'05 CDI injector "Black Death" adventure - Page 2 - PeachParts Mercedes-Benz Forum

A couple weeks ago I purchased an '05 CDI from a dealer in Ohio (I am in CA). I asked them to take photos of the top of the engine with the plastic cover off. Much to their surprise and mine, it had a major case of the Black Death. Knowing this, they decided to wholesale the car. I made an offer that was probably more than they would have gotten at auction, and after doing the "dance" (back and forth negotiations), they accepted my offer. I got a good enough deal (even considering shipping costs) that even if I had to buy injectors or other expensive parts, I would still be ahead. The body and interior of the car is about a 9 out of 10. It seemed to be very well cared for.
So that brings me to today, when I decided to tackle the job of replacing the injector seals. Armed with the needed parts (purchased from Pelican), the reading of several injector threads, and viewing a few youtube videos, I was ready for the task. I have never touched a CDI engine before today, and have only seen photos and videos of the procedure. This one is probably one of the worst cases I have seen, but I knew what I was in for from the start.

After removing the plastic engine cover, I started picking at the black carbon, and breaking off large chunks. Every once in a while I vacuumed up as much as I could. I used compressed air to blow away the smaller particles.
