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.
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.
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.
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.
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.
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.
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)
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
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
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
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!
What I like about the dd15 fuel filter,is that it sits on top of the engine where it's warmer and has a protector cup to keep the cold out.Thats one reason really don't here of fuel waxing in the fuel filter.
I got my x15 2019 and had the same fuel water separator filter issues but I built a Coolant preheated system in and since than I had no issues anymore except the Biodiesel has more than 15% and it’s very cold.Paccar electric heater can’t handle it.
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 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
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.
I got 2018 x15 never had problem like you mentioned. Clogging filter is on driver may be they never heard of winter front that's what they are there for.
2018 X15. 365,000 miles (no APU). I have replaced the EGR Sensor, The Aftertreatment Sensor, and done “routine” maintenance….. average 5.8mpg Love the way it pulls and sounds”. It’s a keeper.
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.
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.
Exhaust in the fuel i stated earlier maybe injector cups type issue maybe it is bad head castings, just a swing in the dark i have never heard of it myself.
The reason the filter gets clogged in cold weather is the secondary filter is usually a 4 or 5 microns absolute filter. And that little bit of gelling clogs it, they also dont push alot of hot fuel back in to the tank
Can I heat that filter if it’s clogged, it’s been warm 2 days but truck still not starting? Changed the water separator filter and the secondary has been changed 1,000 miles ago…..
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.
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?????
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.
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
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
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.
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.
It's not a cummins fuel filter problem it's the paccar filter on the frame that has the problem. Make sure you have the Dafco filter assembly. No problem with my 22 x15 500hp
And to sum up the best engine is one with frequent oil changes and keep the RPMS up while climbing hills to keep the engine cool. Heat and dirty oil kills. I change my oil at 500 hours.
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?
The fuel filter issue might be related to the problem where Paccar was ordering Cummins engines and putting the smaller, cheaper Paccar fuel filter system on them, even though Cummins specifically calls for Davco filter system. And then Paccar wouldn't warranty the problem, falsely claiming that it was Cummins fault.
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.
The issue with the fuel filters is there is exhaust getting into the fuel and Cummins don’t know how. I work at a Peterbilt dealer and it’s been an issue for a while now
@@costa1967 it’s been an ongoing issues they don’t have a fix for. There is a design flaw in the head where there is exhaust getting into the return fuel from the injectors and going back into the tank. They don’t have a fix is what I should of said.
@@Jsizzlydawg I don't know, again I worked till very recent in very busy Kenworth shop and do not remember such an issue with X15. In case this happens issue could be easily troubleshot and fixed by replacing injector seal, possibly cups. In my experience this could happen after injectors were removed and cups were not inspected for debris and cracks, reused seal or injector not torqued to the specs.
@@Jsizzlydawg absolutely impossible... getting Exhaust gas into the fuel...lol... fuelling and Combustion are two different processes with distinct timing. am a diesel tech for over 15years and i have never ever hard exhaust gases leaking into fuel return lines... its like finding a Hippo swimming in the Arctic.
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....
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 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
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
Biggest problem with Cummins is not as close as a biggest problem with DD motors. First, dd is in the Freightliner/western star - two of the worst trucks in the country. As far as Cummins, can be gotten in any chassis. Cummins is the strongest pulling engine out there now. Now, DPF? - yes, they all suck. DD SUCKS with power and drivability, wouldn’t want to have one .
Your opinion is purely that. My Detroit 60 series is the best , smoothest and strongest pulling engine. You can easily search it up that Detroits pull harder up hills. Cummins are tractor engines, there are noisy and vibrate much more than a smooth running Detroit. With a DD16 out performing am ISX15 easily.
@@Prachka1 no. Actually it's because Cummins are built separately from other chassis, as Detroit's are built in House. Also Daimler is much Larger company than Paccar or Cummins and have lower Manufacturing costs. You see Cummins sells engines to Kenworth/Paccar and Volvo for a Profit where as Detroit is built and sold by the Supplier themselves, Freightliner/Daimler. I guess you just don't understand the dynamic of inhouse building. This would be why Cummins has bought Meritor this week. Same reasons.
ryan reinhart, drove them all. Detroit is the weakest of them all, power delivery wise. Again, there is a reason why, primarily, only larger companies where drivers either can’t drive or do not care about driving, have detroits. Outside of 12.7, primarily for electronic reasons, are in demand on the used market. Anything over 12.7 and their demand falls through just like a demand for a Freightliner product, in the used market. People that buy them are either noobs out of schools or starting out. So, take it for what it is. Detroit has displacement and no delivery.
@@Prachka1 😆 funny cause Freighliner has 40% of all truck sales #1 seller and the Detroit 60 series is the top selling engine. Paccar Motors blow head gaskets, Cummins is nothing special either. All these engines are or were owned by GM, there is zero Fundemental difference between them. It's purely brand preference.
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
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.

Had the fuel filter issue with my x15. I had to start keeping 2 filters on me because of how often it happened in cold weather.
It's not x15 veer. It's fuel quality. Not just yours it's on every x15 Pete. 2 filters definitely.

@@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

My 2014 peterbilt with a Paccar mx 13. 1,146,678 miles do not have any problems with it. Running great . 455 hp 13 speed. 336 ratio. I love 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
I’d be getting a 2019 or newer pacaar. I’m not sure what changes have been made since your 2014 model

Please do a video on The People's Convoy. We need numbers!! We are on I 40 East in New Mexico today. Thank you!!
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
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!
Yuuuuup!
What I like about the dd15 fuel filter,is that it sits on top of the engine where it's warmer and has a protector cup to keep the cold out.Thats one reason really don't here of fuel waxing in the fuel filter.
I got my x15 2019 and had the same fuel water separator filter issues but I built a Coolant preheated system in and since than I had no issues anymore except the Biodiesel has more than 15% and it’s very cold.Paccar electric heater can’t handle it.
He doesn’t have a Cummins but he’s an expert on those engines.
Doesn't take much to be informed on a different engine to be very honest
Mines a 2022 and the fuel pump had a leak at 85,000 miles
Mine too!!!
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.
Thanks for watching and sharing!
Switching to 30 micron filter WILL destroy fuel injectors!
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.
Jesus! Your need to go SMALLER like 10um NOT 30um and destruction of the injection system 💵🤡💵
I own a 2020 Pete and can personally tell you you are wrong I have had none of these issues 338,000 x15,605
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
Before you go to bed tonight….check your fuel pump
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.
Thank you, informative and well spoken info!
Thanks for watching and sharing! Really appreciate it.
I got 2018 x15 never had problem like you mentioned. Clogging filter is on driver may be they never heard of winter front that's what they are there for.
Fuel heaters in the tanks for cold weather. The x15 doesn't return enough fuel to tanks to warm them.
2018 X15. 365,000 miles (no APU). I have replaced the EGR Sensor, The Aftertreatment Sensor, and done “routine” maintenance….. average 5.8mpg
Love the way it pulls and sounds”. It’s a keeper.
OMG 5.8 MPG 🤮🤮💵💵💵💵💵💵
My X15 with 570 000 km gets 7.7 mpg average
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
That's cute. Logs in NZ. Come to the Pilbara. Ultra Qauds 210 tonnes. You'll hate the red engines.
@@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.
@@davidwolff8903 just a piss weak auzzy mate
@@MrPizzaman09 that is fantastic to hear. Cheers mate.
I just wish they would bring back the C15 CAT
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.
Exhaust in the fuel i stated earlier maybe injector cups type issue maybe it is bad head castings, just a swing in the dark i have never heard of it myself.
The reason the filter gets clogged in cold weather is the secondary filter is usually a 4 or 5 microns absolute filter. And that little bit of gelling clogs it, they also dont push alot of hot fuel back in to the tank
Thanks for the tip.
Yes it’s the paccar filter.
Can I heat that filter if it’s clogged, it’s been warm 2 days but truck still not starting? Changed the water separator filter and the secondary has been changed 1,000 miles ago…..
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.
On my 2021 had issues with filter , started using fleetguard filters . Problem solve .
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?????
Yikes.... sorry to hear that. I hope it gets resolved soon!
Around 600k the front cover likes to get brittle and dump oil all over the place. I know it’s an issue on CM2350’s but idk on newer X15’s.
Fuel filters are causing clogging with winter blend. Davco filter is solution
My paccar was having that fuel filter issue and I just swapped fuel filter brand and it hasn’t happened since that was 2 yrs ago
About to change out a dd15 with either a 60 series, N14, or ISX15. 🤷🏾♂️
Do I need to calibrate the using a computer?
Possibly, I can't recall though
How about 2015 ISX?? Is it problematic as well??
Check your head gasket. They were going out around 500k. Other then that good power and ran well on fuel milage
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.
Cummins 6BT also have Fuel Pump issue from the begining...comonly they leak diesel to the oil chamber.
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
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
As far as I know, Cummins makes all the aftertreatment systems for Cummins,Detroit and I'm not a 100% about Volvo🙂
I used to work for Volvo and was told by an instructor at one of their schools that cummins makes the after treatment for Volvo too.
I never turn off my engine in cold winter keep it running. Also I use blue def All the time
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.
Do you know anybody that has a Mack anthem semi truck
I had a 2019 anthem, sold it after 2 years.
Oil pressure and cam wearing out should be number 1
I haven't had any of those issues at all on my 2020 X15
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.
It's not a cummins fuel filter problem it's the paccar filter on the frame that has the problem. Make sure you have the Dafco filter assembly. No problem with my 22 x15 500hp
And to sum up the best engine is one with frequent oil changes and keep the RPMS up while climbing hills to keep the engine cool. Heat and dirty oil kills. I change my oil at 500 hours.
Very informative thanks
Glad it was helpful!
I'll stick with the Cummins x15 & the DD 15
I've seen that fuel issue in alot of ism and isb as well
It's true I have this problem with x15
Thanks for watching and sharing!
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?
You good my man the way you explain👍👍👏👏
99% of Cummins engines that I've seen being rebuilt never made it past 750,000 miles.
Someone should take a survey on this.🤔
That's a good idea!
I run Kenworth’s with x15 and signatures 625 before that. Never had issues with either.. PS you Detroit are not Detroits it’s a Mercedes’ engine.
Welp heres another issue, my fuel separator is emptying over night and I cant find the problem
Only issues we have with the isx and x15 is dropping liners around 600k.
What is liners?
The fuel filter issue might be related to the problem where Paccar was ordering Cummins engines and putting the smaller, cheaper Paccar fuel filter system on them, even though Cummins specifically calls for Davco filter system. And then Paccar wouldn't warranty the problem, falsely claiming that it was Cummins fault.
wow that is a crappy response from Paccar
Idle at high RPM. Haven’t had any issues idling high
If I ever buy a truck it's gonna be a DD16.
Thank you for the info .
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.
I agree much of what he was stating is incorrect. Especially about the fuel pump issue. From my understanding that was mainly the 12-16 models
The issue with the fuel filters is there is exhaust getting into the fuel and Cummins don’t know how. I work at a Peterbilt dealer and it’s been an issue for a while now
Have you ever tried to open EDS case and call Cummins support Saying that Cummins do not know how is funny statement.
@@costa1967 it’s been an ongoing issues they don’t have a fix for. There is a design flaw in the head where there is exhaust getting into the return fuel from the injectors and going back into the tank. They don’t have a fix is what I should of said.
Thanks for sharing your experience.
@@Jsizzlydawg I don't know, again I worked till very recent in very busy Kenworth shop and do not remember such an issue with X15. In case this happens issue could be easily troubleshot and fixed by replacing injector seal, possibly cups. In my experience this could happen after injectors were removed and cups were not inspected for debris and cracks, reused seal or injector not torqued to the specs.
@@Jsizzlydawg absolutely impossible... getting Exhaust gas into the fuel...lol... fuelling and Combustion are two different processes with distinct timing. am a diesel tech for over 15years and i have never ever hard exhaust gases leaking into fuel return lines... its like finding a Hippo swimming in the Arctic.
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....
He is working for Detroit don’t worry guys just enjoy the x15 is the best
Will take Cummins/paccar vs Detroit. As a package, freightshaker does not provide anything as good as competition.
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
FRONT AND REAR MAIN OIL SEALS GO OUT AT APROX 300K

@@NorthAmerican-Trucking-News Mine (front) went out at 315k 2016 KW.
Thanks you for your advice gracias
Detroit engines biggest problem is that it’s put in a freightliner…
Heh?
12v, 120V and Coolant Heated DAVCO Fuel Filter is the only way to go on all trucks
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
Ps all poultion controls are off the prostar
Oh?
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
Slide underneath the old girl with a metric adjustable wrench, and check those flywheel bolts...
Detroit is the only engine I have ever blown up. Yes I've put a lot of money in my Cummins, it's left me on the side of the road.
Looks like we have a Cummins hatter
I want an x15 Cummins.
hello well as for the x15 it is a complete redesign from the isx not one part from these engines will interchange get the facts correct
Have a c15 with over 45k hours i high idle the truck when I sleep
Biggest problem with Cummins is not as close as a biggest problem with DD motors. First, dd is in the Freightliner/western star - two of the worst trucks in the country. As far as Cummins, can be gotten in any chassis. Cummins is the strongest pulling engine out there now. Now, DPF? - yes, they all suck. DD SUCKS with power and drivability, wouldn’t want to have one .
Your opinion is purely that.
My Detroit 60 series is the best , smoothest and strongest pulling engine.
You can easily search it up that Detroits pull harder up hills.
Cummins are tractor engines, there are noisy and vibrate much more than a smooth running Detroit. With a DD16 out performing am ISX15 easily.
ryan reinhart , that is why dd15/16 powered chassis are sold at a discount when compared to a Cummins powered one.
@@Prachka1 no. Actually it's because Cummins are built separately from other chassis, as Detroit's are built in House.
Also Daimler is much Larger company than Paccar or Cummins and have lower Manufacturing costs.
You see Cummins sells engines to Kenworth/Paccar and Volvo for a Profit where as Detroit is built and sold by the Supplier themselves, Freightliner/Daimler.
I guess you just don't understand the dynamic of inhouse building.
This would be why Cummins has bought Meritor this week.
Same reasons.
ryan reinhart, drove them all. Detroit is the weakest of them all, power delivery wise. Again, there is a reason why, primarily, only larger companies where drivers either can’t drive or do not care about driving, have detroits. Outside of 12.7, primarily for electronic reasons, are in demand on the used market. Anything over 12.7 and their demand falls through just like a demand for a Freightliner product, in the used market. People that buy them are either noobs out of schools or starting out. So, take it for what it is. Detroit has displacement and no delivery.
@@Prachka1 😆 funny cause Freighliner has 40% of all truck sales #1 seller and the Detroit 60 series is the top selling engine.
Paccar Motors blow head gaskets, Cummins is nothing special either.
All these engines are or were owned by GM, there is zero Fundemental difference between them. It's purely brand preference.
No power going up hills that's depends on what rear eands you got the lower the ratio the more its going to die
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
Seen more trucks with Detroits in them burned down to the frame but you want to hammer Cummings.
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.
Good old 12v Cummins the best
They are junk and parts are on back order . Can’t get sensors for shit and have liner issues all the time . Stick with Detroit or the Volvo/Mack .
