Default Diesel peeps..... 6.7l Question / advice

Looking at a used 250 with one.... 1 aspect of this truck is a bit of a turn off for me is that it has 3:31 gear ratio. Its leveled and has 35x12.50 tires on it so wondering if the tall gear made even taller with oversize tires would be a concern towing routinely ? I most likely would never be towing really heavy loads, test drive went well it seemed to have no issue pulling itself around and felt peppy.

Another bit of advice Im looking for... its currently at a non ford dealer and I told the GM that I would not purchase unless I could get Ford tech to give the motor a health check. Anyone know exactly what I should request ford check and give me a report on if I get that far? Is it similair to a 6.0 in using various temps as an indicator that things are going well? Also wonder if they are able to report on the past regen status ?

Nothing like the 6.0l. What year? The 6.7 has evolved a lot since it’s inception. In ‘17 the fuel system got revamped and since then the fuel delivery issues that all the PSD naysayers talked about all but vanished. Very strong, very reliable engines. I’ve had zero issues with mine.

Ford has turned the ‘20’s up to 475hp and 1050lbft of torque. It remains to be seen how the new 10spd transmission holds up.

I have a 2007 6.0 and 2010 6.4 and a 2017 6.7. The 6.7 is a beast. The 2017 is really bulletproof. Take it to any Ford dealer, just have them hook it up to a computer and run the full diagnostic. You will get engine and transmission info, more than you want. Engine hours, injector condition, tons of crap.

Depending on what you are pulling the 3.31 gears won't matter but they will help gas mileage. I have 3.73s in the 2017 6.7. I pull a 40' horse trailer at 24,000#. Barely know it is there. Gas mileage sucks. 10-12. The 2010 6.4 has 3.31s. Pulls the same trailers but gets 14-15 mpg.

I have the exact same setup pretty much. 2012 f250 ccsb 4x4, 2” level kit and nitto terra grapplers that are about 34”. It towed my 25 center console with ease but it’s a fairly light rig. I also pull my 2017 jayco 32 camper which is around 8900 without any issue. The transmissions in these trucks is so well suited for towing, not a lot of unnecessary downshifting and hunting for gears. I get around 10-12 towing and 16-17 unloaded depending on how I drive. I’ve had the truck since new and currently have about 124k on the odometer

What year?
Look at the engine history and changes throughout the years, and make sure the problems have been addressed, or try to negotiate a price reduction for the repairs or improvements. Is it deleted? (nevermind-I see where you asked about regen). In other words, has the DPF and EGR systems been removed? Probably great for the engine, bad for you if ever forced to return it to stock. Oh, and as far as the transmission, you really don't hear of ANY issues. I think the '17s had a recall for the parking pawl.

My biggest concern was all the emissions equipment. Here are a few things you may want to know. I looked all of this up and am not an expert. Some are my observations as a newish diesel owner. Veterans feel free to correct as necessary.

There are 2 types of DPF regenerations, active and passive. Passive regen occurs when the exhaust gasses are above a certain (high) temperature and uses no additional fuel. This occurs when the engine is working hard. Active regens kick off at a prescribed frequency OR when the engine management senses the DPF has reached it's capacity. Active regens do use some extra fuel and in my 19 seem to take 15 or so minutes.

The DPF will try to perform an "active" regen when the DPF reaches 99% as indicated (this display is an option you can have a Ford dealer activate in certain years- I have a '19 and turned it on myself using FORSCAN and an ODB2 interface cable). When not towing, not enough heat is generated for "passive" regeneration to occur, the DPF% full with go upward slowly but steadily and you will use very little DEF. When towing even a light trailer of 2500lbs, the DPF % full increase rate slows down I suppose because the engine is making enough exhaust temperature to allow some passive regen to occur. It takes a while for the engine and exhaust to heat up enough to satisfy the required parameters necessary to kick off an "active" regen. For this reason, a diesel may not be the best choice for short trips. If you are able to monitor the DPF% full, you can plan your driving accordingly, so that when the computer kicks off an active regen it will have time to complete (15-20 minutes) before shutting down, without having to needlessly drive just to clean the DPF.

Exhaust Gas Recirculation (EGR) cools the combustion event since the oxygen in the exhaust gas has already been used. The EGR system reduces the production of oxides of nitrogen (NOx). It also sends some soot back into the intake.
A hotter combustion event is better for power production but will increase the production of (NOx). DEF is used in the SCR to remove the remaining NOx from the exhaust.

Diesel Exhaust Fluid (DEF) usage will increase to reduce the extra NOx produced when towing heavy (high combustion temps), but you will have fewer if any unprescribed active regens since exhaust gases will be hot enough for passive regen to occur. The DEF usage allows Ford and other manufacturers to use less EGR, and tune for more power, thus allowing more heat and more NOx to be produced since they will be removed by the aftertreatment. If you can't delete, DEF is a good thing.

The exhaust is REALLY clean and all you really smell is a hint of ammonia from time to time. Once I learned all of this, I felt a little better about the scud missile we are carrying around under the truck.

Good luck!

They got it all worked out right in ‘17. Get it checked out but it’s probably going to be solid.

The new 250's come with a 34.5" tire so 35's won't make a difference

I have the exact truck that you are describing. It tows my 11k lb travel trailer just as easy as it tows my flats boat. It gets average 10mpg towing the camper and 15mpg not towing. I added airbags to the rear since I had a in the bed camper that weighed 3500lbs. I have 35k miles on mine now and the majority of the time it's towing something. Great truck, plenty of power. I lost 1mpg leveling and going with a 35x12.5 tire, but I don't miss it.

Most places now let you take a used vehicle overnight. Take it to Ford the computer tells all. Motor on the 17 has great power you will love it.
