Remove the LH and RH spark plugs.





61. Install the crankshaft pulley bolt.





62. Rotate the crankshaft clockwise to position the crankshaft keyway in the 11 o'clock position and position the camshafts in the correct position. This will position the No. 1 cylinder at top dead center (TDC).
^ Verify that the camshafts are correctly located. If not, rotate the crankshaft one additional turn and recheck.





63. Rotate the crankshaft clockwise 120 degrees to the 3 o'clock position to position the RH camshafts in the neutral position.





64. Verify that the RH camshafts are in the neutral position.





65. Remove the RH timing chain tensioner arm.
1. Remove the 2 bolts.
2. Remove the tensioner.
3. Remove the tensioner arm.





66. Remove the bolts, RH timing chain guide and the timing chain.





67. Rotate the crankcase clockwise 600 degrees (1-2/3 turns) to position the crankcase keyway in the 11 o'clock position. This will position the LH camshafts in the neutral position.





68. Verify the LH camshafts are in the neutral position.





69. Remove the LH timing chain and tensioner arm.
1. Remove the 2 bolts.
2. Remove the tensioner.
3. Remove the tensioner arm.





70. Remove the LH timing chain and timing chain guide.





71. Remove the crankshaft pulley bolt and the crankshaft sprocket.





72. Remove the 4 bolts in the sequence shown.
^ Remove the oil pump.

73. NOTICE: Do not scratch the camshaft sealing surface while removing the camshaft oil seal. If scratched, camshaft oil seal leakage may occur.





Using the special tools, remove the camshaft oil seal and discard.





74. Remove the 2 bolts and the camshaft oil seal retainer.
^ Discard the press-in-place gasket.

75. NOTICE: Cylinder head camshaft bearing caps must be assembled in their original positions. Some engines have factory markings on the camshaft bearing caps (as shown in illustration). Engines that do not have the factory markings must be marked for correct position and orientation prior to removal. Failure to install the camshaft bearing caps in their original position may result in severe engine damage.





If necessary, mark the camshaft bearing cap position and orientation as shown in the illustration.

76. NOTICE: After loosening all of the camshaft bearing cap bolts, remove the camshaft bearing thrust caps (1L and 6L) first, or damage to the thrust caps may occur.

NOTE: Make sure the camshaft bearing caps are marked as instructed in the previous step.





Loosen the bolts evenly in the sequence shown.
1. Remove the camshaft bearing thrust caps (1L and 6L).
2. Remove the remaining camshaft bearing caps.
3. Remove the camshafts from the cylinder head.

77. NOTICE: Cylinder head camshaft bearing caps must be assembled in their original positions. Some engines have factory markings on the camshaft bearing caps (as shown in illustration). Engines that do not have the factory markings must be marked for correct position and orientation prior to removal. Failure to install the camshaft bearing caps in their original position may result in severe engine damage.





If necessary, mark the camshaft bearing cap position and orientation as shown in the illustration.

78. NOTICE: After loosening all of the camshaft bearing cap bolts, remove the camshaft bearing thrust caps (5R and 1R) first, or damage to the thrust caps may occur.

NOTE: Make sure the camshaft bearing caps are marked as instructed in the previous step.





Loosen the bolts evenly in the sequence shown.
1. Remove the camshaft bearing thrust caps (5R and 1R).
2. Remove the remaining camshaft bearing caps.
3. Remove the camshafts from the cylinder head.

79. NOTICE: The camshaft roller followers must be installed in their original positions. If not reassembled in their original positions, severe engine damage may occur.

NOTE: RH shown, LH similar





Remove the LH and RH camshaft roller followers.
^ Mark the location of the roller followers, using a permanent-type marker.

80. NOTICE: The hydraulic lash adjusters must be installed in their original positions. If not reassembled in their original positions, severe engine damage may occur.

Remove the hydraulic lash adjusters.

81. NOTE: RH shown, LH similar





Loosen the bolts in the indicated sequence and remove the LH and RH cylinder heads.
^ Discard the bolts and the gaskets.

82. NOTICE: Do not use metal scrapers, power abrasive discs or other abrasive means to clean the sealing surface. These tools can cause scratches and gouges, which make leak paths.

Clean the cylinder head gasket surfaces with a plastic scraping school and metal surface prep.

83. Support the cylinder head on a bench with the head gasket side up. Check the cylinder head distortion and the cylinder block distortion.





84. Remove the bolts and the oil separator cover.
^ Discard the gasket.





85. Remove the crankshaft key.

86. Before removing the pistons, inspect the top of the cylinder bores. If necessary, remove the ridge of carbon deposits from each cylinder using and abrasive pad or equivalent, following manufacturer's instructions.

87. NOTE: Clearly mark the position and orientation of the pistons, connecting rods, connecting rod caps and connecting rod bearings for assembly.





Remove the connecting rod cap bolts and cap.
^ Discard the connecting rod cap bolts.

88. NOTICE: Do not scratch the cylinder walls or crankshaft journals with the connecting rod.





Using the Connecting Rod Installer, remove the piston/rod assembly from the engine block.
^ Repeat these 2 steps until all the piston/rod assemblies are removed from the engine block.

89. Remove the engine block from the stand and place on a workbench.





90. Remove the bolts and studs in the indicated sequence.
^ Discard the lower cylinder block bolts
^ Remove the lower cylinder block.





91. Remove the crankshaft rear main seal.
^ Remove the crankshaft.





92. Remove the crankshaft thrust bearing from the cylinder block.

93. NOTE: If the main bearings are being reused, mark them for correct position and orientation for reassembly.





Remove the bearings from the lower cylinder block.

94. NOTE: If the main bearings are being reused, mark them for correct position and orientation for reassembly.





Remove the crankshaft main bearings from the cylinder block.

95. Inspect the cylinder block, lower cylinder block, pistons and connecting rods.
