Removal

NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02 .
  1. Remove the flexplate or flywheel. For additional information, refer to Flexplate or Flywheel in this section.
  1. Remove the crankshaft sensor ring.
  1. Remove the nut, the bolt and the heat shield.
  1. Remove the wiring harness retainer stud bolt.
  1. Remove the wiring harness grommet.
  1. Disconnect the Crankshaft Position (CKP) sensor electrical connector.
  1. Remove the bolt and the CKP sensor.
  1. Remove the 2 oil pan-to-crankshaft rear seal retainer bolts.
  1. Remove the 8 bolts and the crankshaft rear seal retainer plate.
  1. NOTICE: Place clean, lint-free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages or the oil pan, may cause engine failure.

    NOTICE: Do not use wire brushes, power abrasive discs or 3M™ Roloc® Bristle Disk (2-in white, part number 07528) to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. They also cause contamination that will cause premature engine failure. Remove all traces of the gasket.

    Clean the sealing surfaces of the cylinder block and oil pan flange in the following sequence.
    1. Remove any large deposits of silicone or gasket material.
    1. Apply silicone gasket remover and allow to set for several minutes.
    1. Remove the silicone gasket remover. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
    1. Apply metal surface prep to remove any remaining traces of oil or coolant and to prepare the surfaces to bond. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.

Installation

  1. NOTICE: Failure to use Motorcraft® High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.

    NOTE: The crankshaft rear seal retainer must be installed and the bolts tightened within 10 minutes of sealant application.

    Apply 5 mm (0.196 in) beads of Motorcraft® High Performance Engine RTV Silicone to the 2 cylinder block/oil pan joints.
  1. NOTICE: Failure to use Motorcraft® High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.

    NOTE: The crankshaft rear seal retainer must be installed and the bolts tightened within 10 minutes of sealant application.

    NOTE: The stamped steel crankshaft rear seal retainer plate comes with the crankshaft rear seal.

    Apply a 3 mm (0.11 in) bead of Motorcraft® High Performance Engine RTV Silicone to the sealing surface of the crankshaft rear seal retainer.
  1. NOTE: Use the 2 handles during installation to avoid touching the sealant.

    NOTE: Lubricate the crankshaft rear seal with clean engine oil.

    Install the crankshaft rear seal retainer at an angle above the oil pan flange to avoid scraping off the sealer. Tilt the seal retainer up and onto the rear of the cylinder block.
  1. Install the 8 bolts and tighten in the sequence shown to 10 Nm (89 lb-in).
  1. Install the 2 oil pan to crankshaft rear seal retainer bolts.
  1. Install the Crankshaft Position (CKP) sensor and install the bolt.
  1. Connect the CKP sensor electrical connector.
  1. Install the wiring harness grommet.
  1. Install the wiring harness retainer stud bolt.
  1. Install the heat shield, the nut and the bolt.
  1. Install the crankshaft sensor ring.
  1. Install the flexplate or flywheel. For additional information, refer to Flexplate or Flywheel in this section.
  1. After completing the repairs, use the scan tool to preform the Misfire Monitor Neutral Profile Correction procedure following the on-screen instructions.
