S-CLASS Masterpiece Gone Wrong: Mercedes M176 FAILED Engine Teardown!

Here is a complete, top-to-bottom engine teardown of a failed Mercedes-Benz M176 4.0L Twin-Turbo V8 engine pulled from a 2018 Mercedes-Benz S560 with only 58,000km on it! The owner was hit with a staggering $80,000 replacement bill after this luxury yacht's engine suddenly started knocking. In this video, I'll dig deep into the block and connecting rods to find out exactly what went wrong, and what's inside this M176 engine and how it works. Was it a catastrophic oiling issue, a botched oil change, or a fatal flaw in the cylinder walls? Watch as I'll strip down this incredibly complex yet impressively machined, manufactured and put together German powerhouse, analyze the carnage, and reveal the exact component that turned this beautiful high-tech V8 into scrap metal. The Mercedes M176 is also related to the M177 series of engines used in the AMG versions of their V8 twin turbo vehicles, with similar component layout. Service is often complex with very limited room in the engine bay to work, requiring the removal of the engine to access wear items.
