Method for monitoring an anti-leak valve of a circuit for supplying oil between an oil reservoir and elements to be lubricated of a jet engine, comprising steps of: measuring oil level values in the reservoir, at the beginning and at the end of starting the jet engine; calculating the difference between the measured oil levels, to form a measured change in the oil level; measuring an oil temperature value; determining an estimated change of the oil level in the reservoir, depending on the oil temperature; calculating the difference between the measured change and the estimated change in the oil level for the measured temperature; comparing the calculated difference with a detection threshold; and activating an alarm depending on the result of the comparison.
