MANIFOLD - INTAKE
DESCRIPTION
The intake manifold is made of a composite material and features long runners which maximizes low end torque.
The intake manifold uses single plane sealing which consist of eight individual press in place port gaskets to prevent
leaks. Eight studs and two bolts are used to fasten the intake to the head.
DIAGNOSIS AND TESTING - INTAKE MANIFOLD LEAKAGE
An intake manifold air leak is characterized by lower than normal manifoldvacuum. Also, one or more cylinders may
not be functioning.

MANIFOLD - EXHAUST
DESCRIPTION
The exhaust manifolds are log style with a patented flow enhancing design to maximize performance. The exhaust
manifolds are made of high silicon molybdenum cast iron. A perforated coregraphite exhaust manifold gasket is
used to improve sealing to the cylinder head. The exhaust manifolds are covered by a three layer laminated heat
shield for thermal protection and noise reduction. The heat shields are fastened with a torque prevailing nut that is
backed off slightly to allow for the thermal expansion of the exhaust manifold.

rubbing alcohol.
CAUTION: The 4.7L can use a special RTV sealer
instead of a carrier gasket to seal the timing cover
to the engine block, from the factory. For service
repairs, Mopar
Grey Engine RTV must be used as
a substitute, if RTV is present. If the front cover
being used has no provisions for the water pas-
sage o-rings, then Mopar
Grey Engine RTV must
be applied around the water passages.
