Exhaust Manifolds
The exhaust manifolds are one piece fabricated stainless steel and are a double
wall design. The exhaust
manifolds direct exhaust gases from the combustion chambers to the exhaust system. Each manifold has
a single inlet for the Air
Injection Reaction (AIR) system and a threaded opening for oxygen sensor
installation.
Intake Manifold
The
IAFM or integrated air fuel module
is
a one piece composite design that incorporates metal threaded
inserts for mounting the fuel rail and throttle body. The intake manifold
is
sealed to the cylinder heads by
eight separate nonreusable silicone sealing gaskets which press into the grooves
of
the intake housing.
The drive by wire throttle body assembly bolts to the front
of
the intake manifold. The throttle body
is
sealed to the intake manifold by a one piece push
in
place silicone gasket. The fuel rail assembly with
eight separate fuel injectors
is
retained to the intake by four bolts. The injectors are seated
in
their
individual manifold bores with
O-ring seals to provide sealing. A fuel rail stop bracket is retained at the
rear
of
the left fuel rail by the intake manifold mounting bolts. A snap fit Manifold Absolute Pressure
(MAP)
sensor housing
is
mounted at the rear
of
the manifold and sealed by an O-ring seal. The MAP
sensor
is
installed and retained to the MAP sensor housing. There are no coolant passages within the
intake manifold.
Oil Pan
The structural two-piece oil pan assembly has cast aluminum upper and lower halves.
Incorporated into
the
oil pan (upper) design are the oil filter mounting boss, oil level sensor mounting bore, and a non-
removable
oil pan baffle. The
oil
pan cover, oil temperature sensor, and oil level sensor mount to the
sides
of
the oil pan (upper). Incorporated into the oil pan (lower) design are the drain plug opening and
internal oil control ribbing. A nylon carrier (with silicone bead) type gasket provides
sealing between the
upper and lower halves
of
the oil pan assembly. The alignment
of
the structural oil pan assembly to the
rear
of
the engine block and transmission bell housing
is
critical.
Piston and Connecting Rod
Assemblies
The pistons are cast aluminum. The pistons use two compression rings and one oil control ring assembly.
The piston
is
a low friction, lightweight design with a flat top and barrel shaped skirt. The piston pins are
chromium
steel. They have a floating fit
in
the piston and are retained by a press fit
in
the connecting rod.
The connecting rods are powdered
metal. The connecting rods are fractured at the connecting rod journal
and then machined for the proper clearance. The piston, pin, and connecting rod are to be serviced as
an
assembly.
Valve Rocker Arm Cover Assemblies
The
valve rocker arm covers are cast aluminum and use a pre-molded silicone gasket for sealing.
Mounted to each rocker cover
is
an ignition coil and bracket assembly. Incorporated into the covers are
the
oil fill tube, the Positive Crankcase Ventilation (PCV) system passages, and the engine fresh air
passages.
Valve Train
Motion
is
transmitted from the camshaft through the hydraulic roller valve lifters and tubular pushrods to
the
roller type rocker arms. The valve lifter guides position and retain the valve lifters. The valve rocker
arms for each bank
of
cylinders are mounted on pedestals (pivot supports). Each rocker arm
is
retained
on the pivot support and cylinder head by a bolt.
Valve lash
is
net build.
