Attention! If a large amount of metal chips and other wear products are found in the engine oil during engine repair, this may indicate damage to the connecting rod or main bearings of the crankshaft. To avoid subsequent damage after repair work, it is necessary:
- thoroughly clean the oil channels;
- replace the oil filter;
- replace piston cooling jets (if they are installed);
- replace oil cooler.
