Abstract:
An oil drain tube disposed and connected between a turbocharger and an engine block for providing a fluid communication conduit includes a hollow tubular member having a first insertion end which is receivable within an engine block bore, and a second opposite mounting end having a flange for attaching the oil drain tube to the turbocharger. The insertion end of the oil drain tube having a sealing portion which includes two annular grooves with O-rings circumferentially mounted therein, and a stop portion defined by an annular protuberance formed adjacent to the annular grooves of the tubular member. A leak proof connection is provided at the engine block. The protuberance formed on the drain tube abuts the engine block when the drain tube is connected thereto and limits the axial insertion of the drain tube into the bore. The mounting end of the drain tube is spaced axially apart from the insertion end of the drain tube by a flexible tubular portion which enables a service technician to bend the tube as required during installation. The flange, having opposing clearance holes formed therein, is captured on the mounting end of the drain tube.
