The Truth About the 6.4L Powerstroke (And Why It's Not That Bad)

- I do want to mention that a lot of the issue we talked about in this video are caused by lack of proper maintenance. With perfect maintenance, a lot of these issues are kept at bay or atleast reduced in severity. Plus, a lot of the problems on this engine can actually be solved by simply deleting them. That being said, this engine is quite problematic and hard to work on, and it's easy to see why so many people call it a junk engine.

Can you a video on the jeep 2.0t Hurricane code name for it
I can definitely do that in the near future!
Rebuilt engine by J&K Engines. ARP studs, updated International style pistons, new cam. I now live out of the country, so deleted EGR and DPF. SCT X4 tuner with custom tunes. Runs excellent. More power than stock and runs very clean. 15 MPG on the highway unloaded.
@@Dustrunnersauto hey man thanks for the videos I appreciate it I watch it when I'm bored just fiinshed subscribing to you thank you
I have a 08 from new and within 2 weeks of getting it I removed everything emissions and it’s my everyday truck I love this truck the power is crazy and it’s has some miles on it I think it’s up to 400k and running like a champ 6.4 gets a bad wrap Thanks guys
I’m thinking about buying one. If i do the deletes you think it would end up being ok?
The pistons tend to crack around 260km. To fix that you have to rebuild it with a maxforce set. (I don't believe it's so much a Navistar problem but a "hot tune" issue.)
The problem with just deleting a high mileage 6.4 is that there has probably been damage to your front cover (water pump) due to the excessive heat during Regen cycles. Also main bearing damage from oil dilution due to the overfueling which occurs with that same Regen cycle.
yup I agree. I’m in the same boat. I use my truck for towing and hauling things and its got some good power for sure. did the same modifications to mine and runs great! even with the bad wrap cliche 😆
@@gavingifford2964 depending on what tuner you can get, then yes. A lot of engine issues people have after it’s been deleted, it’s from H&S tuners. I have an H&S xrt pro for my 2010. I’ve had it for 4 years, but looking at different tuners.
@@t.c.973 the main issue from the front cover is due to cavitation. I know of many trucks that aren’t deleted and have had that issue.
This video was actually a really good job at summarizing the common 6.4 problems. I bought a 2010 F350 powerstroke (crew cab, long bed, lariat 4x4) for $10k, had a hole in the block. I found a core block locally for $500, had been sitting outside in the mud. I rebuilt the block, with ceramic coated maxxforce pistons (better resistance to cracking), aluminum pan, kdd heads, bigger compound turbos (73/59), odawg manifold, new injectors and k16, arp studs, 6.0 exhaust manifolds, airdog 4g lift pump, patriot tuner, updated front cover, oil cooler (went through 3 oil coolers because they filled with sand) ,s&b cab mounts, spearco intercooler, rcd intercooler pipes, riff raff boots, no limit intake, full 5" mbrp exhaust, new ford rad, plus many other smaller components. This was over the course of 2 years, and costed me north of $40k for just the motor build. Originally used rebuilt stock heads, but had problems with them, so went with kdd o-ringed heads. I have my own 2 post lift, so cab comes off if there is any trouble. Built 6.4's are pretty special, they come with factory VGT compounds, so they spool instantly and produce insane amounts of torque at low RPM. With larger frame compounds (that are drop in turbo upgrades) and proper fueling you can make 600-700 HP, with zero turbo lag. I could have easily bought a used 6.7 for the price I paid, but in the end I am pretty happy. If you are interested in learning more about modifying 6.4's, check out the facebook group "08-10 Ford 6.4 Powerstroke", awesome resource
You should have bought a used 6.7
Bruh wtf tou should've just purchased a used 6.7
@@mailmeglueplease but 6.7's are slow
Damn man that’s a crazy long list you should post a link or UA-cam channel of the truck I wanna see it in action
What an idiot
Sooo basically, emission controls ruin everything they touch.
Absolutely
Not necessarily if it is designed decent enough
@jeremy pollitt I mean not really for gasoline engines, but for diesels If it isn’t designed good enough then it will cause problems yes
Even if deleted its still garbage
Yes
I have an 08 and I bought it with 135K miles on it. The first week I took possession I took it to a shop to have the EGR and DPF deleted, cold air intake installed, and I'm running an SCT tuner. I do regular maintenance on the truck and change oil every 5K miles and fuel filters every other oil change. I did have to replace the radiator once as they are plastic and known for cracking. Replaced alternator as it burnt up on me as well. I did notice a coolant leak around 195K miles and ended up doing a cab off maintenance to have new head gaskets done, surfaced/flattened the heads to make sure they were flat, and replaced factory head bolts with ARP studs. Mechanic recommended I change the rocker arm assemblies while I had the cab off and I did, but he said they actually looked okay but we changed them anyway. Also had the downpipe replaced. I had about $5K invested in this service as I had a local guy do the work who was a city fleet maintenance guy who works on the same engines daily. I have 255K miles on the truck now and it runs great and has tons of power and I haven't had any issues since. I don't run a high power tune and use it as a daily driver. Fuel economy is good with the deletes and better than most new trucks. All in all, for the 120K miles I've owned the truck, I don't feel like I've had to put too much money into the truck to keep it running well. Did I get lucky? Hard to say, but I think doing routine maintenance and deleting the emissions stuff is what has helped.
My 6.4 was deleted and had regularly maintained it had what some would consider high milage for a 6.4. One of my close friends has one still that was deleted and studded it currently has over 400k miles on it. Maintenance is everything.
I’d like to touch on the oil vapor issue. My truck will get an oil vapor and condensation buildup in the intercooler from time to time, the most noticeable symptoms are excessive blue smoke and hesitation on acceleration. There’s 2 easy solutions to this. 1. Pull the silicone boot off the lower pipe, between the intercooler and the up pipe to the intake manifold, and drain it. Kinda messy. 2. Work your engine. Something people tend to forget (or not realize) is the diesels in our pickups don’t get worked hard enough hauling air. They don’t get worked hard enough when racing. They run so much better when you hook them up to a trailer, and actually use it for what it was built for: hauling. I’ve owned equipment since I was a kid. They need get an honest load for extended duration! My truck runs the best after I’ve hauled 10-20k on the the gooseneck. It really doesn’t take many miles to notice a difference, either. If I’ve just been cruising my F350 for a while, and it starts running crappy, hooking up to the trailer with a tractor on the deck, even for only 10-20 miles will clean out the crud from the intake sufficiently to notice a much smoother, quieter engine after. So, don’t beat the hell out of your truck, ( but use it for real truck duties), maintain it to the “severe duty” schedule, and it’ll treat you well. Just my experiences from owning several tractors, and 6.5 Chevy diesel prior to my current 6.4 Ford. (I’ve had my 6.4 for 8 years now, it’s been a great workhorse for me.)
Mine eats more oil when it's hauling, not less. I gave up and installed a catch can. That should be considered a mandatory mod on 6.4's at this point
@@backwoodsbuildingandfixing9223 catch can or vent to atmosphere, personally I haven't heard many people deal with oil vapor issues for it to be common
@@nativeoutdoors1780 Vent to atmosphere? Bud, this isn't the 1950's. And I guess you haven't been around a lot of 6.4's, excessive blowby is "normal" for them
I thought I had: If your motor has excessive blow-by, you could always just install a catch can. You can even build your own. Just take a big can, put some steel wool in it, then route the piping through it, so that the oil will condense out of the stream before going back into the intake
Andrew if youre building up enough oil in your intercooler to constantly blow blue smoke if you dont "work it", you have an issue. Either excessive crankcase pressure(even for a 6.4), or a turbo seal feeding that much oil. Condensation buildup in the intercooler was a true problem. I own two 6.4s(250 & 550) and have had the excess buildup appear in both. Conditions were always rain or high humidity, driving steady state/easily(say 10minutes) and then the next time you step on the throttle for some power boom big cloud and stuttering. Condensation can unfortunately be a natural byproduct of rapidly cooling air with a high moisture content. Unfortunately fords intercooler collected this condensation. They even had a TSB and new part made, which the problem still occurred. Try a new mishimoto intercooler, never seen the problem since. Even on my 5k miles road trip with rain/high humidity and all the steady state easy driving you could ask for.
Love my 6.4. The people that hate on them have never actually owned one and those who did own them blew them up cause they threw huge tunes on the truck and floored it everywhere they went. Delete it and run a MILD tune. Keep up on normal maintenance like you would on any other diesel. Drive it like a truck, not a sports car. I appreciate you taking the time to go over all of the issues they have an actually pointing out most of the issues are emissions or improper maintenance related.
Good for you brother, I feel you and ride with you ...... Superduty Services, 6.4 on a 25k budget. It’s a UTube video of my truck that I just had completely rebuilt .
If the factory tune would have been cleaner (CAT did it great back in the late 90's for Pete's sake) the DPF would have been so much more efficient. Navi enriched the base injection timing and duration to the point to where it preheated the DOC to preheat the DPF faster. That "rush to achieve temp" was the nastiest smelling, DPF meltdown recipe. Who ever lead their R&D on emissions was paid too much.
Just give it some time, that engine fails in stock tune all the time.
@@marksrepairj623 Classic denial. The 6.4 is one of the worst engines designed. Cannot understand the mini cult following. Can't even find the high quality parts from ford anymore either. Better off trading it in now before it's too late.
Speak for yourself lmao. 28k, spun every bearing in the motor, then at 32k, it threw a rod out the side of the block. Thing was the biggest piece of shittest thing we’ve owned.
I’ve never seen a 100% stock 6.4 that made it to 100k without at least one of the issues you mentioned. If you have a later 6.0 (2005-06) and you just drive it, and leave it alone, they are good engines and sound amazing. I’ve seen more automatic transmission failures. The three 6.0’s I have are 6 speed manuals with 246k-301k miles.
I almost bought a 6.0 regular cab with the 6 speed manual about a month ago to go along with my 7.3, but I was a little nervous and waited to long. Looking back after reading more about it and watching UA-cam videos I wish I would have just snagged it up.
Agreed! The 06-07 are the best years in my opinion.
The transmissions are the same with 6.0s and 6.4s and they are actually really good
We had about 4 or 5 6.4s in our fleet that had 350+k miles all hauling heavy. They had lots of little stuff but nothing major. They just suck ass to work on. Gotta pull the cab to pull the passenger valve cover to change some fuel components. Stupid
@@garrisong That’s what mine are, plain Jane, hand crank window, steel rimmed, single cab 4x4’s lol.
I have a 6.4 in an 08 F350. Mine went 279k before I had an issue with bad fuel (delivery driver dumped gas into diesel tank) At that point I decided to pull it and do a full rebuild. I highly recommend the Kill Devil Diesel kit. Crank was still within stock spec. This motor definitely has some issues, but for me it was a lot less expensive to rebuild it with better parts, and leave off the problematic components, then dropping close to 100k for a newer truck. 12k miles on it now and pulls like a dream!
So did you sue the gas station or delivery company for the cost of the rebuild? Because that’s really the only logical response here…
I don’t think you should have to sue right away, they probably have business insurance.
This is why i ONLY get diesel at the exact same gas station. Easy to prove where your fuel came from
I worked at Navistar in Huntsville, Alabama when this engine came out.
One assembly line was sending them down and conpleted - I was in a second line that all these engines, after testing, were coming back due to testing failure/rejections. I tore the heads off so many 6.4s its unreal. The entire program was a failure. I met an engineer who worked on the injector system there - he was telling me the nightmares they dealt with talking to two separate teams (Ford and Navistar) and how the bureaucracy was intense and doomed to fail.
I realize how chaotic the mid-late 2000s were for manufacturers-
I truly blame the EPA for killing the diesel market right around the time of Hurricane Katrina.
FUCK EPA!!!!!!!!
What were the main problems you saw that caused the 6.4L testing failures/rejections
Maybe we should pay attention further to what's going on in Washington instead of cardi B and all them other idiots
I live in Huntsville and am buying a 6.4 tonight. 177k miles, deleted, tuned, etc.
@@getstuk87 was told they failed NVH testing on the line 🤷♂️
Thats all I know and what the engineer who moved from Michigan who said it was a disaster...
My 6.4 is deleted and tuned AND I maintain it regularly. Runs like a beast and love it way more than the Duramax that I had previously.
I’ve got a duramax and looking into getting rid of it for a 6.4 just not sure about the 6.4 power stroke
I had three trucks 2001 dodge 2500 Cummins bought new
2005 Duramax and 2005 f 350 dually and the most powerful dependable truck outta all them was the GMC duramax pulled my 36 ft 5th wheel so well I honestly didn’t feel it was on the truck
My Cummins great reliable truck was under powered couldn’t haul that 5th wheel it struggled up hills but the worst was the ford 6 litre diesel gutless money pit ffs that truck would turn itself into a ford dealership on its own lol
My 2008 6.4 Sounds Like a Fighter Jet.
Runs like a champ.
I love to hear that sound pulling my boat.
I have a 08 6.4 which was deleted very early in its life, just rolled 350k miles with little to no big issues, makes great power when you need it, looks great, sounds great, I'll keep it going until it completely dies
This was such a clean video - I stumbled across this when considering a clean, well kept ‘08 but knew there were issues with 6.4 and wanted to learn more. The information, graphics and pace of the video were perfect in my opinion. Subscribed as a result.
You make my appreciate my 7.3l that much more lmao.
Yeah definitely I wouldn't trade in my 95 7 3 for anything less
I almost bought a 6.4 then did some more research and he made me change my mind and get a 7.3
Had many 7.3 and while they were good for their day I’ll never go back. I had decent luck with them but they all fell apart on me when using them for heavy towing and very inefficient designs that today’s technology has passed, it not a bad engine but I love my 6.4 and hate my 6.7 with a passion also I had a cr Cummins that I would consider getting a blasting license just to use on that truck
@@ni1469 so you’d rather have a junk 6.4 the worst powerstroke over a 7.3 and a 6.7 powerstroke I hope yk the 7.3 and the 6.7 is one of the best diesels made the damn 6.0 is more reliable than the 6.4🤡🤣
@@ripperlipper1016 your high if you think the 6.4 is one of the worst engines ever considering the 6.4 max force is still a beloved engine in medium duty trucks and the only difference is different pistons. And it’s very well reviewed also. I also have thousands of hours wrenching on powerstrokes going back to 2007 both my fleet of vehicles and for customers. The 7.3 was good to a point but had a lot of issues the 6.0 sitting in my driveway is waiting for a shop bay because it lifted heads again. And the 6.7 is the most regrettable purchase I’ve made we’ll let me rephrase that the filing cabinet worth of repair documents is more regrettable than anything. Owned every power stroke engine and the paper trail and hours spent repairing proves your statement to be incorrect. Also if 6.4’s are such bad engines why can’t delearships keep them on a lot for as long as 7.3, 6.0, or 6.7 which sit and wait for a buyer but the 6.4 sell ridiculously fast right now
As I mentioned in a comment on another of your videos, I am a fleet mechanic for a public utility that uses F550 trucks with Powerstroke engines. Our bigger trucks are International using their Navistar MaxxForce engines.
The 6.4 was my biggest nightmare. As you pointed out, cab removal is the preferred method of many repairs. But our trucks either have a boom or rack hanging over the cab. Cab removal is not an option when the engine is dead. The repairs can be made but it isn’t fun. If you don’t own a good 6 point 10mm wrench, don’t attempt any in cab repairs! You will never get the exhaust pipes off!
EGR or DPF delete is not an option for us because the penalties are too severe in California. But, Bullet Proof diesel makes legal upgraded EGR coolers that are excellent. They neither plug or rupture. They also make an upgraded oil cooler that allows the oil filter to be remotely mounted as a spin on filter; I do like the coolant filter shown in your video. I hadn’t seen that before.
I cannot stress enough what you said about the fuel system. Keep that water drained! Also, most people don’t change both fuel filters, they change the one under the hood but ignore the frame mounted filter on the lift pump because its a pain in the a$$ to change. You must change both. The high pressure pump is too expensive and a nightmare to replace if you ignore maintenance.
I would like to add another problem we experienced on the 6.4. Thermostat and housing breakage. I think this may be due to cavitation. But we replaced a lot of broken thermostats and damaged thermostat housings. The thermostats literally break into pieces and it damages the housing.
Thank you for your video. A cool look into my world that I am happy is now in the past. The 6.7 has been better but still not fun to work on.
I remember reading that forum post on a website about 8 years ago where a guy was lamenting that are nicer-looking truck came with a Cummins engine but had a $10,000 premium to the exact same truck in a little bit worse condition with a Maxxforce engine.
Guy has one for sale cheap. They changed the oil and filters and now it has blow by and runs ruff.. any ideas
Coolant filtration sure eliminates cavitation.. I even just ordered one for my 96 7.3
@@SpaceRanger187 did you find out the problem with the truck?
6.4s do have one upside. Perfect Cummins swap candidates 🔥
That is the stupidest thing I’ve ever heard
Theres a guy around me with a cummins swapped 6.4
Ahhhhh the powersmoke debate! I’ve never had a 6.4 because they sounded scary to own. I’ve had a few 7.3’s and on my second 6.0. Love the 7.3’s, once you know what they need. You can run em a long time. The 6.0; once you know about the IPR, ICP and the FICM, you can keep ‘em running ok. Once you delete the EGR and pop in a 58volt FICM, I think I might get 500k out of this thing. My platform is a F550, plow, sander(in the winter)and in summer. She hauls around equipment; skid/mini. If you’re gonna run any powerstroke, get yourself a scanguage and learn your baselines. For reference my truck is a 2004, no spring chicken but goes like stink and the MPGs better than my Lexus! Oh and for all those nervous nanny “govt is gonna get me” because I deleted an 18yr old truck. The govt is afraid of me, not the other way around. The way it was intended.
Agreed on that you've got to delete those 6.0 but if you think the govmints afraid of you and your milkshake maker. Then you must have forgotten they killed US citizens with drone strikes. you use that thing for work if dot Catches you well you'll be Elmer fudpucker alright
@@yzrippin In my area no-one gives a shit. I never run any emissions shit on anything and no-one cares.
The government wouldn't be coming to get anybody for trucks that were made before 2008 just like they're not coming to get anybody for driving a 502-swapped 70s Camaro resto-mod. But thanks for the dumb grandstanding.
@@yzrippin I’m not for hire, no DOT for me. I worked for the govt for 13yrs, I know exactly. What they’re capable of .. still not afraid. (USAF/OSI-Retired, Blue card)
When I bought my 6.4 it had been fully deleted since near new, but like you I was afraid because of the bad press. So I've had this Cummins waiting, but my 6.4 just went over 311,000 miles and still strong. I love this 6.4 power delivery, instant. (tuner)
Companies like Kill Devil Diesel and Choate Engineering who specialize in knowing the 6.4 as well as 3rd party builders came up with fixes for the rocker arms by simply adding to the stock valve covers or making valve covers that oil the rockers. Also to note more information, being that the 6.4 Powerstroke pistons issues are based on FORD designed pistons, the solution to fix those is simply grab Maxxforce 7 pistons because those were better designed by INTERNATIONAL, as well as if getting crazy enough you can buy a kit for the 6.4 when rebuilding that allows you to, if bored out and so forth, to put the steel 6.7 Powerstroke pistons in, though the Maxxforce 7 pistons ate obviously an easier and just as good of a solution anyways. Also worth noting for fueling its good to also add Fass or Airdog lift pumps, helps solve the issue more than just the stock system, though again as mentioned in the video maintenance overall is key.
My daily driver is a 2009 F350 6.4 that i bought new in June of 2009. I deleted the dpf & cat in 2012.

326k on mine and still going strong. Do the damn maintenance..
I absolutely love the 6.4, it's the easiest engine to make power out of, just delete it maintain it, and turn that chip down and pretend it's not a hotrod while your towing heavy, and it'll do you right
My deleted 6.4 has 319,000 miles. Replaced the auto trans at 268K. I back out when pulling heavy on long grades here in Oregon and the West.

I worked at International dealers for 10 years. The jankiest warranty repair I ever seen was on the 6.4(Maxxforce 7) that involved epoxying the block on the outside and removing a freeze plug and epoxy in the coolant cavity. This was due to a weak spot in the casting that would cause a coolant leak, either external and/or internally.
So what’s a way to recent or fix this issue

@@ueatbetteritrainbetter6706 Is it loosing coolant? Does the white smoke have a sweet smell to it? Has the egr cooler been replaced? Whatever it is, it's not what I was describing above because if it was you have coolant in the oil and not in the cylinder like you're describing
After the delete (90,000) I love mine. Crazy power, great puller! My biggest issue has been milage and cracked radiators. Delete took milage from 6.5 to 13.5 and Mishimoto radiator and support bar cured my radiator problems. Also have a 7.3 and it's one of my all time favorites but you won't get the power the 6.4 has. My 6.4 should be a little over 750 hp, don't even know there's a trailer ( 10,000 lbs and more) back there.
My 6.4 was tuned and deleted. ... I wasnt nice to it and had almost 160k when I got rid of it.
I heard them radiators are bad about cracking
@@swashington942 yeah, the mounting system that ford used would literally try pulling the plastic tanks off of the radiator which ford mounted on the sides 🤔 when the front frame twisted on uneven ground or under torque. Went through 2 stock ones ( not an easy job) before the mishimoto radiator and support bar.
Just traded my '09 6.4 for a '22 6.7. Like the individual said in the comments section...regular maintenance is key to success with this engine. I did an Oil change every 3500 to 4000 miles, fuel filters every other oil change. I used fuel and oil additives that reduced my regen cycles. I kept my 6.4 stock with no mods. Ran it for 150,000 miles with no problems...except for typical Ford rear fender and tail gate rust / rot. I pulled a travel trailer and a horse trailer as if nothing was behind me. Sounds like I got lucky. My only complaint was all the fear put in me by 6.4 haters.
thats only 150k though
@@elijahantrobus9034 150k miles trouble free on a 6.4 is nothing to scoff at. Most didn't even make it out of warranty without needing 1 or even 2 new engines. Goes to show maintenance is key. Period

With all this hate on this engine I’m scared every time I drive it thinking it will be the last… but it is still going strong with 144k miles and dpf and egr out of the picture
@Nate Placko Yes, they'll go 180k. The trouble is once they blow you have to do everything and it's $20,000.00.
So at that point do you buy a new Hyundai for the wife or do you put an engine in your 180,000 mile 15 year old pickup truck?
I have a 08 6.4 with 425,000 oilfield miles on it. Has been a awesome engine! I have changed oil and all filters every 5,000 miles. I use nothing but motorcraft oil and filters. I love this truck!!!!
6.4s are tough and reliable with deletes and tuning with normal Maintenance.
My favorite engine!
I own one and it has 170k in completely stock form. Probably a unicorn. Frequent oil changes with Motorcraft filters. The truck has given more issues than the motor.
I’ve had the exact same experience with my 6.4. I doubt yours is a unicorn. Unless, I also have a unicorn. My daughter would appreciate that… 😁
Two words for people like you: LOTTERY TICKET
I have 150k on mine. And I love it.
Enjoy your last 30-40k miles while it lasts 🤣
@@DieselObsession until your comment I didn’t realize how low the mileage was on those “good” ones. Lol clearly not working trucks. They wanna know how good or bad something is they need to tow 15k or more everyday across the country. That definitely separates the trucks from the Ridgelines.
I luv had my 6.4 for 2 1/2 years and have never had a problem with it.
I vote with Bill Hewitt. 6.4 is eventually a timebomb and when it goes off, it tends to leave very few usable parts. 200K is about as much as you can expect.
That's generous REALLY generous lol I seen 3 make it past 110k in 7 years at ford

I worked at International dealers for 10 years. Seen several 6.4(Maxxforce 7) grenade with under 10k miles. Most liked to go around 70k. They liked to eat the camshaft and send metal through everything. No choice but replacement.
Bill Hewitt was the guy who said if you do the crankcase vent reroute, it blows turbo seals. Dude’s a clown. Had a buddy get headstud’s done (along with other things) at his place they snapped a head stud in the block, glued it back together and sent it down the road.
I know a guy that bought a 6.0 then a 6.4. It was a farm truck. While getting a round bale of hay the flamethrower exhaust set 500 round bales on fire. He drives a Dodge now.
Farm truck hard to beat the idi or the old cummins
Thank you for a great video. You took some fear outta me looking at a 6.4. All the comments with experiences are very helpful as well. Thank again.
One of the biggest problems with 6.4 is quality replacement parts
I own a 2008 6.4L f350. Like most I deleted my DPF. Replaced my radiator to mishimoto all aluminum. I installed an aFe cold air intake. Replace my exhaust pipe to straight pipe. If you replace your straight pipe and your engine light is throwing a code because of the exhaust pressure not being detected. I took the exhaust pipe that I bought to a shop fabricator and have them put the holes on the new exhaust where the censor would be and that fix the problem. I upgraded my water pump to bulletproof diesel water pump. I also installed and (AOS) Air oil separator. I also installed a Sinister diesel coolant filter. I also replace the head bolt to ARP. I don't use my truck for racing but for towing and the truck performs just fine. My truck millage is 236,000. I am still using the original injector and Siemens fuel pump and also still using the same turbo. The truck is still ticking and have no issue. Also I am H&S programmer.
ED, drilled/ threaded exhaust manifold for the backpressure sensor to get out check engine.
A fix for the positions is putting in a set of Maxxforce 7 fly cut and de-lipped pistons with the titanium nitride coating. That's what I have in my 6.4. The rocker arm issue can be taken care of by a company that makes a set of oiling valve covers that put oil directly on the rockers within several seconds of start up.
Choate engineering
@@lamarzimmermanmennonitefar5269 that's who built my short block.
Where can I find this
Yes, now it's a good truck right?
Just correctly built a 6.4 on an 08 f450 KR. Stock turbos, Bosch injectors, completely deleted except the air/oil separator(coming soon), fuel system tuned slightly on the conservative side, have been very satisfied with it.
With deletes and tunes with normal Maintenance,these things are incredible,got a 09 with over 205k ,no issues,,it’s a strong worker.
Very proud owner of a 6.4 with with tuner and propane injection. This motor motor makes massive power and 40+ pounds of boost. 08 f450 king ranch
Saw that you posted this two days ago. I'm sure it's blown up by now. Unless it just sits in the garage
Your coping pretty hard lol
Nope always been a solid truck. Had a dpf issue at 60k. Strait piped it and run a mild tune. Tow a trailer everyday with it. Thanks though. You probably drive a dodge am I right?
I had a 2010 Deleted and tuned. Loved everything about the truck. The ride, the interior and man the power. I totaled the truck when I hit some ice. I got a 2017 new, it was a reliable truck, but just didn’t have the pop (thrill) of the 6.4. I just traded the 17 on a used 20 and now feel better about this truck. Towing this truck is a beast. But I still Kinda wish I had endless cash flow and could get a hopped up new 6.4 engine for just hot rodding or green light racing kids in town. Was such a fun truck.
Please note the aftermarket cold air filter. I have to agree the stock airfilter was far too restrictive. Much better preformance once replaced.
I have a 2008 F350 with the 6.4 and it has 355,000 miles on it. The truck is completely stock and has never given me any problems. I am very diligent about the maintenance and I think that is the key to these motors.
Do you mind sharing with me your maintenance schedule that you follow ?
I just bought a beautiful 2008 but it has 214k miles on it. I just want to give it every chance to get to 500k miles at least
@@mattgodfrey7394 tunes deletes and maintenance every 5-10k miles
Ditto. Can you share the maintenance schedule with us?
I find it HILARIOUS, all the guys defending piles of shit like the 6.4 by saying, "being diligent about the maintenance" or "change my oil every 3,000 miles with super expensive synthetic oil and a $100 filter", and "so far I'm happy with it".... Okay.... Let's liken this sad, cuckish way of thinking for juuuuuuust a minute here:
Let's compare the 6.4 to a girlfriend/wife. Obviously, this chick is NOT reliable or trustworthy. Let's ask the 6.4 lover to tell us about HIS girlfriend :
"Well, maintenance is KEY to making her trustworthy. I'm not gonna say WHAT all I do to her/what all she does to me, but SO FAR, she hasn't f - - - ed anyone else! That's the key with these girls! As SOON as you let them go ONE day without looking at them, they're gonna screw your best friend and wipe his nut on your pillow. Feed her cheap food? She's gonna give you Herpes and file for divor
I purchased a 2010 6.4 superduty. I've heard all the horror stories of this engine. I saved up my money all my life so that when I retired I could buy my dream truck and hit the road in my fifth wheel. I bought it new when I retired. I am faithful (maybe overboard) at routine service for his engine. Ford has completed all recommend routine and critical maintenance on my truck even before the recommended mileage. Yet with all my TLC, I have had to replace #3&4 exhaust heat sensors at 32k/miles (warranty covered). Repair cruise control twice at 38k, 45k (warranty covered). Replace the radiator at 103k miles($1,1k). Replace the alternator at 112k ($1.8k). Repaired the EGR cooler due to a gasket leak at 115k ($3.5k). Replaced the high-pressure fuel pump TWICE 102k and 113k. (2nd covered by warranty) ($4.5k). And today, I sit broke down due to a turbo failure at !55k mile and a whopping $6,100 repair bill! I am sick. My dream is a nightmare. Worst of all, almost every repair has required lifting the cab before they ever begin working on the problem. So before they can even work on the problem, I've racked up 8-12 hours in a repair bill before they even begin repairing the problem lifting the cab. How sickening of an engineering design is that. I watched every video on youtube and I don't care what anyone says, I'm telling you from experience, regardless of babying this engine, you can't afford to own one. Not only monetarily, but in time down and stress. I'd junk it in a minute, but my fear is, I'd just be trading it in for another piece of Amerian Engineering junk. Possibly with all the deletes, and modifications mentioned here, this engine might function. But think of what we're saying. Thousands of dollars would be spent only to create an illegal engine. That is a sad testament to American motor companies.
You should have deleted. 260k on the dash, fully deleted and been on the hd300 (mini maxx) for 6 years now. I’ve replaced the turbos like 3k miles ago and besides the turbos, I’ve only done batteries, belts and ac blend door. I just drove the truck 400miles a few days ago to my parents to house sit, my brother lives 10mins from her with a big barn. We plan to pull the cab today (cuz he wants to experience it, he is a diesel mechanic) but we are replacing glow plugs and I’m going to clean everything down. I would highly recommend the delete.
Sad state indeed, my friend.
When I switched to a Diesel engine truck, it was for a better towing and mostly reliability. I wanted a Powerstroke for the speed, but I needed the Cummins for reliability. I’m just glad Ford learned from the 6.4L mistakes to keep their customers.
Obviously you buy a truck with a bad 6.4 and put a cummins into the truck.
@@nou8257 they're basically impossible to find
@@wizard_of_poz4413I see a decent amount of 6.4s always up for sale around me. Crazy part is they’re all over 300k miles (deleted) except for like 2 that had under 100k which were still stock too.
@@David-zo9oi yea plus they're really nice trucks and have a ton of power
I have a 6.4, and a very good diesel tech at my disposal. The truck's now 12 years old and no longer a daily driver. Has about 120K miles. I have always maintained it at the heavy duty maintenance service intervals, and run shell rotella and motorcraft filters. I change the oil when it gets dark and smells like diesel a lot, well before the recommended interval. At 100K miles I replaced all hoses, the radiator (cracked expansion tank from frame flexing) both EGRs, water pump, head studs, oil pump, and had the DPF baked out. A bunch of other stuff too. The truck has been flawless since then, and my diesel tech says I'm good for another 100K miles. Probably looking at a turbo replacement eventually. If this was a work truck or daily driver I'd have a tough decision to make. I don't even need a pickup anymore, but I have never not had one. I would not recommend anyone buying a used one, but that would apply to a lot of diesels and trucks. You don't know the maniac would owned it before you.
Sounds like you’ve definitely maintained yours really well. Gotta be careful buying a used one, since you never know what kind of maintenance was done (or not done)
My biggest problem with the 6.4 is how complicated it was to work on in the Super Duty. Nothing was easy
That's all v8 diesels
A 6.4 can be a good power plant like any other with proper solutions done no doubt, it still doesn’t change that they remain to be the most expensive diesel to own in a pickup to date. Most of our regular customers went to 6.7 Pstrokes because they were cheaper, but maybe it’s different in the U.S. economy, this Canada so that might change it up? Awesome video dude! 👍🏻
No, its not a good power plant with proper mods. Please stop telling people stuff like this.
In 2011 I bought a used 2008 F250 from the dealer and still drive it today. The first year I owned it, the DPF and EGRs caused the truck to go into limp mode several times. I did consider selling the truck, but instead of getting rid of it, I deleted the DPF and EGR with a stock tune. Today I have over 200,000 miles on the truck and have not experienced any issues since. I have always ensured that my vehicles received all required services at the appropriate intervals; the F250 is no different, including changing fuel filters every 30,000 miles per the owner’s manual.
My only complaint is that the OEM radiator had to become replaced three times; all of the Ford OEM radiators started leaking in the same spot every time. Several years ago, I replaced the radiator with one from O’Reilly Auto Parts, and it has not leaked at all; the Ford OEM radiator for the 6.4 is hot garbage.
I love my fully deleted 08/6.4 PS once you do take the cab off it isn't so difficult it adds about a total of 2hr to the job, that's off and back on not the savings in time and comfort in the wrest of the job completely makes up for it. Of course, you do need a high ceiling and now room for like two vehicles but with a few 2X6X10s you can just put it on the top of the box you might be able to trim the wood down to like 7ft. But you will love the access it gives you
I have 2010 6.4 with 190k miles.
I absolutely love it. Its fully tuned and deleted and it was deleted early on.
Im the third owner and pull pretty heavy loads but not every day
The power is amazing i beat a 2019 high output cummins while puling my tool trailer 😂
No engine problems at all so far. I change all filters regularly and baby the truck 99% of the time.
I believe if you take care of your things they will last ( with delete in this case ) stock 6.4s self destruct
😢😢🎉❤😂😂🎉🎉
Absolutely fantastic video!! Thank you for all your research, and efforts to explain the issues with this engine.
My 6.4 has 364,000 miles on it and still runs strong, fully deleted as well.
My 2009 has been fully deleted since 70k miles. I have ran a 600 hp tune on fully stock 6.4l since 100k miles. My truck has never broke except blowing some boots off. Never a major failure with 10k oil changes.
On my 2nd 6.0 (first was totaled in an accident), good luck with both so far. I’ve heard too much negative feedback on the 6.4 from both owners and people who work on them to buy one. My next truck will be an 08-10 F450 with a DT360 swap. Wet sleeved, mechanical injection, 100psi on stock head bolts.
6.4 owner with 360k. Original drive train. Never rebuilt. Minor modifications. Regularly towed with and beaten on.
I’ve had my 08 6.4 king ranch since brand new, deleted everything at 125k and added a tuner, wished I’d done it at 25k , even so it is in my mind one of the fastest smoothest running engines on the road, I’ll never sell it, keep up regular maintenance and it’s a beast!
I've seen a 6.4 with 345k miles owned since new, been left stock its entire life and maintenance been kept up with. I also have another buddy who has one with 240k and its gone through about 4 turbos in its lifetime. It's really a hit or a miss.
Yeah it just isn’t the best design. The real issue with all diesels in general is a lot of guys put tunes on them it makes even okay engines look bad.

I did the egr and dpf delete on the 2008 f350 and I never had an emission since I did the delete. My truck was broken in by hauling a 16,000 pound fifth wheel from coast to coast in Canada and some states. It has 112130 km or 69,668 miles on it and it’s runs great.
Only worked on power strokes for the last 8 years and 6.4s are by far the least dependable and most expensive to repair in my opinion. Have one in right now with cracked pistons and leaking oil from everywhere with less than 180k miles
Less than 200k on a decade old truck? Tell us more about how the owner neglected regular maintenance and ignored the warning signs...lol
I owned a 08 6.4 since 2017, my first diesel truck and have driven 40k miles, serving the purpose of building and repair projects, w occasional travel. Had issue w the egr system since day 1, CEL was on from stealership :( I cleaned both egr coolers real good, and replaced the egr, agree the stock ones are easy clogged w silt. )
Had a non start due to bthe lower fuel pump leaking, learned my lesson to not to “service” these pumps.
Replaced radiator and thermostat (per techron postmortem suggestion). Replaced brake pads and rebuilt a brake booster (the thing that builds pressure for braking).
It’s my work truck for my building project, I hope to maintain it and drive it till I have my own garage when lifting the cab is possible so I can fix the oil leak somewhere, p0081 code related to high pressure fuel pump. I believe also dpf dumps a lot of unburned diesel as every time I change oil, it has more I put in. I also noticed the coolant level drops a bit over the time.
If I knew and had the money, I may just buy a new 7.3 diesel. No regret though, as the experience is precious and I appreciate the high boy has served me so far.
I have two 6.4L and I change my oil every 3500 and fuel filters every other time. They are both completely deleted and tuned with the old Spartan tuner. So far they have been good, one truck has 195K and the other 155K. Maybe im just lucky, but I dont reallly abuse my trucks.
I have a 08 deleted 238 mil dashdaq tuner, pull the maintenance, don’t beat it , I do play , have friends with Chevys snd dodges, with a lot of money in them, they can’t touch the 6.4. Very suprising.
After watching the video and reading the comments, I'm glad I went with the 6.8 in my 08.
My dad had a 6.4 that he bought new in 2008, the truck was deleted in 2017 when the egr valve failed. Previously under warranty the rear main was replaced and radiator. After the truck was deleted it was a great truck other than the radiator which we replaced ourselves in 2020
Single vgt turbo on my 6.4. 230k no issues other than the stock turbos died at 200k love the power this truck makes!!! Would strongly recommend the single with a vgt housing tows like a dream.
It not that power ful nor efficient.
I have a friend who owns a 2010 F350 with a 6.4 in it. He has had all the issues a 6.4 can have. It recently broke a piston and $22,000.00 later he got it back and 1000 miles later he had to gave the heads replaced again. Another $1200.00 and it seems to be running well, he did do a delete before the piston problem, maybe should have done it sooner. Truck had around 60,000 when he did the delete and had about 80,000 when it failed. Hopefully it will give a lot more years if service now.
I didn't add that because of what I read about the 6.4 when I bought my Super Duty I wanted a 6.7 and after investigating a little I knew it had to be a 2015 or newer because of the upgraded made at that time. I tow a 33ft trailer with a Polaris XP 1000 on the back of my truck and it flies up the mountains. I get between 9mpg to 11mpg normally, have gotten as high as 13 with it stock, just deleted it to get rid of exhaust cleaning. Haven't towed with it yet. Not worried about fuel economy, worried about my engine lasting as long as possible. Awesome truck, not a fantatic, think people should own what they are happy with, it's your money. I just happen to like my Ford.
He was probably a shitty owner
Correct me if I'm wrong but it's the only twin turbo diesel Ford ever manufactured .
Love my 2010 6.4L put a lot of work into it, new up pipes, new turbos, deleted it, cold air intake, medium tune can produce over 900 ft lb of torque and 42 LB of turbo boost, top end 139 (wish i had a 6 speed).
But cruising Highway empty 18 mph.
And lots of regular maintenance with high-end fluids and filters.
Engine grenaded at 141,000 miles. Pistons 7 and 8 failed on a hill towing 10,000 pound trailer. Did full delete and a reman engine. $17,000 later people said I was crazy. So far so good. Now folks say it might have been a good idea considering you probably will have to wait a year to get a new Superduty. Also the truck seems to have gone up in value.
Wtf, 17k for a reman engine?? 😳
Yeah, you just spent 17k and all you have is a new engine in a 140,000 mile 15 year old truck.
@@jeffwhite3021 True, but have you looked at the price of a new or used diesel superduty? Still feeling good about the decision. Also truck has zero rust.
@Steven Wilson For me personally, just seen too many ruin vacations for people as well as hitting hard-working guys in the wallet. They also cause a lot of techs late nights at work, missed kids games and lost wages.
@@jeffwhite3021 Once again true. They had my truck for three weeks. Had to drive the minivan for three weeks. That sucked. But everyone knows it was the DPF filter and regen process that did this. This change happened during the Obama admin. That is who I blame...Obama. By the way still have the truck and still running great.
My Grandpas 2008 f350 lariat has the 6.4L in it and it has never broke down since i was born in 2009 he bought it brand
new and after 1 year of owning it he put a computer/chip in it and it has worked ever since and has pulled many many heavy things and it still runs like a top
So the best fix for a 08- 10 super duty with the 6.4 is a fummins swap.... good info
At least you probably could get them dirt cheap especially after they blow up
Also a 05-07 super duty with a 6.0 is a fummins swap
As a diesel mechanic, do not buy a 6.4 powerstroke. They're prone to absolutely killing themselves. My shop won't work on them, we were sued for doing a tire rotation a week before the motor detonated. The judge found us and the 2 shops that did work on it before us guilty because we were the last so to work on it. The truck had no motor work done. For the same reason you won't even find a Ford dealer that'll work on them.
Love my 6.4 in my 08 f450 7 years ive had it zero issues. Deleted and mild tune
Mine is Deleted and turned.I keep the tune modest like stock or Tow. Tow gives me all the power to tow my 36ft trailer all over and through the Northern Rocky Mountain range. But I did have to Re & Re the Trans. With a couple of up grades shift kit later model reverse and a couple minor changes. That trans lasted 135k mi. Now we will see about the rockers 😢 I'm hoping it last much longer maintenance is a little better than as needed
Ford 6.0 and 6.4 owners always have astonished me. “Oh it’s a great engine, you just have to do this, that, and these things, and after thousands and thousands of dollars and tens, sometimes hundreds of hours in the shop, down a truck, it’ll be reliable and able to handle anything!” Until it inevitably breaks again.
Look, a diesel engine isn’t great, or good, if it won’t last at least 300,000 miles. For Pete’s sake, most all Diesel engines are built with super heavy parts that don’t wear hardly any, especially with how much work the majority of these people do with their trucks.
As cool as the 6.4 or 6.0 may sound, and as much power as you might be able to make them make, they’re still garbage engines and have a cult following because some people just love working on shitboxes not worth a cent.
Gotta disagree. I guess you can prepare to be astonished. Got my 6.0 for 8k and put 6k into it. 14k for a diesel truck that runs great is a pretty good deal. If you are the guy that takes thier truck to the shop every time it breaks then yes, I agree. Stay away from the 6.0. For the money, I will keep the truck alive vs having a monthly payment on a newer truck. How much are new trucks now?
I own my houses, owe $0 to credit cards, owe nothing in car payments. I would call that a win even if in the future I need to put a few thousand into the truck again.
Amen. I'll expand on that, any person remaining fiercely loyal to just one manufacturer astonishes me. I used to be that way. Then I learned that repairing my work truck frequently purely because I want a specific brand is bad business. Maybe if I expand the scope of the field I could find a more reliable truck that can keep me on site and on time. Engines dissolving from poor casting? I mean that alone, how does anyone sleep on that?
I will say though, *without sarcasm, I credit my early experience with Ford trucks for advancing my capability in industrial repair.
Even with dodge diesels you have to replace trannys and that’s not cheap bro that’s the same price it cost me to bulletproof my 6.0 the 6.4 are bad engines but the chevys had the injectors doge has trannys and ford was just head bolts for the 6.0 so eveyone had their downfalls
@@daniellucateroofficial4041 the 6.0 wasn’t just head bolts. The HEUI system was horrendously unreliable, 6.0s always have cracked heads, the oil cooler is awful, and so is the EGR. The FICM can fail easily, and so can a handful of things I haven’t listed.
Being brand loyal is stupid.
Also, if you go back and look at the warranty claims, ford had a ton more with the 6.0 than GM did with the lb7 and Chrysler did with transmissions.
@@rudyruiz9521 how would you call spending that much money on an engine to make it a little more reliable a win though? Quit being brand loyal lol. There’s a reason why the big 3 sell junk, it’s because people happily buy it.
Bought 2008 used with 179,000. Its full deleted with tuner. After 2 months water pump went out which led to bad clutch fan which led to bad serpitine belt. Other then that ( which its a hard truck to work on ) no problems. Pull trailer everyday getting 20 MPG. Crazy amount power with the tuner. Im now at 215,000. Lets see what happens ! Thanks for video
I am married to my 6.4. Once my #7 piston cracked I had a dilemma. 45 to 60k for a decent used truck or roll the dice and see if all the issues could be fixed. I went the cheap route. 20k later I fixed all of the issues you mentioned. Fully deleted, intake and exhaust, head studs, upgraded pistons, lift pump with better filtration for the fuel system even vented blow by to atmosphere. I run it with a tune at about 450 hp and it is great. But I am always nervous about it and still only get 14 or so mph. I could never say that the 6.4 is really good as an option for anyone to buy.
I have been 'nervous' for years. Bought a swap Cummins setup, but my PS is at 312,000 miles (deleted) with a tuner and gets 19/20 mpg empty DRW F350. Lowest I've gotten towing in Western Mountains up to 85 mph (14' camper trailer Jeep) was 14 mpg over 3300 miles this winter.
They also have wrist pain issues as well. They did not come with wrist pin bushings from the factory so you have to get aftermarket rodes with bushings in them in order for the wrist pins to last
6:35 That’s actually a myth. The purpose of an egr system is not to burn fuel in the exhaust. The exhaust is just being used as an inert gas to cool the combustion chamber to help with nitrogen dioxide emissions. Whenever you superheat air, the oxygen molecules fuse and make no2.
That is true and the 6.4 does NOT have a variable geometry turbo like the 6.0. It has a dual turbo set-up, one small one large.
@@rondye9398 It has a dual turbo setup, but one of them is a VGT with the other being fixed geometry.
Exactly. Unburnt hydrocarbons are typically the realm of the DOC.
I bought my 08 F250 with 98,000 miles it seemed to be very well taken care of the first day I ordered the delete kit then it was complete within a week I’ve had it since 2012 in all I’ve ever done to it is change the oil every 5000 miles fuel filters and I only use Motorcraft filters. Till this day I still have not put a wrench on it except to change the alternator belt tensioner and replace the batteries that’s it
I have a 2008 and I love it. Bought it new and have put 235k on it. This truck works hard every day. Runs great and crushes just about anything on the road in a climb, even fully loaded. I've never wanted for power and have pissed off/punked lots of dodge and chevy guys over the years with it, dudes in sports cars too. I will admit that keeping the coolant system free of leaks is a challenge, and the DPF system is straight garbage.
Cab mount bushings basically rot away, and so does the fuel tank strainer at the bottom of the pick up tube inside the tank. My 2008 w/6.4L truck has had to be towed back to my driveway like 3 times this year already I'm sick of the blasted thing! We're getting rid of this thing just as fast as we can find some sucker with more dollars than sense! Ford POS! Meh! 😕
@Michael Shrader good luck finding a truck with body bushings that don't degade after 15 years of hard work. Why didn't you get the tank fixed after the 1st tow? Sounds like you have a maintenance issue
Unfortunately for the Powerstroke generations during the emissions changes for the 6.0l and the 6.4l Ford had some issues. Then everyone is going to compare the 6.0l/6.4l to the 7.3l. The 7.3l is considered by Ford diesel truck enthusiasts a million mile motor. The only issue I have with the 7.3l is the low HP and low torque is factory form.
Been working around Diesel engines for quite a few years I can tell you that the 6.4 is my least liked engine in a pickup period. Most of the issues we have seen with these engines go back to the fuel system being poorly designed. While doing proper maintenance does help keep these engines alive it is definitely not the definite answer. The injection pump itself on these engines like to fail without really any warning sending metal through the fuel system and plugging up the injectors, and in some cases causing the injectors to hang open and send high pressure fuel into the cylinder when it’s not suppose this cracking the pistons due to excessive high pressure around the piston lip and causing extremely high EGTs. I personally think if a person could find a way to put a CP3 high pressure pump on one of these engines along with an aftermarket lift pump filter action system it would make it way more reliable and possibly even desirable since these trucks, when they run, run very well with the right tuning. But unless somebody comes up with a different high pressure fuel pump option for these engines I will continue to advise my customers to stay away from this engine, enough so that I recommend a 6.0 over the 6.4, just my opinion.
Sounds like the Duramax problem.
Belt drive cp3?
my 6.4 is factory 2008 not deleted, not tuned. runs perfect. i love it. it has all the power i need. i do regular maintenance on the vehicle. i did add a coolant filter and i change it every 6months. maintenance is the key. also, on turbocharged diesel engines you should always pre warm the exhaust and also cool the exhaust when you get to your destination. i have an exhaust monitor on my radio and i've seen temps when pulling loads when arriving at destinations reach over 750 f. this can cause warping, hot spots where coolant will start to boil, and oil will coke on the turbine shafts. over time it can cut the bearings and seals out of turbo chargers and other engine components as well. i do want to change that one part for the oil blow by though. my truck has 144K miles on it at the moment, and it has no problems with it.
I'm not a big Ford person when Powerstrokehelp says he's done with the 6.4l I take that as a sign
I received one of the first 5000 6.4 F550s produced in 2008, I had a mechanic body with welder, crane, lube skid and air compressor. Empty the truck was 15,800 lbs. I put 100k miles on in two years on the severe duty maintenance schedule. The only problem I had? A clogged primary fuel filter when our dealership didn’t know to change it. Literally problem free. It was a lease vehicle, and we could not do any maintenance our selves per our lease contract. Every problem I ever heard of could be directly related to a lack of maintenance, improper maintenance, or illegal/unauthorized modifications. Unless you’re going exclusively off-road with any engine since 1996, leave it stock. Best chance for longevity and durability.
Agree w sever maintenance schedule and keep up all components, I hope that will prolong when the ticking bomb actually set off.
The head bolts I upgraded to ARP head studs and o-ringed my heads so I could run up to 300 HP tune if I wanted to. The fuel I would recommend upgrading to a Fass 165 GPH lift pump because not only does it do better than the stock lift pump but the filtration is better. I also added another water separation filter between the Fass and engine.
Doesn't matter what you do to it. It's always gonna be a piece of crap.
@@nathan40307 That's a matter of opinion. But once the issues that Ford and Navistar didn't fix are addressed and/or upgraded it's a hell of a engine. That's why with nothing but a tune on these trucks they can run off and leave the majority of semi upgraded trucks. With the problematic parts swapped or upgraded these things can make a lot of power. Maintenance is key also, plus you gotta pay to play because this platform isn't cheap either. One big thing that makes them look bad is alot of people and younger kids get one and throw a 300 HP tune on a stock truck and drive it like a race car every time they pull out and once something goes back then "It's a junk engine*.
Wow I knew these 6.4 were trouble I had no idea they had this many problems. The real problem is the EPA all this emissions crap. The construction company i work for is having problems with new dump trucks with these DPF systems so its not just pickup trucks. good video
Love my 6.4l. STUPID PEOPLE DO STUPID THINGS. ITS NOT A RACE CAR.! Delete and Maintenance is the answer !
Proper maintenance definitely seems like the key to extending the life of the 6.4L!
Exactly that’s exactly what I’ve done with my 6.4 and it runs like a son of a bitch real workhorse!!
This myth is why people keep buying broken 6.4's. They're junk, bud. No amount of work changes that. Plenty of deleted and babied 6.4's with glory hole-d pistons
@@backwoodsbuildingandfixing9223 at one point they all fuck up but this one has not we don’t run the hell out of it and it’s driven regularly with regular maintenance! Is it a bad design probably ! I’ve had this one for six years now , and Very few issues and it could take a shit tomorrow !
I'm almost at 100k on my 2017 3500 Duramax and tow a trailer every single day except during the winter time it's got a 9' plow blade on the front and 3.5 ton bin of salt/chat with spreader in the bed. Its constantly running probably 14--16 hrs a day and as someone who's not been brand loyal in the past (I prefer value, reliability and least amount of ownership costs)but bc I need a 4 door truck I'm pretty much forced to choose from the big 3 Gm,Ford, Dodge..have owned them all but have had zero problems with my current rig. Just maintenance cost so far..im shocked bc it's had a hard life thus far. Had good luck with Cummins Dodge trucks but went through 3 trannys due to my work and the mountains I live amongst. Loved the 7.3 Ford and had 2 back to back then they got rid of for the 6leaker garbage.
Thanks for the imput that had nothing to do with the 6.4.
6.4 good for power. It's reliable if you maintain it and keep an eye on oil level. (Not sure why the fuel manifold is covered by the valve cover because if there's ever leak you won't see it except your oil level will increase.)
I just rebuilt one and they are expensive. You have to get rid of all the junk stock parts. (EGR, front cover, hpfp, lift pump, head bolts, pistons).
6" lift with 12.5x35 getting 15L/100km and 14L/100km highway. Not bad.
between the internal fuel system and shitty timing cover/water pump design, i learned to NEVER expect 15 quarts out of a 6.4. i simply don't enjoy mopping the floor that much. Ever get the counterweights slapping the oil so much that the customer thinks its got a miss? ...only to drain 30 or so quarts of fuel oil out of the POS...
I’m just helping you out understanding the egr.. The egr recirculate exhaust gasses not to be reburned but to lower combustion temps to reduce nox output.. higher combustion temps causes more nox output so the small traces of exhaust gases displaces the oxygen which creates lower cylinder temps to reduce nox output
1) Hpfp also leak fuel straight into the engine oil and there is no fix or delete for that.
2) exhaust manifold bolts break off in heads
3) rocker arms break
4) injectors go bad and fuel knock which takes out doc and dpf
5) hpfp harness rubs on pump housing which u have tare the engine apart to replace it.
Just a bad engine threw and threw. Make the 6.0 look like a great engine.
Facts. This comment needs to be at the top
I finly finished my and instaled my catch can. Its large 4X7" with 1" ID tubing its baffeld and packed with SS pot scrubbers. I biilt it out of PVC pipe to allow. Space for the vapors to settle and the SS knitted mesh will give the oil and other particles somthing to cling to be fore the air presure leaves the can. I also put a 3/8" ball check drain on the bottom. To drain at your 5K oil and filters change. PS I will never run my Catch Can vent back into my post air filterd cold air intake. Untill I can find a better solution the Can will vent to you got it atmosphere. At least it is filterd any particles that make it through will quickly fall to the ground. Or paved road. (Oil based road)
Now that you covered everything about the 6.4, can you do the 5.7 olds diesel the came into GM cars in the late 70's?
I’ve looked at them and seen some really nice looking clean trucks for cheap. But now I know why!
As someone that worked as a MD diesel tech for 18 years, you are all welcome to say what you want, but there is a reason by 2010, alot of shops just refused to work on 6.4s. You will never be able to pay me anything to work/build/look at one ever again. I saw so many people properly take care of these, pay top dollar to delete, stud, head job, you name it and it just explode within a year. This engine single handedly helped mainstreamed the fummins swap. I don't even know where to start with it, its just crap, a boat anchor, i bad one at that. You can at least delete/stud a 6.0 and it go over 300K no issue, a 6.4 completely done up, maybe next year, maybe tomorrow, who knows. Its like driving a car with a CVT, you're not just watching the road ahead, you're watching the road ahead 247 to see where you can pull over safely when it breaks down. If you own one that made it a while, you are one of the ultra rare lucky ones because most didn't get that experience.
My 08 6.4 just clocked over 230,000 miles it was only deleted at 225,000. Ig that truck is an ultra lucky one.
Completely agree, I'm scared to even take one in for other stuff because I don't trust the engine won't blow apart while pulling it in and out of the shop. They are such a shitty engine.
@@brettpatterson8641 Hmmmmmm an 08........ an 08....... 230K that only got Dd at 225K, not gonna lie, that's the most SUS thing i've read on hear in a very long time, i hope the best for you friend, but i just don't know about that. A 10 Dd at 50K or below and some major stuff around 100 and 200K yeah ok i can see it, but a 08, somethings fishy here, at minimum stage2 at some point or 10 or SSP swap.
Ford five hundred would be an exception to the cvt rule
A day shift worker ran one out of oil. The 6.4 litre Powerstroke normally takes 15 quarts of 15W40 oil. The user of the ute deposited the vehicle into the fleet service area. I took the vehicle in and found it had only 3 quarts of oil in it. The twin turbo had spun the bearing horribly and destroyed it. Since I was in there, I got rid of all the worthless American garbage that makes it use double the diesel, make half the power, and clog all the valves. I put a new twin turbo on it change a few weak looking electrical harnesses, and rehoned the cylinder walls. I replaced the cylinder heads with aftermarket cylinder heads, for the fun of it because it was such a slow maintenance month on that cold Canadian winter. After it was all repaired and running wonderfully, work decided to auction it in the company's yearly vehicle disposal auction where ruined cars, vehicles with very high odometer readings, vehicles that were bought for seeing how they do in our fleet do but failed because of reliabilty, quality, range, durability, go. I went to go make an attempt on the old F-250 Super Duty. Among a large amount of Nissans, four cylinder Chevrolet 1500 junk piles, a few ridiculous Teslas that were bought to see if they could serve as sells fleet vehicles, I found the old F-250 Super Crew 4x4. Since most of Northern Canada was locked in an ice age, there were few people there, to buy used fleet vehicles. The odometer on the F-250 had 1.528.500 kilometers so little interest was taken in it. I got it for $500! Ten years later, I still have the 2010 F-250 Super Duty Super Crew 4x4 with no issues at all. Fuel is extremely cheap so it runs for almost nothing. Ripping all the stupid American environmental garbage and watching oil level is all that is needed to keep the engine running great. But, how does someone run out a 15 quart sump?
6.4 was a great engine if deleted and turned power is awesome and fuel mpg are great
Deleted ones cracked pistons more often than stock ones lol. Everything about them is junk.
These things are fuel hogs, the only way you get great fuel mileage is if the lift pump dies. The HPFP won't be far behind then. I definitely did see decent fuel mileage before the HPFP started seizing up, though
@@Redsfanatic32 that’s because most people run the hottest tunes they can get. Put a 300hp tune on a stock engine it’s not gonna last long.
@@tommybragalone7943 all the ones I’ve seen have been really conservative tunes. Piston design on them is junk. They crack pistons at stock power with stock equipment and crack them deleted on stock tuning all the same. You can’t point fingers when it’s a junk design from the beginning
2 things, if you’re just installing head studs the cab doesn’t have to come off. Diesel power magazine did an article that outlined how to remove and lower the engine mount for the passenger side if I remember correctly so the studs can be sneaked in. And if you forget to use anti-gel in your fuel that’s a 3rd way to cause the k16 to fail as I learned the hard way.
Yes it can technically be done with the cab on, but from what I've seen, most people choose to remove the cab to make it easier.
385k miles on mine. No problems with anything other than replacement of rear brake calipers, and a brake job, and bearings in the front.
So far we had ours for eight years not one problem, here’s a joke, the one problem we did have we just had to go get some Diesel, that’s the Harshest probably ever had lol
Love my 7.3 power stroke I'll sacrifice a little power for a dependable engine have spent very little money on it or my 7.3 idi
I have a 2008 6.4 F350. Other than complete preventative maintenance, with quality parts and fluids, and drive like a sane person, never had a problem. 167,000 miles and paid off 9 years ago.
