  • Engine with sealing head seat ring
    Patent number: 4762103
    Abstract: In a diesel engine having an angled cylinder bank with an individual cylinder head received on a sloping mounting surface over which return oil flows, a cylinder head wear ring or seat ring is provided to accept wear between the head mounting flange and the mounting surface. The seat ring is modified to incorporate around its outer periphery a seal having resilient beads that engage the opposed mounting and head flange surfaces to prevent oil from passing through the joint and entering the engine exhaust system.
