Abstract

Internal combustion engines for motor vehicles are lubricated with oil from an oil sump which is screwed to the bottom of the engine block. For reducing transport of vibrations from the engine to the oil sump each fastening screw is provides with a spring around the screw and which act as an axial damper between the screw and the sump. According to the present invention, transport of vibrations from the engine block to the oils sump is further dampened by arranging a rubber tube around the fastening screws thereby avoiding the screws to be in radial contact with the respective springs.
