Abstract
A baffle for use in an interior of a cam cover and a method of making the baffle are disclosed. The baffle includes a structural layer, which is made of metal, and an isolation layer that is made of a resilient foam. The isolation layer is disposed on a surface of the structural layer in a pattern that leaves uncovered a portion of the surface of the structural layer. When the baffle is installed in the cam cover, the isolation layer provides an interface between the structural layer and the cam cover, which isolates the baffle from vibrations in the cam cover. Since the isolation layer is applied only where it is needed, the disclosed baffle and process use less material.
