Big problem with walnut blasts on the oil burners is that its an ugly situation. You don't know what you're really getting into, till you get into it (make sense?) Is it going to be a 4 hour job or a 12 hour job? Will the intake have to be sent out to get boiled out and swirl ports pulled apart or no? Is the associated things around the valve cover going to fall apart or no? Will the runners be filled with diamond tough carbon and take forever or will it be nice and sooty?
Work like that is really hard to get even close to the correct numbers. We always go 0-6K depending on how crazy it goes (up to pulling cylinder head).
Yes that's nuts. Yes I've done it at the dealer per the FSC. Yes, I've hated my life doing a few diesels.
hope that helps
