The difference is that the Nikasil corrosion is a well-documented, and 
easily-diagnosed design problem.  It has been written up in the Roundel, and 
in at least one other national car mag.  There's no question that many people 
on this list are very well informed about BMW issues, however I think it's 
presumptuous to think we're the only ones who are aware of this issue, as 
someone has implied.
 
A cracked cylinder head and a bad camshaft can be caused by any number of 
reasons, and it is difficult for any owner to disprove that they were caused 
by inadequate care or maintenance.  Please note that I have no information 
about the iron-block-6 cases you mentioned, so I am certainly not suggesting 
_that_ specific owner maintained his/her engine poorly.
 
I think my original point is still valid, i.e. unless there have been 
instances where the _modified_ engine has developed the same corrosion 
problem, why get alarmed.  If you own one of these engines, maintain it
properly, and hope for the best.  If something goes wrong, _that_ will
be the time to get worked up.
