If the valve stem seals are bad the intake valves will "suck" oil into the cylinders.

How do bellows valves work?
Bellow is similar to a hollow flexible hose. It functions like a vertical diaphragm (parallel instead of perpendicular to valve stem). It seals with the valve stem at one end, and seals with the valve body at the other end. Therefore, it allows a small relative move between valve stem and body, but prevents fluid from leaking across bellow surface. The move pushes seat or stem tip for valve to close or open. --SteveX

How do you change valve seals on a Hyundai elantra 2006?
Valve stem seals? Either you change the valve stem, or you change the valve core. Depends on where your air is leaking from. If it's the valve core, you simply take a valve core removal tool or pocket screwdriver with a valve core removal end (either one can be had cheaply at an auto parts store), uncscrew the old valve core out, insert the new valve core, and tighten it in. If you're replacing the entire valve stem, best to let a tire shop do this, as your tire will have to be dismounted, remounted, and balanced again.
