Lately I have noticed a lot of white exhaust smoke coming out the tailpipe.Normally when I see warning on dash for cleaning exhaust there is only a little white smoke now it continues for a few minutes...I am like a smog machine going down the road.A Ford dealer here in Fort Mill,SC could not find anything today....thoughts...suggestions...we'll see if the smoke continues today..

What does is smell like? If it has acrid odor, like burning trash, then its probably still trying to burn of a plugged DPF and hasn't been able to finish a cycle. You may need to to give it a good hard highway drive in this case.If it has any semblance of a sweet smell, you probably have a ruptured EGR cooler. Less common than on the 6.0's but still happens on the 6.4L.

Lots of reports of 2011+ GM Duramax trucks doing this as well. It's unburnt diesel fuel in the DPF that builds up during the regen process. My truck does it occasionally if I am in the middle of a regen and stuck in light traffic for a while, then get on it and its a huge cloud of white smoke.

I've noticed this with the 6.4's on the road too and some smoke really bad. I would keep a close eye on your radiator and oil level making sure you're not loosing radiator fluid or making oil.

I had an 09 with the 6.4... that was the only issue I had... It would be like the old time bug machine rolling down the road...Your DPF filter is either clogging , or clogged.. there is a company up in CT that specializes in BAKING those to be new , as apposed to buying new with a cost od $3000.00.. or close.

Probably an active regen vs passive. Mine blew tons of white smoke during regen when I was not driving it hard enough. Scared the bejeezus out me the first time it happened.

What about that issue they had with moisture in the exhaust or something similar? Its been over 5 years since I had mine but it would do that after excessive idling and especially if I floored it after some light cruising.

Mine hit a point where it was going into regen about every 50 miles for 20 miles at a time. Ford also told me it was because my longest drive when not towing ( daily driver) was 10 miles at a time.. It would not get a good cook off to clean , so it clogged...

Ford thought I needed to drive it longer distance to burn off particulates
