Could well be stuff creeping up the thread rather than an oil leak. Spark plugs come with a crush washer. It could be that that is the problem. A new plug might be the answer or you can get spare washers (Ebay). Also, look at the head round the plug hole - if that's not even, and the washer isn't seating properly you could get leaks. You could easily make up a tool to dress this.
Classic C5 Euro 4 at the moment.
