The group has given you some good advice on replacing the figure 8s...Be
very careful when removing the liners, they are easy to crack. I used a
4x4 block of wood and a hammer to tap them out, but there may be a better
way.When you get them out, inspect carefully for pin holes in the liners
that can occur due to rusting.In addition to replacing them, I would
recommend having the block professionally cleaned and inspected for cracks
(magnafluxed). Besides good insurance, your engine will run cooler and the
cost shouldn't be much. Be advised, however, that the cam bearings and
freeze plugs will need to be replaced if the engine is vatted, as the
chemicals eat them up. If you had any oil pressure problems in the past,
you probably want to replace the bearings anyway. These are often
overlooked when doing a rebuild.Good luck!
