New head bolts & cracked blocks

[bmrfamly <bmrfamly@xxxxxxxxxxxxxxx>]

Gentlemen
   I'm finding many cracked Blocks on BMW motors that have had the 
head bolts replaced.  Most of these are because the bolts were 
replaced without removal of the cylinder head.
   Many of the headbolt holes within the head are oil filled and 
changing the bolts without removal of the head allows oil to get into 
the bolt holes of the block.
   I don't know any way to sanitize the bolt holes in the block 
without head removal.
   I'll just keep changing blocks as people crack them, but I find it 
a terrible waste.
