A cylinder head cover, a system, and a method are disclosed for sealing a cylinder head and isolating cylinder head vibrations from a cylinder head cover body. An example cylinder head cover may include a bottom carrier having a first end configured to be disposed in sealing engagement with a cylinder head. The bottom carrier may also have a second end. A cover body may be configured to provide a covering surface, and may have a side wall extending toward the cylinder head. A resilient joining element may connect the bottom carrier second end to an edge of the cover body side wall in sealing engagement. An example method may include positioning a substantially rigid bottom carrier on the cylinder head, the bottom carrier including a sealing member configured for sealing engagement with the cylinder head; sealingly connecting a membranoid elastomeric joining element to the bottom carrier; connecting the cylinder head body to the joining element; and forming a substantially continuous sealing membrane with a combination of the bottom carrier the joining element and the cylinder head body.
