I need a reality check...

Ok, I have a 2011 6.7 and have had only one small issue with it that has nothing to do with the motor. I came to this forum as a preventative measure and see what other owners are seeing for issues. I was amazed by a few of the issues currently on the board that deal with motor issues. As I read them, most engines that have had problems i.e. blown motors, turbos, etc. had a range of modifications to them. Some were just chipped and some were completely overhauled. So here is where I need my reality check... It seems that the best way to keep your rig running for a very long time is to change the fluids with motorcraft fluids and don’t change/mod anything... Accept the 800 ft lbs of torque and if you need more power, buy a semi. I know some people would hate to hear this but ford put about $600M into research for this engine. Did your mod company put that much into their research? I use mine to pull a 10k lb camper and it does an amazing job at it. I can set the cruise at 65 MPH and I do 65 up or more importantly down hill. It is a amazing truck if you use it for what it was designed for. Am I off on something here?

Okay, I am sure i speak for at least a few others,
I tuned and deleted mine cause i was sick of seeing a check engine light on my dash - problem wasnt a nox sensor but a calibration issue, I had given up after 4months. Turned out it was a cold climate issue.
Myself like others arent comfortable with this DEF/UREA/REGEN system. if 1 single sensor fails the truck wont run, let the diesel breathe and personally i need this truck to be reliable everyday, not to sit in a dealship being troubleshot. I have 80,000km since tuned/deleted on my 2011 without a problem with the engine. Sorry if this may seem like a rant nothing personal , just felt like voicing my opinion.

Understand your concerns. I was skeptical at first as well of the DEF. I have learned to enjoy it and trust it. The argument could be said as well, "If one thing goes wrong with your “fill in the blank” your truck won’t run as well". I live in a cold climate (Not as cold as Canada) as well (Montana) and had some crazy things happening to my truck. Nothing that falls into the reliability column.

I have been in the Maintenance world for a very long time and have learned several things over my time. Preventative Maintenance should be well over 95% of your maintenance. The quality of engineering and manufacture is determines this percentage. Corrective maintenance is much more expensive. Injecting unknown factors into your systems equation normally leads to an increase in your corrective maintenance. If reliability is what you seek, I would not introduce unknown factors into my system. Your list of mods below your post tells me being reliable is not all you are looking in this truck.

My thought exactly !!
This is why I traded my tuned 6.0 for a 6.7...I want plenty of power to tow and reliability of a stock vehicle. I will leave this one stock for sure and the DEF thing is cool....I do not miss the smoke and smell at all.Plus this thing is plenty fast for a 8000 lbs beast !!

In my opinion if you run a stock or tow tune with the emissions deleted and a free flowing exhaust your going to get a lot more mile out of it then if you left it stock

I say if you pay 60+ K for your truck you can do what ever you want to it.

Agreed. One thing that started annoying me about my dealer is that after I bought my truck I removed the dealer name sticker from it and when I would take it in for servicing they would put another sticker on it which I would again remove. After the third time I went to the manager and asked him how much he pays for a commercial spot on TV because I want the same amount of money if I'm going to be driving around advertising his dealership everywhere I go. He had someone remove the sticker on the spot.

Absolutely! You can do whatever you want with your truck and your money. Agree 100%. Should you do it however, is another story in my opinion.

I guess no one worry about warranty anymore !!
I just like to keep mine warranty specially for this 60k+ truck !
I've done mods on past vehicles I've owned....but I'm done with all the bull.....too many smog laws to deal with.

I deleted my 6.4 5 years ago, no egr no dpf and guess how many times its had to go to the dealer for service or warranty repair. That would be a big fat ZERO, just saying.

I've seen 6.7's fail both stock and modified so that either tells me the design of some components is flawed or no one that owns one knows how to drive it properly, I'll let you figure out the more ridiculous assumption.

I can tell you the current design of EGR systems on diesels are very flawed as well as the DPF systems ( why do you think DEF came along ), there are other options out there to reduce emissions without impacting the reliability or performance of the motor that also have no negative effect on mileage. How ever the manufactures don't implement these systems because they cost more to produce, even though if they just figured in the warranty repairs for failed emissions components or other failed parts do to poor emissions equipment design they would come out ahead. The current setups are nothing more than band aids, they cause excessive heat to unrelated parts, thermal break down of lubrication, fuel dilution of oil, accelerated wear on the piston rings and valve seals, shortened life of the catalytic converter and DPF if used for towing regularly, no start condition if DEF runs out, DEF range is shorter than advertised, and last but not least very poor mileage. Now some of the mileage loss can be contributed to the switch from LSD that had 500 PPM sulfer content to ULSD which is only 15 PPM, but mostly to the fact that fuel is used to clean the filters during regen and that is fuel not used to move the truck forward.
