will be a cinch. You'll need a new pan gasket too, of course. The cap that the seal fits in also has side seals that should come with the rear seal, along with instructions on how to get them to expand.
