NOTE: If converter has failed, always check muffler to
be sure converter debris has not entered muffler.
(8) Stop engine.
(9) Disconnect tachometer and vacuum gauge.
(10) On six-cylinder engines, remove exhaust mani-
fold. On eight-cylinder engines, remove both exhaust
manifolds.
(11) Inspect ports of exhaust manifold for casting
flash by dropping length of chain into each port.
N O T E : Do not use a wire or a light to check ports. The
restricted opening may be large enough for them to pass
through but small enough to cause excessive back pres-
sure at high engine rpm.
(12) Remove casting flash. If flash is at lower end of
port, it can usually be chipped out. If flash cannot be
removed, replace manifold.
(13) Install exhaust manifold(s).
