Currently I am driving Volvo, but I worked as a tech at KW for a long time and I tell you, there is no such issues with x15. Have not seen single fuel pump failure over the years! Engine noisy and vibrates at idle, but this is about it. Not mentioning aftertreatment system, because this is to certain extent not exactly engine itself. So lets not spread those baseless rumors. Also I wonder how filter clogging could be Cummins issue.
Filter clogging sounds like a company or newer person not putting anti gel in their tanks. I've met a person who never put anti gel in their freight line. Used diesel 911. Said that was for last ditch and should be using anti gel when it's below 20 degrees. I've idled my paccar quite a bit. No apu. Only had to replace the egr aftertreatment once in almost 5 or 6 years. And mine is a used 15 pete. I pretty sure it was factory egr to.
I have seen many problems with the isx15 and x15, the fuel pump gear does have a tendency to spin on the pump shaft. I use loctite 620 when reinstalling the pump gear and I have not had any issues with them.
You've also never seen a truck explode. So by your logic this means no truck ever explodes because you have seen plenty of trucks in the shop that have never exploded or caught fire right?
The Cummins fuel pump issue only pertains to about 2800 engines. Recall notices were sent out a while ago, or you can call in to see if yours is recalled. If so, bring it in and they'll replace it at no cost to you.
In Western Australia we run the X15 in Qaud road trains grossing 210 tonnes. We can't get 12 months without them blowing up. Set at 600hp running 24/7 yet Volvo at 700hp will do 5 years without touching the engine. We all hate the red engines. Wish Cat would come back in to the game as we have many issues in that 1 year mainly after treatment issues not to mention timing gear failure.
i haul milk for a living. im a company driver, my boss was buying paccar engines...... nothing but engine failures and other issues. we since started buying X15 engines, so far from what i can see it's a much better engine. i drive a 2022 T880 18 manual X15 565 hp 1850 tq. i dont own the truck, but as a company driver i really love that engine. milk tankers are very heavy when loaded, and for an emissions engine id say it's a beast. my previous assigned truck was a 2017 T880 18 manual paccar MX13. what an absolute dog.
I have 2 Isx 15 liters and experienced the fuel clogging the filter. I found my cause to be the cold air from the fan and under the truck. So I covered my filter housing with a plastic bag and fastened it in place with tie wraps. I have never had the problem since.
Pollution is the cost of doing business. With all the other cars and pick up trucks running so clean today, leave the big trucks alone. The emission equipment problems have been happening since the very beginning, give us a break.
The x15 fuel pump issue is completely different than the issue with the ISX common rail fuel pump. On the ISX's with common rail fuel injection, you want to rebuild the fuel pump every 250k-300k, mainly to replace the plungers, but it's a fairly cheap rebuild even if you go all in. The x15 fuel pump problem only affects about 2800 engines. What happens is the pump's drive gear slips on the drive shaft so it stops pumping good. It's a less common problem since it's only on certain engines, it has way less potential for blowing up the engine, and the recall replacement should fix it.
I agree with the emissions issues. Deleting is no solution. But (my opinion) the Detroit one box is the most expensive piece of crap out of the lot and the reason I won’t buy Detroit again until it’s gone. I understand they are working on a new system I guess we will see. (Loved my series 60)
I have a 2007 prostar with a cummings. Has a million three km on it. Was working fine two weeks ago. It quit no codes. Towed to shop. Did a turbo in a shop and still not fixed, found a bad fuel sensor. Claimed it was fixed went to pick up 1st load shut down , start and shut down again. Put computer on and had problems communicating with the ecm. Got a used ecm and program by cummings. Ecm ok. Went a couple of kms and quit again. Looking at wirering. No real answers from shop any thoughts?????
I agree I have 7 trucks all of them are Cummins and I have not had any problems. I’ve had the dd15 and those engines are shit I switched over to all Cummins ever since then I’ve been making money. I sold my last 2011 dd15 freightliner junk for 12 grand I was getting million calls for the truck because of the price. And idgaf I did not want tht engine.
Man, in the last 2 days I saw 3 Freightliners stuck on the road. One was on the side of the freeway with a mechanic working on it, one was just on the side of a road in town, and another at a stop light at in intersection. They all had their hoods open not going anywhere.
Our 2020 X15 gels fuel at 25f but generally the fuel supplier's winter mix or bio-fuel percentages. We normally carry 2 sets of filters for everything.
Mine is 2020 i noticed it went up to mark when. Extremely cold. Truck said put gel additive in on the dash. Never shut down or anything. Like 10 to - 10
I'll take a Cummins over a DD anything! All that raggedy DD series engine is a repackaged MBE4000. Thank you for this trash ass bullshit, Diamler-Benz. I'll NEVER buy one.
The fuel pump issues are very real, it is best to rebuild them at roughly 400,000 miles. This is for the CM-2250, CM-2350 and new X-15. Cummins does not build the fuel pumps, I believe Borg Warner does. This is a known issue that no one has been able to solve. Ceramic plungers or steel plungers, they all eventually fail, so rebuild them. And if you ever get a fuel warning light, hit the shoulder and shut her down. The damage can be extensive and expensive, even with the oil circuit being taken out of the newer models. You will still have metal shrapnel in the motor, and more than likely loose all 6 injectors. The fuel gelling? Not an issue that I have ever heard of, may have been a location issue, especially in the temps you were experiencing at the time. Most drivers and O/O do not even know what PowerService is, or any of the other flavors for that matter. The emissions, the Cummins is very easy to maintain if you have a copy of Insite and an Inline 6 reader, both are readily available on eBay for the entire kit, around $250 delivered. Regular EGR Tuneups will keep you out of trouble. Best to remove and clean the EGR Valve and Cooler every few years too. Then the service intervals, 10,000 to 18,000 miles, depending upon usage and conditions. Play around with extended oil changes, and you will be in the poor house when all of that soot catches up to you. In frames start at $28,000. Best to purchase one of the Amsoil Universal remote oil filter kits and run that along with the oil filter on the motor, help keep those soot levels low. Amsoil filters are not required, just find a filter that fits. Then the two main sensors that everyone neglects, the sensors that always has Cummins turbos on back order, the Intake Manifold Pressure Sensor and the Exhaust Back Pressure Sensor. Both are easy to replace in a parking lot with a 10mm socket for the intake sensor, and a 1 1/8 inch socket for the back pressure sensor. Many turbos, at +/- $8000 a pop, are sold to unsuspecting truck owners, quite the racket these shops have going... And when you come back, they nail you for another $4000 +/- when they replace the EGR Cooler... And when you come back again, they tell you you need an in frame... That is how it works folks, when all you needed were two sensors, roughly $300 out of pocket and a few minutes of your time in the parking lot or truck stop to install them. Those blown head gaskets? Drive the truck the way it was engineered to be driven. When under a load, the rpms need to be kept at 1500 and above. Due to the design of the motor, when you lug the motor, say in that 1200 rpm range, under a load, the rods and pistons simply beat the cylinders out of their perch on the tiny ledge they sit upon. Keep the rpms up, stay out of the shop. In frames start at $28,000. The other incentive to own a Cummins, is the fact that they give you all of the manuals for your particular motor via the Engine Serial Number on their website, Cummins QuickServe, all for FREE!. All of the instructions to properly diagnose, repair and even rebuild the motor in your driveway. All of the parts catalogs, specific to your motor, along with torque specs, electrical schematics, sensors along with the needed part numbers for any speciality tools you will need to accomplish the task at hand. No other manufacturer does that. Cummins fan boy here, for good reason. Mine just rolled 1.1 million miles.
@@WayneKerr69420I have a CM-871, old school mechanical. At least on the fuel delivery side, the injectors run off the cam shaft, and have a gear driven pump in the IFSM unit. The rest of the electronics are on there too, just not as bad as these new motors.
I just got a 2019 579 with a Cummins. Switched from Volvo finally.... I had similar issues with my manifold sensors and carried spare ones and anyone without a 10mm wrench and socket should not own a truck. The Volvo enables you to access the trouble codes on the dash and once the problem was fixed the light went out. But My problem was when I had weird problems with it suddenly going into Derate only Volvo could do a forced Regen and reset the code. Luckily I never got stranded on the road because I just unplugged the speed sensor and could still go 65 with less power no speedo or cruise control of course. But I could get home or to a Volvo dealership. My question is can I clear Derate codes with the tools you mentioned. And could you please send me a link to the best ones to purchase that I can carry with me for road side repairs. Thanks I would love to talk to you if you have time Rick Cross 763-744-6086
Signature 600 was the first engine I ever saw run away with less than 10 miles on it cut the block in half signature isx x-15 all boat anchors since Cummins created that junk
Like in liners? Lugging the motor? Running under load below 1500 rpm? Do that, and the #5 liner will break loose. RPMs need to be kept above 1500, if you have an automatic transmission that is set up to lug the motor, have it reprogrammed.
Ok, so no better way to get information about engine problems is from somebody or company that doesn’t run that engine. That said, I’m sure these issue do exist to some extent. But get a driver/mechanic that doesn’t run or like Detroits and you will get the same video. Just take this video with a grain of salt.
Why is he doing a video on Cummins issues and they don’t run Cummins? I’m a Cummins tech making other things. Most of what he’s claimed is hear say and not really seen by most shops. Run whatever engine you want, they ALL have their issues. Also keep in mind ISX15 and X15 are two different motors. Also the ISX15 had dual or single cams. There’s a lot of misinformation being presented here.
A Cummings x15 fuel injection system only returns about a quart of fuel per minute to the tanks or an old 60 series Detroit could return up to gallons and gallons of fuel per minute which in return heats the fuel in the tank
My family have 20 kenworth trucks in Australia, we have never rebuilt a Cummins between 800,000 and 1.2 million kilometres they blow us and get exchanged, but 2006 T650 we sold with a C15 cat, we should have never sold it, the new owner loves it, and we pull 3 trailer roadtrains. Hauling 100,000 litres on diesel 26,400 US galleons, on rough dirt roads. Hence why we only use kenworths.
To bad Daimler ,Bastardized the Detroit this DD15 is a gutless pile. Miss the cummins so much and it got over 1mpg better cause it ran at part throttle all day effortlessly. The Detroit has its tongue hanging out to the floor just to get and keep the load moving lol
I'm Freightliner, Cummins, international certified! @ 500k I noticed Cummins becomes a leak monsters. Leaking everywhere, from oil pan, front crank housing, rear flywheel housing, fuel pump, rear main seal, etc. I understand every company has their flaws! I love Cummins, Strong n reliable but they leak alot!
I feel it's poor maintenance and also I wouldn't really get this from a driver well you can but it's better to get this information from a mechanic who actually works on
Straight line trucker bagging cummins I drive log trucks in New zealand I have used both Detroit an cummins both of them 2021 the x15 far out performes a Detroit In every way cummins has so much more torque which means less gear changes throughout the day just so much easier to drive an unreal power
@@davidwolff8903 Hey David. I see you commented a few times about the Cummins loosing their liners in Australia. Cummins fixed this issue in 2021 after working on the problem for a long time. You should be seeing a much, much longer life now in these very demanding applications.
Max Mileage fuel borne catalyst will solve most of the shortcomings in the design and function of the after treatment system. (Actual user, Alaska winter driver, uncompensated endorsement) 5 years continual use...no detrimental side-effects
Detroits lose fuel pumps quite a bit too, without warning. Same issue as the ford and GM cp4 pumps, it’s a $12k usd job if it fails completely out of warranty. I’ll take my 871 Cummins over any of the new engines.
I believe the x15 economy series is more likely to be problematic and the x15 performance series is pretty good from what I hear. I had my w900 for about 4 years and just recently sold it with 900k kms on it. The only issue I had was clogged fuel filters but switching to 30 micron filters fixed that.
And high pressure pump failure also will be on the horizon with a such course filter. I would try to buy diesel from different supplier, install fuel heater and use antigel
You can’t use a 30 micron filter with out causing issues! What wasn’t being captured in that smaller micron filter is now going through your 30 micron into your fuel system.
I had a brand new 2022 t680 with the x15 on it ,every 3k miles check engine was popping up with the 3 h derate...the codes were showing a high egr pressure.At 25k miles they installed a new software on it to fix the problem,it didn't help so I got rid of it.
Not idling? Haven’t needed rebuild yet? I’m looking at pacaar a but keep seeing comments they are not ad solidly built as Cummins or as reliable, harder to diag, more expensive to fix ect. I’d be interested to hear your experience
Overall Detroit is the best!!! they cost less to maintain and rebuild and offer the same life span as other brands. DETROIT IS THE TOYOTA OF THE TRUCK WORLD. 60 series months and months with out turning it off not even to refuel.
My 2014 pete with the isx15 it never suffered any of those problems, it did suffer from the cam hardening failing that was a problem from 2013-2017 and the biggest thing that killed my truck was being deleted! It had a bad tune, pulling 140,000lbs day in and day out through the canadian rockies did some serious damage. Took 14 months for it to drop valves seats and destroy almost everything. I'd very much so recommend not deleting an emissions truck, instead just don't idle it. I'd take another cummins in a heart beat no question about it, had more power then any other truck I'd driven which includes all the old school favorites 3406, 60 series, dd15, just not the n14 as I'd never had a truck with one yet. My paccar mx13 is dead set reliable, they really are bullet proof engines between 2014-2017 even with questionable maintenance. Just no power and no better fuel economy than I got out of my isx15.
Looks like you telling all this stuff about the wrong engine, worked in KW as a tech for a long time and none of these applied sounds like a Detroit motor issues you are recalling. Sounds like you are hating on the cummins and got paid by Detroit engine 😅
I have a international. It has about 240,000 miles now on. Has had same issues like dd15. The dpf junk. Its a x15. But started about 225,000 having a hot oil smell. Dont see any bad leaks. Seams do mostly when using engine brakes. Looked closely at valve cover etc. Dont see any leaks. Using a little oil that never has before. Any ideas.
Interesting that I have a 2019 Cummins x15, currently with 475,000 miles and have yet to have an engine issue, not even a dpf issue. I did need to have the def manifold replaced in 2021, but I wouldn’t consider that an engine issue.
This man driving a company truck with a Detroit no wonder he talks bad about Cummins iv got a Cummins an Detroit never have I seen these problems with Cummins just like he says don't idle these truck bull shit that's what Regen is for it's simple just like Volvo has clean idle
I have a Volvo with a Cummins and my dpf module catylist blew up and now my truck has been in the shop since may because they don’t have any and they keep telling me they don’t know what to tell me and I’m about to lose my truck to the bank … Cummins suck and will leave you out to dry
Starting the video with a “look how cool I am” vape hit is the cringiest thing I’ve ever seen. Didn’t even bother watching the rest of the video and gave it a thumbs down.
Out of this whole video all I got was fuel pump which isn’t even true clogged filters on cold weather must be the drivers dumping additives clogging the filter and you literally said all trucks have the emisión issue but someone it’s Cummins only even though paccar have more issues than Cummins with the def system
I had 2015 freightliner isx15 1millon 49k miles never had a single problem with the engine except a oil leak . Sold it last week its still got power. Never replaced a fuel pump or the turbo either . Bought it at 600k miles
Can you tell people about the dd15 oil pump o rings fail and loose oil pressure and lockbtje main bearing and rod bearing jajajajajajjaajaj. Tell them that 👏
First it starts putting out smoke and they start leaking around the valve covers..... That's because you've lost your ring seal now you have blow by... Because of the piston rings of the Cummins uses the l-shaped rin.. it's very sensitive to ring seal... Cummins allows for 2 thousandths waer... On the cylinder walls....
10th an 11th gear derate's or bog's down like it's getting no fuel to pull have to slow down or switch gear frustrating what is the issue with this X15 Cummins?
