Abstract
An embodiment provides a MLS gasket that includes a metal body portion having an external periphery, an upper body surface generally defining a first plane. At least one cylinder aperture formed in the metal body portion and defined by an inner aperture surface. The gasket also includes a combustion seal insert including a first insert layer having an outer first periphery, a top first insert surface and a bottom first insert surface. The outer first periphery is circumscribed by the inner aperture surface. The first insert layer includes a first insert bead portion. The gasket further includes a first sealing layer having a top first sealing surface and a bottom first sealing surface. Portions of the bottom first sealing surface are selectively in contact with each of the upper body surface and the top first insert surface. Compression of the first insert bead portion is selectively limited by the body portion.
