Abstract
A noise reducing oil pan assembly for a motor vehicle engine, adapted for attachment to the engine block underside, includes outer and inner nested pan units supported in spaced relation defining an oil chamber between the units. An inflow gap between the upper opposed edge portions of the units upstanding walls is positioned subjacent the outflow of engine block return oil passages. With the engine running, the return oil flow fills the chamber and thereafter the overflow is received by the inner unit reservoir for re-circulation to the engine. The chamber oil provides a barrier that dampens engine noise radiating from the oil pan assembly.
