First of all- thank you everybody who was able to provide input- Not sure why I was so freaked out by the process of changing the rear seal- It's done now- After pulling the bearing cap- the upper seal half slid out kinda easily- Sliding the new one in was a little bit tough but now that I think about it- it should have been. bearing cap was re-installed after the bottom seal was installed and torqued to 70footpounds- Here is what the old seal looked like:

and the new one:

and the old one being slid out:

as I look at the old one- it looks pretty good- not sure if this was the source of the puddles under the engine- but at least I have a new seal now... tomorrow we tackle painting the block and engine items that get painted the same color as the block...going out to continue cleaning it now...
