A self closing valve for use with an engine that prevents the loss of fluid from a transmission connected to the engine when a magnetic chip detector is removed from the transmission housing. The self closing valve and magnetic chip detector being integrated together to form a magnetic chip detection system that provides an indicating signal to the operator of an aircraft when magnetically attractable debris is detected in the transmission. The self closing valve includes a pair of valve doors that rotate about a pivot point so as to be moveable from a central region of a passageway within the transmission housing. Further, the valve does not extend substantially into the interior of the mechanical housing but is closeable to prevent loss of fluid from the interior of the mechanical housing when the magnetic chip detector is withdrawn from the passageway.
