My picture is an engine that was bored out and a metal sleeve installed. The sleeve has a lip on the top that fits into a grove machined at the top of the cylinder. The lip keeps the sleeve from being pulled down. The sleeve can't move up because of the head. The sleeve looks like this.

The lip breaks permitting the sleeve to be pulled down. Then the top of the now broken sleeve gets caught by the piston ring. This pic is the broken off lip from another sleeved engine.
I think the silicon liner/sleeve is very different and not a true sleeve. It is some fiber material with 25% silicon and the rest air. When the metal is poured in the mold the sleeve goes away and all that is left is the silicon that bonds to the cylinder wall and becomes part of the metal. I do not see how there is a "sleeve" that can move.
My drawing of a sleeve went out of wack when the message was posted. Looked good when I typed it.
