Hi Stephan,
This is interesting.  I wonder how this is happening and whether,  maybe, it 
is a common event.  It happened to me on my last rebuild, too,  but I didn't 
think much about it until now.  I suppose that iron  (and  maybe alum too), 
particles bypass the oil filter under cold starts and thick oil  conditions to 
settle-out and lodge in the cooler. They then, probably, cause no  damage as 
long as the cooler is not moved. But removing the cooler, cleaning it,  and 
moving it around dislodges the particles and frees them up to cause  trouble.
 
Has anyone else encountered particles coming out of a cooler after being  
cleaned and jiggled?
 
Regards,
Bob Helt
