1. INSPECT INTAKE MANIFOLD

1. Using a precision straightedge and feeler gauge, measure the warpage of the contact surface of the cylinder head and intake air surge tank.

   Intake manifold side maximum warpage:
     0.8 mm (0.031 in.)
     Cylinder head side maximum warpage:
     0.2 mm (0.008 in.)
   If the warpage is greater than the maximum, replace the intake manifold.

2. INSPECT EXHAUST MANIFOLD

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

   Maximum warpage:
     0.7 mm (0.028 in.)
   If the warpage is greater than the maximum, replace the exhaust manifold.

   HINT:
     Maximum warpage of each installation surface:
     0.3 mm (0.012 in.)
