Re: She's Alive!!
Those compression numbers don't look so good, there is a significant range. Are the wet and seeping plugs related to the low reading cylinders? The low cylinders may not be firing, or firing intermittently, but they certainly will be weak if and when they do fire. The next thing to check is whether the compression loss is from the valves or the rings. One day on Horse Power I saw them take an old spark plug, knock the porcelain and guts out it and weld an air fitting in the end. You then screw the tool into the plug hole, connect an air hose and look for where the air is coming out in order to help diagnose the potential problem.
