700,000 Mile 7.3 Powerstroke Teardown! Does This REALLY Have This Many Miles?

[@joebartolomucci8870]

This is awesome. That was my fathers truck. He owned a plumbing business and commuted over 100+mile a day since he purchased it new. The only engine work that was ever performed was new injectors due to the fact they thru him the keys and never owning a diesel before didn’t know about the lever to empty the water from the fuel. It also had the oil pan and oil cooler changed. The Trans and front end was rebuilt once. The straps broke and dropped the gas tank on the e way once but other than cam sensors it was very reliable. The maintenance was done religiously with Rotella. My Dad passé two years ago. And man would he have loved to have seen this!!!!

[@joebartolomucci8870]

Also the cluster went out about 2 years before the wreck so I would guess the true miles as closer to 800,000/850,000

[@joebartolomucci8870]

Also once when it was having trouble starting a knucklehead lumbaryard mechanic used ether which is what probably damaged the piston.

​@@joebartolomucci8870This is really awesome ! Sorry about your Dad. He is absolutely right, cheap oil, expensive engine. You pick which one you want to replace. I think I'll change the oil. So much cheaper ! That's just awesome he got over 700,000 k miles on that old 7.3l Built Ford Tough !!!

[@daciefusjones8128]

my 97 has had rotella in it since 97. I was a truck driver and owner operator also and I always had rotella in all of them. A guy I worked for in 1974 and his mechanic showed me why I should too. they both had 40+ years in the business and knew their stuff.

[@theupscriber65]

I was a manufacturing engineer on this motor. It appears to be pre-1999. The valve has a 1998 date stanp. The injectors were often replaced by the factory on the two rear passenger side cylinders because of customer complaints for noise. We sometimes used the marine injector. If the cam is original it's also pre-2000. We switched from an induction heat treat that did one lobe at a time and left that blue circle to one from Contour Hardening that treated the entire cam at once. I also noticed the shaft diameter has some severe chatter during the plunge turning operation (Op20) done on a specialized machine from a company called Crankshaft machine. Lastly the rods look to be the old 4130 forged rods with milled mating faces. Later models used powdered forged cracked rods. Most forged rods were made in Indianapolis, but several thousand were made by Kaiser Manufacturing in Germany while we transitioned to powdered forged rods. Those will habe a K stamped on the weight pad on the end of the rod cap. We did have some premature cam and litter failures because the lifter supplier didn't properly heat treat the roller tip but not many. It looks like a high mileage engine.

Man, does that bring back memories. My first job as a mechanic, back in 2001, was in a shop that had the service contract on all the ambulances in that region (South shore of Montreal). And they all had 7.3's. Everything you did, with the exception of cam and crank removal, I have done on these engines. (We had a special tool to remove the injectors). And let me tell you something...if you think removing the heads was tough, try doing it in the enclosed space of the engine compartment of an E 350. That was one hell of a job. Now, in the shop where I work, word has gotten around that I have years of experience on the 7.3, so we have several customers who show up with their F350's because no one wants to touch them. To me, they're old buddies...always enjoy working on them for old times' sake.

@mausball - Mate, you are dead on. I have done several off high mileage seven3’s and with proper maintainance - they look like this engine.

The 4E (T444E - we just called them 4E's to differentiate from the old iDi 7.3) could definitely take a flogging and still get you there and all the way back.. They really were the Accord/Camry of diesels. Only 2 real ways I ever knew to genuinely hurt it was either running low on oil for way too long, or a lot of water through the injection system, and that was about it. The old iDi was really good too but had 1 or 2 things to watch out for that the 4E really didn't have. Lack of turbo on the old iDi made it a sh*t show pulling trailers uphill

This engine looks like it was worked hard but was also very well cared for. The uniform wear on the crankshaft journals, the cross-hatching still in the bores, the cleanliness of the aluminum front cover, the general cleanliness of the inside of the engine all suggest frequent oil changes using good quality oil and filters. I believe this is a 700,000 mile engine without a lot of idle hours. If was and idler and not a workhorse, you wouldn't see that type of wear on the crankshaft journals. This shows again what my Grandpa said: If you take good care of your equipment, it'll take good care of you.

[@iamthemoss]

I have a 1996 F350 flatbed. I bought from a friend of mine who owns a diesel shop. He got the truck basically from a customer who ruined the motor. He replaced the motor (it was rebuilt by a shop in Cullman) and he put in a remanufactured E4OD transmission at 190K miles. I've had it for a few years. I love the truck, I use it but not abuse it, I don't have a business just some acreage. I have people ask me all of the time to buy it. I've only put about 15K miles on since I had it for 4 years. It should last me the rest of my life. It has such a sweet sound. I need to get the AC fixed.

I agree with your assessment. The truck was probably on a strict service interval and they were driving the wheels off the thing.

One borke 700k last October but in its last service showed to have copper and other metal's in the results of its last test. So its a yard and parts running truck now. All have very high idle times being we live in the mountains of Colorado. All pulled Bobcats skids and mini excavators. The other trucks are doing fine and are in the 600k range.

My 2003 7.3 powerstroke had over 600,000 km (400,000 mi.) It was the cleanest engine inside that I had ever worked on. Couldn't get a white rag dirty wiping inside the valve covers with solvent. 7.3s had no EGR to pump pollution into the block or intake stream. Also it's best to run good old conventional oils as the detergents keep the soot in suspension and drop it out with each oil change. They also cannot be run low on oil as below 9 quarts in the pan there isn't enough oil to feed the HPOP, so they simply will not fire.

[@screener545]

If your HPO res doesnt fill, you have no LPO either. You are still cranking dry.

[@averyalexander2303]

@@screener545 Without the injectors firing, there won't be any combustion, so there will be no load, minimal heat, and not much stress on the internals. An engine will survive a LOT longer without oil pressure when being spun externally such as from being in gear or cranking than it will under an actual load. Considering the fact that engines can idle for hours and drive for 20+ minutes under load with no oil before failing, odds are good that if there was a total oil loss, just the residual oil left on the moving parts will protect them for the perhaps 30 seconds of 'run" time it might take the driver to pull over when the engine cuts out. An engine running under its own power is COMPLETELY different than being spun externally with no fuel supply and the oil film won't disappear as soon as oil pressure is lost.

[@elliotkane4443]

The fact that the HPOP won't make pressure for the injectors if the oil level is low is such a maintenance dream, these engines are really great.

That's a high-mile workhorse. My '95 F-350 has 645,000 miles on it now and aside from a set of injectors, two sets of valve cover gaskets, three water pumps, an alternator, and a set of glow plugs has never been apart. Even the turbo's original. I've run Chevron Delo 15w-40 and NAPA Gold filters on 6,000-mile intervals since it was new and you could still eat cereal out of the valve covers. It's that clean inside.

[@randr10]

I can believe it's a 700k mile engine. If it was a reman deal, at least 300K+ on it with that bearing and lifter wear. The crosshatching still being on those cylinders is a testament to how far lubrication engineering has come in the last 50 years. It used to be that 200k was considered an insanely high number to get out of an engine outside of something like a semi truck. Now we're seeing this engine might actually have 700k on it without any internal work needed. That's a damn impressive number. Something to note is that this was in a pickup and is an engine designed for a medium duty application (Think ~10-12k unladen weight, 18-26k loaded), so it's had a relatively easy life as far as load goes. Let's not forget about engineering. This was probably one of the last engines at International designed and built by the older generation who had the concept of quality (things like TQM) coursing through their veins from top of management down to the lowest guy on the totem pole, with some advancement in modern tech thrown in to spice things up. They way overbuilt it for the stock power level. Very similar to the engineering and manufacturing coming out of Japan in the '80s through early '00s (Toyota and Honda mainly). Their thought processes were in decades, not quarters, and it shows here. You can also see how that got thrown out the window with the 6.0L and 6.4L engines that followed this one. They were a disaster by comparison. The crazy thing is how much they had in common with the 7.3L, but they still managed to screw it up. I don't know anything about the corporate structure or management history at IH, but my guess is that there was a generational shift change that happened right around the time the 7.3 was being phased out. You need to have everyone in the organization knowledgeable about engineering (at least from a layman's perspective) to get quality products like this. Good engineers can't make high quality products by themselves. They need good management backing them up and the manufacturing side needs to be on point too.

Very much enjoyed. Thanks. I won't let go of my 1996 f350 7.3 even though hardly use it no more. 1996 with 98500 miles actual odo. Only issue is small rear main seal leak (mechanic in bottle not really helping) but its real slow leak only when running and hot.

[@brendawernicke7663]

Are you sure its not leaking down from the turbo pedestal? There is a drain hole in the block to let liquids run down behind the flywheel or flex plate.

[@fogeyes]

@@brendawernicke7663 Well It seems dry up there but wet at rear of engine. But I;ll take a closer look tomorrow. Thanks

[@snoopytheace4487]

@@fogeyes if that mechanic in bottle is a stop leak for the oil, expect to have a lot of oil leaks. I've seen people use that stuff and I usually end up replacing every oil seal on the engine.

@@snoopytheace4487 Oops! i put three 16 oz bottles in it 1000 miles ago. i used Bar's Leaks Rear Main Seal Repair, after oil change. Guess I'll change oil again. Thanks.

I love the way the 7.3 starts up. It has a growl like no other.

[@starkindustries26]

They will run with a cracked piston it will just push all that compression into the crankcase. Love the vid and I would totally get that as a builder if I was local. I have 2 7.3 powered trucks and they both have 250k+ and still run great

[@Demonlord468]

I have a 7.3L in a 1995 Super duty service truck with an IMT truck body and crane that 10K short of rolling over 400K and it still runs like a clock. Those engines are legendary for their reliability and ability to break well over a half millions miles without a sweat just as long as you keep the oil changed pretty much. Oil changes being the most important of all since it not only protects the engine but also all the parts in and around the fuel system including the injectors all of which are very expensive if any of them fail. And bad oil is what causes failures in the HPOP System on those engines the majority of the time.

[@kathreyburn7012]

I really like the longer, more in depth videos. Thanks for this one.

A brother saint Louisan. I wish I was much younger, to do those type things again, I would love to visit your shop at some point in time, to watch you tear down any newer motor. I'm not into newer motors, I'm an old school gearhead.

[@mobileu47]

Mine had lots of blow by is why I rebuilt it. Piston #5 has pieces fall off when it came out and #7 the compression ring land was deformed downward angle. Still fired up and ran everyday. E99 has AB code injectors a few CC's smaller than L99 which arr AD code. 94-01 73's are more desirable cause they have forged rods.... L99 has PMR rods.

The idea of a video and a “builder’s package” is a great idea. It would answer a lot of questions for the buyer.

[@t-yoonit]

Filling those cylinders with oil is common even when doing glow plugs. When we did my brother in law's 7.3 glow plugs I used a spray bottle sprayer with a long hose added on to evacuate the fluid to avoid hydrolocking it. We used the same trick a few years later to get all the oil out of a snow plow pump reservoir that had a stripped drain plug.

[@SurelyYewJest]

Safety third! Disregard if they were already tilted, but you're killing me with the forklift. Tilt the forks back a bit toward the cab so that if ish goes south, the chain and engine slide toward the middle of the machine rather than them surprise falling off the fork.

[@areitu]

I always save the longer videos as a Sunday morning watch activity and don’t mind at all! The hairline crack in the bore at 45:18 might be an indication of cavitation pitting the cylinder liner from the cooling jacket. It can happen with on any diesel engine (especially with the non turbo 7.3 IDI) if the additive levels in the coolant aren’t properly checked and maintained over its lifetime. From what I understand it may be repairable by boring out the cylinder and pressing in a new sleeve Disclaimer: I own a truck with the non PS 7.3 IDI but I am not a professional tech so I’m armchair guessing and defer to people who do work with the PS 7.3 if I’m wrong about anything

[@honkhonkler7732]

That was more a problem on the IDI than the PS. They're completely different engines of the same displacement.

[@Ghauster]

We had over 400k on an 88 non-powerstroke 7.3. It still ran good. Transmission was never apart. We did put head gaskets in at about 300k. Clutch was about every 4 years. Rarely because the clutch was bad but the clutch plate would rust up and destroy the throw-out cylinder. After 20 years of great service. We gave up trying to keep the body together. Used it as a farm truck for a couple more years and then sent it to scrap.

[@Val-xi4we]

2003 7.3L with 445k miles here. owned since 40k miles. Never had the valve covers off. Only major component replaced is the turbo at 400k miles and it was not because the turbo was bad. I just was not putting a 400k mile part back on when I was fixing a oil leak. Still running original ECM, original injectors, original HPOP, original glow plugs, original transmission. Obviously things like the water pump, alternator, starter have been replaced but those are wear parts. oil changed every 5k and trans fluid drained and topped off every 30k with full pan drop and filter every ~100k.

[@ChuckKarl525]

very nice! I am on my third diesel truck, two of which were purchased new. I rebuilt my '86 6.9 liter that had less than 100,000 miles on it. Fairbanks cold starts with 15/40 oil, as well as lugging the engine (manual shift), made my engine crank look similar to the condition of this one. With age, one tends to get wiser on how to make an engine last longer. Hopefully, my well maintained 2016 6.7 liter makes it to 300,000 without major complications. Just don't know how tuff this engine is, but it pulls a trailer uphill at an acceptable speed with plenty of throttle left.....

[@jibrilthegreat35]

I have 200K in my 12 6.7L psd. Runs great, burns no oil. I dont see why it wouldnt make it to 300K easily. I use it on a service truck that weighs 20,000 lbs so its always under a load.

Nice teardown. My early 99 7.3 has 450,000 miles and going strong. Maintenance is the key. Fluid and filters. I replace the 4R100 trans at 423,000 and last year 2 injectors needed to be replaced at 435,000 miles. Other than that, no other engine work has been done. Long live the 7.3! Thanks for sharing.

I have a 97 F350 with this engine and it was pretty cool to see how it comes apart. My parents bought the truck new and it was passed down to me. I hope I can get 700K miles from it, although I doubt I would drive it that much. Currently it has just over 100K miles and still running strong. I have only had to replace the vacuum pump and rebuild the AC compressor. It have been a very reliable truck.

I hope you have a good Monday morning and enjoy your day today and I enjoyed your 700k tear down but if you are going to sell builder's packs keep the parts in order where they came from and you can get it done. It's easier, cheaper, and more easily rebuilt if you can get what you need and use some old stuff. Hense keeping it in order, can't reassemble a motor putting parts all over the place. Great job and great day to you Eric!

I'm going with 700,000 but it has had some work done (as shown by 2 reman injectors). depending on the specs of the cylinders might be rebuildable. Note the cross hatching is below the wear ridge of the cylinders thus indicating they were done more recently (after) the wear on the cylinders and so were lower in the bore than normally done in a build.
