Just so I have this right: You have fitted a 'seal surface saver' type sleeve to that area of the flywheel end of the crank. It is 0.080"[eighty thou?] larger in dia , that a huge dia increase to expect the std neoprene seal to work with and even the existing seal groove in the block would need a rework for crank & seal clearance. Sure you dont mean 0.008" [eight thou]. The 351w/c cranks are larger in dia, but you would need a major rewok of the seal groove & crank to make that work. Might be leaking threads as Jerry mentions, but better get a handle on these dias first.
