Crankshaft Rear Seal with Retainer Plate: Installation

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
    CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.
    NOTE: Clean sealing surfaces with metal surface prep. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer, failure to follow this procedure can cause future oil leakage.
  1. Clean and inspect the mating surface.
    2. NOTE: The rear crankshaft seal retainer plate does not have a sealant groove. Gasket maker must be applied to the rear crankshaft seal retainer mating surface on the engine block.

    7. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges, which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.
  7. Inspect the oil pan. Clean the mating surface for the oil pan with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
  8. Position the oil pump screen and pickup tube in the oil pan and position the oil pan and new gasket into the vehicle.
    9. CAUTION: Make sure to install a new O-ring seal. A missing or damaged O-ring seal can cause foam in the lubrication system, low oil pressure and severe engine damage.
    NOTE: Clean and inspect the mating surfaces and install a new O-ring seal. Lubricate the O-ring seal with clean engine oil prior to installation.
  9. Position the oil pump screen and pickup tube and install the bolts.
    • Tighten the oil pump screen and pickup tube-to-oil pump bolts to 10 Nm (89 lb-in).
    • Tighten the oil pump screen and pickup tube-to-spacer bolt to 25 Nm (18 lb-ft).
    10. NOTE: If the oil pan is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can result in future oil leakage.
