INSPECTION





1. INSPECT INTAKE AIR SURGE TANK
(a) Using a precision straight edge and feeler gauge, measure the surface contacting the cylinder head for warpage.
Maximum warpage: 0.10 mm (0.0039 inch)
If the warpage is greater than the maximum, replace the manifold.





2. INSPECT INTAKE MANIFOLD
(a) Using a precision straight edge and feeler gauge, measure the surface contacting the cylinder head and air intake surge tank for warpage.

Maximum Warpage:





If warpage is greater than the maximum, replace the manifold.





3. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY RH
(a) Using a precision straight edge and feeler gauge, measure the surface contacting the cylinder head for warpage.
Maximum warpage: 0.50 mm (0.0196 inch)
If the warpage is greater than the maximum, replace the manifold.





4. INSPECT EXHAUST MANIFOLD CONVERTER SUB-ASSEMBLY NO.2
(a) Using a precision straight edge and feeler gauge, measure the surface contacting the cylinder head for warpage.
Maximum warpage: 0.50 mm (0.0196 inch)
If the warpage is greater than the maximum, replace the manifold.
