Engine Front Cover: Installation

  1. NOTE: Only use a 3M™ Roloc ® 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 the engine front cover.

    Clean the engine front cover using a 3M™ Roloc ® 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. NOTE: 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.
    NOTE: Do not use wire brushes, power abrasive discs or 3M™ Roloc ® Bristle Disk (2-in white, part number 07528) to clean the sealing surfaces of the engine block, cylinder heads, and oil pan. These tools cause contamination that can cause premature engine failure. Remove all traces of sealant, including any sealant from the inner surface of the cylinder block and cylinder head.
    NOTE: Observe all warnings or cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.

    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 with a plastic scraper.
    2. Apply silicone gasket remover, following package directions and allow to set for several minutes.
    3. Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
    4. Apply metal surface prep, following package directions, 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.
    5. Make sure the 2 locating dowel pins are seated correctly in the cylinder block.

  3. Install the Alignment Pins.

  4. NOTE: Failure to use the correct RTV Silicone Sealant (TA-357) may cause the engine oil to foam excessively and result in serious engine damage.
    NOTE: The engine front cover and bolts 17, 18, 19 and 20 must be installed within 4 minutes of the initial sealant application. The remainder of the engine front cover bolts and the engine mount bracket 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 silicone gasket remover and metal surface prep. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.

    Apply a 3.0 mm (0.11 in) bead of RTV Silicone Sealant (TA-357) to the engine front cover sealing surfaces including the 3 engine mount bracket bosses.

    • Apply a 5.5 mm (0.21 in) bead of RTV Silicone Sealant (TA-357) 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.
