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 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.
