Installation

1. NOTICE: Only use a 3M Roloc(R) Bristle Disk (2-in white, part number 07528) to clean the engine front cover. Do not use metal scrapers, wire brushes or any other power abrasive disk to clean front cover.

Clean the engine front cover using a 3M Roloc(R) Bristle Disk (2-in white, part number 07528) in a suitable tool turning at the recommended speed of 15,000 rpm. Thoroughly wash the engine front cover to remove any foreign material, including any abrasive particles created during the cleaning process.

2. 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(R) Bristle Disk (2-in white part number 07528) to clean the sealing surfaces of engine block, cylinder heads, and oil pan. These tools can cause contamination that will cause premature engine failure. Remove all traces of the gasket.

Clean the sealing surfaces of the cylinder heads, the cylinder block and the oil pan in the following sequence.

1. Remove any large deposits of silicone or gasket material.

2. Apply Motorcraft(R) Silicone Gasket Remover and allow to set for several minutes.

3. Remove the Motorcraft(R) Silicone Gasket Remover. A second application of Motorcraft(R) Silicone Gasket Remover may be required if residual traces of silicone or gasket material remain.

4. Apply Motorcraft(R) 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.

3. NOTE: Make sure the 2 locating dowel pins are seated correctly in the cylinder block.
Install 307-399.





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

NOTE: The engine front cover and bolts 7, 8, 15, 17, 18, 21 and 22 must be installed within 4 minutes of the initial sealant application. The remainder of the engine front cover bolts must be installed and tightened within 35 minutes of the initial sealant application. If the time limits are exceeded, the sealant must be removed, the sealing area cleaned and sealant reapplied. To clean the sealing area, use Motorcraft(R) Silicone Gasket Remover and Motorcraft(R) Metal Surface Prep. Failure to follow this procedure can cause future oil leakage.

Apply a 3 mm (0.1181 in) bead of Motorcraft(R) High Performance Engine RTV Silicone to the sealing surface of the front cover.

- Apply a 5.5 mm (0.22 in) bead of Motorcraft(R) High Performance Engine RTV Silicone to the oil pan-to-cylinder block joint and the cylinder head-to-cylinder block joint areas of the engine front cover in 5 places as indicated.






5. NOTE: Make sure the 2 locating dowel pins are seated correctly in the cylinder block.
Install the engine front cover and bolts 7, 8, 15, 17, 18, 21 and 22.
