Imagine of shells. From rod 3 and 4. Definitely more wear to these shells, which coincides with pickup on bearing faces 3 and four, ... Would be interested to hear if this is typical of csl or std m3. Other rod shell don't look to bad, and this coincides with other crank bearing faces being fairly pickup free, ... also noticed most of wear appear to be or the rod shell , bottom shell definitely have less wear in general, ... pictures shows rod 3+4 first. I've definitely seen shell bearings looking a lot worse, so can only imagine once you can see the copper colour on shells there will be a fair amount of pickup on crank faces, pity BMW don't do some kind of temporary shell that can be fitted to polish up crank faces and be then removed......Hopefully of interest to someone
