Black smoke from a diesel **IS** unburned fuel. There are only 2 causes, as
already mentioned poorly atomized fuel from fouled spray nozzles / injectors
is one. The other more likely cause is insufficient air to the fuel burned,
try not to think air fuel ratio as it doesn't really apply, we always prefer
excess air on a diesel. Most likely cause is a dirty air filter or other
restriction. On a turbo diesel an air leak downstream of the turbo is a
common problem. A faulty turbo may not be producing the boost required.
Start with the easy stuff first. I would not go pouring water thru the
engine as it runs if that's what you were asking. 
Side note, I tried the acetone in fuel trick on my Nissan commuter car
(gas). Very carefully noted the mileage over the same course for several
trips and saw exactly no difference. I figured it was a hoax and I was dumb
enough to try it. 
HTH, Tim Andres

Buly,

water IN the injectors is pretty unlikely - I use and actually change a fuel

filter regularly - The Toyota filter is made to seperate water, never any 
problem.
However if you imply water drops hitting the injectors....
Anyone else?

Thanx Buly,

TJ
