I would highly recommend doing a complete valve cover gasket/valve stem gasket change.

 

Both plugs look normal, just worn.

 

Glad others are finally agreeing with me! They look totally "normal"...according to that link.

 

the old plug in the left picture looks fine. The white picture has white on the tip which isn't too great. Now given, there are a lot worse looking plugs. But either way they NEEDED changing and have oil leaking in on them.

 

yes i do agree they look normal !!! so thanks for bringing that link to light!
