Tearing Down A Ford 6.4L Powerstroke Diesel "Core" Engine. A Pricey Core, But How Did I Fare?

I KNOW. It took a while, but FINALLY, a Powerstroke! You would think with as notoriously unreliable as these engines are they would be everywhere but it took a bit of effort to get one. This was the one to have too!
If you're new to the channel, my name is Eric and I own and run a full service auto salvage business called Importapart. If you're looking to buy parts you can visit www.Importapart.com and fill out the part request page if you don't see what you need, or you can shoot us an email at [e-mail].
Part of our model is parting out core or blown engines. A core engine by definition is a bad engine, or someones old engine that they have replaced. We cycle through hundreds of these every year and I teardown one on camera every week! There are over 80 teardowns on this channel, everything from Viper engines to a subaru boxer, Cummins to Duramax, and lots more.
As always, I appreciate all of the comments, feedback and even the criticism.

As a powerstroke tech maybe I can shed some light. The 6.4 has a bad reputation because of the emissions. The process of regeneration kills the engines. Regeneration isn't done through a 9th injector like the duramax motors so it is done as a "controlled" over fueling. The problem is the trucks never completed regen because of city stop and go driving, or a bad air filter, or a sensor bias, derate etc etc. So the trucks stay in regen constantly which is hard on the motor. Eventually that fuel works its way into the motor and then you're lubricating the engine with diesel fuel. They typically burn piston rings (because of the overfueling) and throw lifters because of the poor lubrication. It isn't uncommon to drain twice as much oil out of them because the oil is diluted by fuel. Deleting them increases their lifespan substantially. If that isn't an option, then use quality filters, fix your check engine lights, look out for black tail pipes (means the dpf is cracked), and check your oil regularly to ensure it isn't over full.

Thank you for sharing this with me. I am a fleet mechanic for a public utility in California. My service area is the high desert in San Bernardino and Inyo counties to the Nevada border. This includes Death Valley. This blistering hot, dusty terrain can put any vehicle to the test. Most of the fleet I deal with are larger Navistar trucks with manlifts and digger derricks. But I also service about eight F550s. In 2009, they replaced the older F450s that had the 7.3 with the new F550 with a 6.4. I was told this was a much better engine. That was odd because I didn't have many problems with the 7.3. Almost immediately two of the trucks hand-grenaded the engine. Ford covered the engine under warranty but I had to do the work because they couldn't take off the cab. The trucks had a boom hanging over the cab. Since the truck couldn't start and run the PTO, the boom couldn't be rotated out of the way. I replaced both engines with the cab on. After that, Ford refused to cover the engines under warranty. They argued the trucks were too heavy for that engine. The trucks weighed about 17,000 pounds. Over the next 10 years we had the F550s, I replaced seven engines, about a dozen turbos, High Pressure Pumps, Injectors, all with the cab on. I can't begin to tell you how much money that cost the company. And I am only one of 43 garages in the company. With the exception of the DPFs, Ford refused to warranty almost any other failures. When the cab and chassis were purchased, I am wondering if Ford knew ahead of time how heavy the finished trucks would be. Nonetheless, we no longer have any 6.4s. I always wanted to take one apart. I always replaced the engine for the sake of time. A truck out of service leaves a crew unable to work. I wanted to take apart a core to see what happened but I simply didn't have the time or space. I would have gladly given them to you if I had known you. I am glad you made this video. Now I finally get to see what one looks like inside.

I am somewhat of a 6.4 mechanic, once "built" properly these are actually marvelous engines. There are quite a number of factory "flaws", especially with the valvetrain and heads. The factory cam is designed for EGR, swapping to aftermarket, is known to make the valvetrain survive longer. Premature rocker and lifter wear is very common on a factory motor. Emissions delete is a must if you want the engine to survive. Factory cast pistons are known to crack on some engines as well. Properly built, these engines are a true monsters

[@michaelchan8915]

That was a walk through memory lane for me. Back when trucks with these engines were coming to dealership for work while they were still within warranty, I had LOTS of these garbage 6.4 engines apart. The failed roller lifter and damaged cam lobe is exactly why that engine ended up in your hands. Just the cost of the labour, along with the cost of all the gaskets needed to cam and lifter that engine would have either matched or exceeded the cost to outright long block the truck it came. Of course, given choice between the two, it would have been a no brainer to go with the latter of the two. As you already mentioned from the beginning of the video, cam and lifter failure were very common on these engines. On the ones coming in still within warranty, with this exact failure would have resulted in a long block replacement as already mentioned. Other common items on these engines were prematurely worn out rocker arm tips, cracked pistons from overfueling injectors as well as cavitated water pump housings on the engine front cover. A replacement front cover will have a divot in the six o'clock location of the water pump housing to mitigate a repeat of this type of failure, so it's probably not worth trying salvage and resell that front cover. BTW, the method you removed the cam from this engine is incorrect. The adapter you removed from the rear of crank to gain access to the cam gear is not supposed to be removed. This is why I used to call those six bolts the "DO NOT F*** WITH" bolts. The crank is machined from factory with that adapter bolted to it. By removing that adapter, you've essentially junked that crank, not that it matters. To access and remove the cam requires piston and rod removal, along with crank removal. So as you can imagine, the labour cost along with all the gaskets, along with the cam and lifters themselves is what made long block replacement the more cost effective route.

There are aftermarket camshafts available that have a much smoother ramp profile on the cam lobes vs OEM. The smother ramp profiles makes them much friendlier to the lifters and rocker arms. Contrary to much of what you hear, out of fear, I tore down my 6.4 after 340,000 miles. Before it had a chance to come apart. Only 2 cylinders measured out of factory tolerances and most of the bearings and engine internals looked great. 340,000 miles, with all original internals and original injectors/ pump. This motor had regular 5k oil changes and was EGR / DPF deleted since around 60k. I installed a new smooth profile camshaft and de-lipped MaxForce pistons for assurance. Looking for another 300k.

The water pump housing on the front cover has issues where cavitation (tiny bubbles exploding due to impeller speed) erodes the pump housing. Ford released a coolant additive that helps to reduce or eliminate it, but if you never knew about it, doesn't do ya much good.

[@keithcannon3682]

My understanding is the factory clearances for the back of the water pump to rear wall was off. Most of the early 6.4's were like this. No...it is not rare or unusual. If you get ahold of an early water pump and do a rebuild you better check to see if the impeller even moves. I have heard tell of builders having to pull an engine back out for this very thing. The water pump on there is not oem for an early 6.4. Wondering how much you want for that studded 6.4 you have. I was going to do a build on mine but if the price is right....

[@mikeworkman3593]

Everyone knows what cavitation is. If they don't then they have know business asking what is means. All diesels are prone to it, due to the high compression, the liners(wet liner blocks) can flex and cause pitting and failure.

[@Bacongrease00]

6.4 has a beefy bottom end, sometimes the pistons crack, the lifter failure on 6.0 and 6.4 is fairly common. The lifter is used in other engines but on 6.0/6.4 one lifter gets the load of two valves. Always replace lifters if you pull the engine. After 250-300k it’s a gamble. I think it was under engineered. 7.3 did not have 4 valve per cylinder. Check the oil pump section of the cover. They get scored up pretty bad due to tight tolerances.

Either from lack of maintenance or "tuning" (I use that work VERY loosely, just turning up the boost and fuel for maximum smoke production doesn't really qualify as tuning, but that is what most diesel owners do). That said, the "small" failures that these engines have (or really any modern diesel) cost literally thousands of dollars.

Erosion of the pump impeller from cavitation is technically due to insufficient "net positive suction head". The pressure at the inlet of the pump falls so low that the fluid will flash into vapor (steam). This can occur at room temperature and will happen more easily at higher temperatures and with changes in specific gravity of the fluid used. Of course this means virtually nothing to you but the terminology sounds so dirty I couldn't resist writing a comment.

All of internationals motors took a major downturn in the early 2000s after the 7.3 (my main truck has one) was fantastic after that the reliability only went down fast, same with the Maxxforce series

Wow...plastic rocker retainers. You'd think that the entire world would have learned with the old early 90's Buick 3.8L V6 that this was a bad idea. Apparently not.

[@dwayneelders9523]

The rockers pivot on a large ball bearing. The retainers hold the assembly together when installing it. Really don’t need them once installed and the push rod is holding pressure against them. But when the lifter ground and became shorter, the ball probably fell out and the plastic broke. Just fyi. Later.

[@jeffryblackmon4846]

This is an interesting tear-down. Thanks for the video. When I saw your 1/2 inch breaker bar start to bend, I knew those were some very tight bolts. Why don't you use an engine hoist or that fork truck to pick up those heavy parts? Take it from someone who's had back surgery and now has titanium bars on my spine, your spine isn't meant for heavy lifting. I learned the hard way.

Other than that cam and lifter this was a solid core. If it was mine it would've gotten a new cam and lifters when it failed and then put back into service. He probably made out well on this one honestly.

[@brody4886]

Generally the problem with these is not the oil pickup clogging they dilute the oil with diesel to the point where they begin to take out top end components and eat the rocker arms

[@brody4886]

They have lots more issues than that basically all the issues that the 6.0 had they just replaced the problematic HEUI system with an even more problematic common rail system and added an oil dilution issue

Finally! I'm so excited. I don't even own one but I'll enjoy this. I've driven them all...7.3, 6.0, 6.4 and 6.7. I should've known that the "six four" would be the easiest core to find. Anyways I'm comfortable now and pressing ▶️! 🍿

[@robm3357]

I have herd the 6.4 horror stories also. But looking at you take it apart it looks well built. The failed lifter roller was an unfortunate issue for that engine.

[@magnusbrachat6256]

im maybe the most far away viewer (germany) of your videos and i really like them. they are based on facts, great to see the tear down, and your logic on the reasons for failure make most of the time a lot of sense to me, and im not a engine or car guy. I learn a lot here and really appriceate the time to take for this taredowns and analysis of this interesting engines. Thanks a lot. Grat achivements.

[@davidbuechler6172]

Hello Eric from central valley CA. New to your comment section. Watched almost all of the teardown videos. I really do enjoy them. Being an old school gearhead with all the tools to do mechanical work. But also the old body that has the wear like the engines you pull apart. Can't say I'm ready for the body farm. Brings me to why I'm sending this. Lifting the crank of the 6.4 power stroke diesel the way you did. You will have a back like one of them 3 angle rods you have found. ( Those are very impressive by the way ). If you keep one on the wall or counter at the yard. Look at it to get a reference of the future!! Mine is getting a maintenence job in the very near future. The powerstroke water pump housing has same markings as a pool pump. Replaced impellers on mine but never a housing. Unless the housing cracked or melted. Again, I enjoy the chanmel.

[@noahpelletier3871]

Pretty insane how much plastic is present in this engine. Also four bolts per cylinder is surprising too.

[@jeremymcauliff8485]

My parents had a 6.4 in their F450. Constant problems while they owned it with overheating and going into limp mode. It went to different shops but never got figured out. Driving empty or lightly loaded was fine. Hook it up to a 14k travel trailer and it would go into limp mode after about 1 hour of drive time. Limp mode and a 14k travel trailer is no fun.

[@dannywhisnant8845]

Fifteen years ago I was given a 95 Escort (1.8L manual). It had a bad knock/rattle. Lifter roller had turned sideways and broke the retainer. Lifter looked just like the failed one here, flat on the roller. Cam was scratched but serviceable. After replacing the lifter and retainer, I drove the car for 50k miles before selling it. Lifter failure happened when previous owner over-revved the engine by going into 1st gear instead of 3rd on a freeway exit. Love your content!

@33:35 I'm an IT guy, and back in the day a buddy of mine in our computer technical support shop managed to plug one of those allegedly "idiot proof" D-shaped power plugs BACKWARDS into a 250 GB hard drive, which back then was worth $250, 1:1 dollar to gig. (Mostly) he and I (suppressing laughter) watched in horror as the core of the Texas Instruments DSP chip on the drive's circuitboard turned a starry bright white as the magic smoke fled from its circuitry bonds into the ether.

The cleaner pistons can be from a small head gasket leak--- the coolant will steam clean the piston.

Yes, that's what happens on the 6.oh when the EGR cooler fails.

Most neglected nissans are the volume cars and the 2.5s. the 2.0 vc turbo are in Infinitis and the altima vc turbo which are pretty rare. ive also witnessed one lock up in under 30k miles and it was the elderly couple's second engine.

[@elGamiReal]

Given how new they are and high failure rates i doubt he'll have easy access to one since the dealers might get them first

[@g1channel]

Use a razor or a wire wheel to get the carbon off the cylinder walls at the too of the bores. Helps out alot with getting pistons out.

[@gregoryweber7408]

thanks again for investing that much time in a tear down, it always amazes me how filthy diesel engines get after being used, and thank you again for the lesson in component failure and the carnage it causes

[@Duken4evr29]

Remove EGR from the equation and diesels are much cleaner running than what we have here.

[@davekimbler2308]

my 2 cents worth .... i own a 6.4 and its truly a beast ( nothing on the road can beat it around here ! i deleted the DPF and EGR and installed a S and S tuner , i have driven diesels all my life and this one feels like a sports car that weights 4 ton. i intend on rebuilding it at or around the 250,000 area !

[@Thedoug369]

Only problem is that 6.4s really can't be rebuilt. Once you get it apart you'll quickly see that not much is good and parts super expensive for these engines. They were basically designed to be 150k throw away engines. You can buy a complete replacement crate engine from Ford for around $17k, but the kicker is that if you delete it which is the only way they will last, Ford won't warranty it if it breaks ( which it probably won't actually if you're good on the fluid changes.)

[@fascistpedant758]

I recommend that you get a second pry bar and pry both sides of what you're trying to remove. Most of what you spend time moving from side to side on would come out much faster if you would pull them out straight. Great videos! Thanks.

I want to see one of those too. I'm scared for you about the oil pump belts on your 3.0L diesel though...my dad has a Ford 1.0L EcoBoom with the same problem. Hopefully there's a retrofit from somewhere that allows you to put a chain on there or something

The egr system ends up turning the oil into soot, so the oil quits being oil and turns into a soot / oil mixture and doesnt lubricate very well
