Yes it does, and very well. Do not do it unless you completely understand what your doing. I run them with 3qts of diesel, you can ad trans fluid to the mix as well for a better clean, but the engine idles for a couple mins watching op gauge, then I slowly bring it to 2000 rpm and hold it for around 3 mins , then slowly bring it down and shut it down. You want no load with diesel in it, it cleans but really is only providing lubrication in the form of being a fluid barrier, so you dont want quick burps of the throttle as you could easily knick a bearing. Diesel has come out black as coal when done. The av I just added oil, drove it 500 miles and changed oil again.
