That job is handled by the oil line, that carries oil up from the sump and into a drip hole in the top of the valve cover to lubricate the entire valvetrain. In theory there is always oil flowing into that pipe, and the excess pressure in the cases would only increase oil pressure, not flood that line with gas. In theory...Ha.
