INSPECT NO. 1 INTAKE MANIFOLD FOR FLATNESS
Using a precision straightedge and feeler gauge, measure the warpage of the contact surface between the No. 1 and No. 3 intake manifold, and the No. 1 intake manifold and cylinder head.
| Maximum Warpage | ||||||
|---|---|---|---|---|---|---|
|
If the warpage is more than the maximum, replace the No. 1 intake manifold.
INSPECT NO. 2 INTAKE MANIFOLD FOR FLATNESS
Using a precision straightedge and feeler gauge, measure the warpage of the contact surface between the No. 2 and No. 3 intake manifold, and the No. 2 intake manifold and cylinder head.
| Maximum Warpage | ||||||
|---|---|---|---|---|---|---|
|
If the warpage is more than the maximum, replace the No. 2 intake manifold.
INSPECT NO. 3 INTAKE MANIFOLD FOR FLATNESS
Using a precision straightedge and feeler gauge, measure the warpage of the contact surface between the No. 3 and No. 1 intake manifold, the No. 3 and No. 2 intake manifold, and the No. 3 intake manifold and intake pipe.
| Maximum Warpage | ||||||
|---|---|---|---|---|---|---|
|
If the warpage is more than the maximum, replace the No. 3 intake manifold.
