NOTE: Remove the cylinder heads before removing the crankshaft. Failure to do so can result in engine damage.
NOTE: 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.
NOTE: The flywheel, crankshaft rear oil slinger, crankshaft rear seal and crankshaft rear seal retainer plate must be removed before mounting the engine on the engine stand.
NOTE: For additional information, refer to the exploded view under the ASSEMBLY  procedure.
  1. Remove the 8 flywheel bolts.
  2. NOTE: The flywheel is a press fit on the crankshaft pilot. Do not use screwdrivers or prybars to remove the flywheel or damage to the flywheel or engine may occur.

    Remove the flywheel.

  100. NOTE: 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 that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.
    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.
    NOTE: If there is no residual gasket material present, metal surface prep can be used to clean and prepare the surfaces.

    Clean the cylinder head-to-cylinder block mating surfaces of both the cylinder head and the cylinder block 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 with the new gasket. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
  101. NOTE: Make sure all cylinder head surfaces are clear of any gasket material, RTV, oil and coolant. The cylinder head surface must be clean and dry before running a flatness check.
    NOTE: Use a straightedge that is calibrated by the manufacturer to be flat within 0.005 mm (0.0002 in) per running foot length. For example, if the straightedge is 61 cm (24 in) long, the machine edge must be flat within 0.010 mm (0.0004 in) from end to end.
    NOTE: LH shown in illustration, RH similar.

    Support the cylinder heads on a bench with the head gasket side up. Check the cylinder head distortion and the cylinder block distortion, paying particular attention to the oil pressure feed area. Refer to ENGINE SYSTEM - GENERAL INFORMATION .

  102. Before removing the pistons, inspect the top of the cylinder bores. If necessary, remove the ridge or carbon deposits from each cylinder using an abrasive pad or equivalent, following manufacturer's instructions.
  103. NOTE: Verify that the connecting rods and rod caps have orientation numbers cast into them. If not, number the connecting rods and rod caps for correct orientation.

    Remove the bolts and the connecting rod caps for pistons No. 1 and No. 6.

    • Carefully tap the connecting rod bolts out of the connecting rod caps. Avoid damaging the rod caps.
