Quote HistoryOriginally Posted By staringback05: Like another said. 5.3 is a great motor....and then the government got involved If you find one in good condition...just tune out the active fuel management The oil consumption issues weren't all AFM related. But GM was able to decertify those class actions as well. |

Quote HistoryOriginally Posted By SNORCdriver: I still like GM trucks over the others but had to totally abandon 1/2 tons due to the 5.3 & the AFM BS. My 2024 silverado 3/4 tn 6.6 gasser still has a key (no stop start), no AFM and, as an added bonus, it's amazingly easy to disconnect the external antenna connection to the on-star & ECM modules This is where I'm at. Just bought a 2024 2500HD mainly to avoid the fuel efficacy crap on the 1/2 tons. Between the lifter issues and the lethargic transmission programming, I swore I'd never buy another one. I don't give a crap about the gas mileage. The 6.6 gasser is a great motor. |

Will the diablo tuner still work with these models?

Update: both banks failed. No codes but when took it apart three lifters were fucked up. Replaced both banks.
Dealer said they’ve never seen it happen twice which I’d say is a lie since they said if the cam was damaged engines were one month back order. Ordered the new Range DFM disabler. |

Quote HistoryOriginally Posted By staringback05: That fixes alot. The percentage of failures falls off once you turn it off. I do agree the lifters are a problem, but I can find several items on Ford and dodge engines that have significant failure rates Quote HistoryOriginally Posted By staringback05: Originally Posted By Bloviator: That only fixes part of the problem. You need to strip the engine down to a short block, change the cam and lifters to completely fix it. That fixes alot. The percentage of failures falls off once you turn it off. I do agree the lifters are a problem, but I can find several items on Ford and dodge engines that have significant failure rates It fixes nothing. The Hardware is still there waiting to break. Why make excuses? |

I was able to put about 220k miles on my 2007 with AFM but at about 150k I bought a dongle to disable AFM as I could feel it in 4 cyl mode and didn't like it. I used Mobil-1 exclusively so that may have helped it survive. Honestly, motor mounts were the biggest issue in the engine compartment.

Quote HistoryOriginally Posted By forager: Anything with Active fuel management is prone to the issue... not sure about the newer stuff.. but 07 and up... suspect Thankfully I have a 2005 6.0 that's going strong at 198k, all original drivetrain. GM has screwed the pooch. My elderly dad's 2021 Chev1500 5.3 with just 21k shit the bed in middle of nowhere stranding him and his SO a couple weeks ago in NM. Possibly a blown head gasket...from a car that gets driven like once a week to church and grocery store FFS. I've building Buick, Pontiac, and Chev engines and driving GM products since the 80's and will now not touch a newer GM product. |
