(6) Install the flange gaskets. Ensure that the ver
tical port alignment tab is resting on the deck face of
the block. Also the horizontal alignment tabs must be
in position with the mating cylinder head gasket tabs
(Fig. 4). The words MANIFOLD SIDE should be vis
ible on the center of each flange gasket.
(7) Carefully lower intake manifold into position on
the cylinder block and cylinder heads. Use the align
ment dowels in the cross-over gaskets to position the
intake manifold. After intake manifold is in place, in
spect to make sure seals are in place.
(8) Install the intake manifold bolts and tighten as
follows:
¥-6 ENGINE—(Fig. 5)
• Step 1-Tighten bolts 1 and 2 to 8 N-m (72 in. lbs.)
torque. Tighten in alternating steps 1.4 N-m (12 in.
lbs.) torque at a time.
• Step 2—Tighten bolts 3 through 12, in sequence,
to 8 N-m (72 in. lbs.) torque.
• Step 3—Check that all bolts are tighten to 8 N-m
(72 in. lbs.) torque.
• Step 4—Tighten all bolts, in sequence, to 16 N-m
(12 ft. lbs.) torque.
• Step 5—Check that all bolts are tighten to 16 N-m
(12 ft. lbs.) torque.
