301 dense white smoke

Hello, there are 14 models 301 im in 110 thousand. It has been throwing very intense white smoke for about 1 month. First, they said turbo, a week later it happened again. Then the particle filter was full, said another master, we cleaned it. But it is still blowing smoke. It starts after 4 thousand cycles and there is excessive smoke for about 15 minutes. No oil, water reduction. The last three masters also said that I should not worry that this is from the Euro 5 engine. Do you think the problem is important? the Esesg 2017-12-01 12:17:22

First of all, welcome to us. There are a few topics in the forum that are either caused by injectors or valve tires.
