Worked for Cummins for 6 years. Trust me, if you live in a state that doesn’t do inspections each year. Full Delete and EGR block ASAP, and use your glow plugs regardless of what the temperature is outside when starting. When getting fuel try and buy from stations that semi trucks use. The quality of the fuel is far superior than run of the mill gas station fuel. If you happen to have one with a CP4 pump swap it for a CP3 when you can. The CP4 was designed for European Emission Regulations and much more sensitive to the fuel we use stateside. Any other questions shot me a reply
Thanks for this info buddy....just got me my first diesel '22 2500 Cummins. I'm pretty handy and this helps going forward. Reading up on oil, oil changes/service/etc....Went camping at Brown Co State Park last fall and drove by the Cummins plant in Columbus Indiana. Holy crap that place was HUGE, and town was beautiful!
I had 3 Ram 3500 6.7 Cummins. All 3 over 500K miles. I never have problems. Good service is a must. Old oil kills any turbo or engine no matter what. Idle is the killer for the dpf system. Change crankcase filter regularly, clean egr valve and egr cooler. It’s most a human error (poor maintenance) than an engine problem.
Excellent video man love the fact you give us the issues and then give us somewhat of a description of symptoms and a way to possibly prevent them. Thanks i have a 2022 2500 Cummins absolutely love this truck. They did change back on the CP3 in 2021 but still great info nonetheless.
thank you sir! and yes I obviously need to study up on my fuel pumps but either way that's a good thing that you have the cp3. been running them since like 2003. great pumps rarely have issues! took GM 6 years to figure out the cp4 pumps were garbage.
just 2 corrections: Idling down you truck isnt so much about allowing the turbo to slow down, its about allowing your EGT's to cool down since the turbine housing is very hot, it causes the oil on the bearing to burn off and basically create creosote and making it sticky. And the other one is that sulfur in diesel is not a lubricant, not even a little, however the process of removing the sulfur creating ultra-low sulfur diesel r\also removes certain mercaptans in the fuel that are lubricants.
Fully agree on idling down your diesel. I have an 01 2nd gen with an exhaust probe. I idle my truck until it reaches no more than 320 exhaust temp. Well worth the extra time and pennies to do this. I also add some 2 cycle oil to my tank to give the fuel some more lubricity. Run the truck hard and it will burn it off.
@Thepriest39 you can achieve the same thing by just running at least 5% bio. Restores basically all of the lost lubricity from ulsd. But it doesnt hurt as long as you use a decent oil. Cheap oil leaves behind residues.
Great video. Loved the format of providing symptoms & solutions. Have a 21 RAM 3500 HO Cummins. Most daily drives are less than 15-20 miles but once a week & go for a long drive (30-40 mi) & watch the DPF screen to make sure it’s going through a regen. Then at least twice a month I take it out on the interstate & let it go 75-85 mph, which is where it seems to love to run. Several times per year I’ll drive it on long trips (8-12 hours straight). Very comfortable & the engine performs very well. Plan to start towing w it soon. Great vehicle w a great engine. Thanks again. Several helpful hints, like idling down.
My Owner's Manual says 2 minute idle after normal driving and 5 minute idle after towing. It's not just about giving the turbo time to spool down, it's also about idling down to cool the turbo prior to shutting it off to increase bearing life.
Shutting off a turbo hot will also coke the oil. I don’t shut my engine off until my EGTs (which should be monitored) drop to below 350 degrees. I’m still on the original turbo going on 18 years.
@@rodgraff1782 True, I can’t monitor my EGT’s so I use engine temp. I idle it until I see the temp come back down. That should give the turbo etc plenty of time to cool as idling exhaust is much cooler.
One of the best ways to prevent a Cummins engine from being sooted up is to prevent the soot from being formed in the first place. Max mileage fuelborne catalyst is a proven additive that improves the combustion efficiency thus eliminating the formation of any soot. This result in a much cleaner emissions system and a happier engine
I work for a RTA fleet, the 2008-2010 ISLs are very prone to face plugging their DPF. The after treatment system doesn’t like Bio Fuel either, but you can’t tell the suits nothing when there’s grant money on the line.
The Cummins in my 2017 5500 has been solid so far @ 86k miles. I've only had to drive accordingly for regen once. I let it idle, I always run on tow/haul mode and automatic exhaust brake. Change oil every 5k miles.
seems like you are on top of your truck which is half the battle. I think a lot of people who buy these trucks don't even understand what a regen is. the other thing I would say is that a 5500 is a lot heavier then a 2500 so your engine is probably working harder when it is driving creating more heat which is a great thing for these aftertreatment system!
EL I just got a 17 3500 dually. 40k miles, if you're changing oil every 25 days what kind of miles are you driving? Mine is for a future 5th wheel and I hope to reach that million mile mark. Thanks for the info.
@@paulf1177 25 days of usage, not every month. So sometimes it's every 6 months, even if I only drove 3k miles. The truck gets maxed out by weight, and redline so maintenance is the cheapest expense. Being it is transporting Hazardous Materials, safety is the first concern.
Very thorough overview. I have a 2019 6.7 Cummins. Ram recalled all the 19s and 20s with CP4 pumps. They changed mine at 16,000 kms. Back to old faithful CP3. Haven't put a ton of kilometers on the truck but no issues so far. The emissions system seems to work well and never shows any build up in the DPF. I drive in the city but do regular towing.
I add Power Service Cetene Boost year around to every tank of fuel. It is endorsed by Cummins right on the bottle. They have a winter blend & a summer blend. It cleans the injectors & lubricates all components. It also has Slickdiesel in it which lubricates the pump. Will not void warranty. It only takes ounces each refuel.
I just saw a video from a couple year ago of regional enginedealer and well yes, he talk about filters and looked pretty nervous when said than only 3 or 5 micras particles may damage the system, so! gets scene when came here and heard you talking about the cp4... thanks Nico... cheers from San Lorenzo, Py.
new 2004 dodge 5.9 cummins quad cab laramie long box 4x4 averaging 21 to 23 mpg. fast forward i now have a 2022 ram limited 3500 6.7 quad cab long box 4x4 and get 13.5 mpg. both driven the same loads /conditions. one is emission regulated heavily and the other minimal emission controls so given the fuel mpg difference which one actually puts out more pollution? the older model or the newer one.🤔
Have you seen that the bolt that is used for the electrical connation for the heater grid will rust over time and fall into the number 6 cylinder. I would recommend that when you have that off (intake plate) that you replace with stainless steel bolt to prevent complete failure of the engine. Cheap fix compared to an engine.
Great video. I'm negotiating to buy a used 2008 Freightliner bus with the Cummins 6.7 to convert to an rv. Does 8000 hours and 160k miles sound like a lot?
Cummins switched back to CP3 in 2021. Only 19-20 Cummins have CP4 BUT Ram put out a recall to switch those years back to CP3 as well so your whole CP4 speel was for nothing
My 2022 HO 3500 has been back repeatedly for DPF issues and dumping fuel in the oil. Almost every single mile is towing a 14k toy hauler. I loved my '18 that was flawless, the '22 is too troublesome with these issues and repeated recalls.. Thinking about 7.3 Ford gasser. Going into limp mod over the exhaust and draining an extra gallon of "oil" on oil changes is ludicrous. It's not just Cummins having these problems.
Engineering question: Why don't these engines use the exhaust gases after the DPF for EGR? I mean to prevent sudding up the EGR cooler and EGR valve. Also the exhaust gases should be much cooler after the DPF, so much less cooling needed.
Change them to CNG fuel the system for the Deff gets deleted because u don’t need Deff with CNG & it makes U Green Energy & Good for the Environment. The school would get Tax Credits from the government for being Green Energy.
I have a 2019 and am new to the diesel world... If you have a block heater and can plug it in, use it! It will cut down on your warm up time significantly. Also, beware... When you remote start these trucks and it's cold out they will run a warm up cycle where the engine idles up and the VGT closes to expedite warm up time. At 170°F the VGT is backed off and the truck will remain at high idle until engine temp hits 170°F OR the remote start Timer runs out. At that point the engine just shuts down from 1100-1200 RPM not idle..... Not good for the turbo as mentioned.
I’m glad I bought a power wagon I would never own none of these new diesels I had a 2014 ram Cummins 27 times back to the shop all emission related at 20,000 miles I traded the truck in and never look back and Cummins is one of the best diesels in the world it’s just a shame that they destroyed them with all the emission crap Excellent video is always with great information keep up the good work
you almost can't blame Cummins. They are forced to make these engines with such strict emission protocols and they only get stricter as the years go by. GHG10, GHG14, GHG 17... those are all emission regulations that need to be met by 2010,2014, 2017 and so on. so as the manufacture just gets ahold of the latest emission regulations, the regulation gets tighter and tighter forcing manufacturers to innovate and with innovation comes faults and issues. but yes the diesel engine is no longer the reliable engine it once was.
@@TheGettyAdventures I agree with you 100% the Cummins diesel by itself Is the best motor in the industry in my opinion but like you stated the emissions are killing these motors Because they choke them down and they can’t breathe and Unfortunately it isn’t going to get any better
@@ryanfischer4865 I sold the truck and in New York State if you get caught It’s a $25,000 summons and they impound the truck it’s just not worth it though it is a great idea and the truck will run forever
Great video. Emissions are killing the potential of these Motors as well as gas prices. It's still crazy how the most efficient motor is bogged down. Diesel a cheap fuel to produce and like the hottom of the barrel yet it is the most expensive bc it's efficient.
I had my Turbocharger replaced last week. Trucks makes tinging sounds after shutting engine off that slowly winds down to no sound. Would it be possible to send that video to you to listen to to get your opinion. The sound is coming from new TC i think. dealers says they can not hear it.
2007 235000 miles total, 73000 towing 25000 all up in every state of the country. Total failures. One injector in 2013. One turbo actuator in 2018. Not one other thing. Of course I repaired it as soon as I got it. At 69000 miles the DPF was clogged with ash.
I am a Mercedes Benz certified A tech and I agree with everything you are saying. I will be buying one very soon in that exact configuration because I do 400+ miles a weekend and stopping to refuel with my 5.0 f150 on the i95 re entering ny from New Jersey sets you back ten mins for every minute that you’re stopped at times. The day my warranty expires is the day I delete everything. For off road use only of course.
The turbos should be cleaned at 62.5k miles. There is a port on the turbo to inject solvent. This port was not on the 2007.5 trucks. Those trucks were to be drilled and tapped for the port. Yeah, F that. When I had one, the turbo sooted up and killed the VGT vanes. Thankfully it was under warranty and the dealer replaced the turbo. I then deleted it and never had the problem again. I miss that truck to this day.
it's modders that messed with the system having head gasket issues, also noticed that the bolts tend to stretch on the heads. They should be torqued regularly. Get rid of bolts in general and go with studs with nuts so they act like a spring. remove that EGR, reduce the fuel, add sulfur addative, and you'll have longer life and better performance and less pollutants.
Sounds like the emissions system is causing most of the problems , and that egr system is putting soot in the oil , this eats away at the bearings and contaminates the oil rather quickly .
Is anyone seeing a common theme pretty much every problem with the engine is emissions related so emissions technology in the engine is gonna cause more complexity in the engine, less space in the engine bay, more wear and tear on the parts and potentially could destroy the engine which has to come out of your pocket And less power out of the engine so the way I’m looking at it emissions can go get fucked
Well done. Well organized. Excellent video zooming in and out. Excellent speaking skills make a huge difference! Try to avoid "kindof", "sortof", and "like". Everything is or is not. There is no kindof. At least i am aware of these problems and the causes, symptoms, and prevention. You do make it sound like Ram trucks are seizing up on the road all over every day. There are millions of people pulling rigs with Ram diesel trucks and i have not seen the newspaper say "Ram goes out of business, no body will buy one!" May Ram trucks have 500k miles or more, so there is another side you are not saying except in your last comment. It's hard to imagine school buses are similar to RV towing, since school buses drive realtive short distances with massive starts and stops and idling and weigh alot most than my 7800 lb Ram 2500. Still great knowledge to have about the workings of Cummins Diesels!
#1 DPF/EGR Clogging = Delete. Deletes cost way less than a new emissions system. #2 yes turbo actuators stick due to soot build up and due to non use of exhaust brake. Older 6.7 fords had turbo failures as well. In all respect if you are working the truck. A turbo and manifold isn’t the end of the world and actually better for the truck if upgraded. Maybe to a non vgt if possible. #3 Head gasket failures are more common with more power (being deleted) with no head studs. Not normally a stock issue. #4 is a pretty uncommon issue. The newer trucks emissions systems are decent to say the least. Definitely pre 2013 was more problematic #5 once the egr cooler had totally failed if not under warranty. Deleting the truck is the best and most cost effective option. Not to mention there is a difference in commercial 6.7 Cummins engines and the ones in pickup trucks. #5 as stated below cp4’s are on 2019-2020 trucks and Cummins has switched back to the cp3 for 2021-current. Grab a cp4 disaster kit if you have a cp4 and are worried. As for commercial use and not being able to delete. The cost is what it is for repairs. But for the average day consumer. We are going to have to live with the emissions systems because deletes are becoming hard to do unless you know a guy. ;) Inline 6 mafia 🚜
Thanks for the comment sir! I wish we could delete the hunk of junk they call the emission system but we can't lol it would save so many head aches and help prolong the life of the engine! And yes my fuel pump info was out of date a little, thank you for the correction. But like you mentioned it's hard to find something willing to delete your truck these days. most provinces in Canada have massive fines both your the owner of the truck and the shop who is deleting them. you almost just have to suck it up and be ready to deal with emission issues over the life of the truck.
Head gasket failure, turbo failures and valve problems are because of the back pressure from the crap exhaust filters. I will take a 5.9 Cummins any day over the 6.7. 930,000 miles on my first gen 5.9 with minimal problems. I pull my 16,000 fifth wheel down the freeway at 70 mph and get 15.4 miles to the gallon if I don't have a strong headwind then it drops down to 12.7 to 13.7 depending on the headwind speed. (25+ mph headwinds)
I hate that engine , I blew head gasket, in 3 years 4 turbochargers, super expensive injectors,fuel pump….. egr coolers , last cooler cracked externally 🤦🏻♂️….. you name it I had in Freightliner M2 ……. Will never buy any Cummins product 👎🏻👎🏻👎🏻……. Your videos are fantastic by the way 😃
CP3 is still used on the HO 6.7 I had the problem in my 2019 and so I sold that truck and bought the 2022 Ram 3500 with the HO. I made sure it had the CP3
Hi !, for my 2013 RAM 2500 6.7, do you recommend to always use the "exhaust brake" or "turbo brake" in AUTO, hear arround that helps to keep the turbo cleaner and also gives more life to the brake pads. And what about the grid heater...should I disconnect it ?, normaly when I start the engine don't wait in the RUN ignition stop...just go straight to the START position, and the dash yellow "curl" light just appears for one or two seconds. Thanks!.
What is the most reliable fullsize now? I have been watching your videos for a while now, I am being trapped in the rabbit hole of research! Toyota die hard, not on board with the twin turbo or hybrid. Now I am looking to get back into diesel (had a LB7) and there is so much out there.. Especially when you get into the emissions headache.. Your channel is awesome! Thanks 🤙
Love your stuff. I just bought a '19 Ram 3500. While scrolling through the instrument cluster, I saw a gauge that said that my Diesel Particulate Filter has about a 20% life left. I priced them and they aint cheap. Other than getting it warm, what can I do to "restore" it? (BTW my wife loves your videos too but she said you need a logo. Thank you.
Ram didn’t want to warranty anything on on my Rams I bought 3 in 2 years transmissions electrical fuel system always in limp mode Ram builds junk it’s a shame the USallowed Fiat back in the United States after the garbage they built before they left the country
Cummins went with the CP4 pump because it has a higher pressure, which they needed to comply with the NEW emission standards! Imagine, we are the cleanest industrialized nation in the world yet no one is complaining about the emissions from China and India which are almost 1000 times worse...
Already had the DPF plug and turbo rebuilt. Also the VGT actuator break to the vains sticking. 2009 RAM 6.7. I have also heard of issues with the fuel heater bolt failure. Any know about this
My 2021 67 has a tick, dodge they change the flex plate, pushrods, rocker arms, lifters . And they still can’t find why ….. I’ve told them they should look at the EGR cooler and they said we know what we are doing
In 2021 ram Cummins runs cp3 pumps. That's why I waited until 2021 . The other issue is the bolt on your heater will break and number 6 cylinder eats the bolt.
I had a 21 3500 and towed a 41 ft 5th wheel cross country 4 times and did lots of long drives. Dpf clogged at the 65k mark. Im nervous to go with a ram again
What about the grid heater failure which can take out #6 piston, Chrysler still refuses to build a strong reliable automatic transmission and finally I live in an area where 6.7 owners seem to think the loudest most obnoxious truck wins the race.
Ram did go back to the cp3 in 2021 due to failures... Although you do have options to swap back to the cp3 for the 19/20 model years.. I really questioned their logic on making the switch to the cp4 knowing the problems plaguing the GM Duramax trucks..
from what I read the cp4's are lighter and most likely cheaper to make. and I know in 2019 when they dropped the "updated" Cummins they were very excited about the weight savings.
@@wizard_of_poz4413 yea but 8+ years of garbage reviews and recalls later (many recalls resulting in 4-5k+ in damage) in a competitor why the hell would they go with that platform in the first place knowing all that information... I ask that same question for why the hell Ford went to the cp4 as well..
@@David_TX I mean at the time I wasn't aware anyone used the cp4 when it was adopted in 2011. And I think the draw of going to a pump that puts out 30k psi instead of 23ish or something is pretty huge considering how shitty and filthy these engines run. And Holy shit it's so freaking bad, I've got a 30k mile 2018 that i pulled the cross tube off of and it's disgusting
I'm certainly no diesel mechanic or a mechanic at all for that matter. Anyway I just had a random question. My father has an old 1953 Ford pickup and he runs a lead substitute in the fuel because it needs to cushion the valves.(yes its a gas engine and not a diesel) do you think you would be able to run some sort of lubricant in the fuel system to add lubricating properties to the fuel so the pump doesn't burn up? Like the white bottle of Diesel 911 that we run in the winters?
I have a 2020 ram 3500 dually and at 26ks my fuel pump went on it and it damage my fuel system. Is a recall on the fuel pump. Thank u for all your info
To help burn off the crap in DPF run the truck hard once in a while. Tow as heavy of a load that you can up a steep hill. Your EGT's will get a lot hotter to burn off the crap. I used to work on diesel generators that had a Detroit 4-71. When they got all gunked up I would load test them hard and burn off all of the wet stacking. Kept them working great.
I have a 2012 with 56,000 miles on it . I live 12 miles from nearest town. I've only heard my truck regine one time . Is this normal, as I haven't had any codes or anything.
Have 2 busses with same engine both have high crank case pressure and is pushing oil out of the bypass. Already change crank case filter housing still having high pressure problems any advice
I am fighting a Durastar that keeps derating from a frozen def system. It can be reset with laptop and used. This is in California. When temps drop to 30 degrees or so it sets a code for no. 2 def hose heater open or shorted. It ohmed out ok and was getting 4.5 volts. It appears that the coolant hoses arent getting as warm as the coolant lines to the doser. 91 degrees on the doser lines and 50 degrees at the def tank. Havent seen the def pump yet but I suspect the coolant isnt circulating in def tank. Cummins quickserve shows a valve to open and close coolant lines. I am planning my next move. I could use some ideas.
Question for you have you ever had any issues with the def urea freezing? I've gotten down to some pretty cold temperatures and it's never froze however it was -4° a few weeks ago and we had some issues
You are incorrect in your description of the turbo. Cummins does not use vgt. It is not a variable geometry turbo in the sense it uses veins. Cummins uses a sliding nozzle. The whole set design is far simpler than the architecture that is used by Garrett that is deployed on the dirty Max and the powder stroke(GM &FORD).
When the Gen-5 trucks came out (2019 & up) it made me thankful that I have a completely trouble-free 2016. I can afford a new truck but can NOT afford to have a new $85,000 vehicle that spends most of it's life sitting in the dealer-service lot waiting on back-ordered parts to deal with recalls & warranty repairs.🙄

One of the best ways to prevent a Cummins engine from being sooted up is to prevent the soot from being formed in the first place. Max mileage fuelborne catalyst is a proven additive that improves the combustion efficiency thus eliminating the formation of any soot. This result in a much cleaner emissions system and a happier engine
Kevin Rutherford listener? Me too. I use the catalyst in my 6.7 also.
@@scottM278 the stuff works. it's all about chemistry
Truth, it works. I drove tractor trailer for a living. It’s expensive, but well worth it.
Mines drinking
Dripping coolant from turbo area⁉️
I work for a RTA fleet, the 2008-2010 ISLs are very prone to face plugging their DPF. The after treatment system doesn’t like Bio Fuel either, but you can’t tell the suits nothing when there’s grant money on the line.
The Cummins in my 2017 5500 has been solid so far @ 86k miles. I've only had to drive accordingly for regen once. I let it idle, I always run on tow/haul mode and automatic exhaust brake. Change oil every 5k miles.
seems like you are on top of your truck which is half the battle. I think a lot of people who buy these trucks don't even understand what a regen is. the other thing I would say is that a 5500 is a lot heavier then a 2500 so your engine is probably working harder when it is driving creating more heat which is a great thing for these aftertreatment system!
@@TheGettyAdventures It gets a full inspection every 3 months, oil change averages every 25 days. I own a 2500 as well, but that is a 6.4L.
Tow/haul regime kills transmission by downshifting congratulations my man you’ve been fucked up by manufacture😊
EL I just got a 17 3500 dually. 40k miles, if you're changing oil every 25 days what kind of miles are you driving? Mine is for a future 5th wheel and I hope to reach that million mile mark. Thanks for the info.
@@paulf1177 25 days of usage, not every month. So sometimes it's every 6 months, even if I only drove 3k miles. The truck gets maxed out by weight, and redline so maintenance is the cheapest expense. Being it is transporting Hazardous Materials, safety is the first concern.
Long story short, delete your 6.7 and you're good to go.. lol. Yep, did mine as soon as my warranty was up.
Smart man!
Hotshot EDT fuel additive solves the issue of lubricity
Very thorough overview. I have a 2019 6.7 Cummins. Ram recalled all the 19s and 20s with CP4 pumps. They changed mine at 16,000 kms. Back to old faithful CP3. Haven't put a ton of kilometers on the truck but no issues so far. The emissions system seems to work well and never shows any build up in the DPF. I drive in the city but do regular towing.
We have ISB 8.3 engines and have the exact same issues. Tell the drivers to run them hard in 3rd gear, it has helped with the soot issues!
gets those dpf's nice and hot!
I add Power Service Cetene Boost year around to every tank of fuel. It is endorsed by Cummins right on the bottle. They have a winter blend & a summer blend. It cleans the injectors & lubricates all components. It also has Slickdiesel in it which lubricates the pump. Will not void warranty. It only takes ounces each refuel.
not a bad idea especially for those cp4's! thanks for the comment!
I used to use PS as an additive, switched to Hotshot Secrets. Have a look at it, pretty incredible. I also add about 1oz of ATF every other tank
I just saw a video from a couple year ago of regional enginedealer and well yes, he talk about filters and looked pretty nervous when said than only 3 or 5 micras particles may damage the system, so! gets scene when came here and heard you talking about the cp4... thanks Nico... cheers from San Lorenzo, Py.
So basically get rid of all that emissions garbage and you have an awesome reliable truck.
new 2004 dodge 5.9 cummins quad cab laramie long box 4x4 averaging 21 to 23 mpg. fast forward i now have a 2022 ram limited 3500 6.7 quad cab long box 4x4 and get 13.5 mpg. both driven the same loads /conditions. one is emission regulated heavily and the other minimal emission controls so given the fuel mpg difference which one actually puts out more pollution? the older model or the newer one.🤔
Interesting. Did the 6.7 Cummins in commercial application also switch to hydraulic lifters, or was that just for Ram?
Have you seen that the bolt that is used for the electrical connation for the heater grid will rust over time and fall into the number 6 cylinder. I would recommend that when you have that off (intake plate) that you replace with stainless steel bolt to prevent complete failure of the engine. Cheap fix compared to an engine.
Great video. I'm negotiating to buy a used 2008 Freightliner bus with the Cummins 6.7 to convert to an rv. Does 8000 hours and 160k miles sound like a lot?
Most of those issues can be resolved with a simple delete
The first thing that you do when you have a 6.7 Cummins is that you delete everything never ever a problem again you have 1,000,000 miles engine 😎
well you certainly aren't wrong lol
Cummins switched back to CP3 in 2021. Only 19-20 Cummins have CP4 BUT Ram put out a recall to switch those years back to CP3 as well so your whole CP4 speel was for nothing
My 2022 HO 3500 has been back repeatedly for DPF issues and dumping fuel in the oil. Almost every single mile is towing a 14k toy hauler. I loved my '18 that was flawless, the '22 is too troublesome with these issues and repeated recalls..
Thinking about 7.3 Ford gasser. Going into limp mod over the exhaust and draining an extra gallon of "oil" on oil changes is ludicrous.
It's not just Cummins having these problems.
Super loud intro that disturbs family followed by quiet dialog that I cannot hear. Just giving feedback… but it is annoying.
Thank you, will tune it down a little
Engineering question: Why don't these engines use the exhaust gases after the DPF for EGR?
I mean to prevent sudding up the EGR cooler and EGR valve.
Also the exhaust gases should be much cooler after the DPF, so much less cooling needed.
My 2019 had a recall on the fuel pump, it took a year to get after I was notified, it is now the CP3.
I love my 1st Gen! 1993 W350 Manual!
Regards Alex.
Wonderful your video and comments!
Your experience is really highlighted; congratulations!
Big hug from CDMX!
Change them to CNG fuel the system for the Deff gets deleted because u don’t need Deff with CNG & it makes U Green Energy & Good for the Environment. The school would get Tax Credits from the government for being Green Energy.
I have a 2019 and am new to the diesel world...
If you have a block heater and can plug it in, use it! It will cut down on your warm up time significantly.
Also, beware... When you remote start these trucks and it's cold out they will run a warm up cycle where the engine idles up and the VGT closes to expedite warm up time. At 170°F the VGT is backed off and the truck will remain at high idle until engine temp hits 170°F OR the remote start Timer runs out. At that point the engine just shuts down from 1100-1200 RPM not idle.....
Not good for the turbo as mentioned.
I’m glad I bought a power wagon I would never own none of these new diesels I had a 2014 ram Cummins 27 times back to the shop all emission related at 20,000 miles I traded the truck in and never look back and Cummins is one of the best diesels in the world it’s just a shame that they destroyed them with all the emission crap Excellent video is always with great information keep up the good work
you almost can't blame Cummins. They are forced to make these engines with such strict emission protocols and they only get stricter as the years go by. GHG10, GHG14, GHG 17... those are all emission regulations that need to be met by 2010,2014, 2017 and so on. so as the manufacture just gets ahold of the latest emission regulations, the regulation gets tighter and tighter forcing manufacturers to innovate and with innovation comes faults and issues.
but yes the diesel engine is no longer the reliable engine it once was.
@@TheGettyAdventures I agree with you 100% the Cummins diesel by itself Is the best motor in the industry in my opinion but like you stated the emissions are killing these motors Because they choke them down and they can’t breathe and Unfortunately it isn’t going to get any better
Then remove the emissions 😉
@@ryanfischer4865 I sold the truck and in New York State if you get caught It’s a $25,000 summons and they impound the truck it’s just not worth it though it is a great idea and the truck will run forever
Great video.
Emissions are killing the potential of these Motors as well as gas prices. It's still crazy how the most efficient motor is bogged down. Diesel a cheap fuel to produce and like the hottom of the barrel yet it is the most expensive bc it's efficient.
I had my Turbocharger replaced last week. Trucks makes tinging sounds after shutting engine off that slowly winds down to no sound. Would it be possible to send that video to you to listen to to get your opinion. The sound is coming from new TC i think. dealers says they can not hear it.
in your experience have you come across a engine code p026b injection timing performance. i have a 2020 3500 ram ho
Thanks for the video looking at a 5500 cab chassis since I can seem to get one for cheaper than a 3500....
2007 235000 miles total, 73000 towing 25000 all up in every state of the country. Total failures. One injector in 2013. One turbo actuator in 2018. Not one other thing. Of course I repaired it as soon as I got it. At 69000 miles the DPF was clogged with ash.
Thank you for the great Information on the Cummins engine, mine is the 2017 3500 ram ,so far 72000 miles. So far great truck!
Thats awesome to hear!
On the ram pickups you are to service or clean your egr and egr cooler every 67500 miles . I service mine every 60000 miles.
My 2021 has a cp3. Update your info.
I am a Mercedes Benz certified A tech and I agree with everything you are saying. I will be buying one very soon in that exact configuration because I do 400+ miles a weekend and stopping to refuel with my 5.0 f150 on the i95 re entering ny from New Jersey sets you back ten mins for every minute that you’re stopped at times. The day my warranty expires is the day I delete everything. For off road use only of course.
The turbos should be cleaned at 62.5k miles. There is a port on the turbo to inject solvent. This port was not on the 2007.5 trucks. Those trucks were to be drilled and tapped for the port. Yeah, F that. When I had one, the turbo sooted up and killed the VGT vanes. Thankfully it was under warranty and the dealer replaced the turbo. I then deleted it and never had the problem again. I miss that truck to this day.
it's modders that messed with the system having head gasket issues, also noticed that the bolts tend to stretch on the heads. They should be torqued regularly. Get rid of bolts in general and go with studs with nuts so they act like a spring. remove that EGR, reduce the fuel, add sulfur addative, and you'll have longer life and better performance and less pollutants.
The CP4 only came is the 19 and 20. The 21 went back to the CP3. The 2019 and 2020 has been recalled and are getting the CP3.
Sounds like the emissions system is causing most of the problems , and that egr system is putting soot in the oil , this eats away at the bearings and contaminates the oil rather quickly .
Is anyone seeing a common theme pretty much every problem with the engine is emissions related so emissions technology in the engine is gonna cause
more complexity in the engine, less space in the engine bay, more wear and tear on the parts and potentially could destroy the engine which has to come out of your pocket
And less power out of the engine so the way I’m looking at it emissions can go get fucked
Well done. Well organized. Excellent video zooming in and out. Excellent speaking skills make a huge difference! Try to avoid "kindof", "sortof", and "like". Everything is or is not. There is no kindof. At least i am aware of these problems and the causes, symptoms, and prevention. You do make it sound like Ram trucks are seizing up on the road all over every day. There are millions of people pulling rigs with Ram diesel trucks and i have not seen the newspaper say "Ram goes out of business, no body will buy one!" May Ram trucks have 500k miles or more, so there is another side you are not saying except in your last comment. It's hard to imagine school buses are similar to RV towing, since school buses drive realtive short distances with massive starts and stops and idling and weigh alot most than my 7800 lb Ram 2500. Still great knowledge to have about the workings of Cummins Diesels!
Its called oil coking, due to high exhaust gas temperature!
Can the CP4 be switched out or not?
#1 DPF/EGR Clogging = Delete. Deletes cost way less than a new emissions system.
#2 yes turbo actuators stick due to soot build up and due to non use of exhaust brake. Older 6.7 fords had turbo failures as well. In all respect if you are working the truck. A turbo and manifold isn’t the end of the world and actually better for the truck if upgraded. Maybe to a non vgt if possible.
#3 Head gasket failures are more common with more power (being deleted) with no head studs. Not normally a stock issue.
#4 is a pretty uncommon issue. The newer trucks emissions systems are decent to say the least. Definitely pre 2013 was more problematic
#5 once the egr cooler had totally failed if not under warranty. Deleting the truck is the best and most cost effective option. Not to mention there is a difference in commercial 6.7 Cummins engines and the ones in pickup trucks.
#5 as stated below cp4’s are on 2019-2020 trucks and Cummins has switched back to the cp3 for 2021-current. Grab a cp4 disaster kit if you have a cp4 and are worried.
As for commercial use and not being able to delete. The cost is what it is for repairs. But for the average day consumer. We are going to have to live with the emissions systems because deletes are becoming hard to do unless you know a guy. ;) Inline 6 mafia 🚜
Thanks for the comment sir! I wish we could delete the hunk of junk they call the emission system but we can't lol it would save so many head aches and help prolong the life of the engine! And yes my fuel pump info was out of date a little, thank you for the correction.
But like you mentioned it's hard to find something willing to delete your truck these days. most provinces in Canada have massive fines both your the owner of the truck and the shop who is deleting them. you almost just have to suck it up and be ready to deal with emission issues over the life of the truck.
👍🏽👌🏽
You never mentioned. The lifter is another main failure. On new models.
all the stuff that breaks has nothing to do with the engine running and is EPA junk
Head gasket failure, turbo failures and valve problems are because of the back pressure from the crap exhaust filters. I will take a 5.9 Cummins any day over the 6.7. 930,000 miles on my first gen 5.9 with minimal problems. I pull my 16,000 fifth wheel down the freeway at 70 mph and get 15.4 miles to the gallon if I don't have a strong headwind then it drops down to 12.7 to 13.7 depending on the headwind speed. (25+ mph headwinds)
I have a 2014 2500 RAM 6.7. It’s not my first Cummins! I am selling the truck as I don’t have confidence that it won’t leave me somewhere on trips!
My 21 5500 has the CP3. Coworker's 19 has the CP4, and is waiting to perform the recall that changes to the CP3.
I hate that engine , I blew head gasket, in 3 years 4 turbochargers, super expensive injectors,fuel pump….. egr coolers , last cooler cracked externally 🤦🏻♂️….. you name it I had in Freightliner M2 ……. Will never buy any Cummins product 👎🏻👎🏻👎🏻……. Your videos are fantastic by the way 😃
CP3 is still used on the HO 6.7 I had the problem in my 2019 and so I sold that truck and bought the 2022 Ram 3500 with the HO. I made sure it had the CP3
Hi !, for my 2013 RAM 2500 6.7, do you recommend to always use the "exhaust brake" or "turbo brake" in AUTO, hear arround that helps to keep the turbo cleaner and also gives more life to the brake pads. And what about the grid heater...should I disconnect it ?, normaly when I start the engine don't wait in the RUN ignition stop...just go straight to the START position, and the dash yellow "curl" light just appears for one or two seconds.
Thanks!.
Thanks for the info, I love Utube
What is the most reliable fullsize now? I have been watching your videos for a while now, I am being trapped in the rabbit hole of research! Toyota die hard, not on board with the twin turbo or hybrid. Now I am looking to get back into diesel (had a LB7) and there is so much out there.. Especially when you get into the emissions headache.. Your channel is awesome!
Thanks
🤙
Love your stuff. I just bought a '19 Ram 3500. While scrolling through the instrument cluster, I saw a gauge that said that my Diesel Particulate Filter has about a 20% life left. I priced them and they aint cheap. Other than getting it warm, what can I do to "restore" it? (BTW my wife loves your videos too but she said you need a logo. Thank you.
Have you ever had the dreaded heater grid bolt failure on one your 6.7s or the grid itself disintegrating?
We have been very lucky with our fleet! since I've worked here no we haven't had any of those failures.
Ram didn’t want to warranty anything on on my Rams I bought 3 in 2 years transmissions electrical fuel system always in limp mode Ram builds junk it’s a shame the USallowed Fiat back in the United States after the garbage they built before they left the country
Cummins went with the CP4 pump because it has a higher pressure, which they needed to comply with the NEW emission standards! Imagine, we are the cleanest industrialized nation in the world yet no one is complaining about the emissions from China and India which are almost 1000 times worse...
In california there is 0 sulfer in our diesel fuel .
Already had the DPF plug and turbo rebuilt. Also the VGT actuator break to the vains sticking. 2009 RAM 6.7. I have also heard of issues with the fuel heater bolt failure. Any know about this
My 2021 67 has a tick, dodge they change the flex plate, pushrods, rocker arms, lifters . And they still can’t find why ….. I’ve told them they should look at the EGR cooler and they said we know what we are doing
In 2021 ram Cummins runs cp3 pumps. That's why I waited until 2021 . The other issue is the bolt on your heater will break and number 6 cylinder eats the bolt.
In other words ( to err is human to REALLY screw thing up involve the federal government)
Sweet. Most of these issue can’t happen on my truck. 2011 2500 that’s been deleted for years. Only 113k miles.
I had a 21 3500 and towed a 41 ft 5th wheel cross country 4 times and did lots of long drives. Dpf clogged at the 65k mark. Im nervous to go with a ram again
Would the "disaster prevention filter" for a Ford super duty work on the Cummins engine.
Im about to buy a used 2022 ram 2500 6.7 long horn do you have a video explaining what to look for when buying a ram?
What about the grid heater failure which can take out #6 piston, Chrysler still refuses to build a strong reliable automatic transmission and finally I live in an area where 6.7 owners seem to think the loudest most obnoxious truck wins the race.
Hi, just curious why you have a gas engine truck? You obviously know the 6.7. Thanks
Ram did go back to the cp3 in 2021 due to failures... Although you do have options to swap back to the cp3 for the 19/20 model years.. I really questioned their logic on making the switch to the cp4 knowing the problems plaguing the GM Duramax trucks..
Emissions. So probably some government bullshit
from what I read the cp4's are lighter and most likely cheaper to make. and I know in 2019 when they dropped the "updated" Cummins they were very excited about the weight savings.
That and the cp4 puts out more pressure
@@wizard_of_poz4413 yea but 8+ years of garbage reviews and recalls later (many recalls resulting in 4-5k+ in damage) in a competitor why the hell would they go with that platform in the first place knowing all that information... I ask that same question for why the hell Ford went to the cp4 as well..
@@David_TX I mean at the time I wasn't aware anyone used the cp4 when it was adopted in 2011. And I think the draw of going to a pump that puts out 30k psi instead of 23ish or something is pretty huge considering how shitty and filthy these engines run. And Holy shit it's so freaking bad, I've got a 30k mile 2018 that i pulled the cross tube off of and it's disgusting
Does this only applies to the 2500 ? Isn't the 6.7 Cummins exactly the same one on the 3500?
I'm certainly no diesel mechanic or a mechanic at all for that matter. Anyway I just had a random question. My father has an old 1953 Ford pickup and he runs a lead substitute in the fuel because it needs to cushion the valves.(yes its a gas engine and not a diesel) do you think you would be able to run some sort of lubricant in the fuel system to add lubricating properties to the fuel so the pump doesn't burn up? Like the white bottle of Diesel 911 that we run in the winters?
I have a 2020 ram 3500 dually and at 26ks my fuel pump went on it and it damage my fuel system. Is a recall on the fuel pump. Thank u for all your info
My 2021
Cummins oil change interval is every 15,000.
To help burn off the crap in DPF run the truck hard once in a while. Tow as heavy of a load that you can up a steep hill. Your EGT's will get a lot hotter to burn off the crap. I used to work on diesel generators that had a Detroit 4-71. When they got all gunked up I would load test them hard and burn off all of the wet stacking. Kept them working great.
I have a 2012 with 56,000 miles on it . I live 12 miles from nearest town. I've only heard my truck regine one time . Is this normal, as I haven't had any codes or anything.
Is it possible to delete a 6.7 Cummins Isb on a 2009 school bus?
Yeah it’s possible but is it legal? Absolutely not.
Have 2 busses with same engine both have high crank case pressure and is pushing oil out of the bypass. Already change crank case filter housing still having high pressure problems any advice
I am fighting a Durastar that keeps derating from a frozen def system. It can be reset with laptop and used. This is in California. When temps drop to 30 degrees or so it sets a code for no. 2 def hose heater open or shorted. It ohmed out ok and was getting 4.5 volts. It appears that the coolant hoses arent getting as warm as the coolant lines to the doser. 91 degrees on the doser lines and 50 degrees at the def tank. Havent seen the def pump yet but I suspect the coolant isnt circulating in def tank. Cummins quickserve shows a valve to open and close coolant lines. I am planning my next move. I could use some ideas.
Question for you have you ever had any issues with the def urea freezing? I've gotten down to some pretty cold temperatures and it's never froze however it was -4° a few weeks ago and we had some issues
You are incorrect in your description of the turbo. Cummins does not use vgt. It is not a variable geometry turbo in the sense it uses veins. Cummins uses a sliding nozzle. The whole set design is far simpler than the architecture that is used by Garrett that is deployed on the dirty Max and the powder stroke(GM &FORD).
That’s the reason they make diesel fuel additives. To provide more lubrication for the low sulfur fuels. It should be routine for diesel owners.
Sweet only issue I really need to worry about is the vgt actuator lol. Aswell I guess as head gasket. Fuck them egr dpf shit.
What about the heater grid failure with engine damage. I have 2015 2500 6.7
2012 3500 cummins dually a good option to you guys?
When the Gen-5 trucks came out (2019 & up) it made me thankful that I have a completely trouble-free 2016.
I can afford a new truck but can NOT afford to have a new $85,000 vehicle that spends most of it's life sitting in the dealer-service lot waiting on back-ordered parts to deal with recalls & warranty repairs.🙄
especially now my god the amount of back ordered Cummins parts right now is wild.
I watched about 3 mins max and my suspicion of a young inexperienced diesel mechanic came through
I think 2021 and newer have the CP3 fuel pump. And use Amsoil will help too with oil pollution and help with turbo where.
