ABSTRACT:
An oil pickup tube assembly for an internal combustion engine comprises a two-piece structure including a base member which attaches to an oil intake or inlet of an engine and includes an elbow therein permitting angling the inlet end of the pickup member into the appropriate position within a sump area of the oil pan. The pickup member comprises a U-shaped tube, one end of which engages the base member and another end of which depends into the sump area, with the inlet end being supported by a bracket attached to the crankcase. The interface between the tube and the base member includes an O-ring seal, with the tube and base member being releasably locked together by relative rotation therebetween and a tab and slot engagement formed between the pieces to permit a certain amount of stress-free misalignment between the base member and the pickup member.
