March 23, 2007  As bizarre as this may look, flames from a tail-pipe are not unheard of by any means. Ask anyone that has improperly set the floats in a carburetor or watched a stock car race at night. But this is a diesel and these kinds of things don't happen right? What you are looking at is a 2008 model truck equipped with a diesel engine that has an exhaust aftertreatment system and the result of an obvious malfunction. All diesel engines built and certified for highway and off road use after January 1, 2007 are required to have an exhaust aftertreatment system to meet the requirements of tightening Federal emmissions standards. Apparently we are learning new things about these systems as we put them to the test on the streets. The related video clip shows one such lesson in action, however the DTS does not know the origin of the video therefore we do not know where, or when it was shot and what the root cause of this thermal event was.

The aftertreatment system uses a Diesel Particulate Filer, or DPF, which is designed to collect and incinerate diesel particulate matter that is produced by the combustion process in diesel engines. This process is known as “regeneration” and it is automatically performed under certain operating conditions to clean the DPF and reduce system backpressure caused by the collected diesel particulates. To burn the particilate matter, the exhaust temperature needs to be elevated to around 1100ºF. The 6.4L Power Stroke® engine achieves and regulates this heat by injecting small amounts of fuel during the exhaust stroke as it monitors the exhaust temperatures though the use of three temperature sensors located in the exhaust system. On a couple of rare occasions, a fuel injector or the turbo has failed, combined with the normal regeneration process and produced a flame. These types of failures allow unmetered fuel or uncontained engine oil to mix with the exhaust gasses and ignite if the exhaust temperature raises high enough.

Details on the safety recall 07S49 are limited but the recall states that the PCM recalibration is “to limit these temperatures in the event of this rare combination of events...” What you have to understand is that manufacturers do not reveal things like calibration information and just how the new calibration will limit the exhaust temperatures or what was changed. We can speculate that a limit was never set, the tolerances were not tight enough or a limit was not thought to be necessary. After all, oil and fuel is not supposed to be getting into the exhaust and perhaps this kind of “thermal event” did not occur during the extensive testing period. We may never know but we are pleased to see that this concern has been identified and addressed early on. You never can tell what will unexpectedly turn up as new technologies progress.

Recall 07S49 was released on March 23, 2007 which requires the affected vehicles to have their Powertrain Control Modules recalibrated. If you own a 2008 F-250/350/450/550 vehicle equipped with a 6.4L diesel engine that was built at the Kentucky Truck Plant before March 9, 2007 you will receive a recall notice to have this recall performed. You may contact your local Ford dealer to see if your vehicle is affected or you can also visit http://www.ford.com/en/vehicles/owners/recalls/default.htm to enter your truck's Vehicle Identification Number (VIN) to see if it has been recalled.

Pretty wild video huh! but it is not a good thing for ford/navi. ford really needs to drop navi and go with something besides navi. be best if they would just build there own engines.

all the info you need on the 6.4L mine does not do this and does not sound near as horrible as that one does. mine runs smooth and is a nice and quiet pickup. i couldent be more happy with it.  

that is the only video i could find that had the flames shooting out of the exhaust.

so now what do you guys think of the 08 super duty. i think that the one i got is a awesome one. but by the looks of it i got lucky that it dosent do what that 6.4L does. that is the worst sounding diesel engine i have ever heard.  

what do you think that sounds like. to me it sounds like something is hitting something. whatever it is it is definetly not good.  

the truck in that vid if its the same one I saw a few weeks ago has a bad injector or something like that. That noise is the extra fuel it the cylinders or the injector its self making that noise. Either way that truck has issues!  

Wow that was one long post.  You must either work for ford or you are one passionate ford guy.  Good for you.  Even though I am just as passionate dodge man.  I respect that.  That being said, on left lane news it was said that the recall happened due in part to 3 small fires set by superdutys flamethowers.  In addition I believe the "fix" was to basically defuel the engine to alow egts to drop.  I am not going to bash ford but one of the reasons I went with dodge was my dad bought a ford one ton with the 460 in 1986 that had a bad ignition.  Turns out it was I think the eec4 and every single one had a crack which over time would allow it to short out.  Ford knew this but continued to put them in anyway.  Ford also thought it would be ok to route the fuel line in close proximity to the exuast manifold so when hot the fuel would flash to vapor and cause the engine to die.  Now my dad still has the truck, it only has about 70000 miles on it but those were some things I never forgot.  I am sure Dodge and GM have had similar brain farts in the past as well. I guess my point is it really dosen't matter what brand of truck you choose.  We all have the ability to develop ways to forget the past and rationlize our choice of truck.  Dodge, Ford, GM, and even imports all have strengths and weaknesses.  There is no perfect truck.  

What do you mean combining those 3 to get the perfect truck??? I already have it!! Sure i got a few more things to do to make it more perfect but it doesn't get much better than the OBS Fords!  

no i dont work for ford... i am a passionate ford guy though.    there would be a perfect truck if you combined the 3 together... be awesome if there was a pickup made that had the reliable cummins engine and the aweseom alisson tranny and the sweet bodystyle of the fords. also would be nice to have chevys interior, dodges offroad ability, and fords awesome sounding engine but that sound in the cummins engine.  

i know it wont happen but hey a guy can dream cant he?  

Go to Youtube and put" 6.4 Ford diesel flame thrower option" in the search box and you'll see some flame action!  

yes yes you will
