More than 90% of the oil leakage problems are caused by the long-term heating and cooling of the rubber seal ring, which causes the seal ring to lose a lot of plasticizers and softeners, and the problem of corrosion, aging and hardening occurs. At first, it was oil leakage, and slowly began to drip. After a long time, the sealing ring broke. In the past, the oil leakage was solved by removing the engine oil seal. Now with the development of science and technology, it is not dismantled and repaired. Way, it can also solve the problem of oil leakage.
