ahh my friends dad is head engineer for United, i was going to pinch some of his tools and pick his brain for the build.
engine assembly really sounds like clean, clean, check, check then check some more, clean everything. and then check again and again. and pray to the gods the machinist got the job done correctly
i'm probably going to reuse my n1 pump that came off my newish motor, the drive is in pretty good conditon (almost new), and i too will not drive like an Gorilla.
