Why you NEVER Ignore Rod Knock

How does a car engine blow a massive hole in itself?! 🤯🔧
When mechanics joke about an engine "throwing a rod" or getting "custom block ventilation," this is exactly what they mean! Inside your engine block, the pistons are attached to the spinning crankshaft by thick steel connecting rods. If the engine runs low on oil, severely overheats, or is pushed way past its horsepower limit, the internal bearings can seize up.
When that happens at thousands of revolutions per minute, the intense kinetic energy instantly snaps the solid steel rod in half! The broken metal then acts like a missile, violently punching a massive hole straight through the side of the solid aluminum engine block! This is the ultimate catastrophic failure, and it guarantees you are buying a completely new engine!
