Ill educate you. Every single problem that was listed above is the some of the very reasons not to even buy a diesel truck of any brand. Speaking from experience here. I have owned 2 Dodges, A Chevy and a Ford Diesel in the last 10 years. I am now back down to a 1/2 ton King Ranch. Diesels trucks were a never ending pocket book drain on maintenance $150 oil changes, bigger tires cost more, constant problems of some sort, had to have programmers to make them efficient and run correctly, then you have voided warranties, ERG valves, ECU's, DEF cost and issues you name it, just like everyone else posted. Why do that to yourself for no reason? If you pull a 40ft float daily or have some kinda long haul business that's different. But if you are a weekend boat and trailer puller its a waste of money and took me forever to realize that. I'm back down to factory 22.1 MPG gas burner with a $40 oil change and no other maintenance issues. I sat and added the total real cost of owning a diesel over 5 years(length of most loans as a reference) versus owning a gas burner over the same time frame. Real numbers saved payed exactly half of the loan for my Gas Burner. I thought I had to be wrong, had my CPA look at it too, He punched numbers around and agreed I could have saved right at $26K by having a gas burner over the same life of my Diesel same loan terms when you add in real cost of ownership over same period. He had actually told people that before and no one listens, they just want to blow and go and dicck measure with black smoke diesels. It really is insane. Rarely do I find the need to have a diesel to "PULL" anything my gas burner cant. At 26K in savings its hard to justify every owning one.

And you didn't even break anything

My favorite thing to tell people is I know a guy who wrote a check for $8,000 for a fuel system repair on his '13 Ford diesel.

Well I'm pretty convinced to stay away from diesels. I never saw the need for one but looked at them from a resale standpoint.

I guess I'll focus all my attention toward the 6.0s of the world. Are the 6.2L f250s worth a damn? I know the f250 5.4s are not. I've driven one and was very underwhelmed.

I really appreciate all the input. All I've read was not as good as the feedback here.

I'm an Admin on a GM diesel forum and this isn't anywhere near as common as you make it out to be by the way you worded it in your post...and I read thousands of posts weekly. Prone would not be the proper term to use for this anomaly IMO

have had 2 in the last year at my little shop
with this issue and if it wasn't so prevalent then why are people having hard times locating uncracked cylinder heads?

I have 2 sets of heads in my garage that have been on full race motors without any issues...

The LLY's that some are prone to overheating in Arizona dessert type climates seem to be the only link...correct the cooling stack(yes that is an admission GM should have done better) or change to the LBZ intake horn/mouthpiece...how many are going to admit they may have overheated their trucks bringing about the issue?

as far as finding heads? How many trucks are still on the road? how many have reached their useful life? are there really that many LLY's in the recyclers stripped of their heads already?

Honestly, I don't believe there are that many that have been retired...

also take into consideration that most duramax forum people are there to "Mod" their trucks...If you take into consideration the hundreds of thousands sold that weren't "beat on" we wouldn't even be having this conversation on the use of "Prone"

The Ford 6.2 gassers are very good, especially with the 4.30 gears. You gotta realize what you're getting though. It's a big heavy arse truck with low gears and a big, tuned down engine. It's going to drink the hell out of fuel and you'll have to put your foot in it to get 15k pounds moving, but it'll do it and it'll last a real long time doing it.

I sure as hell ain't moving 15k but that's good to know its worth a shite. I have a lot of digging to do. I live close to work and so long as I pay cash I don't mind shite fuel mileage as long as I'm not paying a note. I just remembering how much of a dog the 5.4 was in that platform

Thanks

The 6.2 is a far more capable engine in an HD truck than the 5.4 was. It still won't win any races but it does come with the same driveline you get behind the diesel, so it should all last forever (again, at the expense of horrible fuel mileage). The new 17's offer some awesome features for an HD truck and I'd be hard pressed to pass that up if I were in the market, even though the chevy 6.0 HD driveline is proven bulletproof.

Is all your experience with the Duramax platform? Doubtful

most ASE guys are just parts changers...

they keep changing parts until they get it right


seems you probably went to the forums to get some answers yourself...so much for 20 years

Dad just got a 17, lariat, 6.2. Truck is super nice and pulls really well. Like people have said it's not going to win a race but it works. We pull his 38' camper to dega and averaged 7.8 mph pulling it 65-70 mph. He only pulls a few times a year so it didn't make sense to but the diesel. And this is coming from a gmc guy.

My current truck is a 3/4 ton Chevrolet gassed with 250k very hard miles on it. I just had to change the transmission and brakes within the past 6 months. That's a badass truck. If I were buying one today, it'd be a Ford gasser.

That was hammer time that kept blowing the Ford up.

My diesel is a Volkswagen, and I can't say I'm getting screwed on it with a straight face
