I popped the freeze plugs out of the engine yesterday as I wanted to clean out the crap in the block and replace the plugs themselves. Wow! I don't think I had ever seen as much sludge & hardened sediment in a block before. I had a hooked awl, and used it to break up the hardened soot. It was coming out in 1" chunky flakes. I got close to 1 cup of compacted sediment and that is just one side of the block!

In my previous posting, I went over pulling the oil pump out. I am contemplating upgrading to the Olds pump conversion that KevinAZ has been posting on his blog. It sure looks good. I might just rebuild the the original in the mean time. If mine is a first generation pump (thanks Packardv8 for the response) is there a benefit in using a second generation or third generation pump instead of the one I have?
