Thank you, Stuart. I'm still trying to visualize this. Your previous post is helping, but I don't have a good picture in my mind yet. I'm re-reading your post a few more times.
I ruined the tube that is inside the water jacket. Replacing it is what I am obsessing on. The part under the side panel that runs up to the rockers is easy.
You wrote: "The fitting underneath the side cover that screws into the block is factory soldered to the tube. The tube is inserted from this side and screwed in tight. The other end poking through the lower side of the block is now sealed with an adapter fitting and a double compression fitting. It will become water tight."
To do what you wrote, which seems to me to be what I need to do to replace the "inside the water jacket" part of the oil line, wouldn't you have to drop the oil pan to get to the fitting on the lower side of the block?
The part that can be replaced without taking off the oil pan is just the part running from the side of the cylinder block to the rockers, isn't it?
To replace the 'pigtail' that is inside the water jacket needs the oil pan off, correct?
Thanks, Stuart
