(3) Apply Mopar GEN II Silicone Rubber Adhe-
sive Sealant, or equivalent, to the four corner joints.
An excessive amount of sealant is not required to

amount of sealant may reduce the effectiveness of
the flange gasket and cross—over gaskets (Fig. 68).
The sealant should be approximately 5 mm (0.2 in)
in diameter.
(4) Install the front and rear cross-over gaskets.
