GM V8 gas engines are junk now

[Vaquero]

Ram is going to a straight 6 turbo to replace the 5.7 hemi.
Supposed to produce lots of torque.

both dodge and ford have abandoned the small diesel in their half ton trucks. Only gm remains with a small diesel as an option.

I REMBER LOTS OF NISSAN ISUZU AND MAZDAHAD INNLINEFOUR CYLINDER DISEL ENGINES

I never knew Ford had a half ton diesel option.

I knew Ram had mixed reviews on their Eco Diesel
Not sure who made that

The GM 3.0 Duramax is reporting good fuel economy but there are expensive potential maintenance and repair items on those also

A half ton trucks sticker price runs from $40-70,000 or more

The damn engines and transmissions won't last 100k miles before needing magor repairs and thats not worth it anymore.

Anything that is named "eco" sucks.

It’s because gm produced the 3.0 while the 2.8 was produced by Isuzu and having owned one I can say it gave me almost 90k trouble free miles before trading it. Would still be going fine I’m sure.

FUEL QUALITY IS CRITICAN THE DURAMAX ENGINES

Yes sir I bet it is!
With the 60,000 psi injection rails on some of these modern trucks I can only imagine

Any water in the system can damage an injector and with the gov taking out almost all of the sulfur the water now has more chance of collecting in a tank from condensation

Not just for the Duramax. Any modern diesel engine.
I run Stanodyne fuel aditive in my Cummins because out of the pump, most fuel is substandard.

I had a 15 Ram with the 3.0 ecodiesel. I think it was made by VM? They got caught up.in the Volkswagen diesel scandal ecause Bosch did the programming for both motors. After the epa mandated Approved Emissions Modification flash the truck had less power and fuel mileage dropped despite Rams and the epas insistence the AEM would not effect that. After the 2nd or 3rd recall without a solution or parts I ended up trading it it. Prior to the AEM I felt it was a decent motor. I sometimes kick myself because I liked that 15 Ram Longhorn better than the 19 Ram Limited I traded it for.

I'm guessing the gm AFM system is the same as the Hemis MDS cylinder deactivation system. I haven't had any issues with that or the 5.7 Hemis. I'm on my fourth one since 08(trade them in, not blow them up)

Now if we can get rid of the damn stop/start garbage. I managed to stall out an automatic last week because of that garbage.

GM 6.2 vortec does have DFM
If it's a gas engine from GM odds are it has AFM/DFM

I bought a 2500 Ram Cummins

To my knowledge, No 3/4 ton or 1 ton gasoline V8 in any brand has any type of fuel / valve train management on them.
HD pickups aren't under the same EPA MPG rules as the 1/2 ton truck segment is.

Lots of information out there saying they do..starting in 2014 the 6.0 and 6.2 did have AFM

Guys on forum have been discussing this and finding out they have it in their trucks

Some guys are also saying the AFM parts are in the engines but in some models the AFM software isn't present to activate it

WATER CAN CAUSE OTS OF DAMAGE IN MODERN DISELENGINES!

 

[Sam7sf]

Correct, the reliable 6.0 had it. Still a good engine.

I know Ford and Ram 2500 / 3500 gasoline engines don't. I also have a friend that is a GM mechanic at a local dealership, he has told me that Chevy / GMC 2500 / 3500 gasoline engines don't either.
My 2012 Ram 2500 Power Wagon with the 5.7 Hemi doesn't have it, neither does my friends 2016 Ram 2500 with the 6.4 Hemi.
GM lost my business when they started putting IFS on 4x4 trucks.

I really hate acronyms. I had to googlel IFS.
BTW. GM lost me in the 70s & 80s

Since the 80s? What's the problem?

All kidding aside, it's probably decent for a anything lighter than a 3/4 ton but I don't like it for heavy duty trucks.

HP tuners, reprogram the whole computer to deactivate AFM; change camshaft to non-afm and put non-afm lifters you’re good to go
