Part 3
EngineDisassembly (Steps 57-84)
57. Remove the RH camshaft.
58. CAUTION: Remove the front thrust camshaft bearing cap straight upward from the bearing towers, or the bearing cap may be damaged from sideloading.
NOTE: The camshaft bearing caps must be installed in their original locations. Record camshaft bearing cap locations.
Remove the bolts in the sequence shown and remove the LH cylinder head front camshaft bearing cap and then the remaining bearing caps.
59. Clean and inspect the LH camshaft bearing caps.
^ The camshaft front thrust bearing cap contains an oil metering groove. Make sure the groove is free of foreign material.
60. Remove the LH camshaft.
61. CAUTION: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations.
Remove all of the remaining roller followers from the cylinder heads.
62. Remove the 2 bolts and the 2 knock sensors (KS).
63. Remove the stud bolt and the coolant tube.
^ Discard the O-ring seal.
64. CAUTION: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations.
Remove the hydraulic lash adjusters from the LH cylinder head.
65. Install the special tool onto the LH cylinder head.
66. Install the special tool onto the RH cylinder head.
67. Remove the stud bolt and the coolant tube.
^ Discard the O-ring seals.
68. CAUTION: The cylinder head must be cool before removing it from the engine. Cylinder head warpage can result if a warm or hot cylinder head is removed.
CAUTION: Place clean shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine.
CAUTION: The cylinder head bolts must be discarded and new bolts must be installed. They are tighten-to-yield designed and cannot be reused.
CAUTION: 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.
CAUTION: Aluminum surfaces are soft and can be scratched easily. Never place the cylinder head gasket surface, unprotected, on a bench surface.
NOTE: RH shown, LH similar.
Remove the bolts and the cylinder head.
^ Discard the cylinder head gasket.
^ Discard the cylinder head bolts.
69. CAUTION: 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.
CAUTION: 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.
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.
70. 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 inch) per running foot length. For example, if the straightedge is 61-cm (24-inch) long, the machined edge must be flat within 0.010 mm (0.0004 inch) from end to end.
NOTE: LH shown, RH similar.
Support the cylinder head on a bench with the head gasket side up. Inspect all areas of the deck face with a straightedge, paying particular attention to the oil pressure feed area. The cylinder head must not have depressions deeper than 0.0254 mm (0.001 inch) across a 38.1-mm (1.5-inch) square area, or scratches longer than 0.0254 mm (0.001 inch).
71. Remove the 4 bolts and the LH engine mount.
72. CAUTION: 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.
CAUTION: 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. Follow the directions on the packaging.
Remove the bolts and nut retaining the oil filter adapter to the cylinder block. Remove the oil filter adapter and clean the gasket surface.
73. Remove the bolts, the oil pan and discard the oil pan gasket.
74. Remove the 3 bolts, the oil pump screen and pickup tube and the spacer.
75. Remove the 3 bolts and the oil pump.
76. CAUTION: Make sure connecting rods and rod caps are numbered, to retain correct orientation.
Remove the bolts and the connecting rod caps.
^ Rotate the crankshaft so that the connecting rod is at bottom dead center.
^ Remove and discard the bolts.
77. CAUTION: Do not scratch the cylinder walls or the crankshaft journals with the connecting rod.
Remove the piston and rod assembly.
^ Using the special tools, guide the piston and rod assembly out of the cylinder.
78. Repeat the previous steps until all 10 piston and rod assemblies have been removed from the cylinder block.
79. Disassemble the 10 pistons.
80. Remove and discard the 12 cross-mounted bolts.
81. Remove and discard the bolts.
82. Remove the main bearing cap dowel pins.
83. Remove the main bearing caps, the lower crankshaft main bearings and the thrust washer.
84. Remove the crankshaft and the crankshaft main bearings from the cylinder block.
