It could be your friend meant "valve guide seals." Valve cover gaskets cause external leaks onto the ground. Valve guide seals are internal, and help slow the flow of oil down the valve guides into the combustion chamber. Although 50k MIGHT be a bit soon for them to go, if you drive in a hot climate or keep the engine wound pretty tight, it would not be unheard of. How's the oil consumption? Bad seals often cause a lot of oil to be burned with little or no apparent smoke.
Best of luck with this!
