An internal combustion engine is provided having an engine block operably engaged with at least one cylinder head for defining an oil conditioning system therein. The oil conditioning system includes a series of oil and coolant flow channels running through the engine block, an oil trough formed within a central portion of the engine block and in fluid communication with an oil pan for collecting oil therein. Oil flows from the oil pan and into the cylinder head for lubricating components therein. The oil drains from the cylinder head into the oil trough which is in heat exchange relationship with various coolant flow channels for heating or cooling the oil flowing through the oil trough. The oil then drains from the oil trough back to the oil pan.
