Hi James,
Here is an exploded view of the distributor. The most common cause of leaking would be the 2 pcs of "O" rings and the oil sela insode the housing. The size of the seal should be 12.5 x 22.5 x 7 mm
Bruce is correct, using O rings 1/2 a size thicker works. Distributor position for this model is fixed so you do not have to worry about the installation. However if you were to replace the oil seal, make sure you mark the rotor position in relation to the rear coupling. Failure to do so could result in rotor 180 degrees off the mark.
