   Thanks Randy, that makes sense, as it seemed strange to me that the engine would have so much oil stain, when the boiler and the rest of it shows so little sign of being used very much. Looking at it closer, it looks like underlying rust is the issue, I might try to clean up a bit more and see what happens but I won't push it. In normal light it looks pretty good already, I would not want it to be mistaken for a re-paint! 75 Jensen engines is amazing!
