A. Remove the two vacuum lines on the EGR

reference module and mark their position for
reinstallation. Remove module and bracket.

Bend the mount down lengthwise so that the
module will run perpendicular to the ground to
accommodate the discharge tube. (See 

Fig.

.)

C. Remove the EGR tube coming from the ex-

haust. Disconnect the EGR guard, vacuum line
and electrical connector. Remove the EGR valve
and assembly and set aside for reinstallation
later. Remove the guard/bracket. Cut off and
discard the upper portion of the bracket in the
area shown in 

Fig 3-b

.

D. Remove the breather line connecting the intake

to the vapor canister (located on the left fender
apron) for clearance. Remove three left side
spark plug wires from the spark plugs and the
PCV valve and line for access to the left valve
cover.

E. Remove the EGR tube from the exhaust mani-

fold.

F. Remove the left valve cover using care to save

the gasket.

G. An 11/16" hole must be punched or drilled.

Measure and mark the hole location following
the graphic on the next page.

H. Make an 11/16" diameter hole at the mark using

a drill or chassis punch. Deburr the hole com-
pletely. Thoroughly clean the valve cover. (See

Fig. 3-c

.)

I. Install the 1/2" hose fitting into the 3/8" NPT x 45

°

elbow and tighten.

J. Insert the elbow fitting through the hole in the

valve cover so the barb points forward and
slightly up from horizontal. Secure with the
sealing nut provided in the kit. Make sure to
place the sealing side of the nut against the
valve cover surface.

K. Reinstall the valve cover. (See 

Fig. 3-d

.)

L. Install the 1/2" oil drain hose piece and #8

clamps to drain fitting on valve cover.
