How to solve the problem of oil leakage found in the new Focus engine?

More than 90% oil leakage is caused by corrosion and aging of oil seals. Especially cars that are more than three years old. Because the rubber seal will lose plasticizer under the influence of long-term alternating temperature change, the consequence is that the seal will shrink, harden, lose elasticity, and even break seriously (this degree is far from being achieved, and oil leakage will be found during maintenance), and the oil leakage problem is inevitable.

This problem is not recommended to be dismantled and repaired, ranging from hundreds to thousands or even tens of thousands at a time. But it may not solve the problem and hurt the car. It is suggested that the majority of car owners use the method of "no disassembly and no repair to solve the oil leakage of the car" instead of disassembling and repairing to solve the car problem.
