MichaelB Posted April 10, 2005 Share Posted April 10, 2005 I have a '99 Legacy with 75K miles on a 2.2 liter engine. Changing the spark plugs today, the front-passenger plug wire was covered in oil. What could have caused this? Link to comment Share on other sites More sharing options...
Commuter Posted April 10, 2005 Share Posted April 10, 2005 Sounds like a leak from the valve cover gasket. There is an o-ring shaped gasket that seals the valve cover around the spark plug well. If it leaks, you will get oil around the plug and on the wire. Not uncommon. Commuter Link to comment Share on other sites More sharing options...
