if you have a experienced crew a sleeve swap can be done before the block cools. the first thing that is done to my car after a pass is a leak down and plug inspection. this will give you a good idea of the health of the engine. to get a idea how much a aluminum block grows due to heat i set the cold lash at .016 because hot it becomes .026 a iron block won't do that. the sleeve bores also expand when hot. thats why the sleeves can get pulled out. the sleeve bores are honed to size. trying to remove them cold is not only hard on the crew but also hard on the block. the bores could be damaged. if a sleeve needs to be replaced its all hands on deck for a crazy well choreographed thrash.
