If I am not mistaken, there are small hole at the bottom of those units for water drainiage. Is that where that tiny bit of soot is comming from?

- That looks like something barely leaking to me as well... not enough to cause any issues... but of course, the Stealers$it is going to tell you that it needs replacing no matter what if there is even a hint of soot... that is their job!... due to liability, because if fuel from the doser injector collects and gets onto the outside of that unit, then it ignites... truck has chance to burn to the ground. That, and if you fall alseep at the wheel one night and kill yourself or someone else.. and carbon monoxide is found in your blood.. that stealer#shi#t would be responsible if it had recently been worked on. <- Like I said... their doing their job... they make the most expensive call on it, that is how they make their moneys.

- I would say that your problem is that you took it to them to begin with. Should have pulled the units yourself and taken them to have baked, de-ashed, flow tested and called it a day... making the decision you own if you want to replace it due to what looks like to me a tiny bit of soot from the weep hole in the bottom of it (or a tiny stress crack that can be welded up in 2 minutes).... but that is just me. Anyone with a welder can fix a tiny leak like that in no time vs. nearly $7k for a new one if the element is still good.
