    Abstract: A system and method for fluidly sealing a cylinder head interface between an engine block and a cylinder head of an internal combustion engine. An example apparatus includes a perimeter seal disposed on an outer periphery of the cylinder head. The perimeter seal has a first surface to abut a cylinder head sealing surface and a second surface to abut an engine block sealing surface. The perimeter seal is configured to prevent fluid from an external environment from entering the cylinder head interface and to allow fluid within the cylinder head interface to vent to the external environment when the fluid is above a predetermined pressure. A first fluid transfer tube seal fluidly seals a first fluid transfer orifice extending between the engine block and the cylinder head. The perimeter seal and the first fluid transfer tube seal are formed as a unitary structure.

    Abstract: A pin comprising a conical body having a central axis and a cross-sectional area that decreases with distance from a first end to a second end. A coating applied to the conical body has a melting temperature that is lower than a melting temperature of the conical body. The coating melting temperature is lower than a friction temperature and the body melting temperature is higher than the friction temperature. The friction temperature is achieved at an interface of the pin and a component when the pin is forcibly positioned into the component to repair a defect. The coating comprises a material having a first tensile strength value of a bond formed between the conical body and the component in response to softening and rehardening of the coating.

    Abstract: A method for repairing a multi-valve cylinder head, having a fuel injector or spark plug, or pre-chamber opening near the valve openings, that provides an insert with structural integrity that is capable of providing for both a repair for the crack and injector sleeve functionality in the finish-machined cylinder head. The present invention overcomes the consequences and structural limitations typically confronting larger diameter configurations while providing for a reliable sealing approach.

    Abstract: An injector bore insert includes a proximate portion adjacent to a combustion face and a distal portion including an upper threaded outer diameter. The injector bore insert further includes an angled conical collar, a remote threaded portion along an upper bore portion, a circumferential slot extending distally from approximately the combustion face, and one or more sealing regions. Each sealing region is positioned on the injector bore insert to facilitate sealing between the injector bore insert and a cylinder head of an internal combustion engine.
