So I decided to do a full rebuild of my B275 engine and after pulling the first 2 cylinder sleeves l have found hairline cracks at the thinnest point between cylinders 1-2, 2-3 and 3-4 (see photos). I have little experience with these engines and rebuilding in general so I'm looking for advice from those with more experience than me in this field. Maybe this is normal on the BD144 engine?
I'm thinking that once the new sleeves are in place and the head gasket is in place, these cracks will make little difference but I could be very wrong. If I am wrong (its not unusual!) are there any other options or is the block scrap?
