Ford Diesel Truck Recall

[Notanlines]

John, we weren’t aware you used such language.
On another note, same subject:
“ The transmission control valve can wear out over time, which can cause the valve to lose pressure.
This can lead to harsh shifting, and in rare cases, the rear wheels can lock up while driving.
This increases the risk of a crash.

The recall affects 2020–2022 models, including Chevy and GMC's full-size trucks and SUVs, but a software update fixes the transmission-valve issue.”
Same thing, a software update makes everything just hunky dorry!

While Ram is not without their own issues. Much of the repairs are easier due to the inline design of the engine.
The Ford 6.7 Power stroke seems to be the most complicated diesel of the big three.

A "software update" to protect the C4 pump from damage caused by "aged biodiesel deposits" ????

Maybe it's my "inability to understand the power of modern software", but .....

it has something to do with reducing temps in the CP4 to prevent deposits which makes sense I guess. what doesn't make sense is that we didn't just start losing the odd cp4 in 2019 or what ever year and up the recal is for, and we didn't just start using biodiesel blends, so why isn't the recall for all 2011 and up?

I’ve been looking at new trucks so this peaked my interest…I saw where chevy and ram cp4 was/is a gear driven pump off the front of the engine and the Ford 6.7 tucks the pump up towards the engine valley and because of that it’s an electric driven pump motor…. i guess it has a return line back to the tank? maybe they can use software to speed up the pump and flush the deposits back into your tank to be caught by the fuel filter? …just a guess

where did you ever get the idea that you have an electrical motor driving the cp4 in a ford 6.7? it is driven off the camshaft gearing, it just sits behind the gear instead of Infront of it.

Well a fine condescending good morning to you as well! about the 1min30 mark and after

Just going by what i saw on the interwebs …I havent worked on Fords but have worked on diesel engines…currently own two Cummins 5.9 and a two 6.7 and have a Case diesel backhoe between my son and i and rebuilt a Volvo marine diesel for my sons old boat … so i do get around diesel engines….just not familiar with Ford

wasnt ment to be condescending in any way, I was more in shock that some one is spreading that. an electric motor sandwiched between the cp4 and the turbo would probably die real fast.

ok so what that is talking about is the lift pumps. GM and Dodge have a built in lift pump where ford uses a separate electric lift pump to supply the low pressure diesel to the cp4. there is enough space to do the same as dodge and gm did but ford has been using the electric lift pump since the dawn of time so they just went with that option.

thanks for the explanation ….sorry for my snarky response earlier …misunderstanding …is that a variable rate low pressure pump? I was wondering if the software could change the flow rate of the pump? if it has a return line back to the tank it could flush out the deposits possibly??

i’ve read where in forscan you “may” be able to “possibly”change the rate of the variable oil pump in the Ford 7.3 godzilla that has low oil pressure at idle from the factory as another example of software changes and Ford pumps…that is one of the many theory’s about some of the 7.3 lifter failures

I don’t own any Ford pickups so i’m only going by what i hear ..i do have a 2023 (or is it a 24??) Ford transit but that has a 3.5 v6

the lift pump is just a simple on and off pump that will deliver more volume at a specified pressure than the CP4 can use, so it is just a single pressure/volume pump. for example when I go to start my diesel up in the morning when I turn the key on to let the glow plugs do there magic you can hear the low pressure pump start up and build presure in the system then shut off, I Imagin it runs constantly once the truck is started but I have never crawled under to verify that.

Has any one invested in the products from S&S Diesel? I.E. the disaster prevention kit and or the DCR pump to replace the CP4? I want to get the disaster prevention kit. Cheap insurance considering the alternative ( total fuel system replacement )

I guess the powers to be at Fraud just can't face up to the fact that the CP4 pumps are crap, & are to cheap to replace them. It didn't matter what brand they were on they failed.

Yes! S&S is intimately familiar with CP4 pumps at a much deeper level than any other competitor.

I have personally installed their disaster kit and have had others buy it based on my recommendation and knowledge of an owner of S&S.

KYD on youtube also did the DCR conversion but thats quite involved vs the disaster kit.

A disaster kit, good fuel from high turn over stations, and replacing fuel filters will all help longevity.

DPK does nothing for system longevity.

The DCR conversion, from Mark's perspective, is no more complicated than the DPK install. Either only takes one swipe of the credit card. They still sold the truck because they didn't trust it over...batteries and what, DEF heater/pump replacement?

The CP3 is not really more durable than the CP4. It's just that it fails/wears more gracefully. At some point it wears enough that it can't keep up with high return worn injectors and you still get a low rail pressure code.

Your partly correct. The disaster kit essentially cleans the fuel twice since return fuel is filtered. But fully agree its not a 100% fix but will save lots of cash when it fails.
For a DIY the disaster kit is far easier than a full DCR swap. But if your paying a shop then yes its just a credit card swipe.
CP3 is irrelevant because it doesnt fit in the V of the ford powerstroke hence the dcr pump.
Finally KYD loved their truck but didnt want to delete the truck. Replacement of after-treatment parts gets expensive fast

its supposed to be good, but do we need to run out and grab a new pump for no reason at 2000.00 bucks. I would put a disaster prevention kit on mine first if I lived in the US, then if it goes do the dcr as a replacement. the dcr is new so I would want more miles to see how they do. the cp4 issue is caused by bad lubricating standards in the diesel fuel. the US has the lowest standards so they have a bout a 7% failure rate, the EU has the highest standards on both lubrication and cetane which is why they get a bit better fuel milage and only have a 1% failure rate. in Canada we have the US's bad cetane rates but we do use the European lubrication rates so we find we only have a 1% failure rate also, but that could change for someone who lives close to the boarder and is in the US getting fuel all the time.

My plan exaxtly

 

[JRTJH]

I use a "Diesel Kleen" additive at every other refueling. I usually refuel at 1/2 tank, so I've always got "extra lubricity" in the fuel. So far, it seems to have worked with the exception of the #2 fuel injector having an electrical failure which is not associated with the pump reliability. I think adding lubricity to the US diesel fuel can't hurt the pump and may prevent catastrophic failure. So far, it's worked for me, but I've only got 88K miles on the truck.

 

[flybouy]

I use the Deisel Kleen as well. Seems to work well for me with ~190k on the odometer.

I watched a few videos by bob the oil guy who did some tests on the different additives with actual scar pad wear and cetane tests with the different additives added to the diesel and a baseline of the diesel. the best I found that I can get was archoil AR6500, XPD did slightly better but I can't get that. I am going to start using this one as it was miles above the others in the wear test and did what it claimed for the cetane. the power service was a all around good one, but I decided the lubrication part was a little more important than 0.7 extra cetane haha if I can find the good video I'll post it here for ya.

Yep, It may be a slightly better product, but trying to find it when on the road (or packing an extra 3 gallons of flammable liquid in the truck or trailer vs a "hunt for additives" in nowhere Utah brings me back to a "grounded, every WalMart sells DieselKleen... To me, I'm reluctant to "blend multiple additives" and try to always use the same product consistently, so availability, especially when on trips is an important factor in which additive I use. YMMV

fair enough. I order it from amazon, as I can't get it locally here either, but its 1 day shipping for me.
