The owner reported that about 1 liter of oil was consumed after driving for 1,000 kilometers, and the vehicle traveled for 90,000 kilometers, but there were no other abnormal conditions. We gave a maintenance plan. After inspection, we found that there was no obvious abnormality in the air pressure change in the crankcase when the engine was running.
The problems of cross-over and crankcase ventilation could be temporarily eliminated, and it was decided to replace the valve oil seal first. Due to the narrow space of the vehicle, the engine was removed and replaced. Some other faults were discovered during the disassembly process.
