Dear Tom,
The tin is cut to size and placed over the journal on the cylinder you are working on. It prevents hot metal and junk from getting on the smooth surface.

The piston is going to react thermally to being melted, so I cannot say how much will be needed to be missing before it loosens up. Do not melt into the cylinder sleeve or you might incidently weld it to the cast iron of the block.

Welding stripes of bead down the length of the sleeve at a reduced low penetration setting, but just enough to keep the arc going, will draw the sleeve smaller when it cools. Do not go through the thin sleeve when doing this as it will (as above) weld the sleeve to the casting.

I would get to cleaning out the crud in the water jacket (under the cover mentioned) to see if the efforts I was going to make to remove the cylinder components was worth it. If the block is cracked around the cylinder castings from the effects of water freezing, or rust expansion, I would get a different block. It is fairly expensive to sleeve out a block to repair a cracked casting.

Good luck, JimN
