The paper deals with diagnostic issues concerning endoscopic examinations of working spaces within marine diesel engines. In the beginning, endoscopy apparatus being on laboratory equipment of the Department of Ship Power Plants of Gdansk University of Technology has been characterized. The endoscopy considerations have been focused on theoretical bases of a digital image processing and especially - on the "Shadow" measurement method. Second part of the paper is devoted to operation damages of medium- and high speed engines that have been physically analyzed in many aspects of origin as well as places and character of their occurrence. There have been also considered possibilities of direct and indirect identification of the well known and recognizable operational unserviceable states of the elements of a piston's constructional system by means of endoscopic methods. The results of the author's own research as well as the accessible results of diagnostic research of the self ignition engines applied in automotive and railway transport have explained and proved the most probable reasons for the piston failures' occurrence.
