What happens when you throw a piston rod?
What happens when you throw a piston rod?
A thrown rod leads to an engine stopped cold in its tracks. A thrown rod pierces the engine block or causes the piston valve and cylinder unit to jam. In either instance, the event is a costly engine rebuild or replacement. Proper oil level or lubrication prevents friction and engine overheating.
What causes a connecting rod to break on a crankshaft?
The connecting rod connects the pistons to the crankshaft. It converts the linear motion of the pistons to the rotary motion of the crankshaft. On every stroke, the connecting rod is stretched and compressed. This pressure, plus other factors, can cause the connecting rod to break.
What happens when a connecting rod snaps on an engine?
If this pin snaps the connecting rod is no longer connected to the engine. For some engines this results in catastrophic engine failure–the connecting rod goes through the engine block or the crankshaft is bent–but for some engines it just causes a dramatic loss of power. If the engine is stopped immediately after…
What causes a connecting rod to go bad?
Fatigue Fatigue is the main cause of broken connecting rods–especially in older engines. The pin that connects the connecting rod to the piston (called the piston pin, wrist pin or gudgeon pin) gets a lot of wear. Over revving is the main cause of connecting rod failures in new and high performance engines.

What causes the connecting rod to go through the engine block?
This pressure, plus other factors, can cause the connecting rod to break. The broken rod can go through the engine block completely, ruining the engine–a condition known as “throwing a rod.” Fatigue is the main cause of broken connecting rods–especially in older engines.
