Abstract: A vibration isolation and sealing gasket for a cover mountable on a vibratable engine includes a pair of identical, oblong bead-shaped sealing portions, connected by a rectangular intermediate flange portion, sealingly positioned beneath the outer periphery of the cover. The intermediate portion has a plurality of convolutable, cylindrical protrusions extendable through clearance holes in the cover and having through holes concentric therewith for the insertion of bolts to convolute the protrusions and secure the cover to the engine. The protrusions further include integrally molded sleeves of a predetermined length to maintain predetermined minimum convoluted and compressed thicknesses of the gasket so as to maintain substantially equal spring rates in the convoluted and compressed portions of the gasket when the cover is tightly secured to the engine.
