Oil Sump Changeover Valves

The oil supply system of the S62B50 engine is specifically designed for the M5, due to its ability for high speed cornering that could cause the engine oil to be forced (and trapped) into the outer edge of the cylinder head and the rear area of the oil sump. To prevent oil starvation from occurring during these driving situations, 2 additional scavenging oil pumps are installed within the main oil pump housing. The main oil pump's function supplies the engine with the required volume of oil for all of its lubrication needs. The 2 additional pumps only supply oil sump with scavenged oil. Each additional oil pump incorporates a solenoid changeover valve that is connected to 2 scavenging tubes that pickup from the rear section of the oil pan and the outer edge of the cylinder head. The scavenging tubes in oil pan crossover so right side pump draws from rear left side of pan and left pump from right side of pan. MS S52 control module receives "G" force signal from DSC control module over CAN line.
