CYLINDER HEAD GASKET (for Bank 2) INSTALLATION


  1. INSPECT CYLINDER HEAD SET BOLT


    1. A01GL8RE07

      Using a vernier caliper, measure the minimum diameter of the elongated thread at the measuring point.

      Standard outside diameter
      10.85 to 11.00 mm (0.427 to 0.433 in.)
      Minimum outside diameter
      10.6 mm (0.417 in.)
      Measuring point
      90 mm (3.573 in.) for intake side bolt
      85 mm (3.376 in.) for exhaust side bolt

      Tech Tips


      • If a visual check reveals no excessively thin areas, check the center of the bolt (see illustration) and find the area that has the lowest diameter.

      • If the diameter is less than the minimum, replace the cylinder head bolt.

  2. INSPECT CYLINDER HEAD SUB-ASSEMBLY


    1. A01GNBBE02

      Using a precision straightedge and feeler gauge, measure the warpage of the contact surfaces of the cylinder block and manifold.

      Standard warpage
      Item Specified Condition
      Cylinder head lower side 0.05 mm (0.0020 in.)
      Intake side 0.08 mm (0.0031 in.)
      Exhaust side 0.05 mm (0.0020 in.)
      Maximum warpage
      0.10 mm (0.0039 in.)

      If the warpage is greater than the maximum, replace the cylinder head.

    2. A01GLKS

      Using a dye penetrant, check the intake ports, exhaust ports and cylinder surface for cracks.

      If cracked, replace the cylinder head.

  3. INSTALL CYLINDER HEAD SUB-ASSEMBLY (for Bank 2)


    1. Check the piston protrusions for each cylinder.


      1. Clean the cylinder block with solvent.

      2. Set the piston of the cylinder to be measured to slightly ATDC.

    2. A01GJYQE01

      Place the cylinder head gasket on the cylinder block surface with the front face of the Lot No. stamp upward.

      Note


      • Be careful of the installation direction.

      • Gently place the cylinder head in order not to damage the gasket with the bottom part of the head.

    3. Place the cylinder head on the cylinder block.

      Note

      Ensure that no oil is on the mounting surface of the cylinder head.

      Tech Tips

      The cylinder head bolts are tightened in 3 progressive steps.

    4. Apply a light coat of engine oil to the threads and under the heads of the cylinder head bolts.

    5. A01GJN2E02

      Step 1:


      1. Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 10 cylinder head bolts with the plate washers in several steps, in the sequence shown in the illustration.

        Torque:
        36 N*m  { 367 kgf*cm, 27 ft.*lbf }
    6. A01GHYSE01

      Step 2:


      1. Mark the cylinder head bolt head with paint as shown in the illustration.

      2. Tighten the cylinder head bolts another 90° in the sequence shown in step 1.

    7. Step 3:


      1. Tighten the cylinder head bolts by an additional 90° in the sequence shown in step 1.

      2. Check that the painting marks are now facing rearward.

    8. A01GL5KE02

      Uniformly install the 2 cylinder head bolts.

      Torque:
      21 N*m  { 214 kgf*cm, 15 ft.*lbf }

  4. INSTALL VALVE STEM CAP


    1. Apply a light coat of engine oil to the valve stem caps.

    2. Install the 16 valve stem caps to the cylinder head.

  5. INSTALL VALVE LASH ADJUSTER ASSEMBLY


    1. Be sure to inspect the valve lash adjuster before installing it Click here.

    2. Install the 16 valve lash adjusters to the cylinder head.

      Note

      Install the lash adjuster at the same place it was removed from.

  6. INSTALL NO. 1 VALVE ROCKER ARM SUB-ASSEMBLY


    1. Apply engine oil to the lash adjuster tips and valve stem cap ends.

    2. A01GK51E03

      Make sure that the valve rocker arms are installed as shown in the illustration.

  7. INSTALL CAMSHAFT (for Bank 2)
