I think that the sleeves slide up and down outside the liners, The pistons run inside the liners which have slots in their sides, and the sleeves - also with slots, slide outside the liners. At certain times during the engine cycle ,these slots line up ,hence the valve effect.
These sleeves therefore must be an excellent sliding fit between both the liner and the outside finned cylinder block/head.
As far as those Clayton lads solving the early seizing problem, perhaps thr sleeves were brougt in for final lapping at Clayton to finer tolerences.
