96775 v.2.0

This manifold installation procedure

assumes that the cylinder heads are

assembled with all port and valve

work completed, and are installed and

torqued, ready for manifold installation.

Because of the custom nature of this

application, the installer should test fit

all components and related systems

prior to performing a final assembly of

the intake manifolding. If the original

coolant outlet/thermostat housing “Y”

casting is to be retained, modifications

to this casting and the thermostat

cover will need to be considered to

clear the manifold castings.
Once the manifold castings are bolted

in place, it becomes somewhat difficult

to access and make system connec-

tions under the plenums in the valley

area. Preplan your work and make as

many of your required system con-

nections in the valley before installing

the manifold halves. Pre-assemble and

install any fuel and oil hoses that tie

outside components to the valley area.
The fuel injection pump should be

installed along with inlet and return

adapter fittings in the pump ports.

Injectors should be installed in the

cylinder heads.
Install a turbocharger oil supply adapter

fitting (not supplied) in the boss in the

engine valley along with any related

plumbing (hose with divider “T” and

branch lines to provide oil to the

turbochargers) as this area becomes

inaccessible once the manifolds are

installed. Fitting or hose end used for

oil supply should be a 90° elbow style

to point forward to clear fuel return

cluster panel.
