Oil sepator, lean codes and hesitation

I have a question about a 2006 BMW 325i .
The car has lean codes and hesitation under heavy acceleration. I changed fuel pump because the fuel pressure was low and changed the fuel pressure regulator. I changed all the vacuum hoses and oil sepator but still i have the hesitation and lean codes for bank 1 and 2.
When I was changing the vacuum hoses, i noticed alot of oil in the intake manifold, before that there was smoke coming from the tail pipe.
I changed vacuum hoses the replaced the oil sepator that I bought from bmw dealership. I noticed about two weeks ago the oil had reduced again after all that service. So I watched one of your videos and decided the replace the oil sepator relay. It Worked for like two weeks now oil is back the intake manifold. What could be the problem?
