6.4L vs 6.7L Powerstroke: Which One is Better?

Overall, both engines have a lot of potential when modified correctly, however, the 6.4L is plagued with various issues that can lead to catastrophic failure. At the end of the day, the 6.4L is one of the most diesel engines ever used in a modern diesel truck, solely because it’s a pain to work on and its really designed as a throwaway engine.
The 6.7 was designed in-house by Ford since they got sick of all the issues caused by Navistar’s design choices on the 6.0L and the 6.4L. I think it’s pretty safe to say the 6.7L is undoubtably better than 6.4L in almost every way. It makes more power in stock form, it’s more efficient, its lighter, its quieter, and its way more reliable.

Doesnt like 95% of 6.7 powerstroke repairs you have pull cab as well as 6.4 powerstroke sure seen quite of few with there cab off in diesel shop
The tow truck i used to drive had a 6.4 that thing was a real power house. It was impressive. The tow truck was also on the third engine when I was driving it
Yea they rip used to drive f450 for the army
6.4 was a great engine til people started doing deletes.
@@ineedapharmists what people do deletes to stop them from blowing up.
255k on my bought new 6.4
@ineedapharmists they blew up either from the emissions system or from people putting those 250hp tunes on there stock deleted trucks. The compounds make like 60psi of boost without any mods to them
Once deleted and studs installed the 6.4 was a monster with the tunes available during its time. Innovative offered a tune that was good for nearly 350HP over stock on tune alone. I would see 58 PSI of boost. No tuned diesel since has impressed me as the 6.4. Most of course is due to not being able to delete plus tune due to our wonderful EPA. I'm truly glad I got to experience such raw torque before the EPA crashed and burned deleting diesels. No fuel additives or regen. 0-80 mph it was quite a ride. Miss that truck. I had a 2008 F250 FX4.
Deleted its got the best sound out all the diesel engines ford has used.
Hey, Im a former International tech, the 6.4 was a dumpster fire of an engine, and im pretty sure the "engineers" that designed it were huffing the fumes that came off it.
Honestly the Maxxforce DT that international designed are much much better with all the emissions stuff removed.
@@charlesrodriguez7984 or you could buy a non emissions dt lol they're everywhere.
@@Dexter_Solid that too.
I have both the 6.0 and 6.4 fords, really love my trucks no issues at all. The only very minor issues on both is just that one has gone through 4 engines and the the other through 6. Still running good and love the power!
Doesn’t sound minor....either get a 7.3 or upgrade to a 6.7 Cummins,power stroke, or duramax all will do you justice
GGS 899 I like how y’all defend actual trash. Coulda bought a Cummins with that money spent
Reefy M 7.3 trash?
Jaime Garcia 7.3 is the only good power stroke everything else is garbage.
Reefy M 6.0s can be good and from what I’ve seen the 6.7s are good as well, anywase among ford and dodge 6.7s they both have the same problems with the turbo failures
6.7 power stroke is better overall engine. But When it comes to raw tuning power before blowing up 6.4 is more powerful
I have a 08 6.4 got it deleted at 200k it has been a good truck always gets the job done and keeps on going.
What is the current mileage, and what other modifications did you make?
@@josephdepre4513 DPF n EGR delete. Running a single turbo and a Bully Dog tuner. It's my work truck got 255k miles on dash currently. Jus upgraded the fan clutch and radiator. Runs like a champ. 💯
6.4 owner with no problems ever. Depends who owns it and takes care of it people. Everyone has their opinion, so does this guy making the video, but any engine is shit if you do not properly maintain it. Like I said, my 2010 is still going strong to this day with over 400,000 miles on her.
514×××
All deleted never touched anything except oil change every 4xxx fuel filters ever 8xxx
Same here mines been tuned for majority of its life and is a straight power house compared to a tuned 6.7. 200k on her so far
What tuning do you use on you're 6.4?
@@smiller3110 I have an old School DashDAQ-XL running spartan tunes. I daily on the 150HP and 210HP sometimes 250. If I just wanted a stock truck I'd definitely go with a 6.7 for ease of serviceability compared to 6.4 but I just love the power and roasting other tuned trucks. I have a single cab and love it. I had a R35 GTR and loved driving my truck more and eventually sold the GTR.
Why are you so underrated i love your vids man keep it up
I loved my 2010 f350 Harley Davidson... until I cracked a piston using h s tuning lol
Hs is notoriously bad I don't even think there in business anymore that sucks
@@stillsmokntrees even worse was that I wasted 30grand Canadian to rebuild it. Not only did it take 5 months, but it would blow coolant at wot!! Even after ARP studs and gasketed heads. I think the shop fucked up by not replacing all the sensors. Something got fucked up in the computer somewhere and overboosted the new motor. Idk for sure what was wrong though. I had to trade it in before I lost what was left of my sanity...
Did u delete
Aaron Fisher yep 5 inch straight pipe from the turbo back
I have a 08 f350 6.4 fun as hell to drive a time bomb im sure but fun anyway
I loved my 6.4 powerstroke it was custom tuned running a mild tune i kept up on all the maitnence, it was a great truck loved the power, never gave me a problem, other than i replaced the radiator. But i dumped it for a 16 6.7 platinum before it was gonna set my bank acct. back sooner or later it was gonna get me. I love this 6.7 damn the power i of course deleted with ezlink, tyrant tunes, mpd sxe364 non vgt and beefed up the trans with a midwest. I can't leave nothing alone lol
Can you send me some vids with that turbo setup lol
6.7 by far
6.4 is just a punched out 6.0 with common rail system, same head bolt issues from the 6.0, just takes more power to find out about it, but the fuel system is capable of flowing so much it can easily destroy itself, so 6.7 is the only choice in this comparison
A built 6.4 with the main issues addressed is honestly one of the wildest power plants every out in a pickup.
Same head bolt issues? No. Watch ol Bill at Powerstroke help. He'll show you the bolt comparisons. No. Pistons and the exhaust systems cause the failures on 6.4s. Mainly from regens. With a full delete and piston change can certainly take care of the issue. 6.0 and 6.4 are apples and oranges. Not the same.
6.4 has a bad cam shaft, paper strength push rods, rockers are junk. When you go rebuild it almost every 6.4 builder sells kits and push hard for you to take their stage 2 kit that have all that fixed.
@@codyparker679 the 6.4 is nothing like the 6.0. the 6.0 it's easy to address the faults. The 6.4 is just plain disposable. You can bulletproof a 6.0, but you can't bulletproof a 6.4
Max force 7 pistons solve and a custom tune fix a lot. I don’t see the head gasket issue nearly as problematic on the 6.4 despite 14 vs 16mm and a revised cylinder head compared to early 6.0
There’s so many people here who are gonna disagree with me on this but the 6.4L powerstroke is the only ford engine I’ve actually had good luck with. Also the 2 valve 330 is another one I like and everybody else hates both.
You forgot to mention that the 2011-2014 6.7 Powerstroke is very famous for the crankshaft breaking even under stock power because they don't have a bedpan setup.
2020 F-350 w/6.7. The torque along with the 10 speed was an amazing improvement with industry leading 0 to 60 times in a truck that scales at 8100lbs. And no mistake about the ability to pull loads with 475 hp and 1050 fpt. You see very little difference between pulling 10,000lbs vs the full 21,000lbs.
I always find these reviews years after buying the crap that was supposed to be an upgrade from the crap that preceded.
2008 6.4L f350, 216k miles, still running. Looking at 2020 models now.
Just bought a 2008 I like the truck but I'm only getting 8.8 miles per gallon pulling a 21 foot enclosed trailer can I do anything better to get better mileage
@@light784brick9 No. There is nothing that can be done about that. They simply get crappy mileage.
I loved my truck too but the 6.4 is a throw away motor that costs about 20k to replace.
I'm good with my 08 6.4, best truck iv ever driven. Did have to delete egr and dpf which wasn't difficult even for a rookie mechanic like me Thnx to tech ron, powerstroke bald dude, and the military dude on injectors . Help videos are awesome.
Pistons still crack
Funny the question is even being asked..its a no brainer here.
How is this a video
LB for LB a 6.4L will embarrass a 6.7L any day that ends in Y. I'm here because I traded in my 6.4L three days ago on a 6.7. That being said, both are beautiful but a 6.7 cannot touch an equivalent 6.4L in power application. It just does not have the balls or the ass to drive it home. Great video man, I learned quite a few things that i did not have in my extensive knowledge of the 6.4L.
David Adams until it lets go on a cross country trip towing lmao. What’s the point of owning an unreliable truck with more power that can’t tow a load long distance?
The 6.7 can easily match the 6.4 in power. What are you even talking about?
@@austinr09 whatever you say. I said pound for pound. Equivalent. It can not be done.
austinr09 lol you dumb?
2008 6.4 514xxx miles hotshot truck oil every 4xxx fuel filters ever 8xxx
No. The WORST diesel in automotive history was the GM 350 diesel. The 6.4 might be the worst engine put in a Ford, but the GM 350 holds the title for being the worst.
I'm pretty sure those old enough to remember will wholeheartedly agree with you on that, hands down. In fact, it can be argued that that was easily GM's biggest monumental failure of the late '70s and early to mid '80s. It is also probably what leaves a bad taste in everyone's mouth about anything with a diesel being released by GM. Literally everything from lacking a water separator, to weak head gaskets to failing injection pumps and the list goes on plagued that engine. I remembered many of the cars equipped with that engine being sent to the scrapyard very early in it's life due their failures and maybe a few extending their life not by much with hack job gas engine transplants.
I’m no expert but didn’t they just take a regular gas 350 and jerry rig it to run on diesel
6.2 and 6.5 GM diesels were gutless turds, in a HMMWV are utterly useless.
I’m not old enough to know. I knew the the earlier GM diesels were gutless, but that’s about it.
@@Dustrunnersauto The 6.5 GM turbo diesel had about 190hp and 390lb/ft. In a 5500lb non armored HMMWV it wasn't terrible, but any of the heavier variants (up to 12,500 in FRAG 6 armored) they were garbage
You forgot about the fuel pump system it's a common-rail. With that in the turbo that's what makes the 6.4 be able to do 300 extra horsepower with just a tuner exhaust and cold air intake
I have owned 7- 7.3L, 1- 6.4L, and 1- 6.7L . As far as which one is the better built motor it's hands down the 7.3L . 334k on the current one with several mods and 410hp. Which one has been the most costly to operate, definitely the 6.7L. It's a nice quiet pulling platform but has already had one catastrophic CP4 failure that has really turned me sour on this truck. Lastly my 6.4L KR is a beast of a truck. Crazy fast and pulls like a train. It had 248k on it when the valve train imploded and wiped the motor. Full UCF machine shop rebuild and ringed heads top it off. All that said the 7.3 has been maintenance items that I turned into upgrades. The 6.7 has me disgusted. The 6.4 is all smiles per mile.
I love my 2019 6.7 Powerstroke!
You must never heard of the 6.5 Chevy diesel 😂😂😂. Those things were ticking time bombs 😂😂😂
Um no. 6.5 is an excellent diesel engine. What crack are you smoking?
Those were good engines. The Oldsmobile 5,7L diesel that GM put in their trucks was almost as bad as a 6.0
MGGW Mcadams 5.7 was by far worse that the 6.0.
@@deadlydavem heads aside the 6.0 is a fantastic motor. Every mechanic I've ever talked to said if they had put more time into the 6.0 then it would've been better than the 7.3
Dude the 6.5 is the official motor of the Humvee, their not powerful but their great workhorses.
Love my 6.4,don't beat the shit out of it every time it's driven,don't put a ridiculous tune on a basically a stock engine and the damn thing will be fine,it's simple
Same here. My 2010 has 290,000 miles on it. Starts every day. I think this guy’s position is that any engine that fails when you attempt to double the horsepower and torque Is a “junk engine”.
Amen good word all very true
Just drove a 2012 F550 6.7L to 200K, flawless reliability. Only real issue was broken exhaust bolts at 180K.
The truck I drive weighs 20,000 lbs so Always working hard.
Engine starts and runs like a champ.
There are more positives to the 6.7L design such as its steel pistons introduced in 2020. Steel is used in race engines - stronger and handles more heat and pressure the aluminum pistons. The 6.7 is a good engine that gets revised and updated from time to time making it a viable alternative to the Duramax and Cummins. My ‘02 Duramax had only 300/520 TQ. It’s amazing how torque and HP have increased significantly in these new designs.
I can’t lie. I love my 6.4. But I’m careful with it. I don’t hotrod my truck at all.
ya, fkbois hotrod their shit doing burnout videos and then complain when the engine blows.
that aint the engine, its their dumbass.
You have every right to take cair of you 6.4 because people who don’t own one pamper the ram and Chevy,I love our 6.4
I had a 6.0 liter F.O.R.D., if I pulled a trailer, the 4 bolts around each cylinder ( should be SIX) would allow the head gaskets to leak. This put 2,000 psi power pluses into the coolant. The radiator cap would TRY to release the over pressure ( 16 psi cap). That pressure would go to the plastic bottle and blow antifreeze on the window & the cars windows around me.
Called a tow truck to haul to Ford dealer (still under warranty) the FORD tech. said everything is fine. No problem.
Ford refused to replace headgaskets. The next day, towing a trailer, the coolant pressured up and exploded the E.G.R. cooler. This time I did NOT call a tow truck. I drove the P.O.S. home. The NEXT day I bought a CUMMINS, that now has over 500,000 miles. Change the oil, fuel filter, water, pump belts & rive for million miles.
The cab of Dodge has NEVER been off the chassis.
CUMMINS.
The cummins is a better motor than the milkshake maker, but the truck around the cummins is absolutely garbage imo
@@stanleykendziorski7964
Remember was F.O.R.D. would NOT use the. P.O.S. 6.0 liter on the F-650 & F-750.
F.O.R.D. knew the CUMMINS WAS BETTER, installed the CUMMINS in the F-650 & F-750.
@@stanleykendziorski7964
I would rather have a ford cab.
But the Dodge cab is holding up very well.
@@nellyfarnsworth7381 the cummins is also used in many medium duty applications.. the international version of the 6.0, the Vt365 had a lot less problems than the powerstroke versions did.. still the same flaws, one of which can be changed with head studs.. ford upped the horsepower from the international version..
Cummins have their problems too, especially in medium duty applications, but all the light duty truck motors in a medium duty application does.. the kodiak trucks had a lot of problems with the duramax engines, but not with the cat 3116/3126 so much.. motors designed for medium duty applications are gonna do better than the light duty truck motors
@@stanleykendziorski7964
I have driven then ALL, CUMMINS is BEST.
Yes CUMMINS beats CAT.
I want to see a video about the 6.9/7.3 IDI vs the 7.3 Powerstroke.
Me too
Just fyi. Most modern common rail diesels will fuck up if there is water in the fuel. That's why most diesels have a water-fuel separator
All I hear about the 6.4 is how bad they are. But those Harley Davidson editions are beautiful... worth it?
Fummins it!
Either bulletproof it or like that guy said lol
Okay now circle back around to the start.
7.3 vs 6.7: which one is better?
I'd honestly like to see that one
@Cody Gatzke 7.3 40 pounds of boost on stock head gaskets
6.7 by a mile.
200 more hp and 500 more lb ft of torque...
No comparison.
7.3. A lot way better
@@tonymars6003 lol. “A lot way better” anchor...
6.7 has been in production for 11 years... that kinda says it all.
Update on the 6.7L Powerstroke’s output numbers
HP: 390-475 (500 H.O.)
TQ: 735-1,050 (1,200 H.O.)
"One of the worst diesel engines in automotive history"
Yes.
My first Ford was a 2010 6.4. I bought it already deleted and it might be the fastest thing I’ve ever been in. I now have a 14 6.7 and I’m deleting it this weekend. As of now I’m going with a bigger turbine wheel but will that turbo off a 6. 4 for on a 6.7?
Found a 6.4 for a great price! Guy told me the water pump replaced and drain and fill on coolant, both fuel filters replaced and the fuel water separator bowl took apart cleaned, and reinstalled. The truck is all stock and has 248k miles. The truck is nice except for a ding here and a scratch there and a hole in the driver's seat. It's a lariat to. Really uncertain. Any advice
I hope you didn't buy it
@@Darkwarrior1298, I didn't. Ended up buying a built 6.0 powerstroke
@@Kirsch6.7 how's the 6.0 treated you?
Client of mine owns a 6.7 cummins soon be 800k miles same motor since new ,fixed some oil leaks . We put in 3 transmissions so far trough out the life of the truck. Towing over 30K equipment to Job sites all around the state with a tunner. All it takes to keep these trucks go, is to maintain them and be smart about the tune. Too hot and it will burn your wallet.
The 6.7 is the modern version of the 7.3. My buddy has a SXE 364.5 Non VGT turbo on his 2014 6.7 and it honestly sounds like a 7.3l.
Just because an engine "sounds" like another engine doesnt mean it's like that engine. The only 2 similarities between the 6.7 and 7.3 is the fact they're V8 4 stroke diesel engines. That's it
I've always known the 6.4 power to have sequential turbos not compounds. They work in sequence 1 goes and than the other
It’s been quite a while since I looked into this, but if I remember correctly they are sequential but since they’re a single unit, it’s referred to as a compound setup.
i really need some advice from someone that really knows i have a chance to buy a 6.4 at a ok price but i need it to haul stuff from coast to coast with 144 thousand miles and its pretty much my only option, but i cant afford to just buy a truck if its not gonna do what i need?
Subbed because informative, simple, a solid presentation, and you speak clearly and it's just overall a good quality video. Watched a couple other of your videos too.
I don't even like diesels, or trucks for that matter. 😂😅, Guess that shows your videos are rather capturing.
My 08 6.4 has 300000 on it is still the fastest truck ive owned full delete mild tune but is a money pit 6.7 on next one
99% of theses people don’t have there 6.4 deleted we have 2 6.4 truck both deleted and would walk a 6.7 any day of the week
Phu Doan we have owned a 6.7 powerstroke and it wouldn’t hold a candle to a 6.4
mine has 205000 miles deleted.change all injector lpfp and hpfp.run good.
My 6.4 has 150k and I'm getting scared cause I just got it as a graduation gift and it's fully deleted and mini maxx tuned and I don't beat on it but watching all these things get me worried
@@jrduarte2509 if its deleted u should be fine only thing u may have to change in the future is the injectors at 200000 and filter housing cause the regulator in the stand pipe gets weak.
Everyone commenting how the 6.7 is not as efficient, you do realize regenning kills mpgs. Deleted 6.7s can get up to 25mpg highway depending on the rear end ratio
Its 2023 and im still driving mý stock and Deleted 6.4. But i just did a rebuild on the tranie. and shes ready for another round ❤🎉
The 6.4 if you delete emissions and maintained them correctly and didn’t tune them heavy where dependable they just where horrible on fuel economy the 6.7 is great on fuel with the same power of the 6.4 and less maintenance issues if you want to delete emissions and hold up better with high tunes due to the torqshift 6 speed from 2012 and up that literally is the f750 commercial truck transmission.... I’ve had Cummins duramax and powerstrokes the new ones are all tit for tat but the more refined one nowdays is the ford as far as good all the way around on power fuel efficiency power distribution/ turbo lag ...cab and chassis/suspension quality
Efficiency is Cummins all day. Inline 6 with low end torque is going to be more efficient at burning diesel than any v8 with high end torque could.
The Puppet Of Everything if there front suspension was a lil stronger and there transmission was better , and if I planned on tuning and deleting the emissions right away then yeah the new 6.7 Cummins have way to many issues with the emissions and it makes them very weak compared to the competition and the fuel economy wasn’t any better in my experience I’d say maybe within a single mpg are within margin of era ...
Also as far as lasting forever no body is buying these trucks to last for 20 years nowdays you will trade it in if your buying a $80k truck you most likely will be able to afford to get a new one and if not the 6.7 power stroke right now on fleets locally are at 375.000 and nothing significantly replaced mechanically, same as the duramax work trucks and the Cummins all the new trucks last If not abused
Had a 2008 6.4 , pulled like freightrain ! Always something wrong with it !!!!! Caught fire and burnt about a month ago , total loss ! My first and last diesel truck ! Replaced with a V 10 , my second V10 .

@@dustinmcintosh6799 explain?
It all comes down to the quality of their engineering department....a.k.a how much they pay their engineers. Ford crushes International on that one. Cummins is first class organization as well and their products reflect that. I do own a 7.3, but what have you done since then international?
I think that the 6.7 is a very good engine when you remove the emission systeem and use good diesel it really dosnt have an issue with the engine itself
My 6.4 has 319,000 miles. It was deleted when new and a tuner installed. Incredible power, empty just boils the dual rear tires and buries the boost guage. Of course I put all the factory emissions equipment back on it since I've owned it! Transmission at 278K only problem.
Cab off repairs are common between ford ram and gm
I've got an 08 (Job 1) 6.4 which is completely stock and has always had all scheduled maintenance/service done religiously. Yet it still has been plagued with problems, all being engine related.
Leaking radiator (replaced), leaking head gasket causing over-pressurizing of coolant system (cab removal repair), oil leak at bedplate (cab removal & engine removal repair), HP fuel pump failure (cab removal replacement), exhaust temp sensor failed (1 failed but replaced all 3) including a new DPF, exhaust temp sensor failed on up pipe (replaced). All instances, except radiator and oil leak, took several trips to dealership service dept. in order to diagnose because no codes were initially stored and it only gave us problems when under load while towing our RV. At these times we would experience reduced power (limp mode) and/or blowing white smoke, both of which would temporarily go away after doing a shutoff/restart. Fortunately all covered under extended Premium Care warranty, which I've renewed twice because of trucks history, at $3200 a pop. Switching to a 2021 6.7 when current warranty expires the end of next year. The 6.4 was a disaster as was the 6.0. Ford Motor Company did the right thing by ending their relationship with Navistar. So far,, I have heard/read nothing but positives about the 6.7 since its rollout in 2011, both privately owned and with fleet trucks.
Crittergitter 10 lol are you seriously implying that just because it has “regular maintenance” (which is a lie) means it’ll last? Using the wrong oil filter in any Navistar is certain death for the engine. Quality maintenance is needed. I serviced 6.4 fleets when I worked for Ford and they never had any major issues ever. 500k+ bone stock. I daily drive one and never would buy anything else.
Literally all of the problems with the 6.4 can be traced back to the ridiculous emissions equipment. Delete the emissions from the 6.4, change the fluids and filters regularly, and it can be just as reliable as any other powerstroke. That said, when mine blows up a 5.9 Cummins will go in.
Yeah yeah know a cousin's wife's boyfriend's uncle that has one with 72663626 miles on it all original oil changes every .016374 miles runs like new. You just gotta take care of them they're good trucks!
@@RiggyRonnie Does your cousin know his wife has a boyfriend? Ouch. BTW, one of my best friends uses a 6.4 for farming and has over 280K miles on it. Deleted and it pulls like a freight train hauling equipment trailers around. No problems other than a new radiator.
Thats just a bandaid. How can the 6.7 cummins be very reliable with all the emissions. Bad engine. Bad design. Super expensive repairs. Cab off.. etc. I can go on forever.
@@RiggyRonnie Wow what a machine: that's 4,437,744,350.800049 oil changes, hardly unreasonable. jk, my 6.4 made 750+ hp and was awesome for the last 6 months of its life till I lost 3rd gear and 1 turbo, and I knew a fuel system rebuild was looming, luckily I got $11k out of it for trade in in FL even with DPF and custom tune at a Ford dealer...
Damn a Fumblins. My heavy equipment mechanic did the Fumblins swap at the same time as my 6.4 was at UCF machine shop being rebuilt. His reasoning was that he had a 5.9 on his shop floor for free. We spent equal $$$. I saw the tears in his eyes when I took him for a ride afterwards. 😅
Too bad they couldnt incorperate the 6.4 turbo n pistons into the 6.7..... I wonder if it would work?
Lmao I fucking love my 6.4

Same here
6.0 was way better on fuel than any of the other engines we got a 6.7 at work and it's a diesel hog under load my 6.0 under load does way better I get like 14mpg 240,000 miles and only thing to fail was high pressure oil pump and that was fixed with basic hand tools
I'd love to see a review video on gm 6.2l diesel vs 6.5L diesel
Good Video man, Do both usesame trans and is a change out possible without computer, ecm, you know what I'm getting at. I love this truck so in your mind is it worth it.
thanks I'm Jake at Jakes Auto rebuild
Only problem with the 6.7 is that darn cp4 fuel pump. Other than that great motor
You don’t like the CP4 pump?
Cough "Maxxforce" Cough
The 6.4 powerstroke. The most expensive throw away engine ever built.
Great video very Informative
So the Pistons are the weak point of the 64. And rich fuel mixture which leads to heavy sludge sounds correctable.
@Salinas photography For the rollers in this void
Awesome stuff. I have a 2015 F250, 6.7. No mods except S&B cold air , and 5" DPF back exhaust.
For "emission compliant"?
Those simple mods made the performance bump up noticeably. I usually drive a Pete with a C-15.
Diesel rules.
The 6.7 could be far better than what it is and I’m surprised Ford didn’t build it much better than what it is…I have many acquaintances who flat out blew their 6.7’s up and they were stock engines covered under warranty…they also put this engine in their medium duty 650-750 lineup and I’m sorry but that engine has no business being in a medium duty truck!!..Ford needs to remember they are in competition with one of the largest and best known for reliability diesel engine builders in the world and they need to act accordingly to that fact!..
7.3 and 6.7 engines are the best
Yep. If ford didn’t sell the 6.0 and 6.4 the PowerStroke would be a much better name and ford would sell even more trucks

Good video bro!!!
What is a good tune for the 6.4 engine?
SCT custom tunes
No discussion of unkeyed bearings? Big problem on the cab-chassis 6.7's I've heard. Correct spelling 'Bosch'. Description missing a word before 'most' above... the 'most' what?
Can you make a video about the Honda 1.5T L15B7 I have a 8th Gen Si debating on switching out these new engine design
My 6.4 powerstroke is the best truck, have a cold intake with a tunner and 250,000 miles, no issues..
How about a non bias comparison between the power stroke and a duramax.
Even I think both those engines are great in the 1980 to 2011 Ford Crown Victoria's and Police Interceptors all the time.
This explained it from top to bottom. I've been looking at 6.0, 6.4 and 6.7 powered trucks and was really curious why 6.4 trucks are next to nothing and yet have great history with them. I knew the 6.4 sucked but what clued me in on how bad was when PowerstrokeHelp straight up told people who buy them to stay the hell away because if you're dumb enough to buy them, you're dumb enough to get stuck with them. But this went into a lot more detail.
Yeah I type in 6.4 on Facebook market and like 30% are parts trucks lol
@@RiggyRonnie I got that impression too. I haven't looked much on FB, but I have kept my eyes out for dealers near me. I'm just looking to get another diesel 3/4 ton. I had a 7.3 Cclb a few years ago and then got a 7.3 idi after that and I'm looking for something a little more modern without it being a pig like the 7.3.
Bill from powerstrokehelp literally said "for all you guys that considering doing a Cummins swap in a Ford. The 2008 to 2010 6.4 platform is the only one worth doing it on. My shop won't even touch a 6.4 anymore."
@@nahrens223 unless it’s a 30k motor job probably 💀
Wow thank you I needed this video 👍🏼👍🏼
There seems to be one key point missing here. Ford was responsible for the majority of the problems with the 6.4L Powerstroke. Ford was already planning their own engine, and the 6.4L was their experiment into making a diesel engine run. The 6.4L wasn't the last straw. The 6.0L was, and Navistar already knew it was at the end. The 7.3L and 6.0L Powerstrokes were essentially the same engines Navistar put in International trucks, just a different color of paint. Ford bought a cheapened version of the 6.4L longblock from Navistar. The turbochargers, fuel system, EGR, DOC, DPF, etc. were all Ford's own doing. I'm not saying that the 6.4L used in International trucks wasn't a piece of shit in its own right, but you can't blame Navistar for how bad it was in Ford trucks. Knowing Ford was soon to be gone, Navistar came up with the TerraStar truck, equivalent to the F450 and F550, in an effort to recover some of the market for their V8 engine as a justification for continuing to produce it. Obviously that worked well, given that the V8 is long gone, the Indianapolis Engine Plant and Indianapolis Casting Corporation have been leveled, and that class of International truck is now a rebadged Chevy.
The 6.L was a good engine but the only problem was the oil cooler the broke down and damp the water i your intake the 6.4 is same engine as the 6.0 the only difference in the top of the engine
Great job.
Not even a question to be asked if you know diesels. Don’t even need to watch this to find out lmao.
gotta make deletes to 6.4, and then its fine.
Basically fully bulletproof but at that point you should just get a 6.7 tbh
Not fine. Still have all of its designed in failure points.
@@turbolq4 I'm not arguing that its a commins or Toyota, just saying with care it can be ok.
Can you use the 6 4 turbo system on the 6.7????
I’m sure you can I’ve always thought of the same thing or even a 7.3 turbo but never seen anyone do it yet I wanna see someone put a Cummins in a 2020 350
This video is the very best CUMMINS commercial.
Chow Dong too bad the rest of the truck is fucking junk.
The 6.7 is actually a Hot V configuration
So that alone being said powdered metal connecting rods. Someone explain to me how a 6.4 is good for a 1000hp I’m assuming at the
Crank And a 7.3 connecting rods are good for 400 450 max. Let me know it an honest question
The only thing the 6.4 was good for is forcing Ford to get off their butts and design their own engine.. between the annoying issues of the 6.0 and the catastrophic issues of the 6.4.. the internal pressure for Ford to make the 6.7 rock solid must have been intense.
They " build " their own engine
As issues that plauged the 6L power-stroke really strained ford and Navistar's relationship when after the 6.4 power-stroke's production run ended had the pair end their relationship when ford took lessons from the three decades of engines built first by international harvester and later Navistar to develop an entirely new engine to meet current and future emissions standards when ford came out with the 6.7 power-stroke.
7.3 was the best , then the 6.7 for running stock (no bulletproof)
6.7 is better than 7.3 it’s way more reliable than the 7.3 don’t get wrong the 7.3 will last but it’s not more reliable than the 6.7 for shit
@@HSSANITO the engine itself is well built but I’ve had nothing but dpf problems with my 14 and my 17 is on its third turbo
@@raptordan6851 how do you go on your 3 turbo tho my dad has a company and I work for him and like the only problem we’ve ever had on one of his 6.7s was a turbo leak but we didn’t have to replace the turbo we just had to fix one of the pipes or whatever and the one I drive was just the DEF but once you take that off it’s gonna run good as new it’ll be able to breathe much better DEF is a regular problem that’s gonna happen to anyone wether you drive a durmax or Cummins you know but if you don’t get rid of that def it’s gonna mess up the engine more so that could be why you’re on your 3 turbo too
@@raptordan6851 and the 7.3s we’ve had have lasted forever too one of them is about to hit 500k miles the other 7.3s we sent to our ranch in Mexico with new tires and stuff those had around the same amount of miles and they’ve gone through beatings I’m talking about 20k pounds on a daily, and we’ve also used Cummins but the problem with them is the transmission even if you get a stick they’ll fuck up
@@HSSANITO I’m deleting my 14 f450 here in the next couple weeks , it’s still a solid truck , as for my 2017 f350 platinum the original turbo went at 10,000 miles full on limp mode. The last time was at 30,000 miles, one day just started barking with erratic boost and squealing, I’ve got 45,000 miles on it now and who knows how long it will last , I asked the local dealer if it was just my bad luck lol , dealer said they change them all the time primarily 16-18.
Just redo the 7.3 powersmoke. Old school 7.3 with a modern twist. No replacement for displacement
I love my 6.4 ,,it has an egr delete and a dpf delete,,tuned with mini maxx h&s,,I’m getting over 650hp and 1300tq,,Never had an issue,,207,427.4 miles,,how do I know,,cuz I’m in it now,,very dependable truck,,,
We meet again lol
@@locustvalleyfarms7241 lol 😂😂😂😂
Quick update,the 6.4 is almost at 208k miles,,and here’s the best part ,,,NO ISSUES 👌👌
My 6.7 goes through more fuel than my old 6.4..... just saying
Goes through more fuel and less responsive out of the gate.
Bc the 6.7 is actually running
@@imalittlecrazy626 lmao. 6.4 will never burn any fuel if you can't get it to run..
6.4 is disposable. Rods and wrist pins missing bushings. Built to save money. Take very good care of it and do not tune it and it will be okay. The engine is virtually non rebuildable once it goes. Yes they're exceptions but it's a disposable engine
Oh for the love of God. Not the Navìe•Star pronunciation. It's Nav•uh•star bruh...
YoU PrOnOuNcE iT WrOnG.
Its pronounced as they can't design good engines for ford
Wtf is a throw away engine dude? You talk up all its great features yet call it this? Explain?????
“Throw away engine”: an engine designed to last until the end of the power train warranty to limit warranty costs.
The 6.4 was designed to be a throw away engine and it wasn’t even a good throw away engine
hey there #DustRunnersAutomotiveJournal Love your videos , they are full of goood and reliable info, how about a video about steering, suspension , drivability and comfort. thnx again
I'm pretty sure Bosch does not have an e at the end
Great video bud.
oh….Bosch* =P
Will a 6.7 hook up in place of the 6.4 or not
nope
