What are the symptoms of valve stem seal burning oil?
1 Answers
The symptoms of valve stem seal burning oil are: 1. The engine burns oil, and blue smoke comes out of the exhaust pipe; 2. Spark plug carbon deposits, resulting in reduced vehicle power; 3. The decrease in sealing performance leads to insufficient cylinder pressure in the engine, and the vehicle's power will also decrease; 4. The rate of oil burning accelerates, and in severe cases, the engine may lack cooling and lubrication, leading to cylinder explosion. The reasons for valve stem seal burning oil are: 1. Foreign objects or dust entering the pipeline during installation, causing seal damage; 2. Poor assembly; 3. Incorrect seal installation direction; 4. The oil seal and rotating shaft are not coaxial, resulting in eccentric wear.
