I'm looking for some help in diagnosing the early stages of black death. If the injector seal begins leaking, where does the leak occur? Also, what does the black sludge consist of? Just a mixture of fuel and soot?
I think the injector wells on my sprinter are pretty clean, but the #3 and #4 wells are somewhat dirty. The #5 well definitely has some shiny substance in the bottom of it. Based on the location of the dirt, I think that it may be a leaking air/oil separator. I got that idea from this thread:

I think that if the injector seal were leaking, the filth would be seen higher up on the injector.
The engine runs great, and I have not noticed any adverse smells. You can definitely smell that the van is running if you are in the area, but I think that is common for diesel engines.
What do ya'll think? I greatly appreciate your advice here, in addition to the extremely informative posts which fill this forum.
