The invention relates to a method for controlling the oil pressure of an oil pump () in a combustion engine (). The combustion engine () comprises a crankcase () and a separator () for separating oil present in a blow-by gas from the crankcase (). The method comprises the step () of providing oil pressure demand for a set of different engine operation conditions, the oil pressure demand defining the theoretical required oil pressure of the oil pump (); the step () of controlling the oil pressure of the oil pump () based on the oil pressure demand for at least one engine operation condition in the set of different engine operation conditions; the step () of driving the separator () using oil from the oil pump (), the oil being pressurized based on the oil pressure demand.

A device for cleaning a contaminated crankcase gas generated during operation of an internal combustion engine is provided. An internal combustion engine including such a device is also provided. The device permits for an increased flexibility as to constructing the cleaning device while maintaining or possibly improving cleaning of the contaminated crankcase gas.
