Hey Guys,
I've got a 02 7.3 and been looking at the 6.7's for years now, lol. Wanted to get everyone's options of how they like the 6.7 and if there are any real issues that plague them. I know to stay away for the 11's and that the 15-16's have a regen issue. My daily drive is 8 miles in town one way, my 7.3 gets up to operating temps about 3/4 of the way so that shouldn't be an issue. I try to do my own maintenance and looking at these new trucks it will be more difficult compared to the 7.3. I'm looking at a getting a used truck, staying in the 13+ years. Any and all comments/opinions welcome. I've got 178000 on the odometer now, next largest maintenance items will be injectors and trains in the 200K area my guess.

Thanks

 

Welcome Andrew! Other than the similarities of looking like each other, that's where they end. Nothing common between a 7.3 and 6.7. My daily driver is a 7.3 Excursion so I know. The power of these things is ridiculous.
I chose to drive my Excursion as to not put many miles on the 6.7, but that's another story. For that many miles in the morning, you will have to take it out and run it down the highway occasionally as it will have to do a thorough regen at times.
You will have to be a little more selective on where you buy fuel with the 6.7. Buy only from high volume stores that sell a lot of diesel. A little water will kill the injector pumps on these trucks. Change your fuel filters 15k. I was changing oil at 5 and fuel at 15 until talking with all the others here. The truck will let you know when to change the oil, fuel will stay at 15k.
The 13s have bigger brakes than the 11-12s. On a fully loaded truck, the 14s have a rear heated seat over the 13s. I love my truck and I believe you will too. Read the TECH FOLDER of this thread when you have time to do some reading. It will help out a lot.
Others will be along shortly to offer more insight into these beasts!! Good luck in finding what you want.

 

You should get the correct tool for the job, an eight mile commute is not much more than a bicycle trip.

The valve issue was on 6.7 trucks produced before April, 2011. The exact date can be found in another thread.

 

I would not trade if all you do is a eight mile commute.


Now if you can keep the 7.3 for the commute and then get a 6.7 for your long runs and towing that might be a consideration.


The emissions stuff is your real issue here. It needs to get hot to be trouble free.

 

Thanks for the input thus far. That is my largest concern by far is emissions and the drive time. This would be my DD as my 7.3 is currently. I do tow and haul stuff, that's why I want to go with the 6.7, it's just not a part of my daily drive. Keeping the 7.3 and getting a 6.7 is a no go, can't keep both due to costs. Does anyone DD there 6.7 like I would and have input on emissions issues?

Thanks.

 

I too came from a 7.3, and have not regretted it at all.
I'm at 89,000ish miles now, my 6.7 gets daily driver use as well, driving 12 miles to work, and getting run hard on weekends. Has been better by every measure (economy, service, repairs) than my 2000 7.3 was at this point.

 

Hey Andrew nice to hear your looking up from the 7.3! The only thing I have missed from mine is the ability of not being able to turn wrenches on the new beast. My 6.7 gets daily driver use as well, my commute is 15 miles to work, and she gets to stretch her legs on weekends. The economy is not as good as my 7.3 due to the 7.3 being DP Tuned but the way this beast runs and tows I don't see the need to have it tuned.....yet

 

I came from from a 7.3 as well. 6.7 is a beast, much more refined and lots of power. I daily drive mine, about a 10 mile commute one way to work and it's been fine. As far as being able to work on it; you can pretty much do all the maintenance stuff like you would on the 7.3 at home.

 

Thanks for the comments, good to see that others have short commutes and no emissions issues.

Is there a thread on what to look for on a used 6.7 truck?

Thanks again!

 

I do a lot of short drives - truck is "smart" about the regens. I take the kids to/from school , grocery getting, etc... I do long drives every so often and tow occasionally, but not regularly. If you told me you had a 1.5 mile commute and never went anywhere else, I might be worried or I would tell you to plan on an occasional long drive. The truck will tell you if/when it needs this long drive as well. Although I have only seen a drive to clean once and that was in 2010 on my first 2011.

I had several 2011s before this one and a 6.0 before that. I've driven 7.3s as well, but never owned one. All of the 6.7s I had were great. (I can't say the 6.0s I had were great) I would never go back voluntarily...

You got a good handle on what to look for. Personally, I'm not a big fan on having any of these trucks without a warranty, but that is me and I have a LOW risk tolerance to large out of pocket repairs. I prefer payments, easier for me to budget, especially now that I am on a "fixed" income. I do my own maintenance and how Monty does his.

Since you are in a cold state, here are things to look for. Block heater, rear defroster on the sliding window which was an option early on, rapid supplemental heater option is really nice too. Rear seat heater as mentioned (my kids like this and some here use it to keep their jackets warm). Ohh and a heated steering wheel, which up until 2017 was only available on a platinum level truck and not sure what year...

 

cold climate the supplemental heater and heated seats are a must with a short commute.


You will use the seat heaters a lot as they will get warm first.

 

Your temp gauge is basically an idiot light. Despite your indicator needle pointing normal almost certainly your 7.3 is not running at 203 F at 6 miles from a cold start and your oil temp would not be above 185 F.

 

Actually, having AE I know my temps. And yes, about 3/4 of the way to work they are in operating range. I was curious again today and with it being 50 out this morning I was right at that on my drive in. In the winter (where's the snow?) I keep the truck plugged in and on a timer so my temps will be around that in the morning regardless.
