6.7 longevity...How many miles do you have and what is expected?

I have a 97 7.3 and I know that they are expected to last a long time and many, many miles. I was wondering what I could expect If I dropped the 50 grand or so, for a new 6.7

TLHort on here has 195K or so. There was another post on here for a guy with 167K and his motor let go.
I'd like to here from anyone who has more than that. 200K plus.
Posting less than 200K miles is not noteworthy when the question is about longevity.
The trucks have been on sale 32 months so maybe we have some road warriors like TLHort with 200K and more can let us know how Ford's new diesel is stacking up against the 7.3.

I would think 200k is very doable. with the drivetrain warranty on the 6.7 good for 100/5 yrs, if all is well and maintained very good, why wouldn't it go 200k? If the head gaskets don't go, or tranny clutches dont' give out could be a piece of cake.

I do see too many electrical/programming/ECU type issues that regardless of the mechanicals of the truck, are its limiting factors these days. Fuel system contaminations, DEF programming/signal issues, etc...

Does anyone know, how many miles Ford built this engine to last? 225000,250,000? I would think anything less than 250 for a diesel would be ridiculous.

I am pretty sure I read a post a while back from Corey that said they are tested to 250K. Not sure how much that says though, the 7.3 was probably tested to less than that and they can definitely go longer than that if maintained properly

When researching mine before I bought I read an article somewhere that Ford ran its test mules to 200K mostly trouble free.

As a normal owner it is miles/time. 200K in 2 years has got to be easier for the truck than 200K over 10 years if you ask me.

I have a bumper-bumper warranty from Ford that says my 6.7 will go 200k without a breakdown or the repair bill belongs to Ford!

Ford does NOT offer a "Bumper to Bumper" 200k mile warranty. If it's a Ford plan what you were sold was Diesel Care. Hopefully you got the Diesel Care Plus as the standard plan doesn't cover a whole lot.

As a VERY high sales volume Super Duty dealer and being located on a major interstate (I10) we tend to see more trucks than most dealers.

I personally have delivered/sold OVER 400 of the new 6.7L PSD's and to be honest, the return to service after sale is VERY VERY slim compared to previous model years. As a matter of fact, our diesel techs, 14 of them currently here, plus their helpers, are truly afraid for their jobs. Most of the 6.0L's are out of warranty now and are taken to non-dealer shops and the 6.4L PSD's are not breaking as often as the 6.0l PSD's. It's just so odd to walk down to the diesel department, which consists of 25 or so bays, and see it somewhat empty....

As far as major repairs, IIRC, we have done (2) engines on pickups and (4) engines on chassis cabs (valve issue). One of the engines was replaced due to an oil leak, yes, an oil leak and the other one was replaced due to a connecting rod bearing failure that we determined was over torqued at factory. We just did our 1st transmission last week and the truck had just under 100k miles on it. I don't recall exactly what the failure was, but something internal came apart and was making a noise. We have also done a few turbos, maybe 4/5.

Of course we went through the NOX sensor failure spell and have done a few DEF tank pump/sensor replacements.

All in all, the 6.7L PSD has proven VERY well. I have a few commercial customers that have broke the 200k mark and the trucks are still going strong.

WOW Guys Thanks!

I didn't know all that about these trucks. If you have seen my sig then you know I have a 7.3 (and with ONLY 135 K.) I was wondering if it would be best for me to sell it to some deserving soul and get me a new truck. BUT at 50 to 60 grand I was wondering if it would be worth it? My old truck is very comfortable. BUT these new ones are .....GREAT

When they dropped the manual transmission option, they dropped any new Ford from my wish list forever. The transmission will be the limiting factor for mileage. I doubt many will ever see 200k miles. Better off keeping the 97.
