Definitely call the machine shop and ask them how well the block and crank were cleaned. My machine shop tells me - "clean it" because he is a one man show and while he cleans cranks and blocks after working on them, it is mostly a manual process and he wants the builder to double check his work. In shops with automated cleaning equipment, I think the risk is much less. "Squeaky" clean is an excellent indicator - I would not worry but I would give them a hollar! Thanks for the comments!

Don McKeown Sorry about your loss Don. As for the spent brass, how about melting it down into a plaque - ala a lot of post war rebuilding centers, that could honor Grampa and you and your son's restoration efforts? Alexander's work is impeccable!The engine assembly process is great fun. The next episode is going to have more things to pay attention to....like setting end play on the crank and cam, etc. Very satisfying work!
