ABSTRACT:
End seals having a large compressibility range are mounted by their adhesive underlayer to support surfaces of an engine block and are formed with transverse notches in opposite ends to receive a given quantity of silicone or other suitable sealant. The end seals mate with intake manifold gaskets which may have notches therein that align with the notches of the end seals for receiving the sealant. The end seal, the head and intake manifold gaskets terminate at junctures of the engine block, cylinder heads and manifold which define recesses therebetween providing potential oil leak paths. These paths are effectively sealed as the manifold is connected to the cylinder head and block assembly causing the end seals to be compressed and the sealant to be squeezed into the recesses so that the gaskets and the end seal are joined in an oil sealing manner. With this construction, the sealants are confined in the covered recess providing not only repeatable high quality seals for size variations occurring with quantity production but also a finely finished appearance.
