INSPECT NO. 1 VALVE ROCKER ARM SUB-ASSEMBLY

1. Turn the roller by hand to check that it turns smoothly.

   

   If the roller does not turn smoothly, replace the No. 1 valve rocker arm sub-assembly.

INSPECT VALVE LASH ADJUSTER ASSEMBLY

1. Place the lash adjuster into a container full of new engine oil.

2. Insert the tip of SST into the lash adjuster plunger and use the tip to press down on the check ball inside the plunger.

   

   SST

   09276-75010

3. Squeeze SST and the valve lash adjuster together to move the plunger up and down 5 to 6 times.

4. Check the movement of the plunger and bleed the air.

   OK
   Plunger moves up and down.

   Note

   When bleeding high-pressure air from the compression chamber, make sure that the tip of SST is actually pressing the check ball as shown in the illustration. If the check ball is not pressed, air bleeding is not possible.

5. After bleeding the air, remove SST. Then try to quickly and firmly press the plunger with your fingers.

   OK
   Plunger can be pressed 3 times.

   If the plunger can still be compressed after pressing it 3 times, replace the valve lash adjuster with a new one.

INSPECT CYLINDER HEAD BOLT

1. Using a vernier caliper, measure the length of the cylinder head bolt from the seat to the end.

   

   Standard length
   146.8 to 148.2 mm (5.78 to 5.83 in.)

   Maximum length
   149.2 mm (5.87 in.)

   If the length is more than the maximum, replace the cylinder head bolt.

2. Using a vernier caliper, measure the diameter of the elongated thread at the measuring area.

   Distance
   115 mm (4.53 in.)

   Standard diameter
   9.77 to 9.96 mm (0.385 to 0.392 in.)

   Minimum diameter
   9.4 mm (0.370 in.)

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

   Tech Tips

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

INSPECT CYLINDER HEAD

1. Using a precision straightedge and feeler gauge, measure the warpage of the contact surfaces where the cylinder head contacts the cylinder block and manifolds.

   

   Maximum Warpage
   Item Specified Condition Cylinder block side 0.05 mm (0.00197 in.) Intake manifold side 0.10 mm (0.00394 in.) Exhaust manifold side 0.10 mm (0.00394 in.)

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

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.
