Rear main seal Replacement?

Your Grand Prix is under factory recall for leaking valve cover gaskets. Have them do the recall for free and check for other oil leaks while it's there. If the lower intake manifold gaskets have not been replaced yet they could be leaking oil as well! Those usually fail between 90,000 and 120,000 miles. Hope that helps! Jim
