  • Patent number: 6142257
    Abstract: An oil pickup tube includes a substantially straight portion, and a top and bottom portion interconnected with the straight portion. Each portion includes a cavity in fluid flow communication with the cavities of the other portions. Each cavity includes a substantially linear longitudinal axis. The cavities also include draft angles to allow the respective portions to be manufactured by injection molding, casting, or another suitable method. The top portion includes at least one recess adapted to receive a sealing member that creates a press-fit seal when the top portion is inserted into an oil gallery of an engine. Top and bottom flanges interconnected with the oil pickup tube facilitate securing the tube to the engine. A method for manufacturing the oil pickup tube includes the steps of defining the outer surface of the tube with a die, inserting two cores corresponding to the respective cavities of the top, straight, and bottom portions into the die, and delivering molten material into the die.
