can worn valve guide seals cause rough idle?

When i changed the spark plugs on my 300e, I found oil on them. I would suspect the valve guide seals need to be replaced. My car also seems to have a rough idle. I then put in fresh plugs and the idle improved. After several thousands of miles the rough idle returned. Could this be caused from the worn valve guide seals?
