I've been reading about the OSV issues here on the site. I saw where several posters mentioned the idea but never read if anyone did indeed replace their oil separator valve hoses with silicone hoses. Mine have turned to putty/play dough just like everybody else, so I'm looking for an alternative to using rubber hoses again. Also, did BMW release an electrically heated OSV, never found a clear answer for that one, even after googling it?
