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.
did you check the condition of the valve stem seals while you had the head off? bad valve stem seals will allow oil to leak into inlet manifold . the head needs to be off to change valve stem seals
To replace the valve stem seals with the head on you must bring each cylinder up to top dead center, pressurize the cylinder with an air chuck screwed into the spark plug hole. (this prevents the valves from dropping into the cylinder) Now the seals on that cylinder can be replaced. The process is repeated on each cylinder. Note: you must prevent the engine from rotating when the cylinder is pressurized.
