Great addition to the content on your channel. Look forward to seeing more segments with him.

The guy should be a politician, never clearly answered anything

When I bought my Cummins I didn't plan on spending another 10 to 15 grand just to make sure it runs reliably. So I didn't and it has never let me down since day one.

Best Diesel engine is the one that has been maintained well.

Haha love how he keeps hinting to do an emissions delete

I own a 2002 F250 7.3 and despite its age, it has withstood the test of time pretty well and it's approaching 300,000 miles.

Really enjoyed this video..i just purchased my first diesel a 2015 f350 DRW to pull a 5th wheel and go travel the country so it's reassuring to hear someone with much much more knowledge than me comment on these engines...thanks!

Im a mechanic in a small town. People drive alot of old vehicles here, alot more than in any larger citys, yet it seems that most of the vehicles that come into the shop for diagnosis are the newer vehicles. I think it's because people are fixing the old vehicles themselves but can't diagnose problems with the new ones. New vehicles are more complicated, and there are so many different systems that can fail fail in a new car.

I have 3 1991 first generation dodges with Cummins 5.9L engines all have over 300.000 miles one just hit 400.000, no engine problems ever, new ford 6.4L blew up at 126.000, they want 12grand to replace, im going to just keep the old dodges going.

This video just steered me away from buying my first diesel. My camper is only 4000 lb anyway. Rented a Dodge 2500 with the Cummins, and it didn't even know the camper was back there. Wow

I am grateful for the 6.0 Ford diesel. After being towed in 3 times, I got fed up and bought a Silverado Duramax, best truck purchase I ever made.

I purchased a new 99 Dodge 2500 4x4 and kept it stock, traded at 251k miles while running great. Replaced it with a 2004 3500 4x4 with HO cummins, geared 410. The 2004 has been a beast, stock except K&N filter in factory filter box. Just tripped 205k miles and still a very reliable truck. I have looked at the new Dodge 3500, like all the new options similar to what my new Tahoe LTZ has but hesitant with the exhaust choking and DEF crap. Paying $80k for a truck, I would like to feel comfortable with it being broken in at 100k miles, not worn out.

Awesome video friend! I have a stock 93' 12v Cummins, maintained regularly and is almost to 400,000 miles. still running strong.

One of your best videos yet! Refreshing to hear simple explanations from a well spoken reserved guy when compared to many of the "diesel guys" out there on KZfaq these days. Keep up the good work!

Great video! You should do a segment with this guy called "Ask the Diesel Doctor".

Thanks. Very helpful. Your knowledgable guest narrowed the data down to choices I may make.

I appreciate the information and his common sense in assessing where we are with diesels today. Gives a clear view so others can proceed with informed decisions. "SUBSCRIBED" Thank you!

I switched from Hemi Gas to 3.0 Diesels. Love them!!!

The best combination Cummins and Allison

Interesting interview. Still keeping my old slightly modded 7.3 truck. Spent a pile on her, she’s a low miler pretty minty and getting 17 mpg towing with a mild street tune. Best of all no payments. But...... they day will come to buy something new and I appreciate this input.

Reliable diesel went out the window with egr.

I have no idea what you guys talking about but....I approve of this video.

I appreciate your info. I do wish you would be more specific about what diesel truck you think is better for towing a fifth wheel, or in general for service life, maintenance, etc.

Thanks for the video. Very informative.

Very informative. Thanks to both you guys

Great video. Thank you.

Awesome Thank You Justin, wish you had the camera there so we could watch the tear down. I would love to see some of the work he’s done! Great Video and as Always, God Bless and Everyone have a Safe and Healthy Holiday!! Ps, built a F250 Lariat online nice. Do they come with all LED lights front and rear?

Bullet proof.... My new goal for my 2017 F250 power stroke! I might have to go ”off road only” ; ) ...Great vid, tuvm.

I definitely think it'd be a good idea to have him on for more interviews and questions and definitely would be awesome if he could have his own channel 2 and that has helped me clarify on when I purchase a new truck for me it will still be brand new I'll just worry about all that EPA crap but now I know what can go that far thank you

This guy was being so careful to not dog any particular motor and say that most any issue can be resolved. Of course you can fix the problems but is it worth the cost.

Love your videos man. Keep on keeping us informed

Very helpful, love the truck we have, she's getting old tho, 1997 F250, 7.3 diesel engine, debating about fixing her up...I don't go crazy for a lot of vehicles out there but I do with this truck, thank U, u have been extremely helpful!

Sounds like he a FORD man!

The thing they forget to mention is that the 7.3 is a legendary motor. You dont need to worry about head gaskets and stuff like that

98 12 valve. Still tow a 13000 lb 5th wheel. When a 6.0 powerstroke is 20 years old and never been in the shop I'll be really impressed then. Love the channel btw.

Justin worked on my 08 6.4 powerstoke and put it on the right track, never have had a problem with it, dam good mechanic

Another good video. I sold my 2014 f350 and got the 2017 f450. Same color as yours lol keep it up brother you’ll have 1 mil subs within a year!

i know its not a full size like they are talking about here but im loving my lwn 2.8 duramax.

Really good video with a lot of good information. I like this type of content. Product reviews are always fun but the interviews with really knowledgeable people is, for me, the most enjoyable type of video.

I know I'm late to the party but great video. Bring this guy back.

I'll stick with my 7.3 powerstroke

"Let's just say you had an offroad vehicle" LOL

awesome, would love to hear more, I'm in the market for a diesel truck, need a 1ton, 4x4, crew but was concerned about buying older an getting someone else's problem, can't afford a 60k truck.. info is golden, need more.

Nice video yet again, and great info from Justin. Just for kicks, as Justin said all the new trucks have "corks" on both ends, intake and exhaust, so what is the best way, if any, to increase engine/vehicle life and power while maintaining warranty and emissions requirements in strict California. I have the 2017 RAM 3500 with 6.7 Cummins & Aisin with 3.42 gearing out back. Truck is perfect as is with 18K miles on the clock. So, leave it alone, or do some minor upgrades such as an ECM tweak, intake, or exhaust mods?

Can you tell us exactly what we need to do to have a "maintained" engine? This seemed vague to me so I'm just wondering if you mean making sure you hit those milestones in the service manual or if there are extra things we should be doing. Thanks!

Good addition to your content. I'd be curious if there are any "insider secrets" for prolonging diesel engine life other than routine maintenance.

Old video but truth never dies LOL. Did you interview him any more since this 12/2017 video JD?? I am learning my way and stuff like this is valuable... thanks as always.

Great channel, lots of content

Question for justin, I have a 2017 f250, how concerned should I be with all this cp4 failure stuff going on? Also what's the best solution for avoid fuel system damage

How to bullet proof any vehicle. Swap to 12V Cummins with stock parts and tune. Should be able to see million miles. No problem I wish I could get a 2017 cab gutted with all my old 1992 manual equipment and 12V Cummins. Till then ill keep swapping my 12V 5 sp into random truck chassis.

97' 12v Cummins replaced the 6.oh in my 03' F350. Was a lot of work, but still so glad I did that.

200k on a 2006 Cummins with edge juice and exhaust. Stock cp3 and one injector replaced. Been used hard had water in fuel last time it was down and fixed and injector stuck issue. Hoffs and lots of new filters fixed that. Still going strong.

I have no problem admitting I know NOTHING about diesel engines.

Love your video's. And love the fact that you've been watching streetspeed717 also.

This guy is a world of knowledge. Would love to hear from him more on things he had seen that has come on and what was done. I have a gas engine is there anything similar to "Bulletproofing" a diesel for a gas engine on an F-150?

I have a 2000 f350 dually 7.3 powerstroke in mint condition with 130 k miles omg I love this truck.

Great video, you need too make three video's highlighting each of the big 3 diesel engines, he touched more on the Fords than he did the Dodge or Chevy.

You must pay to play, period. A diesel truck is no different than an expensive sports car or boat. The more it cost, the more it cost too fix. If you want reliability and no repair cost, buy a bicycle. Myself I'm a 23 year auto tech and service all makes. I drive 6.0 f350, and my wife a sequoia. Never had an issue with either. Maintaining your ride is everything. They're all great, and they most certainly all break.

thanks for the great informative video! my question is about the reference to a "fortified EGR" setup, what does that exactly mean? Also what's recommended and the priority of mods /fixes /upgrades to help make my daily driver more reliable? I bought a second hand 2016 Ram Ecodiesel @96,313 miles. Engine-wise, I've kept everything stock except for adding a Fass fuel filter/water separator w/sump pum ( no EGR delete, no flash, stock chip etc). My mechanic has said (street inspection) it looks like it was primarily highway driven. Again I appreciate the vid and any feedback!

Nice informative video. You have a new subi....thanks

To me I question whether having to remove the cab of a pickup truck in order to work on an engine is bad engineering or not? The only real benefit is the extra space to work around the engine which is a plus for sure. I just wish they had quick-release fasteners and connectors to save work time and cost.

I like the part; take the cab off just to work onthe engine.. lol.

Great information!!!!

My neighbor is a Duramax man. He decided to buy a 6.0 Powerstroke for his business. He got it really cheap. Previous owner did a lot of the fixes to it. It’s been a very good and reliable vehicle for him. He’s been trying to buy my LBZ off me. I bought it and trusted it was a good pickup. Month after purchase had to put injectors in it. A costly item but since it’s been little stuff I’ve fixed.

The government ruined the Diesel engine! I’ll never buy another diesel that requires DEF

I’ll keep my 1st gen 12 valve

I Really Love The RAM 3500 Dually, Silverado 3500 Dually And The F350/F450 Dually. The Colors Are Very Beautiful.

i have a 2011 Chevy 2500 Diesel LML - i have had to replace the DEF tank twice since 2011 - 165,000 miles. No other issues.

Like he said. Not a trouble shooter. He’s a performance mechanic. If you want a real review on how reliable these engines are. You need to interview a master mechanic that’s not into performance upgrades. Nothing wrong with adding performance. In most cases that mean removing the smog parts. That alone will make it run better and be more reliable. But in most states that’s illegal.

I wish someone would do a reviews on the Ram manual transmission trucks.

Excellent intel here I subbed, I have owned several diesels including jap and german diesels, Im always stoked when they start haha but over the years I have learned a bit, def not an expert or even high knowledgeable about them. I don't like the Chevy diesels just cuz everyone I have ever used was a dog and had been dogged (almost all military ones) Ive had 3 -7.3 power strokes all bought used with high miles and questionable maintenance and all gone now. I do have one sitting in my yard its a 97 4wd ambu that had been rat chewed a buddy of mine bought, we got it running and man it just purs. My DD is a 89 f250 non turbo IDI I love it cuz of the simplicity and its got low miles and I have learned to enjoy working on it. I also have an old Mercedes diesel 4 banger oil burner, it aint no truck but dang is it reliable as long as you do the maintenance. Ive also had a Landcruiser with a diesel in it that was dead ass reliable and never failed me till the body rotted away. I just like to keep all my stuff rolling and diesels take a bit of effort and additives but there is something about a diesel running that is just....well you probably get it.

Great video!

Thanks Justin for your expertise! I have a question about my 2016 6.7 Cummins: I have been selectively waiting to remove my EGR/DPF on my truck due to having an extended warranty for 100,000 miles. I know these engines tend to be reliable, but would it be in my best interest to remove these things as soon as possible, or is it generally pretty safe still at 100K (current mileage right around 35K)? You seem to be a wealth of knowledge and I'd appreciate and trust your input. Thank you.

Interesting but perhaps one of the least informative and most subjective videos you’ve done so far. Ford 6.0’s have had massive issues with the EGR failures and stiction issues you shouldn’t have to heavily modify vehicle just to fundamentally make it work correctly, that’s baloney & bad engineering.

I have a 07 6.0 with 352K on it- I have replaced the turbo/egr delete/ oil rail replaced and injectors/ and it runs very well- It was a fleet truck before I got it and the only major repair it had before me was egr replaced (oem)

This was a great help for me. Are there any aftermarket additions that improve performance, the longevity of a diesel motor that your guest recommends?

A factory truck shouldn't need "modifications" or "fixes" as he said to make it reliable. $6500 to make a Ford reliable? Seriously? That's the problem with Ford 6.0 and 6.4. They're junk from the factory. Call it what it is. Then the comment that you could buy a 6.0 truck for 12,000 and add the $6500 "I've still probably saved vs. a Cummins or Duramax." Hilarious rationalizing buying a junk Ford 6.0.

7.3 that's all that needs to be said! The End!

Stepping outside the setups put in pickups, Cummins' ISX15 (often put in semis) is giving us quite a few problems in regard to coolant getting into the fuel system around the the injector cups, as well as the whole truck overheating way too often (230+ F isn't that uncommon during the summer). They're strong, smooth running engines and we get relatively few aftertreatment problems, but they definitely have a few things working against them.

Great video

Awesome and informative vid! Question for Justin: I have a 2006 Dodge Ram with a 5.9 l high output Cummins that is completely stock from engine to transmission to exhaust. The truck itself has just over a hundred twelve thousand miles on it so I'm wondering what are some upgrades you would recommend at this point? As of now there have been no issues with the powertrain whatsoever. I am the original owner since I bought it in January of 2006.

Don’t ya love the “I have changed my oil 1 time” I know EVERYTHING about diesels LOL

17 f250 is my first diesel truck and I sure hope it stays reliable cause I have a good amount in it.

Question for Justin: What's your opinion of aftermarket diesel engines like the Black Mamba Power Stroke or the CPP Cummins?

Prior to common rail (CR), the injectors were cheap, accessible, simple. With CR, the solenoid activated injectors were placed under the valve covers and required rocker arm removal to access the them. And they are crazy expensive. Owning a diesel became more questionable. Then DEF came in. That's it! Keep away from diesels unless your use absolutely needs one!

Can you make a video about emissions and DEF on new trucks? Pros, cons of deleting etc?

Good info. And I don't even have a diesel. It's good correct info for any of us thinking of getting a diesel in the future need, instead of me just buying the trim level I like

I know dick about trucks and I'd give this dude my credit card and my truck and tell him to have fun. Seems like a very honest dude

Here's an idea for a potential video...maintenance for diesel vs gas...cost....things that need to be done...

There’s a guy named Bill Hewitt (powerstrokehelp.com) down in Atlanta and he pretty much bulletproofs 6.0 trucks for a living. He sells those things like hot cakes. Granted they’re in the upper 20’s in thousands of dollars but you know it’s damn good work to make the engines last and he offers a lifetime head gasket warranty. I love seeing his work.

I have a 05 Excursion 6.0 and have had it for over a year. I have over 157,000 miles on it. Haven’t had any issues at all. And I daily drive it.

Great video. I’m a diesel nube and looking for a tow vehicle. Thanks for all the info

Great video very interesting

I have a Ford 6.0 that has 294 Thousand miles with NO head studs done and towing about 65k of those miles. The so-called Experts of any trade is about 1 out of 20 really knowing how to do a quality repair fix or restoration because it's all they do and the details are always left out because they WANT to make money. The 6.0 in short, first shortcoming is coolant formulation and water pump. The coolant would clog the oil and coolant cooler and then take out the EGR cooler. Easy fix is 2 run new coolant with new formulation, replace oil and coolant cooler EGR cooler run a coolant filter never run a chip never touch the exhaust and do turbo maintenance which means take apart clean it and that's pretty much it other than a few other things. I'm a journeyman in 11 different trades in commercial and custom home building and I took the same approach when learning the 6 o Ford diesel use what experts tell you AS information only not fact. You see people preach information but have little knowledge. to gain knowledge you need to study it, what ever it is. I'm 51 years old and in my experience humans will lead you right off a cliff, take your money and say you don't know I do.....lol.... so going backwards you would say to any expert how do I get 300,000 miles plus out of a 6 L diesel and not go through the cost of replacing head studs and I want a tote a 12000 lb trailer around a quarter of the time. Then see how many would say yes you can do it under $1,500... then you will see EXACTLY WHAT I MEAN...... good luck, listen to No One and challenge everything

“Imagine how it runs without those corks in both ends”! Lol.

Can you please do another interview with him? Basically update of this now that it has been 3 years.

Love your content just to bad it took 12 mins to get to the point. Would like for some one to do an actual comparison between all them in the 2017/2018 models not the 2011 , 2012 etc. been a Ford owner all my life but seriously looking at the gmc 3500. At times it seems like only main difference is what’s in the cab.

Duramax.... Allison combo ... can't beat them you don't hear much about them because they have least trouble then any of them...

I have a 2002 ram 2500 5.9 it's still going strong getting ready to do a overhead u should every 2-3 years it like about $125.

Hey Justin, I'm wondering what in your opinion is a great first time diesel truck to own. I've been looking at the ram 1500 eco diesel as a idea, but some of them had complete engine failure within 50k miles. What's your take on them as well?
