Those sleeves are installed at the factory so I very much doubt that case made it past QC at TM, also the OP said the engine is a Swedetech, so again it would not have past his QC either. My guess is that something went wrong when the bearing was knocked out without preheating the case, they are in there pretty tight. In a perfect world, yes I agree the sleeve need to come out and the bore should be checked for round and if need be, rebored with new sleeve installed, but I would try to install an old bearing and have a look see and check for gap between the sleeve/case and the bearing/sleeve and if no gap is present, the case can be used as is.   JMHO
