Andrew, there use to be a lot of Guru's on this forum that could answer your question. I would say that if you spent just a little time doing some really basic search on the "Diesel" part of the forum, you would get more info then you could read in an evening. I don't have an answer except to say that at 79 years of age I would be scared to death of messing with the IP. It is very critical, but we have guys that can do it. Just go to search and find them!
