Intake Manifold Seals

- Turn manifold assembly upside down and install four new seals into mating grooves,

positioning each seal so that the section which connects the seals is on the outer edge of

the manifold. PITA Alert! During installation of the manifold these seals may fall out of their

grooves. Be sure they are correctly seated prior to final positioning of manifold.

At this point we’re ready to reinstall the intake manifold. Reinspect all work completed thus far, as

a final check. Pay attention to the engine block and sealing surfaces, and make sure all wiring

harnesses are positioned out of the way.

INTAKE MANIFOLD INSTALLATION

- Remove paper towels from intake ports in heads.

- Move driver’s side engine harness toward back of engine compartment, resting on

valve cover and firewall. Move passenger side harness as far rearward as possible.

Ensure knock sensor harnesses run forward along the bottom of the valley, draping

over front of engine block.

- Position intake manifold assembly onto motor, as far back as possible (A) until

interference with engine harnesses is encountered. Note in this photo how one of

the intake seals has dropped down out of its mounting groove.

- Now reposition driver’s side harness to the front of compartment, "folding" it back

forward. Reposition driver’s harness forward as much as possible.

- Now carefully work intake manifold rearward until you can lay it down over

mounting studs.

- Once the manifold is located on the mounting studs, use a suitable lever (B) (eg.,

ratchet wrench handle) to wedge the manifold up off the engine. Carefully ensure

all intake manifold seals are correctly positioned in their grooves. Do this
