4. OIL RETURN FITTING
A. Remove the passenger side valve cover.
B. Drill a 9/16" hole in the front of the valve cover.
Make sure that the hole is drilled in the flat area
on the end of the valve cover. (See
Fig. 4-a.) On
some later model trucks, the valve covers are
slightly different and may require different place-
ment of the drain hole.
C. Tap the 9/16" hole using a 3/8" NPT pipe tap.
D. Install the supplied 90
°
elbow and hose fitting
into the valve cover. The fittings should run
almost horizontally pointing inward as shown in
Fig. 6-b on page 2.
E. Thoroughly clean the valve cover and gasket of
any chips and reinstall the valve cover.
NOTE: It is necessary to unfasten the brack-
ets holding the air tubes running from
the smog pump over the valve cover
so that they may be pushed aside.
