Any leaks from top side of engine should be repaired for the following reasons: --Oil and rubber don't go well together...the rubber belts will not only deteriorate faster, but oil will cause them to slip. --Oil or any other fluids should not be allowed into any electrical component including alternator...may cause shorts or unpredicatable wear on components

I own a 91 LS 400 and the speedo does not move. Everything else in the instrument cluster, including odometer is working fine. I have replaced the speedometer housing at the transmission and still no good. Anyone have any idea before I tear apart the inst cluster? Any available clusters out there?
