Abstract: For attaching the oil sump (10) to the engine block (30) of a combustion engine, a seal is made between the engine block (30) and the oil sump (10) by means of a curable composition (20). The adhesion of the composition (20) when cured is sufficient to secure the oil sump (10) to the engine block (30). The adhesion should be at least 0.5 N/mm2, especially more than 0.8 N/mm2. The curable composition (20) can be a silicone composition. The oil sump (10) can be fixed to the engine block (30) at least during the curing of the composition (20). To this end, the edge of the oil sump can be designed such that a self-fixing takes place when the oil sump (10) is joined to the engine block (30).

Abstract: For manufacturing a seal between two machine parts (10, 11) which together enclose a space (14) in which, at least at times, high pressure and/or high temperature prevail, sealing means which contain a curable composition (30) are arranged between the two machine parts (10, 11). The curable composition (30) is applied directly onto one or both machine parts (10, 11) in liquid form at least in the area which does not directly adjoin the space (14) in which, at least at times, high temperature and/or high pressure prevails. The two machine parts are built in before the curing of composition (30). A sealing ring can be inserted between the two machine parts (10, 11) directly around the edge of the high pressure and high temperature space (14) or that edge can be slightly raised and the curable composition (30) can be used for sealing outside this area.
