It would be nice to see you get a response based upon data, but I doubt that a database exists. My opinion based upon my memory of the threads in this forum is that there are many Sprinters running around without any problem with injector seal seat leakage (Black Death).Just trying to gauge the problem. Is the black death something that all sprinters will eventually get if driven enough? Is it a problem more prone to early models vs later models?

Oops. A brief telephone conversation today with a T1N Sprinter owner revealed that just within a few days the seal may fairly quickly deteriorate to a noticeable chuffing sound from leakage. (Possibly a broken hold down bolt?)...
The good news is that if you do a regular (each oil change) remove the black plastic cover visual inspection for signs of leakage, then you will catch any problem early enough that it will not be a major repair. ... Sorry I can't offer more. vic
Its always been specified as 7Nm+90+90 on the OM612 in my ML270CDI. I've done 4 out of the five so far on that.The procedure was to end tensioning with a 90 degree turn to load the hold down, but MB's WIS now specifies ending with 2 - 90 degree turns to load it.
That would explain a repeat failure after replacement, but shouldn't all engines be assembled similarly at the factory regardless of their intended market/destination?Its always been specified as 7Nm+90+90 on the OM612 in my ML270CDI. I've done 4 out of the five so far on that.
I've not had to do a Sprinter injector yet, but seeing as how its also a OM612, I will be doing 90+90 for sure when the time comes. Maybe this is why you guys Stateside have so much black death - someone made a mistake in the WIS.
Are the hold down bolts identical to the ones on the ML270CDI? Same size, length, and part #, do they engage the same number of threads? Is the copper washer the same thickness? If everything does match up to be the same, then it probably is a mistake in the WIS.Its always been specified as 7Nm+90+90 on the OM612 in my ML270CDI. I've done 4 out of the five so far on that.

Nothing personal. Your word is good. I've been reading your posts for quite some time and you have great credibility from my perspective....
But dont just take my word for it. Look at some UK forums, its common knowledge that its always been 7Nm + 90 + 90 on these engines.
I somehow misread what you said here.That would explain a repeat failure after replacement, but shouldn't all engines be assembled similarly at the factory regardless of their intended market/destination?
