1) Release fuel pressure. See FUEL PRESSURE RELEASE.
Disconnect negative battery cable. Drain cooling system. Disconnect
accelerator, cruise control, and transmission kickdown cables.
Disconnect fuel lines at throttle body. See FUEL LINE DISCONNECT
FITTINGS.
2) Remove engine cover (Ram Van/Wagon), air cleaner and
generator. Disconnect necessary electrical wiring, coolant hoses and
vacuum hoses. Remove distributor cap and spark plug wires. Remove
valve covers (if necessary).
3) Remove bolts, intake manifold and gaskets. Separate
throttle body from intake manifold (if necessary). Turn intake
manifold upside-down and remove plenum pan (if necessary).

Installation
1) Install plenum pan and install all bolts finger tight.

and camshaft. To install remaining components, reverse removal
procedure.

ROCKER ARMS
Removal
Disconnect spark plug wires, PCV and fuel evaporation hoses.
Remove valve covers. Remove bolts, pivots, and rocker arms. Wire
components together for installation reference. Mark each push rod for
location, and remove (if necessary).
CAUTION: To avoid piston-to-valve contact during rocker arm
installation, crankshaft must be placed in specified
position. Wait 5 minutes before starting engine to allow
valve lifters to bleed down after rocker arm installation.
Installation
1) On 3.9L engine, locate "V6" mark stamped on vibration
damper (147 degrees ATDC). Rotate engine by hand until "V6" mark lines\
up with TDC mark on timing chain cover.
2) On 5.2L and 5.9L engines, locate "V8" mark stamped on
vibration damper (147 degrees ATDC). Rotate engine by hand until "V8"
mark lines up with TDC mark on timing chain cover.
3) Install rocker arm and pivot assemblies and tighten bolt
to 21 ft. lbs. (28 N.m). Wait 5 minutes before starting engine to
allow valve lifters to bleed down after rocker arm installation. To
install remaining components, reverse removal procedure. Tighten valve
cover bolts to 95 INCH lbs. (11 N.m).

Engine pre-oiling can be done using pressure oiler (if
available). Connect pressure oiler to cylinder block oil passage
such as oil pressure sending unit. Operate pressure oiler long enough
to ensure correct amount of oil has filled crankcase. Check oil level
while pre-oiling.
If pressure oiler is not available, disconnect ignition
system. Remove oil pressure sending unit and replace with oil pressure
test gauge. Using starter motor, rotate engine starter until gauge
shows normal oil pressure for several seconds. DO NOT crank engine
for more than 30 seconds to avoid starter motor damage.
Ensure oil pressure has reached the most distant point from
the oil pump. Reinstall oil pressure sending unit. Reconnect ignition
system.
INITIAL START-UP
Start the engine and operate engine at low speed while
checking for coolant, fuel and oil leaks. Stop engine. Recheck coolant
and oil level. Adjust if necessary.
CAMSHAFT
Break-in procedure is required when a new or reground
camshaft has been installed. Operate and maintain engine speed between
1500-2500 RPM for approximately 30 minutes. Procedure may vary due to
manufacturers recommendations.
PISTON RINGS
Piston rings require a break-in procedure to ensure seating
of rings to cylinder walls. Serious damage may occur to rings if
correct procedures are not followed.
Extremely high piston ring temperatures are produced obtained
during break-in process. If rings are exposed to excessively high RPM
or high cylinder pressures, ring damage can occur. Follow piston ring
manufacturer's recommended break-in procedure.
FINAL ADJUSTMENTS
Check or adjust ignition timing and dwell (if applicable).
Adjust valves (if necessary). Adjust carburetion or injection idle
speed and mixture. Retighten cylinder heads (if required). If
cylinder head or block is aluminum, retighten bolts when engine is
cold. Follow the engine manufacturer's recommended break-in procedure
and maintenance schedule for new engines.
NOTE: Some manufacturer's require that head bolts be retightened
after specified amount of operation. This must be done to
prevent head gasket failure.
