      Tech Tips

      Apply at least 20 mm (0.787 in.) of seal packing from the inside edge of the protrusion of the cylinder block.

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

      Note

      Pay attention to the installation direction.

  2. INSTALL CYLINDER HEAD SUB-ASSEMBLY

    Tech Tips

    Perform "Inspection After Repairs" after replacing the cylinder head sub-assembly.



    1. Place the cylinder head on the cylinder block.

      Note


      • Make sure that no oil is on the mounting surface of the cylinder head.

      • Place the cylinder head on the cylinder block gently in order not to damage the gasket with the bottom part of the head.

      Tech Tips

      The cylinder head bolts are tightened in 4 progressive steps.

    2. Install the plate washers to the cylinder head bolts.

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

    4. Step 1:


      1. A01QSKWN03

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

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

        Note

        Do not drop the plate washer for the cylinder head bolt into the cylinder head.

    5. Step 2:


      1. Tighten the cylinder head bolts again in the sequence shown in the illustration to make sure that they are tightened to the specified torque.

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

    6. Step 3:


      1. Mark the front side of each cylinder head bolt head with paint.

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

    7. Step 4:


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

      2. Check that the paint marks are now at a 180° angle to the front.

        Note


        • Do not apply oil for at least 4 hours after the installation.

        • Do not start the engine for at least 4 hours after installation.

        • After installation, if the seal packing has seeped out, wipe it off.

  3. INSTALL VALVE STEM CAP


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

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

      Note

      Do not drop the valve stem caps into the cylinder head.

  4. SET CAMSHAFT TIMING GEAR ASSEMBLY

    Tech Tips


    • When reusing the camshaft timing gear, release the lock pin and set the camshaft timing gear to the advanced position before installation.

    • If the camshaft timing gear is new or has already been set to the advanced position, install the camshaft timing gear after the camshafts have been installed to the engine.


    1. A01QUACC07
      *1 Knock Pin Hole
      *2 Alignment Mark
      *a Advanced Position
      *b Retarded Position

      Check the camshaft timing gear position.

      Note

      If the camshaft timing gear is set to the advanced position, do not let the camshaft timing gear rotate clockwise during installation.

      If the camshaft timing gear rotates to the retarded position, release the lock pin and set the camshaft timing gear to the advanced position.

    2. A01QQN6C25
      *1 Pin Hole
      *2 Knock Pin

      Align the knock pin of the camshaft with the pin hole of the camshaft timing gear and attach the gear to the camshaft.

    3. A01QQYCC39
      *1 Camshaft Timing Gear
      *2 Clearance
      *3 Camshaft Flange
      *a INCORRECT
      *b CORRECT

      Check that there is no clearance between the camshaft timing gear and camshaft flange.

    4. Fix the camshaft in place by hand, and then install the installation bolt of the camshaft timing gear by hand.

      Note

      Do not use any tools to install the bolt. If the bolt is installed using a tool, the lock pin will be damaged.

    5. Release the lock pin.


      1. Clean the camshaft journal with non-residue solvent.

      2. Cover the 4 oil paths of the cam journal with vinyl tape as shown in the illustration.

        *1 Retard Side Path *2 Advance Side Path
        *3 Port A *4 Knock Pin
        *a Open *b Closed
        A01QTWQ Rubber A01QU7U Vinyl Tape

      3. Open a hole at port A shown in the illustration.

      4. A01QQT1

        While applying compressed air at approximately 200 kPa (2.0 kgf/ cm2, 29 psi) to the oil path, forcibly turn the camshaft timing gear assembly in the advance direction (counterclockwise).

        CAUTION:

        Cover the paths with a piece of cloth when applying pressure to keep oil from splashing.

        Note

        Do not allow the camshaft timing gear assembly to lock. If it locks, release the lock pin again.

        Tech Tips


        • The camshaft timing gear assembly may be turned in the advance direction without applying any force.

        • If enough air pressure cannot be applied because of air leakage from the port, releasing the lock pin may be difficult.

      5. Remove the vinyl tape and pieces of rubber from the camshaft.

    6. Remove the bolt and camshaft timing gear.

      Note

      Do not allow the camshaft timing gear assembly to lock. If it locks, release the lock pin again.
