An improved oil pan in combination with an internal combustion engine is disclosed. The oil pan has no drain outlet for permitting lubricating fluid to be drained away. The oil pan must be removed from the engine in order to replace the engine fluid. The oil pan is connected to the underside of the engine by a plurality of clamps such that each clamp applies clamping forces in a direct substantially perpendicular to the line defined by the points where the oil pan contacts the underside of the engine in the region proximate to the clamp.

In combination in an internal combustion engine: an oil pan adapted for readily-removeable connection to an underside of the engine; and a plurality of readily-releasable clamping means; wherein: the oil pan is adapted to contain a lubricating fluid; the oil pan has an upper opening having an oil pan periphery; the oil pan has no outlet for removing lubricating fluid such that the oil pan must be removed from the underside of the engine in order to replace lubricating fluid in the oil pan; the underside of the engine has a lower opening having an underside periphery; the underside periphery is substantially the same size, shape and configuration as the size, shape and configuration of the oil pan periphery, such that when in combination the oil pan periphery is in contact with substantially all portions of the underside periphery; each clamping means applies a clamping force in a direction substantially perpendicular to a line defined as being the points where the oil pan periphery contacts the underside periphery in the region proximate to the clamping means; and the clamping force of each clamping means is obtained by means other than bolts or screws.
