Agro: Things are starting to add up a little! in your first post, you said 'cam' was egg shaped. In the second, 'crank'. If they are saying the crank is out of round, than they did one crap job of machine work! NO WAY this should have been overlooked. A machinists job is to check EVERYTHING....twice! If the crank is out of round, no seal on earth is gonna seal it. Maybe this is why they want you to pull the motor...to repace a crank. I still hold to the conviction that a 2 pc seal, installed correctly, is as good as a 1 pc. I admire your conviction that they know what they are doing, after 2 rear main failures on a new motor! I just wish some of the customers I used to deal with in my shops were so understanding!
