An aircraft engine oil filler apparatus includes a filler tube configured to be received through a wall of an oil tank such that an open upper end of the filler tube is accessible from outside of the oil tank and a bottom end of the filler tube is disposed inside the oil tank, a valve received in the bottom end of the filler tube and movable between an open position in which the valve hydraulically connects the filler tube to the oil tank, and a closed position in which the valve hydraulically disconnects the filler tube from the oil tank, and a float disposed above the valve and operatively connected to the valve to move the valve from the open position to the closed position when oil inside the oil tank rises to a predetermined level. A method of operation of an oil filler apparatus is also described.
