Install a repair sleeve on the damper hub....
Use a quality seal....
If the front cover is not pinned, move it around until you find the same distance from the crank snout all around the seal. (block could have been cut on the main saddle in the past, to repair a spun main. This will move the crank up in the block, no longer aligned with the front cover seal). If the cover is pinned and the seal is out of alignment, drill the pin hole(s) a little larger in the cover to allow you to move the cover around a little and align the seal with the centerline of the crank snout.
