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!!!!

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.

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.

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.

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 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.

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.

Only problem I had with the truck was the auto locks front differential and recall on airbox for the filter. Did have injector change and routine maintenance and a crap load of tires.. I bought a new Dodge ram 3500 and as soon as warranty ran out I needed to have transmission rebuilt, made it bullet proof and ended up being a great truck minus the fast acting rust that the Ford never had. Both was used in hauling marine equipment and boats. 7.3 was a beast!

Love my 7.3 F250 Bought a 70s model F600 with 4 speed split rear and a 16ft dump bed. 53k original miles, was an old grainer spent alot of time in the barn or doing occasional odd jobs, great interior and body. Doors close with the press of a finger, really nice truck. I've heard that pulling these gas torqers like the 330 that's in it and dropping 7.3 set up in them makes a good difference on older 600 series trucks. F250 sometimes cant bite because not enough weight for the torque especially in low 4x Would be interesting having another 12k pounds of traction on that 7.3 with the split rear 4 speed. I bet it could crawl about anywhere it could get a good bite.

And bad oil is what causes failures in the HPOP System on those engines the majority of the time.

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 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.

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.

The removal of the manifold bolts was awesome. If that was an LS you would have broke 17 out of 16 bolts.

I drove one with 1.5 million miles on it. It was still running strong when was pulled. They are resilient engines.

My 2000 has 396,000 miles and it’s still running very well.

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. Oh, and it still gets 19 mpg on the highway. I have no complaints.

Although I retired as a school superintendent and a university teacher, I did my own maintenance on our private vehicles and helped my brother doing maintenance on his airplanes which he used in his fumigating business...When I joined the U.S. Airforce, I went through formal training in aircraft maintenance...I trained myself to work on BT-13s, N3s, and other lighter aircraft...I trained on the B-25 and B-26...I then trained on the B-36, B-47, B-52, and other aircraft...I worked on the Canberra and the XC-99 as well...To make a long story short, I still tinker with anything mechanical, but most of all, I watch videos of other folks, such as you, take different engines apart...I thoroughly enjoy that and will continue to watch your videos and those of others until who knows when...By the way, my brother, a WWII veteran was a licensed instructor pilot, in different kinds of aircraft including helicopters, and he took time to teach me to fly...

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

I don’t care how long your videos are, I have loved every one. I’m going with almost 700k. Keep up the great work. On a side note hope mom and baby are doing well. And congratulations on having another kid.

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

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

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.

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.

Loved this longer tear down, thank you posting this!

It’s great waking up Sunday morning, and having a coffee while watching a tear down and waiting for the world to wake up. There’s a project waiting for me in the driveway afterwards.

Another good one to watch is Rainman Rays Repairs. Another one that’s honest as the day is long.

Longer videos are always welcome as long as the content and details are justified by any extra time keep it up highly enjoy watching

Your channel is great! It reminds me of my job at an US Army Aviation Intermediate Maintenance unit in Germany in the early 80s. We had a saying “ if we can’t fix it, we’ll fix it where nobody can”

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

These engine teardowns are great btw. I love watching your videos :)

My BIL has an 01 Excursion with factory 7.3 on a 1 ton chassis. Bought it brand new (had 4 miles on it) and it now has 610k on it. We tore it down because 610k plus the Trans and T case needed work also. What you are seeing is high mileage and idle time. My BIL had never been opened up since new and it looked really similar just not as bad on the cams or rod bearings.

That's a million mile motor. 7.3 PowerStroke is a beast of a motor. One of the best.

why are these teardown videos so relaxing for a sunday afternoon?

Would love to see a 6.7 Powerstroke

Definitely a workhorse of an engine!

As a owner of several high mileage 7.3s valve cover gaskets always will go out and out of 5 all but one has had to have the number 7 and 5 injectors replaced. Cam Positioning sensors on all of them. We do oil testing on all of them and have for the intire time weve owned them. 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. Starting this year we will be replacing all of these trucks with 2024 6.7s. My dad had a 2000 7.3 with 863k before it finally grenaded and threw a rod out the oil pan lol. Best engines we have ever had.

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.

When working on diesels lifting equipment is you friend! I remember trying to get a 671 Detroit head down a ladder into a boats engine room. Even with 2 of us I thought for sure I was going to blow out my back. I think the 671/12v71 head is well over 200 lbs it really sucks to deal with.

Intertubes say 238# with valves, 320# with rockers, bridges and followers. Makes my back hurt just thinking about it.

For those rusty exhaust bolts, I have had huge success with the Irwin extractor sockets, they bite hard on even fully rounded heads

I like the longer video's you go into more in depth with the explanation on all the parts. As always another amazing job and video.

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.

Geez that’s quite the talent you have. Never seen anyone that can heat steel with his breath. Keep up the good work I love your video’s. Very relaxing for me.

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.

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 know a guy who drives a ‘99 f-350 with the 7.3 in it for work and it has put well over 700,000 miles on it. The engine is pretty much original besides injectors (i think he’s on his third set) and maybe a new turbo. He definitely babies it, hauls no trailers besides his camper once a year, practices maintenance as a second religion, and always runs power service in his fuel. I would have to say that the entire truck will rust away before that engine dies

"Let's get my little pry bar" (casually picks up pry bar that's taller than he is)

Those cylinders look amazing for 699K miles. There’s a reason guys love the 7.3 , just like the older 2 valve triton gas motors they were simply better than the newer stuff. Ford kinda went backwards for a minute..

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.....

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.

That was a really fun watch, love those 7.3 engines, nicely done.

Cracked 7 and 8 pistons are normal due to extra heat cycles by the firewall/turbo. All v8 ford diesels have these, less so on the 7.3 but still a thing

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

I'm still running a 7.3 IDI in my 1991 f250 4X4 with 830,000 miles on it. Engine has never been apart.

love that you add humor into your vids awesome work brother keep it up never a dull video !!

My 7.3 has 264,000 so far, and other than many accessories like water pump and ac unit and alternator, and some oil leaks it’s doing well. Darn good engines.

Love 7.3s, you handled the heads perfectly , those loops up top are for moving them , I’ve always done them with a engine hoist , anyway good content

looking at that engine inside and out is exactly why i run lots of additives and keep the outside of my engines super clean as well. i want my engines to look like new the day they finally wear out.

Very entertaining to watch. Your camera work is really good and clear.

With that cam that wiped out...700K for sure...as for the truck itself...it had a hard life for sure. A great video Eric:-)

The 5.3l in my 02 avalanche just hit 700k. Motor has never been re-built. Its burning a little oil, and is very tired, and the piston slap its done since new has gotten to diesel sounding levels, but its still ticking.

Very nice! Looks like a well used engine, though amazing how good the crosshatching can look with proper maintenance. I know you don't typically get VW/Audi engines in but would love to see a teardown of the 1.4 TSI or a 24V VR6. As well as a FCA 2.4L Tigershark or 1.4 Abarth engine

makes you wonder how may revolutions that motor made in it's life... impressive.

I know next to nothing about engines, yet found this video surprisingly cathartic.

I always watch and share the video you make and right off the bat that is the magic you have been working on because I am a mechanic and I have owned, worked on, and I know that just so far in you are making this look way too simple, but I am going to say that you are getting to the point of editing genius. Great day to 5on this Sunday morning.

I totally agree with your assessment. There was a video of a fella tearing down a 900k 7.3 and it was in similar condition. They are just really tough low hp engines.
