3. OIL DRAIN

A. To provide an oil drain for the supercharger, it is

necessary to make a hole in the oil pan. Locate
and mark hole as per

Figs. 3-a and 3-b.

B. Carefully drill a pilot hole (the same diameter as

the Rota-Broach pilot) into the marked spot on
the oil pan (this procedure may also be done by
removing the oil pan if you are unsure of your
ability to perform the following steps properly).
Drill slowly as to catch most of the aluminum
chips from the hole being drilled. Using the 9/16"
Roto-Broach, very slowly machine a hole in the
pan (use the previously drilled hole as a guide).
Stop machining just before the tool breaks through
into the oil pan. Using a scribe or a small
screwdriver, remove the remaining disc-shaped
oil pan piece (allowing you to remove the pan slug
before it falls into the oil pan and keeps most of
the aluminum chips out).

C. Tap the hole with a 3/8" NPT tap approximately

1/4" deep. Pack the flutes of the tap with heavy
grease to hold the chips. Thoroughly clean the
threads in the hole with acetone or lacquer thinner.

D. Using a small amount of silicone sealer, install the

3/8 NPT x 45

elbow into the oil pan. Thread the

supplied 3/8" NPT x 1/2" barb fitting into 45

elbow. (Orient the fittings as shown in

Fig. 3-b.)

Temporarily cap the fitting until the drain hose is
connected in Step 7.

E. Drain the engine oil and change the filter. Refill

engine with factory specified weight oil. Vortech
recommends the use of synthetic oil.
