I have a rough idle problem and thought i'd change the spark plugs, i noticed the rightmost sparkplug's thread was covered in oil and the others werent. Only the thread had oil on it. Could this be a leak thats interrupting the spark to that last cylinder? Is there a seal or something I can replace? Any help appreciated, thanks.

Sounds like you need a new valve cover gasket. The 7A-FE has four o-rings that go inside the valve cover and seal the spark plug area from oil. You'll need to take the screws off the top and pry up the little washers underneath of them and remove the plastic trim that runs over the top of the valve cover. Your valve cover should come off. You'll want to replace ALL of the gaskets in/on the valve cover.
