2. The engine will start to suffer from sluggish acceleration and vibration.

 

In practice, the valve oil seal breakage is not common, more corrosion aging caused by burning oil. Once the car cold blue smoke, generally speaking, are valve oil seal problems. The traditional method is to solve the problem by dismantling and repairing the valve oil seal, but dismantling and repairing is time-consuming, laborious and expensive, and sometimes we will also cause more other problems because of the quality of the parts, technology and assembly production process and other uncertain influencing factors.
