The sound of a consumable part getting thrown across the shop after a "it's in pretty good shape" quote never gets old

The injection pump was loose because he tried removing it before selling the core to you. Those three bolts are actually studs - the pump is held on by nuts on those studs which doesn't require access to the geartrain side of the pump. What the PO didn't account for was having to take the drive nut off the front of the pump and likely gave up, leaving the pump loose like that.

As a former Master Nissan tech, seeing broken crankshafts were extremely common on these 5.0's, especially the 2016 MY. The crank had a weak design, and they would break in the area in the video. If they were kept stock and not juiced up, they generally were ok. Lots of farmers in my area bought the Titan Diesels and expected Chev/Dodge/Ford diesel power out of these engines, but they weren't intended for that kind of work.

I broke a crank in a 87 supra between cylinder 1 and 2. Felt a slight vibration and pulled over in the middle of nowhere 20 miles from home. grabbed the dampener and could feel the crank wiggle. Figured screw it and drove it home. Amazing engine Toyota made, ran on all 6 with a slight vibration. Rebuilt it and drove it for years.

Hey Eric. I'm a parts guy at a Nissan dealership but I've never even seen one of these come in, so this video was quite a treat. We actually wont even work on these trucks as our lifts REALLY struggle with them. They can weigh over 7,000 pounds. They've actually broken a couple of our older lifts from what our master techs have told me. Gas titan engine cores are QUITE common. That'd be an interesting teardown. Love the channel man, keep doing what you're doing

40:06 It's probably torsional vibration. You see this with the Ford 300 I6. That thing is FUCKING INDESTRUCTIBLE, and the stock crank is more than happy to spit out over a thousand horsepower if enough snails are hung off the side. But if you rev it much past 6500 that 3 foot long crank just vibrates itself clean in two. Starts resonating like a guitar string and POING!. Straight six Cummins diesels in Ram trucks are known to do this when revved much past the factory redline as well. Fix is the same in both applications: Fit a harmonic balancer that is capable of changing the resonance so the crank doesn't explode itself. It's also why those straight eights you see in cars from the 1930s, 40s, early 50s rarely revved much past 3,000RPM. The cranks were so long that they would start resonating, snap themselves in half. V8s tend to be much more resistant to this failure mode because their cranks are much shorter(And thus resonate at much higher frequencies), but given this engine was 'tuned' it's entirely possible that it simply revved high enough to vibrate the crank apart. Where this crank failed also lends credence to this. A crank that fails due to excessive torque on it is usually going to shear the snout or the flexplate flange off, depending on which end was connected to the overload. A crank that fails due to harmonic resonance tends to fail right there where it necks down into a journal somewhere. My best guess for this engine's cause of death is operator error. Excessive RPM due to the operator deleting/raising the rev limiter and pushing the engine too hard without making the appropriate modifications to support that higher redline.

I recently went to a Cummins Insite/Aftertreatment class, and someone had said that the 5.0 is the least desirable engine Cummins has ever made.

Former Titan XD diesel owner here. I bought my 2018 Titan XD midnight edition new in September of 2018. Had 190 miles on it at delivery. It was an absolute amazing truck and handled every load I put behind it amazingly. In January of 2022 it started to sound different, like a knock rather than a clatter that a diesel typically has. This was at 47,000 miles. I took it to Nissan numerous times and told them something wasn’t right. They had corporate specialists come in and look at the truck and I was told numerous times it was fine. In May of 2022, with my fully loaded 8.5x20 enclosed trailer attached, the crank snapped at 55,000 miles. It was violent. Nissan replaced the engine at no cost to me. Total bill was over $22k! I sold the truck to Carmax 7 days after getting it back. Really miss the truck, but to much of a risk when using it at a commercial vehicle.

The guys in the Titan XD group will love this.

"Spins nice. No damage to the impeller." "WHAmmmmmm!!"

I LOVE the recent diesel content. A lot of people are undereducated in the operations of a diesel engine and just tearing it down provides a HUGE understanding

As a Cummins owner I loved this video. The crank failure issues is unfortunate. I was aware of this engine dating back to the early 2000s as a DEER development project. There was a V6 as well but it was never developed to market. I am hoping you’ll do a teardown of a 3L baby Duramax.

I truly love watching your engine autopsies. This one was remarkable. I am by no means a mechanic but these videos are really an education in themselves.

"It generally helps to get all the bolts out. That's been my experience" 🤣

Since you asked, according to the Service manual, torque spec on the interior head bolts is 89ft/lbs (120n/m) plus 180 degrees. The outside ones are only 17ft/lbs (23n/m).

I noticed that high pressure pump didn't have threaded mount holes. Those bolts you removed from the front were likely just the mounting studs for it. It probably had nuts on them from the back side of the pump. Someone probably tried to remove the pump and keep it when they realized it wasn't so simple to remove and they just left it in the halfway pried out position you found it in.

That engine was originally slated to go in the 1500 RAM. But it wasn't efficient enough, so Chrysler went with the ecodiesel. Another fun fact, before Nissan picked up the 5.0 Cummins, Nissan was considering the Navistar 6.4... Dodged the bullet on that one Nissan!!

sweet, never seen the insides of this engine. my 12valve superiority complex kicked in. excited for this teardown

So good to have you back, great tear-down as usual.

Thanks for sharing. As a former auto technician, it is fun to watch. It is much easier to take an engine apart when you know you are not going to have to put it back together.

What an engine to find for a tear down! 👏 I'm guessing that CP4 was pulled back because the owner or shop wanted to keep it/reuse it, as they are not cheap. But since it required the removal of the front cover, I'm guessing they gave up. Looks like that chain guide was damaged in the process of half-removal.

Now that was a wonderful bit of carnage. I was shocked at the blue ting to the crank. When you popped off the oil pan and I saw the crank weight I thought it was almost like firearm bluing. I really nice shade of blue there. I agree with you, that was a very noisy shut down.

Wow, this was a good one. I can only imagine the heat this failure must have generated. That blue coloring was scary… bet that crank was glowing red-hot.

This is easily hands down my favorite YT channel. I came for the VR30DDTT teardown since I have one, and I stayed for the shenanigans. This dude is like my spirit animal LOL.

The nice comments about the water pump gets me anxious for the MLB pitch to the scrap bin that's about to happen😂

Man I was starting to have teardown withdrawal lol glad you're feeling better!

Glad you and the family are feeling better Eric!! Your fans certainly missed you last Saturday. I drove a 2017 Titan XD diesel 4x4 crew cab for just over three years for work. At 79,000 miles it went into limp mode one morning on the way to work. After nursing it a couple of miles to the Nissan dealership and dropping it off, we found out 3 days later that the actuator that drives the hybrid-compound turbo variable geometry had failed. It took four weeks to get one because they were failing at an alarming rate. I naturally did some digging on KZfaq and came across a video where the same thing happened to another guy - but his failed at about 40k, I believe. When he pulled all the piping, the turbos, and the actuator off the engine, he found that it was so badly coked up, that they had to scrub it with gasoline to get it clean. Come to find out, this had been happening all over America with this engine and Nissan was trying to ignore it. I sent the link to the video to my service guy at Nissan and asked him to please pull all of the turbo piping and the turbos to inspect and clean them. He said “No” because Nissan wouldn’t pay for that under warranty, only to R&R the bad actuator. I asked him if he had watched the video, and he said he did. I asked him if he had kicked it upstairs and he said he did. I asked him what the response was and he said they wouldn’t comment on it and to replace the bad part. Four weeks after the truck went to the dealership, we got it back. 8 weeks after we got the truck back, we sold it before the warranty was out. The same thing happened to the other Nissan XD diesel in the company fleet. Same scenario: about 4-5 weeks to get the part, and we sold the truck about a month after we got it back. It’s too bad. That could have been a great truck. Unfortunately, Nissan had to monkey with the engine instead of just buying it from Cummins. It was overpriced, barely had more towing capacity than the 5.6 gas engine, and the transmission totally sucked. The truck was quiet, rode nice, and got pretty good mpg’s for what it was.

Glad you're feeling better Eric! A broken crank...now that's impressive...

Good to see you feeling better dude! Always look forward to the videos! I have had my fair share of broken cranks and you would be very surprised at how little to almost no noise they can make depending on where the break occurs. I pulled a 454 out of a customers truck because of a low oil pressure and very faint odd sound complaint, truck had 135k on it at the time and the customer had told me it had the faint odd sound for almost a year prior before he brought it in. he didn't drive the truck daily, it was only used when towing his 36' RV. I personally drove that truck during the diag process and if you were not listening for it you would never know that is how quite it was. I couldn't believe it when I tore it down the crank came out in 2 pieces just like yours just did however it was a clean break right in the center journal. it was like 4 of the cylinders were running separate of the other 4 but it was such a clean break that the 2 pieces were still in contact rotating together. I still have that crank on the shelf and I often get asked the story on it I would have never believed it myself but I had to I was looking at it with my own eyes! Keep up the good work Eric and thank you for sharing!

These things sound cool as hell too when certain parts fall off, mix of a newer Powerstroke and a Duramax.

I had one for 4 years, and LOVED IT.

I have a 2016 Titan XD Cummins with 62,000 miles and it runs fantastic, I bought it used with 23,000 miles and it had AFE performance products on it. When I did research on this company, these are modest modifications, Momentum HD Cold Air Intake System and scorcher power module as well as the 5" exhaust. I think this really helped the performance of my truck without overkill. I also got a letter yesterday from Nissan, they are giving extended warranties on the Turbo Actuator and the Turbocharger for 10 years or 150,000 miles from the manufactured build date. Plus if you had them replace you might be eligible for full reimbursement, if you own a Titan you should have the letter or get it soon. I love the truck and have no desire to abuse it, love the tear down watch it all the way through, great video!!

That's a new one for sure... Great job as always, glad you are feeling better... It's nice to get to watch these again,Thank you as always...

Interesting tear down. Good to see you have regained your health. Thanks for the video. 👍

Thanks for giving insight on the general value for a stripped core.

You are a good mechanic and a great teacher.

Got to love the home cylinder deactivation method!

Well, I had a 1980 Camaro that broke a crank. It was a 327 that I built which included a high HP at lower RPMs cam. Heavy car with a 2.56 rear end but still. The crank broke right at the rearmost main. Turns out it was welded up there and sold as new from NAPA. NAPA made good on the crank by replacing it. When it broke the engine sounded like it was full of unbreakable coffee cups.

Really enjoy your content bro, keep it up and don't change.... love the consistency as far as what I learn and how you entertain with the "thats what she said" and bad dad jokes..... always a great addition to my week. Take care!

I own one of these and seeing the insides is a treat. The 5.0 is almost indestructible if taken care of and and not abused, mine has 100k on it and runs smoother than new. Oil analysis shows no wear concerns yet. The tranny attached make the combo surprisingly beefy, overbuilt. I understand folks who question the 5/8s size and 6 lug hubs… I feel Nissan missed a LOT of sales not getting closer to what the other 3/4 tons can do. I pull mostly a single car hauler and the 5.0 is never overtaxed.

Boy does it feel good to watch another teardown!

Straight cut gears on the camshaft drive! Must sound sweet...your most polished video yet, welcome back!

Glad to see another 'new' engine on this channel, but I'll watch any teardown here happily.

Glad to see you back on your feet

I was going to start shaking like an engine running with "one bad cylinder" but this teardown showed up just in time.

Nice friend of a friend you have there! Hopefully he gives you some money back for that rusty lump.

Good to see you back in action. don't overdo it like that tune!

Eric, a great teardown as usual. You have people at your shop, I suggest you remove the casters from an engine stand and weld it to a nice heavy piece of steel. Weld a few loops for forklift tines to move around the shop. It would make teardowns so much easier not to have to chase the engine stand all over the place!

Expensive failure? A that's a pretty good description of that entire engine program. A complete commercial failure. As well as being a mechanical failure.

another wonderful video, I was an electrician for the C&NW RR, we had a couple EMD SD45 crankshafts break, 20 cyl 645 cu/cyl 3600 HP crank was probably 25 feet long, head crab nuts torque 2400 lb, main bolts 750 , rods 450

Wowsers, what a ride. Thanks for another great video, Eric!

Actually catching that bearing hit the floor and skitter so melodically across it...Beautiful my friend. Absolute gold. Great video, Great series, Great guy. I wish you all the best in the world.

I always appreciate your way of teaching people appropriate way of dealing with used water pumps, i.e. tossing it something hard and try to make as much noise as possible.

Good to see ya back on a teardown Eric, missed ya last weekend! That said I hope your feeling better man!

Please update us on what you do with the Engine and after a thorough cleanup on how everything looks and what's usable. I would love to see the condition of the bores and pistons . I would love to see a rebuild on your channel if you end up scoring a deal on a crank. Keep up the 5.0 Cummins videos I love it!👌

THANK YOU ! Just a non mechanic guy but love to watch these vedios on KZfaq. It helps me realize that I need to just continue watching and not quitting my office job. Hat's off to your talent. AWESOME editing !!!

Some diesel engines do have pistons that come out of the deck about as much as the thickness of the head gasket, makes for more or less zero piston to head clearance for maximum compression. But also no room for mistakes, pretty easy to smash some valves that way.

That pretty blue crank remnant will make a nice desk ornament 😄 That engine looked very clean inside for a diesel with over 100K on it. Tuning it likely disabled EGR, which makes for a clean minimal soot diesel. It also appears probable that his tune disabled the engine itself by snapping it's crank in half.

isn't this the truck that Car and Driver Magazine did a long-term test on and called it something like 'the worst vehicle we ever tested' due to all the mechanical and electrical failures?

I test drove one of these and a 5.6 gasser on the same day with my 18 ft boat, and there was absolutely no reason to deal with emissions, starting in -30, and high fuel prices. That 5.6 is a beast of a gasser.

The V-8 Vivisector is back in action! Beastly teardown.

I knew what you were in for the minute the HPFP pissed out water and fuel on the bench. FWIW broken cranks can be surprisingly quiet on gassers, I snapped one on a Ford with a stick, drove it for months, thought it was the clutch because I could feel it in the pedal. Changed the clutch, no difference, didn’t figure it out for another month when I was in a hurry one day and wound it up and it snapped in a second place on the other side of the rod journal, freeing the rod and allowing the crank snout to flop around and the timing belt jumped and it stopped running. Did a 6.2/6.5 GM diesel once, snapped diagonally inside the rear main cap, sounded like loose torque converter bolts.

Very interesting - this is the first I have seen one of these engines torn down. Great video

Probably didn't get much from it except an awesome teardown. Thanks, great video

Actually i worked on a duramax 6.6 LMM with a broken crank and it was running and sounded more like an exhaust leak coupled with a cylinder misfire... I was in shock when i determined it was a fractured crankshaft.

Fun fact: The XD Nissan Titan is a 5/8 ton truck.

I can understand the crank breaking if the vehicle had a manual trans and got treated a bit roughly, but not if it came out of an automatic. Another interesting video!

Excellent teardown!! Thanks Eric

Happy to see you back and healthy. Great video as usual. I bought a 55 Chevy with a 283, PO said it would run if I reconnected the electrical. Turned out to have a broken crankshaft as well. It was definitely noisy 😃

I'm pretty sure warm salt water is rivaled only by sulfuric acid when it comes to corrosion on steel parts 🤣🤣

Like the change from hammer handle piston plunger to brass soft.👍👌

Really enjoyed the Nissan! Thanks for taking the gamble of maybe a good block! Way back...in the middle ages I had an International UD-14 diesel, running a saw mill. Started on gas, switched over to diesel. I have no idea how many hours it had on it. One cold morning I started it, no either, and it started hammering. Quick inspection through the plate on the bell housing, and the wobbling clutch assemble gave the terminal diagnosis. Nope, didn't fix it, sold the whole lump of iron to someone else, and bought a UD-16 to replace it. Really enjoy your running commentary, like using your brother-in-laws favorite shirt for an oil rag! Appreciate your youthful humor and instruction.

Now Eric we know the strongest part of any engine are the wrist pins 😅

15:19 The torque spec is about tree fiddy.... Plus 90°

Hello Papi, it's good to see you doing well. You have a great support system at home and a very incredibly strong immune system to be back at it so fast. I am like you, I think better and feel better when I am in the work zone. However, my Covid encounter wasn't so good, lucky to be alive I am. Your videos rock brother, I dig them a lot. See ya in the next post my man.

I sure like watching you tear down. It is such a mystery and I am always wrong.

I had a 17 5.6 gas Titan, they had tons of engine replacements. Mine was knocking with 28k. The motor is powerful but…transmission wasn’t nothing to brag about, shifting points were horrible.

I have only seen a handful of these on the roads in my area. Great teardown. What’s the eta on a 1.4T Fiat multiair?

Failed engine teardowns are always interesting. Some catastrophic failures are way more interesting than others.

You would be surprised how quiet a broken crank can be! I have driven a diesel engine for over 500 miles home in a 36,000lb truck, used it a month, only to discover the crank was always broken! Seen it building diesels for AG tractors also they fail in a way that they keep turning. Only indicator initially was a constant blip in the oil pressure gauge. Bad harmonic balancer once, someone mismatched bob weights by 2lb other time! Still went 200+hrs in the field broken!

To me it looks like a fatigue crack that started at the journal radius. If you still have the crank you might look closely at the other side of the broken journal and other journals. It's normal for multiple fatigue cracks to start then one grows to failure.

That guy not only used an Amsoil filter, I'm willing to bet that he used their oil as well. That engine was spotless under the covers. I opened up a 2.0 4G63T with 215k on it, that I got from an Amsoil dealer, and you could have used the valve cover as a dish.

Sweet. A Cummins V8. Always thought these were unique motors. Awesome video 🐸

I got a new Jeep Sahara Unlimited from Punta Gorda, FL for parts, but trying to get the motor to turn over just out of curiosity. Drained 2 gallons of salt water from the oil pan.

I always love these guys who think they can out tune the Cummins engineers

Had to run out to my truck at almost midnight to see why the CP was pulled back like that. It’s pretty obstructed, but it looks like those bolts must have been cross threaded. Been waiting for this video forever!

The sped up " that's what she said" at 30:03 cracked me up. Really like the humor in your videos

I broke the crank on the Cummins engine in my Peterbilt 389 this year and the noise is painfully obvious. Love the channel.

That engine looks quite delicate to be a diesel!

That looks really damn clean for a diesel!

That was very interesting and you did a fantastic job of explaining the failure.

Thanks for bringing back the water pump accent. Love it.

I bet it was a spicy tune that snapped the crank in 2

It was RUNNING! That’s crazy, it was running as two separate engines: a V-twin for the accessory drive and a Chrysler 239 V6 to spin the wheels. I’m sure it was rubbing and bumping but I could see where it would tend to stay together.

A few episodes ago I asked for a broken crankshaft and I got it. Thank you

Amazing camera work thank you

The WABCO label on the vacuum pump is kind of interesting ... they're more well known for making parts for railroad locomotives ... I know the Titan is a pretty big truck, but ... no, it's not that big.

Based on the journal offset, I'd say it doesn't surprise me that the crank broke, especially with power mods.

Head torque specs: tighten to one Eric-meter. (screw Newton, he didn't know anything about cars.) Glad to see you're back!

Hi, wesley here, current bright yellow titan pro4X cummins Titan owner, former Nissan master certified diesel, ev, hybrid, gtr tech. The front item is a vacuum pump, and the vacuum pump has to be removed first to remove the fuel pump. The fuel pump uses a special tool for gear removal/installation so there was no taking off the pump which led to guide damage. Hope mine lasts to 100k lol
