Milodon billet aluminum oil pump covers feature a one-piece design that requires no gaskets or O-rings for installation. They are CNC-machined from billet 6061 aircraft aluminum and then anodized for protection. These covers are available in two styles--one for Hemi-type motor mounts and one for Wedge-type motor mounts. The Milodon billet aluminum oil pump covers are designed for use with external oil pickup line systems.
