i put a thread up about this a couple of months ago maybe..... I changed my rocker cover gasket(s) but havent rechecked any of the plugs yet to see if thats all it was. So really, of little help to you. It's a very easy job to do though.

Is the actual electrode oily and dirty?  If not it's probably just a cam cover gasket or someone has been kack handed when filling up with oil.

The threads on the plug dont seem to be covered in oil so i doubt it was due to it been loose,looks more likely to be the rocker gasket but thats not too bad to do.
