Looking at a 2022 ram 6.4, new to world of ram

[Cpalf1]

Looking at trading in my 2021 gmc sierra 1500 with 5.3 because the lifter failures in these things are unreal. Also has a sticky first to 2nd shift which gm considers normal. Its enough to spill your coffee!

Anyways is there any thing I should watch for good and bad please! Hoping to look at it tomorrow. I have owned a couple 6.2l f250s that have been rock solid and they are my fall back but the rams are beautiful inside!

I do a TON of idle hours(I work in my truck 14hrs a day often idling 2hrs at a time before moving truck, vehicle runs whole time) drive in all conditions in backroads(pipeline work). Any known engine/transmission/other issues to beware of? Thanks in advance!

I would strongly suggest the Ford F250 with the 7.3L Godzilla in your case. The 6.4L has some documented lifter/cam failure issues that your long idle times may not be helpful with.... The 7.3L Godzilla is a newly designed HD gas pushrod engine that will likely be the most reliable choice long term.

I just traded in my 2020 f250 with a 7.3 on a 2022 ram 2500. If I spent the amount of time you do in my vehicle I would definitely get the Ram. The Ford shifts so bad I put a tuner on it within a month, it also rides like a log wagon compared to the dodge. As for as the Hemi lifter problem, they put Hemi's in everything. I have watched dozens of videos on the lifter issue. From what I learned is its in high mileage vehicles. my person opinion is keep good fresh oil and it probably won't ever be an issue. My one complaint with Ram is they lock the computer and it cost a lot to tune the truck. The Ram shifts so nice and drives like a half ton. I am really happy with my Ram

What do you mean, "My one complaint with Ram is they lock the computer". Is that different than the alfaobd having the ability to set different parameters in the computer?

Use a tuner when you change parts on your truck. you either have to buy a new eco or have your eco unlocked so you can tune it.

The Fords don't ride quite as nice and the interiors are not as nice, but the aluminum bodies and beds won't ever rust out and the 7.3L V8 is easily the best of the current gas HD offerings. It has no cylinder deactivation, no engine auto stop-start, no direct fuel injection, and only one camshaft. It also is really the only gas capable of towing a significantly heavy load. The 10 speed is reliable but not as smooth as the 8 speed in the gas HD RAM trucks. I also think the RAM trucks are better looking. The HD Silverado, at least in lower trims, is downright ugly on the front end.

Agree with all of this and would add that if I was doing excessive idle hours, I would shy away from the hemi. There have been plenty of low mileage failures reported. Whether it is idle time, low oil pressure, oil quality or service interval related, is debatable. I am curious why the OP wants an HD truck when his current truck is a 1500. If not hauling heavy, there seems to be more choices in the 1500s than the 2500s.

Lots of guys just prefer the HD trucks for their higher ride height. The HD's also offer a little better off road capability simply due to increased ground clearance. At least this guy doesn't want a diesel just to ride around with. I mean hey, if you have lots of money do what you want, but if you don't plan to tow heavy loads, a diesel probably isn't the best choice.

I like the design of the Hemi engine, and while the MDS is an interesting and functional concept, I'd prefer it to not exist.

I don’t get the hate of the MDS, doesn’t bother me personally, and it is easy to lock it out... I love my 6.4.

People are only concerned with the MDS system due to the fact that it may cause engine longevity issues as mileage adds up on the truck. Right now, any fuel savings is of great benefit to the owner, and MDS can be disabled quickly unlike the GM trucks. Those things are pluses.

.02 here......I have a 2500HD Limited gasser megacab. I do not tow or really haul anything over the bedrails. I came from a 2015 GMC 1500 Sierra...got 160k out of the GMC stock transmission but also no DoD issues either <knock on wood>. It was a handed down to my son. I have a 6.1L SRT engine in my wife's '09 300C SRT8. It wiped a lobe at 140k and I replaced the cam and lifters with a Spartan cam and hellcat lifters and that does just fine. I ran Schaeffer's oil in the SRT since 6k miles and really have no gripes on the longevity. There was no MDS in the 6.1L from factory.

I could not stomach the looks of any of the 1500's on the market and the 2500HD models in GM were bad from all sides. The GMC was tolerable, but the interior lacked so much at the time of my order (last Aug.) that my seat time staring at a Limited interior vs whatever GM offered totally outweighed any tolerance I had for the GMC. The 2022 GM is better, but I am totally happy where my a$$ is sitting today.

Mileage sux. $108 fillup is not great if done twice a week tho.

Also to add...the SRT cam didn't show signs of issue until it was taken out of daily driver status and ended up as a toy on weekends. I fear that could have caused the issue more than driving it 33k / yr.

 

[troverman]

Wear on the cam is caused by the cam actually rotating, so not driving it should not have caused the problem. Wear can occur on engine components for quite awhile and there is a certain tolerance to that. Seems like the Hemi engine is more susceptible to cam wear than other engines; more frequent oil changes is likely the best elixir but even that won't solve it entirely. As for your GMC, it had the updated AFM and these engines were less likely to have AFM problems compared to the original generation from 2007-2013. In my opinion, AFM aside, the LS engine is probably the best engine on the market in terms of total reliability, longevity, and ease of repair. They don't make the most power, but they are great motors. I hate the current Silverado HD styling as well, particularly the lower trims.

 

[ClawSS]

Yeah, my take on the SRT was more on the sitting for time without a daily oil bath. The lifter needle bearings were the culprit on the cam wear. Cyl. #3 on Exhaust (I think) was the failure point. The other lifters and lobes were actually pretty good considering the mileage.

 

[troverman]

So weird how just one gets taken out while the others remain basically totally fine. Roller lifters seem like a good idea but its also another failure point.

I would take a look at this video, this guy works at chrysler as a tech (or did, dont remember lol). He is doubtful about MDS being the cause of this issue. skip to 23:00 or so.

I built a 350 Chevy with flat tappet cam and lifters. After 7K miles, I wiped the exhaust lobe and lifter on the #7 cylinder. All others were fine. Been building motors for years and this was the first time I ever had one wipe the cam. Rebuilt the motor and went roller cam. No issues so far after 10K miles.
