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.
3. INSPECT INTAKE AIR SURGE TANK ASSEMBLY
(a) Using a precision straightedge and feeler gauge,
measure the warpage on the contact surface of the

(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.
