Diesel Dawgs…Please Help Me Troubleshoot

Sludgemonkey44 said:
And to all of you who say hey just delete it. Yeah like I said in my original post, it’s an opinion that I have considered. I’ve also considered the fact that by deleting, I’m lowering the resale value, shrinking the potential future buyer pool, and therefore making it more difficult to sell for a decent price when I do decide to finally part ways with it. Not to mention I don’t love the noise and stink associated with the loss of the DPF. I definitely have a love hate relationship with the entire system.

Judging by this post, it seems you haven’t been around a truly "clean" diesel engine—by clean, I mean one without all the diapers components. Honestly, there’s nothing stinker than DEF, especially when it’s being cooked.

I think there’s a big misconception about these stock engines. Just because they seem “clean” doesn’t mean they’re healthy—you just can’t see what’s happening inside. Open that engine up and see all the buildup it’s been collecting and swallowing in over the years. Why would anyone want to buy that? Personally, I’d choose a genuinely clean (deleted) diesel engine over one that’s been eating its own farts for five years.

The whole point of a diesel engine is its ability to be driven for a million miles, but unfortunately, the way they’re being ran today makes that impossible. Gasoline engines, in their stock form, are certainly much cleaner and potentially outlast modern diesel engines.

If you don’t need it to reach a million miles, then sure, run it until it gives out and then replace it with a new one. They sell more.
 
Seems like a $275 retail priced part for the DEF injector. Might be an easy fix.

If you can't get codes you are just throwing parts at it.

Is that something I can read through my Banks Data Monster (or whatever that pod deal is called)? I remember being able to see and clear a code a few years back through it.

And speaking of codes, will some codes show up without a warning light coming on? Nothing has shown on the instrument panel indicating any codes being thrown.

Yes for the DTCs, the PIDs will be hit or miss. I have one as well and some PIDs that I would think are essential, Banks does not.

It is weird on whether it shows a CEL or not. The part for the NOX11/12 I am not sure but along with that, look at your EGTs. If the EGTs are normal and not high, but the NOX12 is reading high, then you are almost assuredly overdosing either being commanded or because of the nozzle itself.
 
I just ran a scan on my truck through my Banks deal. 0 codes shown. Odd. I know I’ve made this trip with this trailer before on less than tank of DEF. This time it took a tank and a half.

I’ve been around plenty of pre emissions diesels and plenty of newer ones that have had them removed. I’m no spring chicken. Not sure how belching coal soot is considered clean in your experience but different strokes I guess.
Definitely not clean or odor free in mine.

Did you notice or keep track of your EGTs? Was it super windy or windy and colder than normal? I used to live in Minot and the two things I hated were wind and the damn cold. Even as an MT guy, the cold got to me.

It was hot as balls out there (well considering the time of year). 60’s and 70’s for highs, 40’s for lows when towing. EGT’s were 600-900 out the tailpipe. Wind was normal for there.
Normally without the trailer they are 250-500. Occasionally will hit the 700’s when highway driving. Definitely was in passive regen stage on way out and back. Know it would use more than not towing, but it used almost twice the amount this time for same distance and same trailer

DEF does not freeze at temperatures higher than about 12F. Wind chill has nothing to do with actual temperature; wind chill is a "human" measurement and does not make the ambient air any colder. It's likely that crystallization is just a prolonged result and eventually will clog the system. It really sounds like the injector is just stuck open. Ironically, water is all that is necessary to un-crystallize DEF. But it is a hassle to do the maintenance on the injector. Personally, I would try cleaning it if the truck wasn't under an extended warranty. Past that, I would likely replace it.

DEF was fresh from a truck stop pump on the way out, and i honestly didn’t look at the expiration on the box I bought I threw at it on the way home. It sucked down half a tank in 1200 miles. I normally get well over 5000 on a tank even with a substantial amount of towing included. I’m not thinking it was the DEF. It was almost certainly something malfunctioning in my DEF system.

The only 2 times I’ve had a problem with the DEF system (aside from the heater in the sending unit) was after I used DEF from a pump. I know it’s convenient, but never again.
 
Deleting won’t affect resale. Deleting will get rid of potential failure modes that leave trucks on the side of the road.

Thanks for the reply Trek. Your suggestion is the direction I’m leaning. Visually the injector looks fine from the outside. I’m out of warranty, so it’s all on me at this point, so I’m thinking I’ll pull it and inspect and clean. If necessary I can jump on the motorcycle and run to the dealership to get the one they have in stock, and pop it in if the other one seems bad. Also, I saw (on the internet of course) that the unplugged injector should read between 11 and 13 ohms across the pins, so I’ll probably try unplugging and testing it as well. If cleaning/replacement doesn’t work, I’ll reconsider my options at that point.

Tell that to a bank. Or a Ford dealership for that matter. Both parties around here won’t touch them.
 
A dealer is going to lowball you regardless of what you bring to them. When I sold my deleted 2012 6.7 neither of us discussed the condition of the emissions. There is a large market of individuals who put a premium on a deleted diesel. Since deleting is a concern I’d try cleaning the injector first. Then try swapping the injector if you know someone else who has a 6.7. Once you open the bag on the new injector the dealer will not refund the purchase.

Totally on par with this and have never understood the notion of having to wait til "warranty runs out," when all the damage has been done and you are... well out of warranty. . . :rolleyes:

It's clean, and silent.

We may be in the minority, but some of us really appreciate these attributes.
 
FYI, depending on when you bought it and your current mileage, it would be under warranty. DPF injectors are covered under Ford’s underlying factory diesel-engine warranty covers them for 5 years/100,000 miles

Exactly this! I use Plat Def now for the crystallization issues. DEF is DEF for sure as far as the catalyzation process goes but the additive goes, so far, when I have removed the injector and looked, things are nice and clean... well clean as pertains to exhaust and the DEF. Beyond that, I keep a bottle of Hot Shots DEF treatment in my truck just in case I run into anyone out in the boonies suffering from this shite!

That said, it might not be a bad idea to use


in regular DEF as that is essentially what is in DEF Platinum. I don't have any first hand experience with their claim that it restores and corrects DEF clogging but at 1 oz per 2.5 gallons, it couldn't hurt to try. My neighbor uses this instead of Def Plat as he buys the Wally brand DEF and with this is cheaper.

I have pretty much been using Tractor Supply/ Wally World DEF since the problems with pump DEF. That was the old truck where I had issues. The new one drinks it like a frat bro with Natty Lite. 9k and no issues so far on 3 tanks of the el cheap….yet.

For true on my 24 too. I'll take the truck being a DEF drunk with the reduced EGR use of these 23+ over the older ones though. I've pulled my intake off twice now to look and see how coked up the valve is at the EGR/CA Cold Pipe and the upper intake path as well as clean if necessary. So far, it hasn't ever been really bad. I'd describe it as more of a dusting rather than a coating.

Military or you lost a bet...

We had a church raffle. 1st prize was a week in Minot. Second prize was 2 weeks in Minot.
