Are you sure its oil? Ford claims to have had the intake manifold problem fixed in '02, but that is pure garbage. Leaking (cracked) intake manifold or a bad intake gasket allow coolant to meander its way into the spark plug holes and snuffs out the spark causing CEL to come on. Seen this problem many times...

Possible bad rings, i would put some motor tune-up in oil will clean carbon off rings, its made by company called seaform and is called motor tune-up, put hole can in oil and drive for about 30 days ,its good stuff can also use in fuel to clean injectors, could also have worn out valve stem seals causing oil to leak pass valves into cyl
