Everything Wrong with the 6.7L Cummins

  • There is no denying that the 6.7L Cummins has been one of the most reliable engines on the diesel market since its release. There really aren't many problems with these engines and most of them go their entire life without experiencing any major failures.

      What about the turbo and all the problems it has from the vnt nozzle cracking to self destruction? What about the oil cooler cracking? What about the China quality tensioner pulleys? What about the DEF freezing in the tank? What about the piss poor wiring harness on the engine and throughout the whole vehicle? What about the front and rear crank seals constantly leaking (front 3 times in 100,000)? I will never advise anyone to buy one that is not deleted before major engine damage occurs.

    As a Cummins guy I can honestly say that they haven't ever gave the public a trouble free engine. 12-24 valves had the killer dowel pin. The 24 valves had the 53 block and then the VP44 that Dodge sent out with a junk lift pump. Then we move to the 6.7 that at first only had one fuel filter and lots of folks had stuck injectors kill their engines. But wait there is more! They moved the grid heater to the intake plenum and over time the high amperage can burn a bolt off in the intake and it can be ingested into the engine. Head gaskts are another problem. What has happened is the engineers and bean counters have tried to make the engine cheaper. It's a shame really. Do you think that Cummins would supply a Ram spec 6.7 to run a stand by generator like the 5.9 would? I doubt it. Do I think Cummins is still superior? Yes. But these little things that can destroy an engine is ridiculous.

      The bolt into the engine happened to me a few weeks ago (11-4-22) in my 2017 Ram 6.7. Completely destroyed the engine (they said) but it still ran. New engine $30k. Although because my warranty was only up by two months and 6k miles they are "helping". It will only cost me $3,000. But I will be renting a vehicle which will cost me a total of about $1,200 and I am with out my truck for a month. All in $4,200 to get my truck back. Here is a list of issues that cost me $$ and the amount I had to pay out of pocket. Water pump froze and destroyed the belt which broke other things ($1,200), Turbo actuator ($1000 put a new one on my self), Turbo ( no out of pocket, had 700 miles left on the warranty, but without the truck for a week, Bolt in the engine ($4,200 with out the truck for a month)... Still waiting for them to fix it. Now I get to wait for the other issues and pay more. Probably the last Ram I own.

    There's another problem I didn't hear mentioned hear; Over time, a bolt in the 2007-current stock RAM 6.7L Cummins grid heater deteriorates, falls into the intake runner, and makes its way to #6 cylinder. When this happens, untold damage happens potentially destroying the engine. Best case scenario, if you're lucky, the bolt can wedge in between the valve and seat. If that's all it is, then the worse possibility is replacing the head if it can't be repaired. Either way, you're talking a lot of money. Thank you for doing this video, it's loaded with great information. Keep that good stuff flowing...

    I love cummins engines, I drive a 2005 Dodge 2500 diesel and it is amazing. I work on 6.7's on Freightliner M2's and Yarddogs. The biggest problems I find are usually Egr Valve/Cooler related and dpf issues a lot on Yard trucks. VGT actuators, and scr's are also problematic. I have seen a couple engines need replaced or major work out of thousands that have gone through the shop. 6.7 engines are great, I believe them to be better than the Chevy or ford equivalent as the Cummins engine is used in a lot of applications. I still prefer a 5.9 common rail over anything though. Just my opinion.

    I sold my 6.7 because I wasn't really towing much and the issues related to soot would only get worse. I bought a F-150 ecoboost I get same turbo performance is what I wanted without the diesel emmision issues. Deleting emissions wasn't an option it basically meant I would lose value can't smog it, or pass state inspections.

    me and my buddy have basically the ford and dodge equivalents of eachother, both are 2019 6.7's and we both had them fully deleted by the dealer, aswell as all the regular things done to them to improve reliability (live in rural alberta, ca) then got tuners from the same company and both of our trucks are around 170k miles. and honestly they both have held up quite well, both have had their share of shop hours, but so far both have been about equal in terms of reliability, I prefer my powerstroke all day but the 6.7 cummins is a nice motor when maintained well

    I had to take my 2020 Ram 2500 in for DPF Filter Full/See Dealer message this past weekend with only 23,700 miles on the truck. I had to take in about 3,000 miles ago back in February for the same thing where a forced regeneration was preformed and only have had two active regen cycles since them. Yesterday morning DPF when from 25% full to 50% to Actice Regen to Filter full in about 15 miles of driving on freeway. Does anyone have any insight as to what is most likely the culprit: not driving truck enough(only pull heavy about 4-6 times a year and I work about 4 miles from my home) or is this a bad DPF that will need to be replace?

    Cummins is pretty reliable but the underrated reliable medium duty in-line 6 navistar dt466e and dt466 are super reliable especially without emissions stuff. The Maxxforce version was alright but with all the “Maxxforce emissions stuff” it doesn’t last long before needing a rebuild.

Not exactly sure why we are having blow by problems. Ring or engine block material problem? We do change the crankcase filter often. But with the blow by problem can only last a couple weeks before clogged filter.

    BTW, the turbo on the Cummins does not have vanes that actually move like the others. It has a sliding ring that moves axially over static vanes to control exhaust flow. It has fewer moving parts and mechanisms, thus is far less complicated. However, that certainly doesn’t mean it’s immune from soot buildup. Emissions.....ruining our engines one mile at a time. The worst part is....the people who came up with these regulations don’t have the slightest clue what any of this is or how it works, infuriating. Thanks for sharing!

    With a 2016 Cummins, I often times I pull over while towing 20k and the 'active' regen is ticking dpf away. So passive is not nearly enough clearly, even when driven hard/towing. I sure wish it were, I'd rarely ever need dpf.

      Here is MY comparison based on the shop I work at. Allison is great for smaller applications...do NOT tune a truck with an Allison to create more torque because it is not a good transmission for power.
      The Ford transmissions are almost just as bad as the Chevy ones but they don't hold up at all.
      The dodge transmissions seem to hold up very well.
      We have rebuild about 4 or 5 dodge transmissions in the 2 years I've worked at my current shop. Chevy we have rebuilt about maybe 150. Ford's....well....we do 3-4 a week...or more....some weeks we do nothing but Ford transmissions. Apart from a warranty on a Duramax head gasket, for the past month the only thing we have worked on is Ford's at the shop...so tired of fords HAHAHAHA
