What Causes a Car to Throw a Rod? 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.


To put it simply, a blown engine is an engine that has suffered catastrophic internal mechanical damage. Your engine doesn’t actually blow up, though some immediate symptoms of a blown engine can be smoke, steam and, rarely, fire. Sometimes a piston rod will punch through the wall of an engine block, necessitating an engine replacement.
