Also the newer engines have a better system of oiling that upper bushing that seems to be a problem in the older ones where they oiled it through the crankshaft instead of through the block as on the newer versions.
Not sure what an engine builder would get for a rebuild, but as a DIYer, the difference in cost between a rebuild and a new FH680V is enormous. Looks like a rebuild should be able to be done for <$300 parts & labor for a moderate amount of machining, if required. Of course, if the crank or rods are toast, that goes up quickly and changes the cost/benefit ratio. If it came to that, and as bad as the Kaws are, I think I'd buy 2 lesser-model Kohler or Briggs engines for the same $$ and call myself ahead in the long run.
