Rod failures can also occur as a result of metal fatigue.A small surface blemish,nick,scratch or imperfection on a rod will concentrate stress.Eventually,this can lead to microcracks in the metal and ultimately a fracture that causes the rod to break.Most performance rods have a machined smooth surface to reduce the risk of stress fractures.Preventing Connecting Rod Failures - Engine Builder MagazineRod failures can also occur as a result of metal fatigue.A small surface blemish,nick,scratch or imperfection on a rod will concentrate stress.Eventually,this can lead to microcracks in the metal and ultimately a fracture that causes the rod to break.Most performance rods have a machined smooth surface to reduce the risk of stress fractures.
