INSPECT INTAKE MANIFOLD
Cylinder head side:
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. |
Surge tank side:
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. |
