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.

        *b Measuring Point
        *c 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.).

        Tech Tips

        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
        0.420 to 0.680 mm (0.0165 to 0.0267 in.)

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

      Select a new cylinder head gasket.

      New Installed Cylinder Head Gasket Thickness
      Cylinder Head Gasket Holes Specified Condition
      1 Hole 0.95 mm (0.0374 in.)
      2 Holes 1.05 mm (0.0413 in.)
      3 Holes 1.15 mm (0.0452 in.)

      Tech Tips

      Cylinder head gaskets have 1, 2, or 3 holes.


      1. Select the largest piston protrusion value from the measurements and then select a new appropriate gasket according to the table below.

        Cylinder Head Gasket Size
        Item Specified Condition
        Piston Protrusion 0.42 mm (0.0165 in.) or less 0.42 to 0.53 mm (0.0165 to 0.0208 in.) 0.53 to 0.68 mm (0.0208 to 0.0267 in.)

  2. INSTALL CYLINDER HEAD GASKET


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

  3. INSTALL CYLINDER HEAD SUB-ASSEMBLY

    Note


    • Do not reuse the cylinder head bolts.

    • A002NLW

      Make sure the ring pin shown in the illustration is 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. A002PZZ

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

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

      Note

      Do not reuse the cylinder head bolts.

    4. Temporarily install the new cylinder head bolts.

    5. Step 1:


      1. A002Q6PE07

        Using an E18 "TORX" socket wrench, uniformly tighten the 10 cylinder head bolts in several steps in the sequence shown in the illustration.

        Torque:
        70 N*m  { 714 kgf*cm, 52 ft.*lbf }

      2. Mark the front of each cylinder head bolts head with paint.

      3. A002Q6PE06

        Loosen the cylinder head bolts by 180° in the sequence shown in the illustration.

    6. Step 2:


      1. A002Q6PE07

        Tighten the 10 cylinder head bolts in several steps in the sequence shown in the illustration.

        Torque:
        50 N*m  { 510 kgf*cm, 37 ft.*lbf }

      2. Retighten the cylinder head bolts by 120°.

    7. Step 3:


      1. Tighten the cylinder head bolts 120° further.

      2. Check that the paint marks are now at a 240° angle to the RH.

    8. A002PZZ

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

      Torque:
