Thanks for the advice about the block drains. I went to Access Freightliner, the only source of diagrams that I know about and was unable to identify them. That is not surprising since the block drains are probably a feature that would need to be described by Cummins.
Can you give me any guidance about a more specific location for the block drains? Having a picture or two of those drains on a 5.9 would probably be of great benefit to several of us.
