2006 F-350 diesel V8

[Jakewith72as]

Does anyone else with an 06 F -350 with the 6.0 diesel have black smoke problems when the turbo gets above 20psi? I har this problem when all the time not just towing and it doesn't seem to me to be large amounts of smoke but i would say it is a clearly visible amount. Just wondering

Black smoke would indicate too much fuel or not enough air.

I known that, I have been told by three different people now that it is common and I need not worry about it. And I just don't believe that it is nothing.

Is the boost pressure going up in a linear faction against the throttle or a step function and are you hearing any turbo farts, pops back through the air cleaner?

If these are present your turbo inner ring may be sticking.

My 6.0 does not show any smoke under any condition.

Black smoke is clearly over fueling and not to be expected from a stock toned engine.

This is a good source of information.

Everything moves up slowly the way it is supposed to and no burps or pops, it's got me scratching my head. I have asked two mechanics and a couple friend that have diesels and am getting mixed results. Thanks for the help

Common issue with the variable geometry turbo on the 6 liter. Query the internet for more info on this turbo.

Black smoke coming out of a 6.0 will mean death to the turbo pretty soon. At best the soot will clog the vanes on the smaller of the 2-stage turbo. Something ain't right and you better get to a dealer quick.......and trade it off.

I would check the warranty on that engine. The government has imposed strict requirements on diesels. The pump on my Suburban was covered for 120,000 miles and my 6.0 Ford was fixed at NO COST even though I was the third owner.

Don't ask a "Stealer" check it out on the web and go in armed.

The Power Stroke engine, regardless of species, like the 6.0, has a 100,000 mile warranty and 5 years, which ever comes first. So, if you are within that 5 yrs/100k then you should get dealer warranty work regardless if you are the original owner or the 10th owner, doesn't matter, just the mileage and age of the engine.

Yep, I am outside the five years, but still under another warranty, dropped it off today and they think it is a stuck valve but not sure yet, will let you know as soon as I know anything
