Engineers Say They Finally Found What’s Causing Modern Engine Failures

For years, engineers couldn't explain it. Across the country, near-new trucks were dying without warning — V8s seizing on the highway, eighty-thousand-dollar SUVs reduced to scrap overnight — and every automaker blamed something different. Every one of them was wrong. Then teams at rival companies, all quietly hunting the same killer inside their own engines, finally cornered it. And what they pulled into the light wasn't a broken design, or a software glitch, or a bad batch of fuel. It was so small you could lose it in the palm of your hand — and it just rewrote everything we thought we knew about the modern engine.
