Good and Bad Years?

Are there any good or bad years for the diesel motors, or anywhere else, in the F250's and F350's? I'm looking mainly at the '08's, or higher if I it's a good price. But if I can find a nice '06 or '07 for a lot cheaper I may consider going that route. But I'm hearing that there are some bad years. If this is true, which years are good and which are bad?

From 2003.25-2007 Ford used the 6.0L diesel. This motor has some problems, but many were fixed by 2005. Personally I would rather buy a 6.0 and fix it to be reliable rather than a 6.4.

Are there problems with the 6.4's? The 08+ body styles are definitely my favorite, but I don't really wanna buy problems either.

Problems? Not wide spread. But they dont get very good mileage. I like the interior of the 08-10 best, but the 6.4 just doesnt grab my attention. A 6.7 isnt much more expensive, and at least with a 6.7 you get decent mileage and a lot of power.

The guys at the Ford dealership didn't exactly sing the praises of the 6.0 and said I'd be happier with a 7.3, time will tell but I went for a pre-6.0 truck.

The ONLY years I would look at getting are 2002-2003 7.3 personally. Everything else has 'known' problems, if not headgaskets and EGR its bad fuel mileage bad turbos or **** tanks to keep full.

Agree - all the 6.X engines have known issues of some sort. Problem is the newest 7.3 is now 8 years old so finding a good one is getting tougher. I 've contemplated getting a late 6.0 and transplanting a 7.3 into it. Get the newer style susp & body w/o the engine reliability concerns.

I have the 6.4. It is a pretty good motor.

Most of the issues do center around the mpg's. This is a heavy truck coming in at 8K or more for most people. Combine that with the emissions and it can be an issue.

Alot centers around what your use would be. This motor works great for towing and long distance applications. This is where it shines the most and will do the best service with the fewest problems.

Just running to the store or a lot of city driving and then you will have some issues with the EGR or the DPF.

So the real question is what would you use the truck for?

Problem areas for this motor can be the radiator seams, not ever an outright failure or any thing to leave you stranded, rather a slow leak. Seems to be a problem for the 6.7 as well. Cheap design.

EGR valve...they did come out with a redesign so you don't see too much of that anymore.

DPF. The DPF traps soot which has to be burned off from time to time. Slow speeds/city stop and go do not work well with this.

Heard the same from folks around here - the 6.4 & 6.7 don't like stop 'n' go driving. Better off work'n them hard all the time - they seem to do better when they're run that way. That's what worries us - our app (farming) works'em pretty hard but includes quite a bit more idle - low speed ops than most. Granted they're loaded but we might only be going 10mph. Worried we wouldn't regen enough and have issues.

Are you dead set on a diesel? You can get a V10 for cheaper and have a lot less problems. The only down side is fuel mileage. But fuel cost is less and so is maintenance so for me its cheaper to own the gas burner.

I have a 2003 6.0 that I bought new now with 145,000. I did have some problems innitially, egr sensor, wires chaffing, an oil leak, and one failed injector. Since all that has been repaired I am really pretty happy with the truck. It seems all these trucks have some issues so pick your poison. the mechanic that works on my truck seems to think the 6.0 is one of the better ones to go with. These are expensive trucks to own and operate but so far I am hanging in with it. Truck seems to get a consistant 15 mpg.

In this case a DPF delete and tuning will cure the issues.

But they don't have the 6.7's until like 2011 or something right. I can't quite afford any of the new new trucks, I'm trying to keep a bit of a budget.

I don't really wanna go backwards though. I just sold my '03 Expedition for a truck, and want to get something at least a few years newer.

MPG's isn't a horrible issue, anything will be better than what I had in my expedition up until right before I sold it. And I also wouldn't be driving it daily, only when it rains or when i have another person with me. Or any other reason that I wouldn't be able to ride the bike.

So the real question is what would you use the truck for?
I wouldn't be doing much towing, maybe occasionally, but not often. Just mainly for rainy days or when I have something that I can't take not he bike. And occasional off roading. Are there any kind of mods than can be done to either the ERG or the DPF to help with some of the problems.

Would the delete solve some of the issues.
