An oil pan baffle is secured by a securing device on the oil pan. The securing device has an oil pan gasket with a gasket body matched to a sealing contour of an oil pan relative to a crankcase and securing elements that are connected to the gasket body and project inwardly away from an inner perimeter of the gasket body. The securing elements act on contact surfaces of the oil pan baffle, with which contact surfaces the oil pan baffle is positioned in receptacles of the oil pan, and exert pressure effecting secure fixation of the oil pan baffle on the oil pan when the oil pan gasket is compressed by mounting the oil pan on the crankcase.
