ABSTRACT:
A plastic oil pan for internal-combustion engines is disclosed which includes an oil drain plug screwed into a threaded insert. This oil drain plug is braced with respect to the threaded insert. In order to avoid an undesirable discharge of oil when the oil drain plug is fixed, a radial seal is operative between the oil drain plug and a recess in a local thickening of the oil pan.
