Continued From Part 1 Part 1

CAUTION: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 may cause engine failure.





31. Install the crankshaft pulley bolt and washer.






32. 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.






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






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






35. Remove the RH timing chain tensioner arm.
a. Remove the 2 bolts.

b. Remove the tensioner.

c. Remove the tensioner arm.






36. Remove the 2 bolts and the RH timing chain guide.

- Remove the RH timing chain from the engine.






37. Rotate the crankcase clockwise 600 degrees (one and two-thirds turns) to position the crankcase keyway in the 11 o'clock position. This will position the LH camshafts in the neutral position.






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






39. Remove the LH timing chain and tensioner arm.
a. Remove the 2 bolts.

b. Remove the tensioner.

c. Remove the tensioner arm.






40. Remove the 2 bolts and the LH timing chain guide.

- Remove the LH timing chain from the engine.






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






42. Remove the 4 bolts in the sequence shown.

- Remove the oil pump.






43. Using the Oil Seal Remover, remove the camshaft oil seal and discard.

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






44. Remove the 2 bolts and the camshaft oil seal retainer.

- Discard the press-in-place gasket.






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

CAUTION:The camshafts must be in the neutral position before removing the bearing caps or damage to the engine may occur.






46. Remove the 3 bolts and the LH camshaft phaser and sprocket.

CAUTION:Do not allow the camshaft to rotate from the neutral position while removing the camshaft phaser and sprocket or damage to the engine may occur.
NOTE:Install a 3/8-in ratchet and extension into the D-slot on the rear of the intake camshaft to hold the camshaft in place for removal of the camshaft phaser and sprocket bolts.






47. Remove and discard the VCT system oil filter screen from the LH camshaft.






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

CAUTION: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 positions may result in severe engine damage.






49. Loosen the bolts evenly in the sequence shown.
a. Remove the camshaft bearing thrust caps (1L and 5L).

b. Remove the remaining camshaft bearing caps.

c. Remove the camshafts from the cylinder head.

CAUTION: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 positions may result in severe engine damage.
NOTE:Make sure the camshaft bearing caps are marked as instructed in the previous step.






50. Verify the RH camshafts are in the neutral position.

CAUTION:The camshafts must be in the neutral position before removing the bearing caps or damage to the engine may occur.






51. Remove the 3 bolts and the RH camshaft phaser and sprocket.

CAUTION:Do not allow the camshaft to rotate from the neutral position while removing the camshaft phaser and sprocket or damage to the engine may occur.
NOTE:Install a 3/8-in ratchet and extension into the D-slot on the rear of the intake camshaft to hold the camshaft in place for removal of the camshaft phaser and sprocket bolts.






52. Remove and discard the VCT system oil filter screen from the RH camshaft.






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

CAUTION: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 positions may result in severe engine damage.






54. Loosen the bolts evenly in the sequence shown.
a. Remove the camshaft bearing thrust caps (5R and 1R).

b. Remove the remaining camshaft bearing caps.

c. Remove the camshafts from the cylinder head.

CAUTION: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.






55. Remove the LH and RH camshaft roller followers.

- Mark the location of the roller followers, using a permanent-type marker.

CAUTION: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.






56. Remove the hydraulic lash adjusters.

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






57. Loosen the bolts in the indicated sequence and remove the LH and RH cylinder heads.

- Discard the bolts and the gaskets.

NOTE:RH shown, LH similar.






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






59. Remove the bolts and the oil separator cover.

- Discard the gasket.






60. Remove the crankshaft key.
