I took the rig in a couple of weeks ago to investigate the same smoking issue (but mine happens only during regen.) They said they ran some KOEO test and it was operating perfectly normal. I also got that OASIS blurb saying 'Engineering is investigating'. The blurb was dated back in August, so I asked when to expect some feedback. There's no definite answer other than to check back with them every once in a while.. I was saying to myself, what if I got a DPF delete in the meantime....

 

I'm going to see what trade in is on my "normal " truck. Oasis is starting to look like a mirage.

 

Good luck on the trade-in. With the new 6.2 and 6.7 motors, many dealers are not offering much for the 6.4's, or older diesels (at least in my area). I ran into this problem when I traded in my 08 with 43,000 miles that was having regen, and smoke issues. I tried several different dealers and none of them came within KBB values for a trade because they are using Intelliprice, or similar companies to determine the BB value. Unfortunately there is a huge difference in the process used between KBB and these other companies, and some dealers are using the difference as a strong argument toward a lower trade-in.

Just wanted to warn you. Any good luck with the fix or getting a new truck.

My 2008 6.4 white smoke was broken EGR valve. Good reputable Ford dealer diesel specialist had to replace ERG, Radiator, and cooler. Under warranty.

 

Here's the latest on my situation. Truck still smokes although after the last visit to the dealer it did manage to go 814 miles before erupting. It now is back to smoking frequently and randomly. Still the only thing that has "officially" been done on my truck was a Ford authorized freebie oil change. I have been told that it is NOT the EGR, Aftercooler, Turbo, DPF, and that there are no codes. I have been handed the CAS TSB no less than four times even though it doesn't describe the same issue as my truck is having. I have an open claim with Ford Customer Care, Ford is offering the ESP to me at no cost "for peace of mind", the dealer has offered me 20k on trade which is not even close to where I feel they need to be, and no one wants to actually touch the truck anymore. I think they all smell lemon and don't want to throw parts at it, making it easier for me to get out of the truck. I'd actually prefer that my truck just simply gets fixed and I'll take the ESP for my troubles but I don't think fixing is ever going to happen. Anyone got any ideas?

 

I still think you have leaking injectors. I assume they checked you fuel pressures?

 

Sound like it is stuck in a regen cycle.....

 

Thoughts:
After getting this back it worked well for 814 miles and then smoked. Sounds like the dealer flashed the Computer and now something is causing a fault ( sensor) or triggering the condition.

When I removed the Cat and DPF I ran the truck for a few minutes to warm it up as per the directions from the tuner and I created some real smoke white with Blue tint.

I am thinking the crappy smell is coming from the Cat had this happen to a car or two I had owned. Why the smoke if Oil levels are OK, Water is OK, it lends to a fueling issue which would complement the hi fuel consumption rate.

Rough Idle is either compression or fuel, if it runs ok for 814 miles I would think this leads to Fuel issue. I think something is causing the computer to think it is in a regen cycle and fueling during the exhaust stroke. Question is what? Clogged Cat??? or DPF???? this would cause a high back pressure situation and trigger a burn to attempt to clean.

No Oil being used, I would rule out a oil leak in the turbo oil seal or you would have detected that in the weekly oil check.

Silly question the AIr filter is clean/clear yes?

 

Did you program for DPF delete? If not your truck will stay in regen!

 

I agree it with the "overfueling" idea, especially since my only fluid change is the increased fuel consumption. Air filter is clean. I have noticed that since the last time I got the truck back, about 50 miles after a "smoke event" the truck will cycle through cleaning exhaust filter anywhere from 1-4 times in rapid succession. When I get rough idle, it doesn't last for long but is accompanied by a lot of injector noise. But I don't get why no codes, and no change in performance during smoking.

 

Same stuff going on here....I had my 2008 to the dealer for to much smoke, they did the update that I had to pay for..51,000 miles. I drove 60 miles to another job and the drive to clean light did not go off. There was another dealer in the area, they said the high oil level would trigger it..They changed the oil, same BS
The truck has been using fuel like crazy 10 mpg and constantly goes from cleaning filter to drive to clean..I shut the truck of the screens says complete, then when I start it says drive to clean. Out of con troll . They mentioned fuel is junk, its cold out and to use fuel booster I use it, no difference.

Back to Ford tomorrow...Crazy

 

Something is telling the Computer to go into a regen.

When I did my delete I installed the pipe and sensors and reconnected all. No Cat no DPF, No updated tune yet and started the truck, all was fine for a few minutes and then white/blue smoke from the tail pipe. from what I understand there is a pressure differential between the first and last sensor in the stock exhaust system and if that differential is not within limits ( hi and Low) the computer will issue a regen command which = smoke.

Since updating my exhaust and adding the tuner I have had only a couple of minor issues that caused smoke, code thrown for 1 injector , I cant remember the number but recycling the key made it go away. This happens only when cold and only at Idle. The Smoke will not go away with RPM. I am told that this is due to loose wiring or connector either at the Injector or in the harness.

I bet in your case you have "noise" on or in the control loop that kicks you system into thinking it needs to regen. This could be a ground issue, loose wiring, chafed wires, etc. Could even be a bad computer. You did say after the Ford dealer had for a While that it did run OK for 800+ miles.

Question, is this smoke issue temp dependent? I.E only happens when air temp is below XX or above XX?
Question 2, Performance doesn't change when smoking?

 

Something to think about if this can't be resolved by Ford is look at a Delete Kit. Talk to one of the Hot rod diesel shops shops Rudy's Diesel or the like to see if they can give you some insight. the guys that race these things might have some more info as to how the machine really works.

 

Just got the truck back from the dealer, Found no codes and nothing wrong...But did anorher flash that they said was very recent.. had one done two weeks ago....see what happens...just seems crazy... haven't had a gas truck in years, hope they figure this stuff out before I buy another..

 

3 local dealers and no one will even look @ the truck. One service writer even told me "they're junk " and the techs don't want to work on them because Ford won't pay for their time spent. It's too bad, I actually like the truck otherwise but I guess it's time to pursue the lemon law. One dealer even tried to send me somewhere else because "they don't have a lift for that size truck". Which is funny because I used to work there and I know that is not true. Who would believe that crap?
