摘要： An engine is provided with a cylinder block and a ladderframe having a portion of an oil conduit and a deflector. The engine has a metal-to-metal seal positioned between the ladderframe and block to circumferentially surround the oil conduit, and has a gasket seal positioned between the ladderframe and block to be outboard and spaced apart from the oil conduit. The deflector is positioned between the metal-to-metal seal and the gasket seal. An engine component is provided with a member having a deflector and forming an oil conduit. The deflector has an arcuate deflector surface following an outer wall of the oil conduit to redirect oil escaping the oil conduit. A ladderframe is configured to provide a deflection surface, with the deflection surface positioned to guide high pressure oil away from adjacent RTV seals.

摘要： A gasket is provided with two dissimilar materials. The two different materials are used to provide different sealing characteristics. In one embodiment, the different sealing materials join to create the same or a similar profile to the profile of the individual materials. In another embodiment, the different sealing materials have the same profile but have joining portions that are complementary to one another where the two materials are joined to one another.
