ABSTRACT:
A dual purpose, multi-layered steel intake/exhaust manifold gasket is constructed from a rubber coated embossed single-layer intake manifold gasket attached to an uncoated embossed double-layer exhaust manifold gasket. The gaskets overlap at several discontinuous locations along a common edge by sandwiching the single layer intake manifold gasket between the two layers of the exhaust manifold gasket. Holes are provided in the rubber coated single layer at some of the overlapping locations to allow the two layers of the exhaust manifold gaskets to contact and be fastened together. An air gap is left between the two gaskets except for the areas of overlap to control heat transfer between the gaskets.
