Connecting rod bushing Nissan 1963-1980 SD20, SD33 ACL The connecting rod head bushing is a piece of metal tube pressed into the connecting rod head, adjacent to the piston pin. It works in extreme conditions as a sliding bearing. The use of oil with the wrong viscosity, oil deficiency, low pressure in the lubrication system, too much load on a cold engine, neglect of oil change intervals or incorrect mounting of the connecting rod cause excessive load on the bushings, their faster wear. a knocking noise at idle indicates that the bushing must be replaced immediately. Delaying replacement can lead to the element seizing up, causing damage to the entire connecting rod.
