I was once told basically the same thing and in such a way that it sounded like a potentially serious problem, even though the car wasn't leaving any spots at all or using/loosing any oil.
When I had my plenum off to replace all six injectors and EGR valve, I checked things out (they looked very dry) and just to be sure, cautiously tightened the Philips head screws that hold down the valve covers and a few months before I replaced the front camshaft and crankshaft oil seals, when replacing the water pump, timing belts and accessory belts. With the front and back timing belt covers off, I did see evidence of a couple of small oil seal leaks, but still the car wasn't leaving any spots.
If you decided to replace your valve cover gaskets you'd want to do a lot of other very costly work at the same time, and that could be the BIG BUCKS that they are really after. Either that or you'd simply decide that buying a new car from them would make more sense.
