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.

@Dennismelnychuk Год назад

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.

@Derek-pd4fc 2 года назад

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.

@tonyozanich3760 Год назад

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.

@dukenukem1031 Год назад

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.

The only real problem with 6.7 is people who use it as a payment princess, the turbo will soot. If you buy one pull with it, that's what it's ment to do.

I worked for Chrysler for about 10 years and didn't see any head gasket failures. The CP4 pump did grenade a few fuel systems. The turbos use a sleeve that controls how much air goes around the vanes, the vanes themselves don't actually move. Only other issue ove seen that you didn't mention is the intake air heater grid bolt becoming loose and falling into the engine. Banks fixed that issue with their monster ram intake.

I run water and or methal injection on my 6.7, no build up what so ever, keeps the EGR and cooler clean all the time, never had a single issue with anything and on alcohol it makes more power super cheap.

Question, this same 6.7 liter Cummins is offered in motor homes, in a Super C motor home weighing around 30,000 lbs, will you have this issue or will the engine work more efficiently to disallow these issues?

@jponyboyace 2 года назад

But we can agree Allison along with Cummins are unbeatable!!!!

The one thing I will tell anyone who wants to delete/ do power adders. Install ARP head studs. You will blow the head gasket pretty easily.

When I was in our garden I thought about the 6.7 Cummins and I’m just 12 but I take a big interest in all trucks I studied about trucks for 5 years and from the Cummins diesel family the 6.7 Cummins is by far the worst,I’m more of a Ford 6.4 guy but the 5.9 Cummins is reliable at the most but the 6.7 Cummins May put out the most power and torque,it doesn’t me it puts out the most reliability over all great video ,the 5.0 is nice as well

A rear coolant reroute helps a ton with the head gasket issue

@specforged5651 2 года назад

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!

The grid heater bolt and nut can corrode and fall into the intake. It will damage a piston and head.

Im a school bus tech. Ive mostly found that engine blow by is a major problem with the 6.7. Clogs the EGR cooler and valve in a few months. This is a problem near 200,000mi. 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.

Business owner pulling pup trailer for landscaping business (boulders) Owned them all. 6.7Cummins best engine by far, not even close. Ram transmission even held out better than Superduty 250. I had really bad luck with continuous DPF issues with my Duramax's (Isuzu). Yep, Ford headgaskets were the last straw with me.

@garygriffiths5384 Год назад

The head gasket is no longer an issue, unless pushed over 600Hp then it does need studs. Past issues were caused by imperfections made by the block makers

Turbo issues are more likely to happen with the actual actuator within the module. Causing a turbo communication Failure which is a $6600 bill at dealer for new turbo with the same faulty electric motor. City Diesel replacement is awesome and costs $1000. Just did mine. Nice vid!

@@alittlebitofeverything5090 honestly, I had driven with a bad VGT for so long that it felt fine until I got a new one. If you have any type of monitoring system, look at the VGT position sensor and that will tell you all you need to know. Otherwise, it will feel fast up top and slow down low or vice versa. Or if it's not making boost at all you've got an issue

6.7 Cummins could be a reliable engine. Because it's less problematic parts and that's what I'm going to say it. The thing I love about the 6.7 Cummins, is the 2nd gen swap. The second gen swap comes from 94-02 turbo with the S300-S400 turbo and the manifold, it fits for the 07.5-09 3rd gen, 10-18 4th gen and especially for the 19-current 5th gen.

@dougn6465 Год назад

@B B spools the turbo better, lower EGT, and best of all sounds better

@dougn6465 Год назад

@B B my understanding, the 2nd gen spools the turbo off the middle cylinders instead of the rear cylinders. Which also allows u to run a bigger turbo as it’s not stuff under the firewall. 2nd gens have more of a tractor sound then the newer trucks

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?

@bucketheadrox Год назад

My main advice with the 6.7 is monitor the egt and ever now and again get it up at 1600-1700 rpm for a while and let the exhaust brake thump you down from a decent speed. I usually just limit the gears and in the hills I run I stay at a good egt and rpm. That way I know I'm atleast using more fuel to keep things cleaner. I may figure something else out but for now I just drive it a type of way.

@gallo71359 9 месяцев назад

Injectors is another thing to keep in mind. If left unnatended it can lead to scorched pistons on this 6.7s.
