many of our readers are aware, over the weekend a video of a
2008 Ford Super Duty shooting flames from its exhaust appeared
Doctors Diesel Technician Site and YouTube.
safety spokesman Dan Jarvis told PickupTruck.com today that, "The
video is definitely one of the three trucks we described last week
(see below, in the original story). It was sent to us by one of
our dealers in Canada, where two of the trucks in the recall were
located, and it illustrates why we took action so quickly. We wanted
to alleviate any potential safety concerns about this issue right
not 100% certain of the cause of the fire seen in the video,
Jarvis said the truck in the 75-second clip is probably the
Super Duty that was started in very cold temperatures (approximately
minus 20 to 30 F). Its engine wasn't given enough time to briefly
idle and lubricate the turbocharger in the freezing weather
before the truck's operator drove off, resulting in a blown
bearing seal in the turbo and a leak of combustible fluid (likely
oil) into the pickup's DPF.
also gave an update on one of the other trucks that had a leaking
fuel injector, which caused another instance of flaming exhaust.
After shutting off and restarting the motor the problem causing
the leak in the injector resolved itself without requiring any further
maintenance. It was likely caused by some sort of obstruction that
was removed upon the engine's restart.
about what this recall could mean to Ford's launch of the all
new 6.4-liter Powerstroke diesel and 2008 Super Duty, Jarvis
"This is a great engine. We know it's reliable. We've had
a few minor cases with individual engines and we're taking very
fast action to fix them, and we'll continue to be transparent
with any actions we take."
when asked about if Ford had initiated this recall because this
problem might be occurring in a sample population greater than the
three trucks originally referenced by Ford, Jarvis stated, "We
think these three trucks are very rare cases. We're not seeing this
in any other vehicles in the field."
you own a 2008 Ford Super Duty with a 6.4-liter Powerstroke diesel
engine and would like to see if your pickup is included in the recall,
you can enter your VIN at Ford's
recall information website or contact the Ford dealer where
you purchased your truck.

talked with Ford spokesman Dan Jarvis this morning to learn more
about the Super Duty recall and its accompanying software patch
to prevent fiery exhaust events from occurring. Here's how it will
work and what it could mean to drivers with a leaking engine component
that allows combustible fluids to enter the exhaust system and become
trapped in the diesel particulate filter.
software fix will recalibrate the engine's PCM (power control module)
so if it senses that temperatures have climbed too high in the DPF
it will begin a gradual reduction of fuel and air flow to the engine
to help bring the temperatures back down," says Jarvis.
should be noted that the software patch WILL NOT fix the root cause
of any oil or fuel leak in the motor caused by faulty hardware.
describing driver awareness and action during a 'powering down'
scenario, Jarvis said the following, "(The driver) will see
a message on their instrument cluster that they need to pull over
to the side of the road. Within five to ten seconds, the engine
will begin to lose forward power and the driver will need to pull
off and stop to wait until the DPF has cooled down. The vehicle
will not lose power steering or power braking during the power-down
and it won't stop all together. Drivers should have enough time,
if they are on the freeway or a bridge, to pull off to the side
and shut the engine off. After the DPF cools down the driver can
restart the vehicle, and then we recommend that they take the vehicle
to a dealer for service."
first announced yesterday, it was unclear if the problem occurred
only during DPF regeneration (see below, in original story) or at
any time while driving. Jarvis states, "the problem could occur
at any time, not just during regeneration, because the exhaust temperatures
in the DPF are hot enough that any fluids could ignite (during normal
driving). Hot weather or normal DPF operation will not trigger the
power down. Only if there are burning hydrocarbons in the DPF is
the temperature going to get hot enough to trigger the power down."
emphasized that in order for the phenomenon to happen, something
in the engine has to be leaking. At least one of the cases was caused
by, "a driver in Canada who might not have let the engine warm
up when it was about 20-degrees below zero, causing a crack in the
Ford Super Duty owners with Powerstroke engines can receive the
flash upgrade to their PCM at their Ford dealer. The operation takes
about 3 minutes to modify the engine logic. Letters from Ford will
be sent to owners, and dealers are calling to notify recent purchasers
of the recall.
moving immediately on this, and we're proactively notifying NHTSA
of the recall," says Jarvis, "because we think it's the
right thing to do."
