Intake Manifold: Testing and Inspection

INSPECT AIR INTAKE CHAMBER






Using a precision straight edge and feeler gauge, measure the surfaces contacting the intake manifold for warpage.
Maximum warpage: 0.15 mm (0.0059 inch).
If warpage is greater than maximum, replace the chamber.

INSPECT INTAKE MANIFOLD






Using a precision straight edge and feeler gauge, measure the surfaces contacting the cylinder head and air intake chamber for warpage.
Maximum warpage: 0.15 mm (0.0059 inch).
If warpage is greater than maximum, replace the manifold.
