If the failure of turbine end oil seal, the exhaust gas through the sealing ring into the engine lubrication system, time will make the oil premature failure.
In addition, the engine running at a low speed, the oil will through the sealing ring into the exhaust pipe, exhaust emissions from the exhaust pipe, exhaust pipe smoking phenomenon caused by;
if the failure of compressor end seal, inside the intensifier the oil will enter the compressor casing, with intake are sucked into the cylinder combustion, resulting in excessive consumption of oil, "burn oil" phenomenon, serious when can cause the carbon deposit increase.
