Abstract
A valley shield operable as a noise, fluid, and heat barrier is provided for use with an engine assembly having an engine block with two cylinder banks defining an interbank valley therebetween, and two cylinder heads secured thereto. The valley shield has a unitary body including a base with two laterally spaced side portions extending angularly outward therefrom. The body is configured to pressably fit into place proximate to the valley, between the two cylinder banks, and be secured therein by the cylinder heads. The base is oriented immediately adjacent to the interbank valley and is contoured to define an air pocket therebetween. Each lateral side portion includes a flange extending laterally therefrom to directly engage with the perimeter of the interbank valley, providing an acoustic seal therebetween. The base defines two longitudinally displaced trough portions each defining drain holes and configured to allow for gravitational evacuation of fluid therefrom.
