Some early Captivas fitted with the diesel engine may have experienced a condition whereby the camshaft rocker arm bearing could fail. In some instances this rocker arm failure was known to result in damage to the camshaft(s). A revised camshaft rocker arm assembly was released into vehicle/engine production to address this problem. These revised parts were also made available to service to replace any failed parts in the field. The service fix advice if presented with a 'Rocker arm failure', is to replace all the rocker arms with the revised parts.
