The engine was not overfilled with oil.

I have done a leak down test, with these results:
1 - 2%
6 - 3%
2 - 3%
4 - 2%
3 - 2%
5 - 3%
These results was done with 100psi.

Do some of you have any ideas of what the problem can be?

Thanks

It is possible your turbo is getting closer to needing a rebuild. As the journal bearings go the seal rings go and you get exhaust gas back into the crankcase.
