I used this stuff called Risiline or something like it. Worked wonders for me. Picked up a bottle (It's in a yellow container) for about 5-6 bucks.
Ran it in my eclipse after driving on the same oil for over 20 thousand miles. Changed the oil again after about 1,000 and it almost looked new in there. Hope that helps.
BTW Lance, that is what my Zetec has always looked like (minus the difference in engine components) ever since I've used Syntec.
