摘要

An engine front cover assembly includes a plastic engine cover. A metal insert is secured within the plastic engine cover and defines a bore configured to receive a rotating engine component. A seal is located in a seal seat defined within the bore of the metal insert and configured to sealingly engage the rotating engine component. The metal insert is overmolded within the plastic engine cover and serves as a datum point to properly locate the seal relative to the rotating engine component.
