Oil from the timing gear area comes from two sources: the crankshaft gear (thrown oil dribbling down and over the crankshaftgear and carried up onto the fiber gear) and a port cast in the engine block between the valve chamber and the timing covers area.

Some engine blocks have a "dam" at the front of the valve chamber. Apparently Ford experimented with the height of the oil pipe connection and the height of this dam in attempting to "even out" oil coverage in the valve chamber.

More likely your fiber gear has had the oil "squeegee'd" off by the action of the crankshaft gear. This is normal, happens with all gears, and given the fiberous content and surface appearance of the gear might give an erroneous impression?

You have a choice of chopped fiber gears, "slaked" fiber gears, aluminum gears and bronze gears for replacement.

I would go with slaked, although most who use aluminum and bronze "will never go back." The pricing, and gear longevity is increasing from left to right.
