Zusammenfassung:	Methods and systems for metal-to-metal sealing and, in particular, to the use of sintered parts to create metal-to-metal sealing joints is disclosed. In one example, a metal-to-metal sealing joint may comprise: a first mating surface and a second mating surface; wherein the first mating surface is formed on a first assembly having an annular projection with one or more annular grooves and the second mating surface is formed on a second assembly; wherein the projection is configured such that when the first and second surfaces are brought into mating contact, the annular projection on the first mating surface deforms the second mating surface to form a sealing joint. In this way, the metal-to-metal sealing joint between the first and second mating surfaces may minimize oil leakage between two assemblies, thereby improving engine fuel economy while simplifying part manufacturing.
