Chugs coolant, misfires hot, and smells like scorched oil after shutdown. That is the 2.7L TurboMax under stress. GM built it to pull like a diesel and sip like a four. It features a strong block, forged internals, and smart cooling. But in the real world, cracks form, literally. Some 2023 castings fail under pressure. … Read more
Shift to Park. Walk away. The truck moves anyway. Thousands of rebuilt 10R80 transmissions left the factory missing a critical bearing. Others slam into gear, slip at highway speeds, or lurch without warning; thanks to a mix of hardware flaws and software band-aids that mask deeper pressure loss. This guide breaks down how the design … Read more
Cold-start tick. You hear it once, and your eyes go straight to the cluster. On Kia’s 2.4L Theta II, that tick turned into knock, stall, and in too many cases, engine fire. The failures weren’t flukes. They were baked into the build. Crankshaft machining left metal shavings behind. Those bits tore up the rod bearings … Read more
Hit 70, feel the rumble, then catch a downshift that makes no sense. That’s when you stop trusting GM’s 10-speed, not because it screams, but because it acts like it’s guessing. The story repeats itself. Light throttle at highway speeds triggers a vibration like you’re hitting rumble strips. Cold starts throw a 1–2 shift that … Read more
It starts with a knock. Then the light flashes. Then the power’s gone. One minute your Hyundai or Kia runs fine. The next, it’s rattling, bogging, or shutting off mid-drive. And you’re left wondering, did the engine just die, or did Hyundai already know it would? This isn’t bad luck. The 2.4L Theta II has … Read more
Skip the diesel, buy the big gas Ford, and it still starts ticking at idle. You feel a stumble when pulling, hear chatter at red lights, or catch the 10-speed hunting for a gear on mild climbs. That’s where confidence fades and the 7.3’s reputation starts to slip. Most Godzillas hold up. The ones that … Read more
Buy a 5.3 thinking it’ll run quiet for 200,000 miles. Then the lifters start ticking, and the oil light won’t shut up. Online forums crank that worry into chaos, lumping three totally different engines into the same horror story. That’s how solid trucks get blamed for failures they don’t even carry. Break the 5.3 down … Read more
Step into the throttle with a trailer behind you, and the 6.6 Duramax should pull like it means it. When it bogs, runs hot, or flashes REDUCED POWER, you already know what’s coming; a real fix, real money, and no easy shortcut. Each generation brings its own set of habits. Early models chew through injectors … Read more
Skip diesel, grab the gas 6.6, and you expect fewer headaches. Then the oil starts disappearing. This engine’s built like a throwback, cast-iron block, no turbos, no DEF, no AFM. Just old-school displacement meant to haul without electronic second-guessing. That’s the appeal. But problems creep in. Oil drops fast under load. Hot starts drag. Some … Read more
The 8L90 doesn’t blow chunks. It jitters, hesitates, then smooths out like nothing happened. That’s what makes it hard to pin down. One day it feels like a tire’s out of round. Next day it bangs the 1–2 shift when cold. No codes, no warning lights; just a transmission that feels wrong in a different … Read more
