How did C4L burn engine oil after changing the timing belt?

This is a common problem of this car, not only C4L and Peugeot 408, but also because of the burning oil when the timing belt is replaced after hair loss. At present, the manufacturer only solves the problem of timing belt shedding, and there is no unified solution to other problems after replacing the timing belt. The evaluation of these two cars on the car quality network is extremely low, and the main reason for the large number of complaints is also the problem of burning engine oil. Generally speaking, there are many problems with Dongxue's awarded the East Standard, but many of them are caused by unqualified parts.
