ABSTRACT:
A plastic gasket assembly of substantially increased thickness, compared to present day elastomeric or composition gaskets, for use in sealing an engine valve cover to a cylinder head thereof, the gasket including a portion incorporating an electrical conductor for creating an electrical bridge through the sealing area between the cylinder head and valve cover by means of which exterior control circuitry can be electrically coupled to electrical or electronic devices disposed internally of the valve cover. In a first embodiment, the wires connecting the devices to the control unit are simply molded into the gasket whereas in a second embodiment, the gasket is drilled or molded to provide holes for inserting the wires, sealing of the wires being accomplished by clamping of the gasket and/or sealant disposed on the wire. In another embodiment, a plastic carrier is provided having transversely extending spacing ribs in which the wires may be laid and covered with a room temperature vulcanizing compound as a sealant.
