CYLINDER HEAD GASKET INSTALLATION

CAUTION / NOTICE / HINT

Note:

  • Always be sure to check the tightening torque.

  • If the pressure lines are leaking after installation, they must be replaced.

  • Do not overtighten the pressure lines.

PROCEDURE

  1. SELECT CYLINDER HEAD GASKET

    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 before TDC.

        Protrusion

        Using SST, place a dial indicator on the cylinder block and set the measuring tip as shown in the illustration.

        SST

        PZ4TB-04901-85

      4. Set the dial indicator at 0 mm (0 in.).

        Tip:

        Make sure that the measuring tip is perpendicular to the cylinder head gasket surface and piston head when taking the measurements.

      5. Find where the piston head protrudes most by slowly turning the crankshaft clockwise and counterclockwise.

      6. Measure each cylinder at 2 places for a total of 8 measurements.

      7. For the piston protrusion value of each cylinder, use the average of the 2 measurements of each cylinder.

        Standard piston protrusion

        0.920 to 1.180 mm (0.0362 to 0.0465 in.)

        If the protrusion is not as specified, remove the piston sub-assembly and connecting rod sub-assembly and reinstall them.

      Piston Protrusion

      0.92 mm (0.0362 in.) or less

      0.92 to 1.03 mm (0.0362 to 0.0406 in.)

      1.03 to 1.18 mm (0.0406 to 0.0465 in.)

      Cylinder Head Gasket Holes

      1 Hole

      2 Holes

      3 Holes
      Tip:

      Cylinder head gaskets have 1, 2 or 3 holes.

  2. INSTALL CYLINDER HEAD GASKET

    1. Place a new cylinder head gasket in position on the cylinder block.

  3. INSTALL CYLINDER HEAD SUB-ASSEMBLY

    Note:

    • Do not reuse the cylinder head bolts.

      Make sure the ring pins shown in the illustration are not loose, deformed or otherwise damaged.

    1. Place the cylinder head sub-assembly on the cylinder head gasket.

      Note:

      Be careful of the installation direction.

    2. A318383

      Using an E10 "TORX" socket wrench, temporarily install the 5 bolts.

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

      Note:

      Do not reuse the cylinder head bolts.

    4. Temporarily install the cylinder head bolts.
