5.0L Cummins Engine Disaster, only 40,000 miles, out of Nissan Titan

I think that's pretty standard practice in the industry. You gotta commit to paying for the diagnosis but if you agree to the teardown and repair then they waive the diagnostic fee. It doesn't make good business sense to charge $5,000-$10,000 or more for an engine rebuild and then still hit them with the diagnostic fee too.

I met a regional sales guy for Cummins, and his company truck was a Titan XD with the Cummins 5 liter. I asked him what he thought of it, and the immediate look on his face told me everything I needed to know. His eyes held this fascinating mixture of disgust, bemusement, and more than a little shame. His gaze shifted downward. "It's a company truck." he said as a slow smile crept over his face.

[@apolloomd4939]

I have a standard V8 Titan bought new and love the performance but that being said… throttle body went out at 20k resulting in having to have my new truck towed. The towing was covered by Nissan and everything was taken care of with the warranty. 39k had to have engine mounts replaced which was under warranty. The dealership had mounts in stock because it’s a known issue. I baby the truck with no off-roading. Glad I bought it from a volume dealer with a lifetime power train warranty. Love the truck but will see what else comes up. Puting it out there for other owners to be aware.

[@warntheidiotmasses7114]

Nissan has a management team Hell bent on destroying the company. There's no other explanation. They car transmissions are crap, the cheap on everything. So the conversation with Cummins probably went something like this, build a 5.0 at half the price point you offered. I suspect a conspiracy is afoot in order to send all car manufacturing to Kissinger's Chinese factories.

Then go hit the dirt roads around the farm.Once you get sideways push in the clutch throw it in 4high and give it hell. The long arm suspension was being fully used. It was fun. This is my only nissan ever. I stacked the main bearings in my yota doing the say thing as my beater. I do maintain and change the oil regularly. I assumed they were all like my boosted beater.

[@jasonlitton9136]

I used to work for Cummins in engineering and testing . This engine was designed back in 2006 for the Ram 1500, then economy crash etc. It was shelved for many years and eventually Nissan came in as a buyer, Toyota was looking but ended up not doing anything. I had several of these engines in test bays and had them in extreme conditions. Some made it some did not. There was an issue with the crank bearings for the earlier year models of the Nissans, lots of engines were replaced under warranty. The issue was eventually corrected but the damage was done. Also being an older design power ratings were pretty low for modern diesel standards. Basically it is putting out as much power as ithe design is capable of and efficiency isn't that great. It is no longer made and existing stocks are likely dwindling with all of the blocks that were failed. It was a good idea at the time but economics preventing from coming to market when it was originally designed and was never updated, also the bearing issue wasn't really discovered until it went into vehicles. So it is Cummins engine that really didn't live up to the name,, unfortunate but that is why it wasn't around long on the market

Big credit for the way you talk to the customer explaining everything in detail. As an engineer myself I hate workshops (especially oem dealers) not explaining to the customer- often because they don’t understand what they are doing. Often billing for unnecessary stuff. In case of these engine disassemblies with many work hours, you have to explain to the customer so that they see that their property is in good hands.

[@digger105337]

Has anyone done a ( Natural resources and pollution) study to see if the small reduction of crankcase emissions is worth all the cost of engine life expectancy? Need for a replacement vehicle or engine has to have a negative effect vs the engine/ vehicle lasting longer and not needing replacement. I bought a 2000 yr Motorhome with Cummins diesel that has no real emissions device, no def, no dpf ,no EGR 130,000 miles on it and zero issues, no fault light , absolutely nothing but regular service. I picked the older unit because I'm a Cummins certified mechanic and I knew these petty emissions rules would kill the life expectancy of the Engine, the largest most costly part of the Motorhome. Having a dependable 450 hp engine gives me piece of mind climbing Donnar Pass and other long large hills in the West. If I or anyone needs rebuild service, your top of the list. Like your professionalism and honesty.

[@nerd1000ify]

The crankcase fumes are the lowest hanging fruit for emissions. If you look at real old photos of highways from the '50s you'll note the black slick down the middle of each lane, that's oil from the road draft tubes on everybody's engines. Obviously most of it just dripped on the ground (bad for the groundwater, but not getting in your lungs) but there was always going to be some mist too. Fitting everything with a crankcase ventilation system cleaned the air up a lot, and only costs a few bucks per engine. So much so, that even el-cheapo mowers have a crankcase ventilation system. The real source of all this grief with clogged up manifolds is the EGR, or more specifically the manufacturers' choices on how to build the EGR system. The usual practice to operate an EGR system on a diesel is to set the engine up so that the turbo creates more backpressure than the engine runs boost. The excessive exhaust pressure thus forces exhaust gas from the exhaust manifold through the cooler and into the intake manifold. There are obvious issues with this approach, not only are we sending sooty exhaust into the intake but we are also subjecting the engine to more heat and stress from a restrictive exhaust. Now that everything has a DPF, there is also the option of collecting exhaust downstream of it at which point it is soot-free and won't clog the intake. Which sounds great, but there's no backpressure to force the EGR in. This problem can easily be addressed by putting a throttle valve upstream of the turbo and using it to constantly pull a mild vacuum in the intake, then the EGR gas will be sucked in along with the air, compressed by the turbo and fed to the manifold. No soot, no problems. So why don't they do it? I suspect they want to save a few bucks on the throttle valve and extra plumbing required by that system, and don't give a rat's about the effect on longevity because the engines already outlast the warranty period most of the time. Alternatively, you can take Scandia's approach and ditch EGR entirely. They've basically decided that it's better to accept using DEF faster and not run any EGR at all. And I'm inclined to agree. Without EGR the engine will be more efficient, have less DPF issues (the NOx produced by EGR-free combustion actually burns the soot out of the DPF!) and last longer. Which probably adds up to a net saving even though you have to fill up the DEF tank more often.

[@joshwinkelstein407]

You may call them "petty", but I remember when I was in junior high in the late '60s in Oakland CA and when the conditions were right, the air would make your eyes water and you didn't take any real deep breaths. You could not see the hills from the front of the Grand Lake Theater. While that is not a scientific study, it is no longer like that when I return to Oakland, any time of the year. Personally, if I have to trade engine life expectancy for MY life expectancy, I chose me.

[@1eastked]

The 5.0 has been a complete debacle. I was so excited for this motor to.

[@wademills1616]

I was excited for a diesel in a 1/2 ton. But was disappointed it wasn’t a large 4 cylinder or a small inline 6 cylinder. It’s sad that if your over a certain HP your emissions exempt. But not when it’s a small engine. If they would have put the 3.9 or the updated 4.5 in them and turned up the pump. And no emissions you would have had something.

But for some reason the oil in my own 12 valve Cummins will still be carmel colored after several thousand miles. And even at the oil change interval of 150-200 hours it's still not completely black.

Dave's initial assessment, that there was blowby, which caused the oil leak(s), then the engine was ran low/out of oil, is likely the scenario. As to what caused the blowby, that could have been a malfunctioning injector dumping fuel, causing a burned piston, broken compresssion rings, or other situation that started leaking compression into the crank case. I am an engine core buyer, to that end, I part out a lot of Cummins (Ram), Power Stroke and Duramax engines and it's almost an adventure with each engine, as the damage can be widely varied. Each revision of a given engine platform can have it's own unique issues, almost on a year-by-year basis.

Cummins makes heavy automotive engines, engines for heavy trucks, farm equipment, mining and geoengineering equipment, scrap yard and recycling equipment and even fixed and portable generators. The V8 Cummins Diesel is repurposed from industrial engines with an automotive emissions system grafted to it.

Lots of wiring harnesses go in these. Check the injector harness for loose pin pit. 8:48 The injectors don’t receive a good connection causing overheating. Thus, lots of separated crankshafts. Also lots of turbos, egr’s, transmissions, heater box’s…the list goes on.

Lol Cummins stopped making v8s a long time ago for a reason They basically said ok even though that V8 diesels suck go ahead and knock yourself out by putting them in a Nissan. Also you can thank iveco or whoever decided to reinvent the wheel on the 6.7s because it wasn't all Cummins. When Fiat bought Dodge they were bound determined that they were going to try and eliminate Cummins from all of their acquisitions. First they started on case IH but they realized that they couldn't do on dodge so they came out with the 6.7 with a mixture of iveco and Cummins parts.

Also a lot of oil manufacturers have removed sulfur from their oils, a critical ingredient for diesels.

I worked as a Diesel Fitter @ coal mines in Australia. In 2011 we received the first C series V 20 Caterpillar 797 F ultra class trucks. Caterpillar put soft main bearings in the engines. Arrived @ work 1 morning, there was a 20 hour old engine sitting on the work shop floor in a cradle. There was a hole in the side of the block, about size of a mans head. Con rod made a bolt 4 freedom. Caterpillar had 2 remove engines from the whole fleet.

[@tylersmith7054]

I was extremely close to buying one of these. The idea of a small diesel “heavy half ton” or “5/8 ton” pickup was a just right option for me. I did my due diligence and researched them thoroughly and learned they have main bearing lubrication issues. They kill the bearing and snap the crank. There are several very thorough posts online. In the end I went with a Ram. I don’t regret it but I still love the idea of what this truck should have been.

This is obviously a case of very little maintenance. Modern diesels need a 5k mile oil change. Nissan wont cover this under warranty, they will say this was lack of maintenance. Manufacturers will do this to get out of these huge repair jobs.

[@jakobkits-goldstein5878]

Well Dave I watched your video when it came out because I own a titan and I've been seeing more and more of us with this same issue. I figured I was good with mine it's been a great truck, always on top of Maintenance but last Monday my truck shut off while going highway speeds, lost everything was scary as heck. No warning, no bang, no engine lights. I checked the fluids that morning, I'm a heavy duty tech by trade and have only owned diesels. 167,000km and I now own beautiful lawn ornament. Still owe alot on it, and parts are insane to fined and pricy as he'll. Can't wait to see what you do. Im unsure as he'll on what to do. If I put a used motor from anything but a 19 (revised crank, cummins knows there's a issue) my truck is a ticking grenade again and id be so deep into it with a new engine I couldn't get rid of it. First "new" low milage truck ive owned in my young life. Didn't expect nissan and cummins to leave us guys behind. 28k canadian for a long block. 15k for a used motor from a wrecker, 20k for a used 19 motor. 14k at nissan for a short block and crank.

That’s a Fleetguard oil filter they pulled off which is first fit for all Cummins engines. I got $100 bucks says the dude never changed the oil in 40k miles.

[@fewworddotrick]

Absolutely nothing to suggest that happened...most guys use fleetguard- no reason not to as it's oem and it's just as affordable as aftermarket. There's gotta be hundreds of cases of this happening on trucks that are maintained perfectly fine. At the end of the day Cummins dropped the ball plain and simple- and the worst part is they shrug their shoulders and leave the customer out to dry. Tons of these engines blow up right around 100k-105k which is the mileage that the warranty is over. Cummins and Nissan blames a lot of them on deleting but I think most of the damage is done while stock and then the extra hp of deleting is the last straw.

[@fewworddotrick]

I've heard of several people having this issue with those trucks and both Nissan and Cummins always shrug their shoulders and leave the owner paying the bill. To me this is a Cummins problem. Nissan did not make the engine they merely bought and installed them. I used to respect Cummins as a brand but this debacle has tarnished their reputation not because it happened but because of their response- which has been nothing. Gotta be hundreds of thousands of these things driving around and they act like the engine is not their product.

With it wiping out all the bearings, it was starved of oil. If it got ran low or the oil pump went bad only time will tell. A bad filter can cause it, the filter media collapses and a cheap filter with a poorly designed bypass and you get instant oil starvation. If it was ran low it will show up in the computer logs, the filter he already took apart and it didn’t look to have had a collapse issue, so my bet at this point is the oil pump stopped pumping oil for some reason. But that’s from the limited footage available so we shall see what the future holds.

[@DieselDog358]

Four chains inside timing cover on that thing. One for each bank, one for fuel injection pump(mounted under the intake manifold) and one to drive the oil pump. It also has four camshafts and they are not interchangeable. Make sure you mark them so they get back in the exact same spot. Also, there is different length bolts holding the timing cover on. Don't just pull them out and throw in a bucket. Some bolts are only slightly longer than others. Draw yourself a map and mark them all so you know the exact holes they go back in. Make sure you use Alodine wipes to prep the aluminum before reinstalling. Use the correct sealant or you will be sorry. Also, there is a hole in the cast iron at the rear on the block near the turbo area, it allows for fuel&oil to drain from the valley when testing and it goes into the flexplate housing and could possibly be misdiagnosed as a rear crank seal leaking. Be careful of that. Becareful removing return fuel lines, they look like they should just pull off but they don't, force will break them. Piezoelectric Injectors too. Hydraulic pensioners on the timing gear chains that are spring loaded. Only one camshaft sensor for four camshafts. Hydraulic nonadjustable valve cross heads too (keep them in order). This is a Cummins engine with Bosch fuel system but it is unlike any other Cummins engine. Proceed with caution! God Bless.

If you pull the wiring harness for the injectors off the engine and give it a good look you'll find the harness gets shorted out and it ends up holding an injector open usually cylinder two or cylinder 6 The injector gets held open flooding the cylinder pounding the bearings until there's no tolerances left Pistons have a hard time compressing liquid. Usually it does involve a broken crankshaft. Common issue but it's still less than 2% of all the Cummins 5.0s produced.

@Davesautocenter This is a common issue on all of the cummins engines, most break cranks, they have a class action against Nissan and Cummins, some are saying that it is due to the injector harness being chaffed and that is where the excess heat is coming from. the other massive issue they have is the CP4 pump going out and launching glitter throughout the fuel system causing replacement of all items as if it were to have DEF pumped into the diesel tank.... I am looking into the CPX pump currently as mine just became a Tuens over but doesn't fire issue, and I have 53,000 miles. Im hoping that it isn't anything internal and really hoping that the CP4 pump is fine and it's just my lift pump.
