i have a 2008 job3, f350, 6.4, psd with about 2600 miles on it. up till now, the tailpipes have always been clean. today i noticed they were full of black soot all over the inside.

i took the truck to the tech at the dealership. the tech told me as long as no check the engine lights were on, that it was o.k. i told him i heard that it may be a dpf problem and he said it wasn't that uncommon for soot to be in the tailpipes.

i have not noticed any black smoke or performance problems with the engine.
anybody else have any black soot in their tailpipes?? is it normal??

thanks for any feedback,

From what i have read there should be NO soot at all on your tail pipe. If there is ANY - this is a definite crack in the DPF. some of these techs dont know crap - some are great. There is also a TSB on this problem. Im sure someone more experienced in the 6.4 area could give you the link for it. It states that there should be no black soot on the tailpipe - if there is service is needed (mostly for a cracked DPF. Goodluck!

 

Your DPF is cracked and it is NOT normal. Everything ford says about the 6.4 says the tailpipe should never have any soot at all in it. Eventually your truck will go into a constant regen, and your mileage and power will go way down. Sounds like a typical tech doesn't have experience, and just does things by what the computer says is wrong.

I have had soot in the tail pipe of my F350, 6.4 since shortly after it was new. I now have 7K miles and still the same. The service department doesn't seem to be alarmed at all when I bring this up. The truck runs great, no problems or error codes. It does go through a regen perodically. I would sure like for someone to direct me to any service TSB's that address this. I would also like anyone to direct me to any Ford statements that says this is abnormal or a problem. If I do have a problem, I sure would like to get it addressed. Thanks.... gene

 

yea, i fugured if the dpf was working correctly, the tailpipe SHOULD be clear of any soot as the dpf SHOULD be trapping it all.................

in -3- weeks i'm gonna be driving from northern arizona to pensecola, fl and back. i would like to get ford to do something before the trip so i don't get screwed with a major problem 1500 miles from home............!!!!

if anybody knows of any ford documentation/tsb's regarding soot in the tailpipes and cracked dpf's please post em.........i'm gonna print all of this out and make copies for the "stealership" and get them to do something before i leave. thanks for any help..............

I'm a "stealership" tech, and I don't believe I need to, after that eloquent statement!

hey vloney, here is the situation. i took out a loan from ford promising to pay them back for a truck they promised to warranty for 3 yrs. i've kept my promise and made my payments and will continue to do so.

i took my truck to the dealership and told them that there was soot in my tailpipe. the tech told me it was not a problem if there was not a check engine light on and have a nice day. IF this soot in my tailpipe is from a cracked dpf and the dealership tech is PURPOSELY not replacing my defective dpf, this tech, who is a representative of ford, is STEALING from me........plain and simple. i hope, this isn't the case.

so, since you are a master tech, what's up?? should the tech/ford even look at this?? does soot in the tailpipe mean i have a cracked dfp???

As a test engineer for a major heavy truck OEM and having tested dpfs on our trucks for the past 3 years, I can tell you without any doubt that you have a cracked dpf. There is a reason why it cracked and that must be accurately diagnosed. The most common reason for cracked dpfs is soot overload. This condition can be caused by many different scenarios. Having read about the many forum members that have experienced this, I'd be willing to bet Ford knows of a problem or condition that causes this and has some documentation explaining it in detail. If you aren't getting satisfaction from your dealer, may I suggest you try another one. Like someone said, not all techs are as experienced as they need to be. Don't let them BS you when you've been given very accurate information here.

 

thanks very much for the information rob,

i'm gonna print everything written in these forums, take it back to the dealership, and demand that they service my truck. at $4.79 a gallon, i shouldn't have to drive a 100 mile round trip to another city for an honest service dept.................

The "stealership" is an easy explanation. It's not meant to be degrading to any of the "qualified" diesel techs that are out there. It is aimed mostly at the lovely service advisers who recommend excessive repairs that are not required. Like the $1200 estimate I received when I took a truck in with 200K on the odometer. After asking if that would solve the issue, and a barrage of other questions I discovered the tech had not even looked at the vehicle yet, the service adviser simply quoted all the recommended things she could find based on my odometer reading.

There's also the stories from the unqualified diesel techs like the one that told a member here that his 2008 6.4 did not have a DPF. They only installed DPF's on the gas motors.

If every time we went to the Ford house we were able to deal with knowledgeable, qualified techs, you wouldn't see these types of comments. It's in no way meant to be disrespectful to you or any other qualified tech out there. If you would be kind enough to provide a TSB number or any other relevant information that might lead a tech to look for the correct information it would be greatly appreciated. It would also save the headache of someone having to argue with a supposed diesel tech that the DPF does indeed get installed on the 6.4 and not the gas motors.

I hope you have a change of heart and realize these comments are not directed at you.

 

I am messing up when responding with a reply to a posting. Would someone tell me how to highlight the quote in a previous post so that I can respond to that quote only. Hope this makes sence... -g

 

Delete the rest of the quote so only what you are replying to remains.

 

My gripe is the "stealership" mentality. Is there questionable techs in the field.....sure, both dealerships, and independent garages. Equally, there is PITA customers. They are not difficult to recognize, "I've spent a lot of money, and I think you need to do anything I want you to!". They have this thought from the first second they walk in the door. Ford does have procedures that must be followed to have a warrantable repair. If we jumped on everything that "My girlfriends uncle said that this is wrong, and you have to fix it no questions asked" Ford would go broke. Have you got a dpf gone bad..... Probably. What caused it? Are you wanting the dealership to just put a dpf on and do nothing else? If you want a parts changer, take it to Joe's dirt floor garage. Am I bitter about the STEALERSHIP comment........YOU BETCHA! I spend 40 thousand on tools to make me do my job more efficiently, go out of my way to get training, spend hours away from my family to further my understanding of these new vehicles, AND I STILL HAVE TO DEAL WITH PEOPLE THAT THINK THEY OWN ME! Then they ask for a favor? Now, just to show you that I have dedicated my life to helping everyone that I can, Tell your dealer to look at 07-8-9

 

Much thanks, now I get it. I never noticed the quote box before that one must click on. -g
