I found this article searching on google Diesel Smoke tells YOU a StoryÖ
As they say white smoke happens when raw diesel comes through the exhaust completely intact and unburned, it ties in with the regen cycle.

Regardless of the cause of the white smoke (water or too much fuel) Iím just glad the truck is still under warranty. I trust the dealership that I use not to blow smoke up my *****.

This in Not uncommon in 6.4s. The reason is because when it starts inject fuel on the exhaust stroke the downstream exhaust simply isn't hot enough to burn that fuel. It will last a few minutes or less before that regen cycle has enough heat to burn all the extra fuel and soot. Both of my 6.4s did it, it looks horrible but you can thank the EPA.

I did a bunch of reading up on the 6.4 on the FTE web site. Lots of folks are doing the dpf delete with a chip to tell the 'puter to ignore the delete. From what I read, this is a sound fix, but voids the warrantee and some states frown on it (aka, illegal), kinda a catch 22. Sounds like your truck is doing what its supposed to do and what the EPA says it has to do. Without being hooked up to your rig, your truck is running cooler so when it goes into regen mode it has to dump extra fuel to make up for a cooler running engine for the dpf to burn the microcarbons.

Would that be white smoke?

Did I understand you correctly? The regen cycle is 20 - 30 minutes long? I hope it's not blowing white smoke the entire time!

I wanted a diesel for it's undisputable towing power and fuel mileage, but the thought of the repair cost without any warranty caused too much puckering.

I think he said 20-30 miles.......but that is still an excessively long time for a regen cycle....perhaps the ecu is prompting a regen cycle before the exhaust is hot enough......that would cause raw diesel to pass through unburnt?.....

My 6.7 regens are complete in no more than 12 miles as long as speed stays over 40mph ...hmm
Let us know what the dealer says....

Iíve often thought that my truck wasnít doing the regens the way it should. My tailpipes are black while most 6.4ís remain clean. Since I use my truck primarily for towing, I think because of the turbo pressures it was in passive regen more than most. Once it does go into an active regeneration of the DPF the cycle does last for about 20 miles, sometimes longer. When I first bought the truck the regens were more often and of a shorter duration.

Dave, both times the white smoke only lasted for about 5 to 10 seconds but it was a lot of smoke and very unnerving. This occurred at speeds below 30 MPH when I wasnít towing the Silverback. Now that Iíve owned a diesel I know I could never go back to a gasser for towing.

When I get my truck back from the dealership I'll let everyone know what they told me.

The likely reason your tailpipes are full of soot is because your DPF is cracked. If your truck is still under warranty have it fixed before it expires, it's over $3000. Otherwise drive it like normal.

I just returned from the Ford dealer and they assured me that the white smoke during DPF cleaning in humid/wet conditions is a normal phenomenon. They ran diagnostics on it and said everything is normal.

Since Iím not a diesel mechanic I didnít argue the point. I now have it documented that I complained about the smoking condition when the truck had just 30k miles on it. Tonight I will email Ford asking for confirmation that this condition is normal. With documentation I feel Iíve covered my ***** if this turns out to be a major problem once the warranty expires.

You may want to throw in the black tailpipe thing when you contact them again also. As Chewie said, that is indicative of a cracked DPF. I'd have them take a closer look. I think my 6.4L only puffed some smoke once, when it started a regen fairly early into my drive. Otherwise I never had any issues with mine.
