08 6.4 F250 blowing white smoke??

I have a 08 f250 that I have not had long, it is completly stock. It has started blowing lots of white smoke while accelerating from a stop or going down the road, it will stop for a little bit and then do it again, and it dosent say cleaning exhaust filter. I was wondering if it could be a clogged dpf? If anyone has had the same problems or any ideas as what it could be please let me know? Thanks!

Did you notice if your fuel mileage has gone down as well? When my gf's 08 cleans the dpf the mileage drops off to about 8-10 mpg and blows white smoke like crazy. Her truck also doesnt say when its in cleaning mode. If it is blowing alot of smoke all the time you may want to have it checked out.

are you loosing coolant? could be egr coolers leaking coolant into the exhaust stream and burning it off in the dpf and cat. if so, you will have to replace the dpf and cat due to contamination along with the leaking coolers. also, the clamps are one time use so if you replace coolers, get new clamps

I had a similar problem. EGR became stuck open which caused lots of white smoke. However, in that instance, the truck sputtered and had very little power.

I noticed you said it is not during regen.

Is it happening in humid conditions, or rain, after running at a steady speed for a while?

Is it accompanied by the engine stumbling?

More than likely it is the Egr sticking. Mine does it also

seen this kinda thing a few times, could just be condisation in the intercooler, there is an ssm about that.
pull the lowere cac tube and look for water or oil.
i had one the other day with a leaking injector and it overfilled the crankcase so bad that it was sucking a oil/fuel mixture up through the breather tube and FILLED the intercooler. best way to eliminate that as a possible issue is to shortstick the dipstick and check the oil level.

Have you had the recall flash done on the ecm; it correct the issue of the dpf cleaning happening more often then needed?
