X5 CYCLONE VALVE VENT PIPE GETTING PLUGED WITH CAPUCCINO LIKE FROTH ,IF YOUR OIL CAP LOOKS LIKE THIS DO NOT DRIVE UNTIL FIXED !!!

Short distance driving and frequent starts will get your oil vapour worked up to a froth of capuccino like gue and will freeze soled plugged if temperature drops bellow freezing . As a result the return line will get plugged and the oil will back up to the intake manifold,this car came in with only two liters of oil remaining out of the eight liters in it's sump and was making a horible noise due to valvetrain oil starvation she suvived the ordeal but just by luck only.
