1. Inspect the circle runout.
   
   

   1. Place the camshaft on V-blocks.
      

   2. Using a dial indicator, measure the circle runout at the center journal.
      

      Maximum circle runout:

      0.10 mm (0.00394 in.)
      

      If the circle runout is more than the maximum, replace the camshaft.
      

2. Using a micrometer, measure the cam lobe height.
   

   Standard Cam Lobe Height:

   Cam Lobe	Specified Condition
   Intake	54.890 to 54.910 mm (2.1610 to 2.1618 in.)
   Exhaust	54.990 to 55.010 mm (2.1650 to 2.1657 in.)

   Minimum Cam Lobe Height:

   cam Lobe	Specified Condition
   Intake	54.39 mm (2.141 in.)
   Exhaust	54.49 mm (2.145 in.)

   If the cam lobe height is less than the minimum, replace the camshaft.
   

1. Using a precision straightedge and feeler gauge, measure the surface that contact the cylinder head for warpage.
   

   Maximum warpage:

   0.40 mm (0.0157 in.)
   

   If the warpage is more than the maximum, replace the intake manifold.
   

1. Using a precision straightedge and feeler gauge, measure the surface that contact the cylinder head for warpage.
   

   Maximum warpage:

   0.40 mm (0.0157 in.)
   

   If the warpage is more than the maximum, replace the exhaust manifold.
   

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

   Standard outer diameter:

   11.80 to 12.00 mm (0.465 to 0.472 in.)
   

   Minimum outer diameter:

   11.60 mm (0.457 in.)
