By the looks of those bearings the crankshaft can't be in much better condition. The top end would have suffered also. Once the oil thickens up and turns to sludge the oil galleries start plugging up starving the motor of lubrication.
Now I wonder if the owner will take better care of the Econoline van after this, or maybe they just had $3000-4000 they didn't have anything better to spend it on!
Was this motor still running when it came into the shop or was it seized up already?
