I've torn apart 27 GM engines in my garage over the last 4 years. Nearly all of them failed the exact same way. And if you drive a GM truck or SUV, you probably have no idea this could happen to you... I need to talk about this because it's getting worse, not better, and nobody with a platform is saying a damn word. I'm not a shop. I'm a millwright by trade. I work at a paper mill Monday through Friday. But I've been wrenching on trucks since I was 14 years old and I do side work out of my garage on nights and weekends. Word of mouth stuff. Guys at work. Neighbors. Friends of friends. I don't advertise. I don't need to. Because right now, about half the work that comes through my garage is the same exact job. GM lifter failure. 5.3s. 6.2s. Silverados. Sierras. Tahoes. Yukons. Suburbans. I've even done an Escalade. 2007s all the way up to 2022s. I pulled one apart last month that had 41,000 miles on it. Truck was 3 years old. Guy still owed $42,000 on it. Lifter collapsed on cylinder 7, chewed the cam lobe completely flat, and sent metal through the oil system. I had to flush the entire motor twice before I could put it back together. His face when I told him the estimate. I'll never forget it. He didn't say anything. He just walked out to his truck, sat in the driver's seat of a truck that wouldn't start, and put his head on the steering wheel. His wife was 7 months pregnant. They'd just bought a house. And now he was looking at a $6,400 repair on a truck the bank still owned. I see this every month. Every single month. And it's always the guys who did everything right. That's what kills me. Synthetic oil. 5,000 mile intervals. Dealer records. These aren't guys beating on their trucks at the drag strip. These are dads. Working guys. Guys who need their truck to get to work and feed their families. And they all have the same thing in common. None of them knew about AFM. Active Fuel Management. That's what GM calls it. It's a system they started putting in their engines in 2007 to meet government fuel economy standards. It shuts down half your cylinders while you cruise. Your V8 turns into a V4 at every stoplight, every highway merge, every school zone. The lifters that make it work have a tiny locking pin that cycles on and off hundreds of times per drive. Lock. Unlock. Lock. Unlock. For years. Until one day the pin fatigues and the lifter collapses. When it collapses, it stops spinning and grinds through your camshaft like a file on aluminum. If you catch it early, maybe you're looking at $3,000 to $5,000. New lifters, new cam, new gaskets, 15 hours of labor. If you don't catch it early, the metal shavings go through your oil system. Into your bearings. Into your oil pump. Into everything. Now you're looking at $8,000 to $12,000. Or a new engine entirely. And here's what nobody ever explains to these guys. That little shudder your truck does when you're cruising at 40 or 50. That tiny vibration you barely notice anymore because you've gotten so used to it. That's AFM. That's the system cycling. Right now. In your engine. Every time you drive. And every time it cycles, it's one step closer to the day you hear the tick. I started keeping a list on a notepad in my garage of every AFM engine I tear apart. Date, truck, mileage, damage. 27 engines in 4 years. The lowest mileage was 19,000. A 2021 Trail Boss. Kid had it 5 months. The highest was 168,000. A 2008 Silverado. Guy had been lucky for 16 years. His luck ran out on a random Wednesday. There is no pattern. There is no safe mileage. There is no magic oil that prevents it. The lifter fails when the lifter fails. Period. About 3 years ago I started telling every single person who brings a GM truck into my garage about a module that disables AFM. It's called FullFire. It plugs into the OBD2 port under the dash. Takes 2 seconds. It tells the engine computer to keep all cylinders firing all the time. No more AFM. No more cycling. No more hammering those lifters back and forth every time you drive to work. Doesn't reprogram anything. Doesn't touch the ECU. You can pull it out before a dealer visit and there's zero evidence it was ever there. I've put them on my own trucks. Both of them. My 2014 Sierra that has 147,000 miles. And my 2019 Silverado that has 68,000. Zero lifter issues on either one. Every truck I rebuild, I install one before it leaves my garage. I tell the owner what it does, I tell them why, and I tell them the risks of removing it. Not a single one has come back. But every month, a new truck shows up. A new guy standing in my garage with that same look on his face. A new engine that ate itself because of a system designed to save a mile per gallon. I don't know why GM hasn't changed this. I don't know why dealers don't warn people. I don't know why this isn't talked about on every truck forum and every car lot in America. But I know this. If you drive a GM truck or SUV from 2007 or newer with a V6 or V8, you have AFM. You have those lifters. And the clock is ticking on every single one of them. I'm not trying to scare anyone. I'm trying to tell you what I've seen with my own eyes dozens of times in 4 years. A simple plug-in device would have saved every single one of them. Please share this. I just want people to know before they end up in a garage staring at a camshaft that looks like it went through a wood chipper. EDIT: Getting flooded with messages. The module is called FullFire. Here's where to get it: 👉 https://shopmillton.com/pages/fullfire I've installed dozens of them and never seen one come back. Please just get one and stop the cycling before it destroys your engine.
