Any Problems Yet?
 

most of us know of some of the problems that they are having with the new ford and i was wondering if there were any common problems that have resurfaced yet on these new cummins. so lets have em :pc:

TTT anyone? Any opinions one the new mil compared to the pervious gens?

6.7 Cummins
 

They shoot flame out the tailpipe, but I don't think of that as a problem...really.

I want that mod!:up:

I used to run a old big cam 400 cummins that shot about 6-10' of flame out the stacks after we turned the pump up 47%. she'd climb the grapevine at 55 mph+ grossing 80,000 but need to be inframed every 100,000 miles or so but she was fun to drive.

So far, I have only heard of one, and that is only that you actually have to run the truck to burn the crap out of the particulate filter. But we all know a diesel has to be run anyway. :w2: :w2:

yea that's the big deal with it...you have to get it out and run it to clean out the dpf.

well i heard one the other day, the cylinder walls are not all even thickness so that if you romp on her cold you can warp the block but if she is warmed up you are good to go

I have one the main problem is the throwout bearing. i can feel it in the cluch. the dealer called up mopar and the said im going to be a test dummy.

I have had mine to the dealer 3 times for check engine lights. All three were turbo related. A faulty turbo code (no problems found), and twice for carbon build up in the turbo. I love the power and feel of the truck, but these trips to the dealer are starting to irritate me. The service tech told me to drive it to and from work once a week (70 total miles with only 4 stop signs) in tow/haul mode. That might help to clean out the DPF. He said the other option was to run it down the highway for 15-20 minutes at 65 mph. I guess I don't really have a choice. Diesels need to work...they are not meant to be grocery gettters!!!

Ditto! I have had mine at dealer several times for the same damn thing. Some turbo code. Nothing seems to be wrong tho. Runs great specially now

I have heard alot of people love pulling trailers with them. They say the bottom end TQ is great. I've not heard of any real problems though.

4000 miles on mine and it's yet to even have a regen cycle.
I run it decently hard though so maybe that helps.
17mpg empty 14 or so towing. Not as good as my 2000 but acceptable.

The real selling point is the 68RFE. That and the integrated exhaust brake.
We'll see how it holds up to plowing this winter.

I'm curious as to how you figure it hasn't regenerated? Unless you have a programmer that can tell you (edge juice) it's almost impossible to tell. Although one way is when your overhead mileage starts to drop.

BigD

so far ive had mine at the dealer twice now and im taking it back tomorrrow for check engine problems ive got a cold air intake and banks exhaust on my 6.7 and it runs great tho fuel mileage sucks but im worried that the intake and the exhaust will void my warranty what do you guys think

If you had the stock intake and exhaust still, I would be safe and throw them on. Otherwise just hope and pray you have a cool dealer that is mod friendly.

I think the 6.7's basically got all the kinks ironed out of them. I do still hear of DPF's clogging on them, but hey you can always delete them.

The 6.4's seem to be doing fairly decent, they have some problems with them, but nothing to catastophic. I've heard of a couple quite running, but not very many. Its just when you go to sites like these, you never see a thread talking about how you love your truck and have never had a problem with them, they are mainly filled with questions, and problems that need diagnosing.

This is how I take it. I see lets say 10x more problem threads about the new fords than the new dodges. But around here, there seems to be around 10x more 08 Fords, than 6.7 cummins. Just how I look at it.

The the way, my parents have a 2008 Ford F350 6.4/auto CC LB SRW 4x4 Lariat all optioned out. That truck is a beast, whenever my truck is down, I get to drive there's. I must say that is the only good thing coming from my truck needing to be worked on (it hasnt ever broke down on me, just needed to be worked on, like when I drove 50 miles with a grenaded turbo making a max of 1.5psi at WOT at 70mph, when that is usually 9psi, it just needed to be fixed, it didnt make my truck stop running). Anyways with a full amount of fuel, and me in it, it weighs a schosh over 9300pounds, yeah, its a little on the heavy side. The best fuel economy I have seen was about 17mpg, but around here we only do 60+-mph on the freeways. There truck has 6000 miles, and the only problem with it was that the powersteering/brake pump was acting weird (hard to explain, but when you depressed the peddle, the peddle would feel like it was vibrating, same with turning the steering wheel. I day later and at a cost of nothing to us our truck was back up and running. Its grossed over 19K pounds going over mountain passes, and has enough power to pass basically anybody up. Its a great truck. Truth be told, for what we use it for, it was the best choice. Looking at the new trucks, the fords are the heaviest hands down, I'm sure most will agree. We use ours to haul a camper and boat around, and with the high center of gravity with the camper on, its good to have a lot of weight on the bottom to keep things safe.

Mine was just in the shop last week for "hesitation". When I get on the gas, and not hard, it hesitates, and kind of sputters, and then it takes off! I do not notice any smoke, and sometimes when I turn on the engine brake, it fixes the problem. I have installed an afe airbox, and a muffler delete magnaflow, and when I hear the "little" rumble out of the exhaust I know it is going to run great! But when I do not hear it, it runs like shit! Sometimes I can drive it for 5 minutes, shut it off, and then start it and go again and that solves the problem. Any suggestions? It is an 08' Megacab with 3900 miles.

Apparently, grenading a turbo means something very different to me than it does to you. I have seen some turbos go, and believe me, when you "grenade" a turbo there will be no more boost, let alone driving at 70 mph.

Ask em and see what mods they will void the warranty with, before you bring it in.

I have about 5000kms on my 08 so far and no issues to date. I have left it all stock and not messed with anything to this point and I have been thrilled with the power and I absolutely love the new tranny and exhaust brake. I did put 35" toyo m/ts on it and it will roast em stock so I cant imagine what it will do once I start messing with it!!!


I am even getting decent mileage so far, and as far a regen...if it happens, I dont know anything about it. I know one thing that is freaking me out though! You can run your finger around the inside of the exhaust pipe and it will come out clean...not a speck of soot anywhere...very strange!

Well, my bearings seized up in the housing, the shaft was bent some, intake wheel hit the housing and sent a lot of the wheel into the intake (a lot of big pieces got caught on the intake screen that they come with the factory with, though I'm sure some got through. I have around 4K miles now, and no problems, so I dont think much happened), exhaust housing bolts fell out. Lets just say it wouldnt make any boost at all unless WOT, and even then it would hardly move the gauge. I was just saying that it was down for repairs, and not really broke. I'm sure I could have driven like that for a while, until the turbo actually let go.

well the good news is i got my truck back from the dealer and all that was wrong with it was o2 sensors and they didnt care at all about the aftermarket exhaust and intake that i recently installed it was never even mentioned. but no mattter what my 6.7 is unstoppable she runs like a raped date emty or loaded.

24hrs. and 900 miles into my new truck and no problems yet.....knock on wood. Just wish I could keep my foot out of my Edge w/ Attitude so I could see what kind of mileage I'm going to get until he's broken in! :run:

I was about too buy a chip for my2007 ram 3500 6.7 cummins and im just wonderin if the bully og is a good buy or not what do you guys think

My buddy went through 3 turbos in 100k,the techs kept fixing the wrong thing,can't recall what that was,wealth of information eh?
I think it's fixed now.
