If an owner of a 1989 or 1990 Chevrolet Cavalier with a cable driven instrument cluster has a concern of an oily appearance on the face of the cluster or possibly on the driver's shoe, this may be caused by transaxle oil intrusion up the speedometer cable and into the vehicle.
If inspection shows that this is the cause, replace the vehicle speed sensor, speedometer cable and cluster.
