  Tightening procedure

  (1) 3—11 N·m {30.6—112 kgf·cm, 26.6—97.3 in·lbf}
  (2) 13—17 N·m {1.4 —1.7 kgf·m, 9.6—12.5 ft·lbf}
  (3) 43—47 N·m {4.4 —4.7 kgf·m, 31.8—34.6 ft·lbf}
  (4) 88°—92°
  (5) 88°—92°

Camshaft Assembly Note

1. Apply the gear oil (SAE No. 90 or equivalent) to each journal of the cylinder head as shown in the figure.

  Note
  • To prevent engine oil leakage, apply sealant to the rear camshaft cap on the intake side and seal the journal.

  Sealan agent bead width

  1.0 mm {0.039 in}

5. Install the camshaft caps and hand-tighten the camshaft cap bolts evenly in two or three passes, and then tighten the camshaft cap bolts in two passes, in the order shown in the figure.

  Tightening procedure

  (1) 5.0—9.0 N·m {51.0—91.7 kgf·cm, 44.3—79.5 in·lbf}
  (2) 14—17 N·m {1.5—1.7 kgf·m, 10.4—12.5 ft·lbf}

Camshaft Sprocket, Variable Valve Timing Actuator Assembly Note

1. Leave the camshaft sprocket installation bolt temporarily tightened until the timing chain is installed. After the timing chain is installed, tighten it to the specified torque.
