Which diesel motor is more dependable?

[Crusadernoob]

Yes it is, but im not looking to pay upwards of $70,000 for a truck and question its reliability either. Sure lots of good fully equipped emissions intact trucks on the road, but also some good pre exhaust emissions trucks on the road that dont “roll coal”

Well, one volcano popping puts out more junk in the atmosphere than humans have in the last 100 years. And everyone seems to forget that big plasma ball in the sky that has more of an effect on global climate than anything else. One can indeed improve some local conditions with emissions controls, like LA or the front range of Colorado. But to actually think mankind can have a major impact on global climate is arrogant hogwash. Only those scientists who derive their funding by adhering to this sort of stuff believe it. Just the few semesters of science related courses I had in college was enough to see how the global warming idea is full of holes like Swiss cheese. Only back then, the scare du jour was global cooling. Schizophrenia is alive and well in the scientific community.

True... Except they cause so much trouble many people opt to delete them rather than keep fixing them.

Ive yet to see someone get stranded from an EGR valve. FWIW an LB7 with a 5 speed gets it done too, no EGR, not even a PCV, but injector problems galore, whole other story.

I'm taking about pre tier 2 emissions.
Compare an old school mechanical injected diesel with a modern 4 valve common rail injection diesel and yes... The old stuff was sluggish.
You can disagree if you want... It won't hurt my feeling.

No doubt, I had the displeasure of running an old 6.9, then “upgraded” to a 7.3, both slugs, will run forever, but wont break any records. I agree. My point is that we've got a lot of great trucks to choose from between then and now. Ford couldnt decide what engine to go with 6.0, 6.4, 6.7. Ram has done some tweeking, GM has stuck with the 6.6 and didnt have a major revamping until 2017. All 3 made some great pulling machines WITHOUT any serious emissions updates. Some years better than others for all, you just need to know which ones to buy. Any one of them can and will break down, but im not going to be on the side of the road for an emissions problem.

back to the OPs original question. I have had ford and Ram (currently) all are good provided you do the required maintenance.

Ford didn't make the 6.0 or 6.4 those were thanks to international.
They had 100 changes to the 6.0 in the first year, they had so many problems with the 6.4 and fighting between Ford and international over who was responsible they came up with their own design ... The 6.7.
Side from a few broken cranks in the first year I haven't heard of too many problems with the 6.7.
The Cummins send to be the most reliable, but the Duramax injectors also seem to have been sorted out so now we have three solid choices, I just don't think EGR is good for diesel engine longevity.

[Crusadernoob]

Correct, EGR and PCV make tar. A $20.00 blocker plate and/or a PCV catch can.
Correct on the whole International and Ford, Ford is better off now. I love a Cummins, ran them in off road equipment, I’m sure the LD truck version is great. Duramax injectors were fixed in the second engine model, no problems in over 10 years.

Deleting the EGR can subject you to a $10,000 fine.

Yes it can, but as far as emissions go I’ll take an EGR and PCV over all that other “stuff” it wont leave me stranded!

That fine is for aftermarket manufacturers, not consumers that modified their vehicle.

That's why whenever you buy those parts you have to say you're aware there only manufactured for "of road use"

So far there have been 4 different EMISSIONS Control changes to the Diesel engines mandated by the DEQ and some of these changes required multiple revisions to get them right, which may have taken till the next release of the NEW emissions package to finally correct those issues, but then the New release engine started the process all over again. The years of truck to stay away from are the 2003-4, 2006-7, 2012-13, 2016-17 and 2019-20 will be the next ones to stay away from, these are the LATE Production year plus the next full production year. It is funny the Europeans can produce an engine that can run circles around our engines (mileage wise) but we are more concerned about the emissions instead of just increasing the efficiency so we burn less fuel to begin with.

Just remember all manufacturers can produce a LEMON at any time and the unlucky will always get it. I purchased a 92-3 Dodge (New Body Style) with Cummins and could not get near what everyone was claiming they were getting hauling great big 5th wheels and I was running as an empty flatbed.

You haven't looked very hard if you haven't found the merits of specific motors. That is because you have Cummins, by far the best diesel in any pickup, and then you have the rest. Funny you haven't run across that way of thinking. Cummins is a straight 6 diesel, like most big diesel truck motors, and the other two are V8 bastard diesels, one being an Isuzu and I don't know what the other is. There is a reason Cummins Turbo Diesel 6.7 are still straight sixes, but it would take a diesel expert to explain it, which I am far from being...

While technically true, no one is really checking. And many locations have no emissions testing of any kind, so it would not be checked. Now, the powers that be have tried to force dealer shops to revert and reinstall all emissions on those that have been deleted, but not very many follow thru on that. But warranty is shot if one does this stuff. The OEM has no problem absolving itself of any responsibility to fix the engine under warranty.

On the straight 6 deal, it is all true. Heavy truck diesels took a few shots at doing V diesels in them many years ago, but it never was accepted and died off pretty quickly. Every heavy diesel is a straight 6. They prove to be easier to work on, more reliable, less complicated, etc.

If you buy a tuner for a deleted truck you have to give them your VIN#. Not sure what that means though.

Probably means that the deletion will be reported on the carfax and / or title.

The tuner will be for your specific truck so they want the VIN to be sure you're getting the correct tunes specific to your PCM strategy.

Really, hope you're kidding. That is the farthest from the truth.

First time I have ever heard of this. This is a new one on me.

I have a Smarty and it is VIN locked but only when you install a tune on the truck. When you uninstall the program the VIN lock is removed from the tuner and can be resold to someone else.

Really! This is how fake news originates on the internet.
