DPF- White Smoke

[mdbreaux]

2006 F350 6.0 with white smoke billowing out for about 30 days. It was intermittent at first and I had Ford do an EGR replacement and BG intake cleaning and pressure tested the EGR cooler and all was fine with that. They said no bad coolant or indications of bad head gaskets. Now the smoke is constant and large amounts of white smoke. It smells like faint burnt oil, but not blue smoke with no strong oil smell. I believe it is eiahter turbo oil seal bad or injector bad and placing oil in cylinder or overfueling cylinder. ANy suggestions? I have 49,000 easy Highway miles with no towing. My plan is to undo turbo downpipe clamp and inspect turbine and downpipe for indications of oil. Then, I will try to figure out how to test for a bad fuel injector. What the heck is "regeneration" and "DPF." Thanks for any HELP. Michael.

White smoke is overfueling of the motor......regen and DPF has to do with the new 08 emissions on the new 6.4 motor. Regen is short for regeneration mode which is a process thats cleans out the DPF or diesel particulate filter of all the soot that it has caught from the exhaust

I am having the same type of issues with my 2006 F350 6.0.

It started recently (past month or so) where I have a large puff of white smoke coming off idle, like pulling away from a stop light. I have the smell of burnt oil coming from the engine as well, but can't find a leak all I have is the (what I would call normal / dirty light oil spots)

I have 47000 miles, a 4 inch exhaust, deleted cat, Evolution II programmer, Air Raid intake. Use the truck to drive back and forth to work (desk job) about 20 miles each way mostly highway.

MPG is about right, acceleration is normal, nothing seems out of the ordinary except the smoke.

Now the bad stuff... I haven't changed the oil in about 7500 miles nor have I had the fuel filters changed since I have had it (approx 22000 miles). Bought a filter from one of the sponsors on the board.

Now my questions..
1) Anything I should be CRITCALLY CONCERNED WITH?
2) Will the warranty cover items like this (believe the engine / tranny warranty is for 100k)
3) Would you pull out the Evo II? (it is kinda easy except the pyro cable)
4) Lastly, anyone recommend a better Ford repair center in the Nashville / Murfreesboro, TN area

Thank you all in advance !

Hi folks, I'm new to this forum. I just found it.
I'm a tech at a Ford dealer. I just had two '08 6.4s in for coolant loss. One was a hose leaking externally, nice quick fix. The other blew the horizontal EGR cooler and hydro-locked the engine. When I did get the engine issues sorted out, it blew huge clouds of white smoke while it cleared the coolant in the tailpipe. It wasn't overfueling.
Have your cooling system checked if you're getting white smoke.

on another note: since a diesel has no throttle, if you add more fuel, it should go faster. if you add it at the wrong time, it will blow black smoke, no?

......very true as far as the black smoke, however when my truck was stuck in regen and I didn't have the DPF or cat on there I was blowin white smoke everywhere.....it was insane

White smoke is diesel that did not burn. Black smoke is from an incomplete burn due to a lack of air. The black smoke is hot whereas the white smoke is raw fuel that never got hot enough to burn.

Water vapor dissipates very fast, fuel or oil will not and have a tendency to linger in the air with a distinct smell of fuel or oil. Antifreeze also has a distinct smell.

Lets say your cruising along and raw fuel is depositing in the exhaust somewhere. Then you get on it and the heat finds the raw fuel and you get a lot of smoke. This would be white smoke as it does not get hot enough to get black smoke. Seems like a temporary injector problem or regen cycles could cause this to happen under certain conditions.

What if water gets out of the exhaust. It would tend to cool the regen fuel and cause it to not all burn off as intended. Then you have a mix of white fuel and coolant water. If this happens I would say there would be milky fuel leaking out of the tailpipe eventually.

If too much fuel is deposited in the regen cycle it cannot all burn of if there is not enough heat and you get a lot of smoke. Lets say your hauling *** and a regen starts. It dumps a lot of fuel into the exhaust. At that same moment you come up to some traffic or something and end up idling along for a while. When you take off again you might see a lot of white smoke.
