guys, if you could just follow the link... Some of those items are Genuine and some not.
also, I am suspecting that OFH gasket gives up few drops of oil as well and gasket for that only available from company called Meistersatz trough FCP, do you think I should just go to nearest BMW stealership and pick up genuine one or order it from other supplier? In link below, there is a air hissing sound that somewhat resembles what I hear from my engine, may be not exactly to that extend but close (I did smoke test OK and DISA is brand new oem) so I ordered PCV Kit to do with OFH at once, what do you think?
