I am new to this site and I just bought an 05 6.0l PSD. Great truck I will post some pics.

But to get to the point a guy I know has an late model 03 with the 6.0l PSD with 150k miles on it. It started out popping and blowing Black smoke between 70 and 80 mph. Now it does it when all the time. He has had it in the shop for about two weeks and he recently picked it up........Still has the same problem.

What should he look for to solve to problem or what could be the problem?

Anyone think they can help solve this problem?? Please???
