If smoke is white... its UN-burned fuel or coolant. If black, it's usually burned fuel without enough air in the mix.
Buzz test? That test tells you of an electrically malfunctioning injector and could point to the injector giving you fits. Normally a failed buzz test leads to injector replacement... cheaper then a diagnosis from the dealer and normally on the mark.

Could very well be an injector and the ONLY way to know is to have it checked both at dead cold and hot with an IDS non-compensated cylinder balance test. I know someone who went to a Ford dealer and said they did the IDS test, but didn't. So I would make sure you get a screen grab of the tests.

always wanted to say that, makes you feel like a pirate.
I agree 100% that test is the ultimate test... but a buzz test will get him headed in the right direct to indicate an issue with injectors, would you agree?

Sometimes. My AE test showed no issues. No codes. Buzz was fine. I spent a lot of time through all this, money (FICM tested and poorly upgraded, another story), frustration, and worry that I did not need to. In frustration I bought the IDS and it immediately showed the faulty injector. I just would not want to see someone else go through that so I immediately go to the IDS to determine a solid answer about the injectors.
Watching white smoke coming out of the tailpipe and waffling out at stop lights gets a 6.0L owner in a bad state of mind. My two white smoke experiences have had to do with a faulty EGR valve that looked good and cleaned but was still at fault at cold startup, and the second was an injector that showed no other signs, with the exception of cured stiction with Archoil 9100. Injector changed, no more stiction.
