Early engines had a looser fitting sleeve than the later engines. Some sleeves could be installed all the way in with just hand pressure. The sleeves are held in place by the head gasket instead of friction in the block bore. Most of the time you are better off getting the .002" oversize sleeves and then honing the block a little if they are too tight. If the sleeve flange height varied too much between adjacent cylinders it could allow a low low sleeve to move in the block. There are shims available to adjust sleeve flange height for these early blocks.
If ether was improperly used to start the engine it could also lead to cracking of the sleeve flange. Ether should not be sprayed into the intake unless the engine is already cranking over and never used if the glow plugs are being used. This type of breakage is not unusual with engines that have seen a lot of ether to start them. You will also find it in the later engines with the press fit sleeve and in the D361 and D407 engines. Sometimes when a head is removed you will find evidence where a piece of sleeve flange has broken off and left it's mark on the piston and head.
