Here you can see they were worn beyond even the "used limits".
Needless to say, we are looking into having new rings made. This was causing the crankcase to become pressurized.
I was also worried that the water jacket was leaking. But on a good note, the jackets held air.
John had to build a special jig to remove the valves.
OK, we are even - one bad thing (rings) and one good thing (water jacket).
Add one more to the bad column. Most of the valve guides were worn beyond limits. We are going to have to sleeve them back to size. More on that later.
John also split the case and measured the four crankshaft bearings:
Add one more to the bad column. The front and rear bearings were fine. The middle two were shot. They were very far out of limits. These bearings are poured babbit and will have to be replaced. We are looking into that process.
Here is a picture looking into a cylinder when we disassembled the engine. Add one to the good column - the cylinder walls were not badly pitted.
The score: 2 to 3
Good - Water Jacket, Cylinder Walls
Bad - Rings, Valve Guides, Bearings.
Hey, we can't end on a losing note. How about a little humor:
Anyway, Dorian Walker just sent me pictures of his Jenny. Thought you might like them too.
More soon. I have a few other things to tell you but I have to run the kids to various functions critical to their social needs!
