valve seals??

Ok,a little update for you all.
I did a compression check on all cylinders(with all plugs removed,open throttle with engine at normal operating temperature)Here are the results

cylinder 1-110 psi

2-110 psi

3-110 psi

4-120 psi(!)
5-110 psi
6-110

Ok,about cylinder 4,When I pulled the plug out of it,smoke came out and it was saturated with oil.Im guessing(you can correct me) that a leak in the valve stem seal or valve guide is seeping into cylinder 4 which explains the high compression reading(since the oil from the leak is sealing the ring)
All of the other plugs are not oil fouled,only #4.So what says you guys?I know the compression readings are pretty low,what are the readings for a normal /6,I cant find any documentation anywhere.Could I get away with installing new valve stem seals and guids,or should I just do a complete overhaul.Right now ,my budget restrains me from a complete overhaul and rebuild.Other than the smoke problem and the leak,the car runs great and purrs like a kitten.Starts right up with just a pump of the throttle.
Im open to advice.=)
