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.

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.

[@michaelchan8915]

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.

[@nellyfarnsworth7381]

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.

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.

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.

[@jimmysturdevant9843]

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.

[@adamturner2507]

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

[@patrickmcguire3673]

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?

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?

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.

[@KevinJames-yg9eu]

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 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.

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.

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.
