  • Patent number: 7040274
    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).
