I'm sure it happens - what is needed is some empirical data to show how long it takes for the oil pressure to drop below the minimum safe level. How much negative g is needed to lower the oil pressure enough to cause damage? The Pilot's Notes General, for example, describes one condition imposing too much negative g is a succession of slow rolls - so how many pilots are going to indulge in successive slow rolls during combat? What other combat conditions will impose enough negative g for long enough to damage the engine?

The normal oil pressure for the Merlin is 60lbs/sq.in, with a working minimum of 30lbs/sq.in. For gameplay a rough rule of thumb could be anything below 30lbs and the engine begins to suffer progressive wear (according to the Pilot's Notes General it doesn't take long for damage to occur once the oil pressure drops below the minimum).
