WARNING: This page is about a different car, the 2020 Jaguar XF and 2019 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
Gas and oil vapor from the engine enter the part load breather. The vapor passes over the engine vent oil separator. The oil passes back into the engine. The vapor is drawn into the intake of the supercharger.
