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.
