Thanks so much for the great input. I was kind of thinking that pulling the engine might be a good idea anyway. there seems to be a signifigant leak from the main seal when i am cranking it, and if i want to feel confident in the engine when i am at sea, maybe taking the time to rebuild might be worth it. Im not in a major hurry to get this thing going and the engine looks easy enough to pull. What are your thoughts? btw, I am definitely going to get that diesel book!
