If the e39 OEM CCV is changed with a 39M5 cyclone separator (which has no diaphragm), and at the bottom we fit a check valve so as to avoid oil suction, would that not be a better solution? The M5 cyclonic separator has the 2 main lines going in/out and the bottom for the oil separation, pretty much like the OEM diaphragm CCV. But now, you eliminate the freezing of the diaphragm, or the rupture of it. Not sure if the vacuum is at the correct spec, but this will allow to keep the hoses where they were in a OEM built car, so you still have access to everything else pretty easy.
