INSPECTION

1. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY LH

(a) Using a precision straightedge and feeler gauge, measure the warpage on the contact surface of the cylinder head.
Maximum warpage:
0.7 mm (0.028 in.)
HINT: The maximum allowable warpage of each installation surface is 0.3 mm (0.012 in.).
If the warpage is greater than the maximum, replace the manifold.
2. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY RH

(a) Using a precision straightedge and feeler gauge, measure the warpage on the contact surface of the intake manifold.
Maximum warpage:
2.5 mm (0.098 in.)
If the warpage is greater than the maximum, replace the surge tank.
4. INSPECT INTAKE MANIFOLD

(a) Cylinder head side:
(1) Using a precision straightedge and feeler gauge, measure the surface contacting the cylinder head for warpage.
Maximum warpage:
0.1 mm (0.003 in.)
If the warpage is greater than the maximum, replace the intake manifold.
(b) Surge tank side:
(1) Using a precision straightedge and feeler gauge, measure the surface contacting the surge tank for warpage.
Maximum warpage:
0.1 mm (0.003 in.)
If the warpage is greater than the maximum, replace the intake manifold.
