The invention relates to internal combustion engines. The method comprises installing an oil filter with a main filter element and a filter element for a pressure relief valve, then removing said oil filter after use, opening the filter and analyzing the filtered-out products resulting from wear in respect of the qualitative and quantitative composition thereof and to ascertain the engine parts to which said products belong. The invention makes it possible to determine, during operation, the degree of wear of the parts and to increase the ecological and technical safety of the method. |
