Likely cleaning it will be all it needs. In an extreme case where the plunger is toast, I recommend replacing the plunger
and reusing the original lifter body. The link I meant to give you is here
. It has more detail.
If the foot of the lifter is too worn, replacing the lifter w/a new one will likely result in a ruined cam and ground up metal all through the engine which can take out the bearings, or worse. In that case, replacement of the cam and all the lifters is called for.
