DPF

Last night I had a 2009 F-350 6.4 at just over 100,000 km with the typical signs of a DPF failure... Will not regenerate, blows lots of black smoke, black tail pipes... yada, yada, yada... So, I submitted a prior approval to get it declined. Turns out that in 2009, DPF coverage dropped to 5 years/80K. So, the vehicle is still under diesel engine and powertrain warranty, AND this poor guy bought the 7 year Diesel Care warranty. Nothing covers it. I kind of felt sorry for the guy.

 

Not ranting. Just a heads up to those of you that haven't dealt with too many DPF failures after 2008 model year. Cheers!! Posted Image

Did the debit queen tell you this, or did you find out on your own?? Posted Image I could've sworn I'd submittted some later than that, but they may have covered it due to it being damaged by oil contamination after HP turbo failure.

What a joke...and they wonder why people buy the aftermarket delete kits and programmers to remove the dpf function. All that would be cheaper then having to buy a replacement DPF from ford.

 

I know I have covered DPFs upwards of 95k before but never on a 09-10 MY

I am not sure that a DPF or even a CAT should be cleaned after being oil soaked or completely soaked with coolant. If the coolant doesn't poison them the oil dousing would greatly reduce the efficiency of them. Ever notice that Hot-Line responses to catastrophic engine or turbo failures is to inspect and if necessary replace the DOC and the DPF?

 

But I am talking about the stuff that reached soot loading limits or the ones that become plugged from excessive idling for example.

 

I JUST had an F350 in that suffered from a major lack of power and could not manually regen. I attempted a road test to get the truck hot, and I did. The DPF was glowing red and the dash insisted that I pulled the truck over safely and shut it down. It had no throttle response and would not restart (crank)

 

But that event opened up the DPF enough where a manual regen could be performed and it was, successfully. A long road test confirmed all was okay and the township was told to stop idling the truck and was introduced to the engine hour meter. Hopefully they will become good friends or else they will have some expensive repairs in their future.

I think FSX says an oil soaked DPF can be baked and cleaned. I'll find the document and post it.

Anyone remember my post and the photo about the Mexican Manual Regen?

I still laugh at the fact that it actually worked. This one was just plained coked from too much idle time though. I wouldn't want to try that on an oil soaked unit.

I just assumed it was covered. I ran the prior approval tool (without first checking for parts coverage). This was the response...

 

Alex, While we agree that a failed DPF will cause sooty build up on the exhaust tips, the DPF is out of base warranty coverage by distance on this vehicle. Please note that DPF coverage changed starting with the 2009 Model Year, and is: 5 years/80,000 KM (50,000 miles). In the future this information can be found by running the VIN in OASIS and selecting the Parts Coverage Tool using the DPF base part# (5H221).

There is a lot of parts that only have coverage to 5 years/80 000 km on the 6.7. I just did a retail def fluid pump on a 2011 with 82 000 kms. I hope they have some kind of esp that will cover parts like this. Does chevy and dodge have a similar warranty for emission parts?

I am still mystified as to the absence of cleaning services for DPF's on light duty trucks.

Had a customer inform me there is a Kenworth dealer in Edmonton that cleans heavy duty DPFs. They have successfully cleaned Dodge and GM DPFs, but have yet to try a Ford one yet. He is going to let me know if they do. He wants to get his cleaned, but his truck only has 64000 KM on it, so it may take a bit. Will post if I hear more.

Most (if not all) LD DPF's are enclosed units welded into assemblies and not intended for any external service. All MD/HD DPF's are canister style and very easily to remove and service. Did you see my pic of a cutaway 6.7 DPF assy? It has 5 cats in it, all welded into one assembly. Good luck cleaning that $ucker.

 

There's a guy on Ebay cutting open and cleaning 6.4 DPFs.

Bruce it makes you wonder why the manufacturers of light duty trucks chose to make them this way as opposed to how the heavier duty DPF's are. I suppose cost of manufacturing: making a serviceable canister might be more involved than a welded assembly. Also consumer tampering: it would be more convenient for the consumer to remove their DPF's with a canister style I would think.

If you check the WSM, a 6.4 DPF is to be removed and cleaned at 200 000 km (ok 192 to be exact), and replaced at 400 000km. It also states the the DPF can only be cleaned once. This is to remove small amounts of soot/ash that are not removed by normal re-gen and can accumulate over time. I doubt any of these things ever lasts to 200k, but that's what the blue oval says. No as more wet contamination, I have no idea if that can be cleaned or not. I have removed DPFs for cleaning, but make sure you order the pressure sensor, the EGRT, the hardware kit, and the other nipple that will strip/break off. For those of you boys in the GTA, Peterbilt in Miss. on Eglinton will do this. Also A&A Exhaust in Hamilton offers the service, and will often pick up and delver.

 

Edit: Also I beleive they use a "Thermal" cleaning"

Keith: I'm sure cost of mfr is what it's all about and they could care less if it's easy or hard to tamper with.

 

They "say" it can be cleaned once, but what's their procedure? Blow it out backwards blowing everything through the DOC? Must be. Posted Image

 

The cleaners cone in two general types- blowers and ovens. Blowers are done cold with either pulsating air through a nozzle or with an accumulator that stores air and "bangs" the air through. The oven method bakes the DPF over a long period of time (slow ramp up and down in temp) and then the blower is used.

 

FSX makes the most popular DPF cleaner endorsed by several HD engine mfr's. Here's a couple of videos worth watching:

There is a place in Windsor, Ontario that does it. DPF Cleaning Solutions is the name if I recall rightly.

 

We fixed his 08 450 a year and a half or so back in London here.

 

(Diesel particulate filter cleaning guy filled his truck with gasoline Posted Image )

 

492,000MI on an 08.

 

OH! And FWIW: Wouldn't a stage one pneumatic cleaning be a supersized Mexican Manual Regen? Posted Image
