Linking element for lubricant

The piston engine arrangement has an engine housing (25) and a lubricant reservoir (23), where a connecting element (24) is arranged for connecting the engine housing with the lubricant reservoir. A compensating element is provided with a sealing material (45), where one end (28) of a tubular piece (26) of the connecting element is partially accommodated. A fluid-tight connection is produced between the end of the tubular piece and the lubricant reservoir. An independent claim is also included for a vehicle with a vehicle housing.
