An improved gasket assembly including a core layer and at least two facing layers disposed on opposite sides of the core layer is provided. The gasket assembly further includes first and second outer layers which are made of metal and are disposed on opposite sides of the facing layers from the core layer. The core, facing and outer layers all present at least one set of axially aligned openings. The first layer is bent towards the second layer by no greater than ninety degrees at the openings to present a first outer layer flange, and the second layer is bent by no greater than ninety degrees at the openings to present a second outer layer flange. The first and second outer layer flanges are in direct contact with one another to provide a gas tight seal around the set of axially aligned openings.

Multi-layer gasket assembly

A gasket body has a combustion opening and a coolant opening close to the combustion opening to define a narrow region of the gasket between the openings. An inner armor layer has an inner C-shaped section folded over an edge of the combustion opening adjacent to the coolant opening. The inner armor layer has top and bottom portions extending over the top and bottom surfaces of the narrow region of the gasket body. An outer armor layer has an outer C-shaped section folded over the inner C-shaped section. The outer armor layer has top and bottom portions extending over the top and bottom portions of the inner armor layer. The bottom portion of the outer armor layer extends across the entire width of the bottom surface of the narrow region of the gasket body and has a second C-shaped section folded up and over an edge of the coolant opening adjacent to the combustion opening.
