ABSTRACT:
An internal combustion engine includes an engine block, an oil pan, a sound insulating capsule and a sealing gasket connecting the oil pan to an underside of the engine block. The sealing gasket has folds for permitting a relative displacement between the engine block and the oil pan during operation of the engine. The sealing gasket is supported on a lower portion of the capsule as a component thereof, while the capsule is supported externally of the engine. A closure plate is sealingly secured to the engine block for covering an underside of the engine block. The plate has an oil return opening whose dimensions are small relative to length and width dimensions of the closure plate and the oil pan. The closure plate and the oil pan carry nipples which are in alignment with one another and to which the sealing gasket is secured.
