I decided while I was doing some other work to see if a new rope seal would slow down the rear main leak. There was a neoprene seal that had been leaking for several years. I removed it and cleaned up the surface of the crank under the old seal with 600 grit paper and flushed it with carb cleaner. I have a new Best Gasket rope seal to install. I plan to pick up a Sneaky Pete tool tomorrow. I've loosened the other main bearings 1-2 turns but I can't get the crank to drop any at all even with prying. Any suggestions? Looks to be difficult to get the new seal started without a little extra clearance. How much can it move without damaging the front seal and the transmission input seal?
