What Causes A Rod To Go Through An Engine Block? A thrown rod is usually the result of metal fatigue, insufficient lubrication or over-revving of an engine. When gasoline combusts in a cylinder, it drives the piston head downward, pushing the connecting rod and turning the crankshaft. Throwing a rod is usually a catastrophic engine failure.
What does it mean when an engine throws a rod? The metal part that connects the piston to the crankshaft is called a “connecting rod.” RAY: When you “throw a rod,” it means that one of these rods has literally broken off. If the rod breaks while the piston is on its way up, the piston keeps going up until it jams itself permanently into the cylinder head.
Can you fix an engine with a thrown rod? A thrown rod means a portion of the rod is being thrown around inside the engine. As you run the engine, it will continue to cause more destruction. In almost every case, if you’ve thrown a rod, complete engine replacement (at a minimum, most likely a shortblock) is needed to fix your issues.
