Black death from dodgy injectors.

[BOB B]

My sons had a problem with a Mercedes van he bought a few months back so we looked up the symptoms on the net and came to the conclusion that it was a problem with the injectors which caused a thing known as "black death".

Anyway this week was the first period of time I had to look at it, well.... , took the manifold and air pipes off then the engine cover, (which was stuck on) and found this.

 

Now I'm no expert, and I have never seen anything like this, but I reckon it's pretty terminal, half of it is like solid plastic and the rest crumbley plastic.

 

Anyway here are a few photoes, any comments or constructive Ideas welcome.

It is carbonised diesel, try and clear what you can. To get it off you need a solvent which one is up to you I have heard some use nitromoors, coca cola.

 

You will need to reseat all the injectors as well, like you said this is a fairly common problem called black death. There is loads of info on the net about it.

Hi thanks for the comments, in the end I used a combination of Coke, drain cleaner and whittling with four different screw drivers to get the "BLACK DEATH" out, took just over 9 hours.

 

The other reason I'm back is, I hired A tool for removing the injectors one part removes the top half, and the second part should screw in and then a reverse screw out to pull the rest of the injector out, as you can see from the pictures there is no where to screw down into, and the bit you see in the way does not come out.

 

There is supposed to be technical back up from the hire company but I get no reply there, just wondered if anyone can help.
