Abstract
An engine block with an oil path switching arrangement is proposed. The engine block includes an oil sump, an oil pump, a clean oil riser and a switching valve. The switching valve has in each case connections for the oil sump, the oil pump and the clean oil riser. The switching valve is switchable to open and close the connections, including a first position in which a connection between the clean oil riser and the oil sump is established, thereby avoiding discharge of oil in the clean oil riser through an oil filter receptacle during an oil change.
