If you do this with the motor assembled, how do plan to keep the abrasives out of the oil galleries? Answer is, there is no way to do it. One little piece of that red stuff (pictured above) or Scotchbrite gets in the gallery, and it'll screw things up real bad.
Yes, I agree, just part of building motors...that is why you per assemble EVERYTHING, and check everything. My last motor went together and back apart 4 times before all was said and done...isn't building engines fun?!?!? lol
