Hi Panzer, are you still with the black smoke?
To clean the turbo well, the good would be to disassemble the engine and clean the compressor turbine with diesel and a brush, ensuring that it does not between the lubrication tube or the exhaust turbine.
After having cleaned it, you blow it with compressed air and by the greased racor you put a few triggers with the oil and normal engine oil (to remove the diesel from the axis bearings).
You ride it and keep the engine over 1500 rpm for a minute, so that all the diesel that could have been on the escape side and in the admission snail is evaporated.
The intercooler, you can submerge it for several hours in gasoline, solvent, diesel or water with detergent (motor cleaner).
Eye with the causic soda because aluminum is eaten.
When you get it out of the "bath" you clarify it well with water under pressure, and if you could wash it with a pressure water hydrolavator it would be no more.
But above all patience to disassemble the car pieces and reassemble them.
If you do not want them to be dirty again, you can redirect the tube of the vegetables of the crankcase to the ground although it is not an idea that I like because it is quite polluting. (I wouldn't).
Greetings companion!
