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.

Claim (Index 23):
A method of installing a cylinder head seal apparatus on an internal combustion engine, the method comprising:\n providing an engine block of the internal combustion engine, the engine block defining a cylinder bore and a first fluid transfer orifice; positioning a combustion seal on the engine block coaxial to the cylinder bore; positioning a cylinder head seal apparatus on the engine block such that a fluid transfer tube seal of the cylinder head seal apparatus is disposed within a first counterbore adjacent and coaxial to the first fluid transfer orifice; aligning a cylinder head of the internal combustion engine relative to the engine block such that the fluid transfer tube seal is disposed within a second counterbore adjacent and coaxial to a second fluid transfer orifice of the cylinder head, the fluid transfer tube seal providing fluid communication between the first and second fluid transfer orifices; and fastening the cylinder head to the engine block to sealingly engage the cylinder head seal apparatus between the engine block and the cylinder head.
