Cracked Open: What Really Ends the Life of Ford's Gen 3 Coyote V8
This Coyote V8 is locked up at over 100,000 miles, but how bad it is inside? From Muscle Cars to Trucks: The Flexible Modular Coyote V8 Ford introduced its Coyote V8 engine as an evolution of its modular V8 platform, marking the Blue Oval's return to high-performance V8s, particularly in the Mustang GT. However, this engine isn't just exclusive to the long-running muscle car nameplate – several models also made use of this versatile engine, some even outside Ford's stables. The Ford F-150 is one such model that benefits from the Coyote V8, particularly its third iteration, introduced in 2018. This generation of the Coyote received both port and direct injection, along with PTWA liners and increased bore. It even saw the birth of the 'Predator,' a 760-hp supercharged variant used in the mighty Raptor R. Dead at Over 100,000 Miles The Coyote V8 has established itself as a reliable performance-driven mill, but it's also known to be reliable, suffering only a handful of issues associated with its name. Some can reach hundreds of thousands of miles – like this example in the spotlight by YouTube engine coroner, I Do Cars. In this teardown video, we get to see a third-generation Coyote V8 from a 2018 Ford F-150, which is presumed to have reached over 100,000 miles. The engine is apparently all locked up, but further inspection revealed what killed the Coyote and what made it such a special specimen of Ford engineering. Looking Good From the Get-Go While I Do Cars was under the impression that the V8 in question was all banged up, initial inspection showed that it wasn't too bad. It rotated manually with a few internal clicks. The spark plugs appeared to be overdue, and while the intake ports were dirty, the valves were clean enough to suggest port/direct injection was helping. Further examination of the top portion showed promising revelations, with clean sections after removing the valve covers. There were no metal glitter, damaged cam lobes, or broken valvetrain parts. Interestingly, a timing chain slap was discovered as the source of the clicks, due to the unloaded oil pressure-dependent tensioners. Minimal Wear, With Only One Major Problem However, the cylinder heads showed heavy carbon and oil deposits, suggesting the engine was burning oil. One cylinder showed odd residue or discoloration, while the pistons came with a heavy carbon buildup in ring lands, suggesting oil control ring failure. Some oil rings were seized, others barely protruded, confirming oil consumption problems. Overall, the Coyote V8 engine teardown showed minimal and typical wear after over 100,000 miles (apart from the plastic oil pan), with I Do Cars claiming it is a candidate for a rebuild. It wasn't flawless, but its failure was only from burning too much oil, which led to catalytic converter damage – the only persistent problem associated with Coyote V8s, beyond issues with its 10-speed transmission.

Engine Teardown Reveals Internal Failures Behind GM's L87 6.2L V8 Recall
Engine Teardown Reveals Internal Failures Behind GM's L87 6.2L V8 Recall originally appeared on Autoblog. General Motors began 2025 facing a major issue: the National Highway Traffic Safety Administration (NHTSA) launched a formal investigation into the company's widely used 6.2-liter L87 V8 engine. The probe affects 877,710 full-size trucks and SUVs, after multiple reports of engine failures were filed with the agency. The investigation has since led to a large-scale recall and a stop-sale order. In some cases, these engine failures occurred while driving down the highway or just a few miles into vehicle use. Needless to say, they pose serious safety risks. View the 3 images of this gallery on the original article The list of affected vehicles includes the not-rookies-to-recall Chevrolet Silverado 1500, Tahoe, and Suburban; the Cadillac Escalade and Escalade ESV; and the GMC Yukon, Yukon XL, and Sierra 1500, model years 2021 to 2024, all powered by the small-block V8 engine. The American automaker hasn't pinpointed the exact issue with the problematic power plant, only saying that the connecting rod and/or crankshaft components have unspecified manufacturing defects. But what happens inside the L87 V8 engine when it fails? Internet mechanic I Do Cars got its hands on one for an engine teardown, providing a more intimate look at the internals of one of GM's V8 mill that faced a catastrophic failure. The engine in question is said to have been recalled (from a 2022 GMC Yukon Denali), although details of how he got it weren't disclosed. The teardown starts optimistically: the engine can be cranked by hand, indicating no fully seized components. However, the first sign of trouble appears on the pushrods, which exhibit abnormal wear. The lifters, though none have completely collapsed, show signs of debris exposure, with one in particularly poor condition. View the 2 images of this gallery on the original article Removing the oil pan reveals more – a lot more. The internal oil has turned carbon-black, indicating severe overheating and oil breakdown. All eight connecting rods are completely shot, showing extensive damage. The camshaft lobe is also missing a chunk, while the block's front shows scoring, suggesting the crankshaft struck the block. The teardown reveals significant and unusual damage for a relatively young and modern engine, though it aligns with GM's claim that the problem lies with the connecting rods and crankshafts. It's also likely that this engine failed gradually, unlike other reported cases of instant engine failure. As the presenter notes, the owner likely ignored early signs of engine trouble, leading to more catastrophic damage. As part of the recall, GM has already provided a solution to the issue. Affected engines that haven't failed yet will have their oil replaced with thicker 0W-40 oil (replacing the former 0W-20), offering increased protection at operating temperatures. They will also get a new oil filter and oil fill cap that reflects the change. Engines that were shot will be replaced. However, not everyone's happy with GM's band-aid solution to this widespread problem. A lawsuit claims that replacing the engine's oil with higher viscosity would decrease fuel economy. The lawsuit claims that "owners are presented with two bad options: do nothing and risk catastrophic engine failure or get the recall and pay hundreds of dollars more for gasoline."

Someone Installed a Head Gasket Upside Down on This Small Block V-8
GM's 6.2-liter L87 small-block V-8 is subject to a huge recall over bad crankshafts and/or connecting rods in engines built between 2021 and 2024. This earlier L87 V-8, from a 2019 GMC Sierra Denali, is destroyed for an entirely different reason—likely human error. The always-entertaining I Do Cars on YouTube tears down an L87 in this video. This example has less than 50,000 miles, and the car it came from had a good service history. But it doesn't take much unbolting to reveal an engine with catastrophic damage. And it appears the problem isn't GM's fault. For whatever reason, the truck had a lot of work done to at the dealer it before customer delivery, and as a commenter who claims to be a GM mechanic points out, the driver's side head gasket was installed upside down. It's unclear how long the engine ran with its upside-down head gasket, but run it did, until it inevitably overheated. The commenter says that the improperly installed gasket blocks the coolant passages to the head, which severely limits cooling and will result in failure. Which is why the driver's-side head looks so terrible, especially compared to the passenger-side head, and even with frequent oil changes. There's all sorts of carnage deeper in the engine. Two of the connecting rods got extremely hot, and likely locked up the engine, causing the destruction we see here. What's funny is that there's even the word "FRONT" stamped into the head gasket to prevent exactly this sort of thing from happening. But, you truly can't make everything foolproof.
