19+ Cummins Engine Failures, Cracked Blocks, OEM Parts Quality

[@Denis-tu1pd]

This is why anything that moves our country should be made in the usa .

[@albertfetch3503]

If they are retrofitting 18 and older blocks, I wonder if they are still using the 19+ pistons, pins and rods?

[@4xprops457]

That’s why I love my 2001 1/2! Dodge ram 2500 five speed CTD

[@jasondavis9354]

I own a shop that works on semis and heavy equipment. We will never have the parts availability we had before the world shut down. I knew it the second it happened and I’ve been told I’m correct by companies like freightliner and paccar

[@mcminnerly]

Is it possible to change out a 444 7.3 with a 466 in my 2002 school bus.

[@derrickg5612]

Yeah man, go for it.

[@bradsullivan870]

Will the new Cummins motor that is slated to come in the 2025's have the same block?

[@traviscram1364]

Have you done a talk on the LZ0?

[@electrified7309]

I bought my 2022 ram 3500 cummins ho because of reliability, now I think I got screwed by cummins. I might do the hamilton solid lifter conversion but that's 6k and for that price I may be able to just swap the engine if it dies for a 2018- used motor. Makes me mad, should be a recall.

[@jamesbelden8337]

Agreed. Having the same issue with my 2022 3500. Either flat tapper swap or go look at the other two of the big three

[@Arexodius]

I like these guys. Cass and Adam. Good to hear from them! Just to clarify, are we talking about all the 5th gen 6.7 blocks or just the ones with compacted graphite iron, ie high output blocks? Because those are easy to avoid. I know they put lifters in all the 5th gen blocks, instead of flat tappets, but that's not as bad as if a block cracks.

[@electrified7309]

All the 2019+ 5th gen have the graphite blocks and hydraulic lifters and usually fail at about 100k.

[@Arexodius]

@@electrified7309 Ok so all 5th gen blocks should be gently handled, meaning no significant power mods. I'm much more interested in efficiency mods anyway, so I guess they kinda end up in the same category as GM's DD 6.2/6.5 diesel V8:s. Many of those blocks weren't strong, but with intelligent modifications you can get the most out of them with no issues. Would be super interesting to 5.9 swap a 5th gen though... or I guess a 4th gen 6.7...

[@smoovel3222]

Look up Lm diesels they ran 1200 hp on the dyno on a stock 5th gen engine. These blocks are more then strong enough to handle power

[@electrified7309]

@Arexodius Yeah I think if something happened to my 2022 I would try to replace it with a 4th gen motor. But I ordered a bypass oil filter and I'm going to try and make it last as long as I can.

[@electrified7309]

@smoovel3222 I really don't need anymore power I just want reliability but I know what your saying if the blocks can handle that kind of hp th3y should be good. I wonder if they change or upgraded the lifters?

[@bucketheadrox]

53 block part 2

[@RobertHolster1]

Oooh so that's why it was cut short yesterday...thought I had a beer or two too many.

[@rljessee8799]

So all the problems with the 21+Cummins is when power is added to the engine. I’m glad that was openly stated in the episode that explained the issues with the engine the answer seemed vague as if it was a complete failure. But what it did seem like to me was when power was added and I heard it stated once but it was just stated outright.

[@electrified7309]

The hydraulic lifters are going out around 100k miles 2019+

[@RobertHasty]

This affect 2018 HO cummins?

[@WaterandWoodsmen]

No the new light weight block think it’s 2022 or 2023 till present there is a TSB recall to reprogram the pcm to speed up warm up .he had a previous podcast with Choate about it with picture slide of cap threading

[@lilpony001]

@@WaterandWoodsmen its 19+ the main bearing webbing in the block is to weak to hold the main caps ridged in place

[@bdlii]

Whew. Just got a 2018 because everything indicated the design and longevity were well documented. Final year of 4th gen should be as bulletproof as possible in theory.

[@daviddroescher]

ENGINE DELETE KIT, it's its coming. Edison Motors is working on it. There looking for installers/developers for there electric conversation kits . The kit is electric axles ( motor on axle), small batteries, and on bord charging diesel power plant( off hwy emmittions only)

[@BentonL]

I predicted this the day I seen the casting differences. On some of my comments from years ago I said " dont want any cummins18 and up. I said it was failure intended in design.

[@RobertHasty]

What's wrong with a 2018?

[@BentonL]

@@RobertHasty they completely changed how they casted the blocks. Not only did they change the material but they actually changed how thick the block castings were. So pretty much everything with that graphite iron is thinner because they believe the material is stronger. But when you want to go full retard like I do you'll find out that they can't take as much power as their predecessors. When you do some searching on it you'll find out not even asked a question you will be getting spam these results because that's just how these platforms work anymore.

[@Connor_Cripps]

@@RobertHasty Nothing. They're still the flat tappet engines.

[@603Cummins]

@@RobertHasty Nothing is wrong with the 2018s, it's 2019 and up he is talking about. I don't know why but everyone struggles to get the dates right on the change. The 6.7 is functionally identical from it's introduction in 2007.5 up till 2018. In 2019 they changed the 6.7 to a GCI block, changed the lifters from solid to hydraulic and a few other things.

[@RobertHasty]

@@603Cummins yeah I bought the 18 because of the cp4 in the 19s, looks like I lucked out in other ways too.

An other problem everything is made in other countries .the usa is a sales country .

[@jimmungai1938]

I said this before and I’ll say it again I know this would never happen, but if a dealer was the offer me a brand new truck even up for my 91.5 Dodge I tell him give me the cash difference I’m having my engine rebuilt at DNJ machine And I’m just gonna keep putting money in my old Dodge cause I know it’s worth it. This is six in a row.Jim from kennerdell Pennsylvania

[@Binkleytb]

Thanks a lot Jennifer. Should’ve stayed in the kitchen

[@XAllky]

If I get an old 7.3, gotta do all kinds of stuff to get it on the road it’s gonna be 500 a month in replacing worn out parts all the way around the truck….. If I buy a new truck and pop an engine, there’s that…. Not to mention the price of these dieselz

[@stevenberta940]

The 2019 HO SRW was trash.

[@smoovel3222]

You have absolutely no idea what ur talking about

[@1bad335ii]

I’m looking to buy a 2020 ram 3500 dually. Idk what to buy anymore. Will it blow up with proper maintenance done?

[@smoovel3222]

@ Hell no bro, use 5w-40 valvoline premium blue and change every 5k, I have never had an issue out the 5th gen. Even then ford and Chevy use hydraulic lifters too. Aisin is way more stout of a transmission than any 10l slippy in a ford and gm. Very rarely do I see any of the other trucks past 300k. I’ve seen countless Cummins with 500k plus. They’re slower in stock form but tuned up with a 2nd gen swap (turbo) they are freaking rowdy and very reliable except transmission will hurt but so does any transmission with a spicy tune and big turbo.
