Last weekend I did a test with the old installed filter. It was removed and cleaned with a specific gel. It was totally covered by oil!! The enclosure and the rubber gasket were was also clean. Then, after dry all parts I reinstall all back. I realize some strange noise when turbo starts to run, like a leakage pressure. I removed again everything and I noticed a problem in the gasket. Because I hadn't new gaskets, I decided to put a special insulation product, together with the old gasket, like a high temperatures red silicone that normally is used in this kind of works. Know it it OK and the behavior of the engine is more silent and has a better response. I noticed that the breather filter case has only four screws that if my opinion in not sufficient when new gaskets are not available.
I will run some kilometers and I will see the results. After that I'm thinking to change for the BMW part.
Just one question, the BMW breather filter has a filter itself or it some different thing? How can it breathe and separate the oil?
Thanks
