Due to the wide range of inclines Land Rover vehicles operate across, the geometry of the oil pan has been configured to guarantee oil pick-up across all operating angles. An oil scavenge system has been developed to guarantee excellent oil flow through the turbochargers on severe side-slopes. At extreme angles there is a risk the turbochargers may be below the oil level in the oil pan, restricting oil return flow.
To overcome this, the engine uses:
- The oil pump to supply oil to the turbocharger bearings from the main reservoir of the oil pan.
- A secondary reservoir in the oil pan, sealed off from the main reservoir, to receive oil from the turbocharger bearings.
- The vacuum and oil scavenge pump to assist the oil flow from the turbocharger bearings by scavenging oil from the secondary reservoir into the right camshaft cover.
For service, a drain plug and an oil extraction tube are installed to drain the main body of the oil pan.
