A valve stem oil seal comprises a cup-shaped case engageable with the valve guide of a piston-type internal combustion engine in sealing relationship. A seal element has a radial flange portion disposed between a radial flange on the case and a support washer so as to be radially movable relative thereto and an annular portion sealably engaged with the valve stem.

A spaghetti seal for use in a surface to be sealed to a confronting surface and having a pair of projecting beads for sealing against the confronting surface. The beads are molded to incline inwardly towards each other or when installed are caused to incline towards each other. Under load, the beads are forced in contact with each other in a controlled manner. When in contact they behave essentially as a single bead to provide increased stiffness and more effective sealing.

A spaghetti seal for use in an engine sealing assembly includes a stiffening member secured to an elastomeric member. The elastomeric member is adapted for mating engagement with the stiffening member. The stiffening member provides quick and easy installation of the spaghetti seal into a narrow groove formed in an engine part.

A valve cover gasket assembly for an automotive engine includes a rigid core having a plurality of pairs of notches, with each pair comprising one notch on the inner edge of the core and one notch on the outer edge. The assembly further includes a rigid stop member for each pair of notches, each stop member having a portion defining a fastener hole and a spaced apart lug. The stop members are secured to the core by engagement with the notches. When secured in this manner, the portion of each stop member defining the fastener hole is offset laterally from the core. An elastomeric envelope having elastomeric beads is applied over the core and a portion of each stop member, so that the beads extend continuously around the length of the assembly.
