Service Procedure

  1. Inspect the lower portion of the engine for any signs of an oil leak. Refer to Workshop Manual (WSM), Section 303-01. If necessary, clean the engine, add fluorescent dye and inspect for the source of the oil leak. Are there signs of an oil leak in the area of the upper oil pan near the engine block to upper oil pan joint?

(1). Yes – proceed to Step 2.

(2). No – this article does not apply. Refer to Workshop Manual (WSM), Section 303-00 for further diagnostics.

  1. Clean the engine, add fluorescent dye to the engine oil and inspect for the source of the oil leak. Refer to WSM, Section 303-01. Is the dye present leaking from the mating surfaces of the upper oil pan and on the engine block assembly?

(1). Yes – proceed to Step 3.

(2). No – this article does not apply. Refer to WSM, Section 303-00 and any other applicable service communications for further oil leak diagnostics.

  1. Remove the upper engine oil pan. Refer to WSM, Section 303-01.

CAUTION: Cleaning and preparation of the engine sealing surface is absolutely critical for proper adhesion of the upper oil pan. Improperly cleaned and prepared sealing surfaces results in an oil leak.

  1. Thoroughly clean the engine sealing surface using Motorcraft® Silicone Gasket Remover and a plastic scraper. Allow the gasket remover to set for several minutes after application to aid in the removal of the RTV sealant.

(1). The engine block skirt stiffener and upper oil pan sealing surfaces must be clean and free of any residual RTV. Do not use metal scrapers, wire brushes, or rotary tools of any type on the engine sealing surface. These tools damage the sealing surfaces including scratches or gouges that create leak paths. A second application of Motorcraft® Silicone Gasket Remover may be required.

NOTE: Use a lint-free cloth when cleaning the engine block and upper oil pan sealing surfaces. Spraying the surfaces with brake cleaner and air drying does not adequately remove the oil and other contamination from the surfaces and may leave residue from the brake cleaner behind that may interfere with RTV adhesion.

  1. Use a lint-free towel and Motorcraft® Metal Brake Parts Cleaner to remove all residual sealant and oil from the engine and upper oil pan sealing surfaces until a clean lint-free towel no longer shows any residual oil when wiping the surface.

(1). Use only Motorcraft® Metal Brake Parts Cleaner to clean the upper oil pan and engine block sealing surfaces. Some unapproved brake parts cleaners contain chemicals that inhibit RTV adhesion or may evaporate without removing all of the residual oil from the sealing surface which results in a repeat leak condition.

  1. Wipe the metal engine block skirt stiffener and upper oil pan sealing surfaces using Motorcraft® Metal Surface Prep Wipes. Thoroughly coat the surface with the fluid. Discard the wipes after a single use.

(1). Motorcraft® Metal Surface Prep Wipes create a conversion coating providing an improved base for RTV sealing. The Motorcraft® Metal Surface Prep Wipe fluid is a water-based, slightly acidic solution that etches and bonds to the metal to provide a microscopic layer to which the RTV sealant can adhere. If the surface is oily, the solution beads, indicating the surface is not clean. If the solution beads when applied to the sealing surface, clean the surface again with Motorcraft® Metal Brake Parts Cleaner and a lint-free towel and wipe the surface with Motorcraft® Metal Surface Prep Wipes.

  1. Allow the surface to air dry for approximately 2 minutes.

(1). Do not dry the surface using any other method. Attempting to dry the surface may result in sealing surface contamination that may cause oil leaks.

  1. Install the 3 new press-in-place oil pump gaskets. Refer to WSM, Section 303-01.

CAUTION: Install the upper oil pan within 10 minutes of applying the RTV. Prior to installing the upper oil pan, check for any additional oil that has drained from the engine and clean as necessary. Failure to do so could result in a repeat repair.

  1. Apply a 4.5 mm (0.18 in.) bead of Motorcraft® High Performance Engine RTV Silicone to the upper oil pan. Make sure the RTV bead straddles the step chamfer and sealing face.

(1). Using too little sealant may result in oil leaks and using too much sealant may result in oil contamination and engine damage.

  1. Apply a 9 mm (0.35 in.) bead of Motorcraft® High Performance Engine RTV Silicone to the engine front cover-tocylinder block joint areas on the upper oil pan.
  2. Install the upper oil pan. Refer to the WSM, Section 303-01.
  3. Perform Steps 4-7 on the upper oil pan surface to prep the surface for installation of the lower oil pan.
  4. Apply a 4.5 mm (0.177 in.) diameter bead of Motorcraft® High Performance Engine RTV Silicone on the outside of the chamfer on the new lower oil pan sealing face. Install the lower oil pan within 10 minutes of applying the RTV sealant.

(1). Using too little sealant may result in oil leaks and using too much sealant may result in oil contamination and engine damage.

  1. Install the new lower oil pan. Refer to WSM, Section 303-01.
