Abstract
An engine assembly for a vehicle includes an engine crankshaft protruding from a front end of a cylinder block of the engine. A front cover is secured to the front end of the engine. A pump is positioned within the front cover and operatively connected with said engine crankshaft. A fluid passage is formed by the front cover for receiving pumped fluid from the pump and directing the fluid into the cylinder block. The fluid passage has an exit port with a curved portion of the passage positioned closely adjacent the exit port. A plastic insert is positioned within the curved portion and within the exit port. The plastic insert has a plurality of curved fluid flow vanes to direct flowing fluid through the curved portion in a manner to improve laminarity of flow in the curved portion and in the exit port to reduce fluid flow losses.
