Drain the engine oil.

Remove the steel oil pan (optional).

To provide an oil drain for the supercharger, it
is necessary to make a hole in the driver’s
side of the aluminum upper oil pan. Find the
proper location and center-punch the hole.
(See Fig. 2-a.)

Access to the oil drain location is restricted
so a low profile or right-angle drill may be
necessary.

Drill a 1/8" hole at the center location. Use
the supplied 9/16" cutter to enlarge the pilot
hole making sure to break through easily (if
the oil pan has not been removed) so that the
cutout does not fall into the pan.

Thread the hole with a 3/8"NPT tap to
approximately 1/2" deep or until the fitting can
be started. Pack the flutes of the tap with
grease to minimize the amount of debris that
gets into the engine. Access is restricted so
inserting the tap in a socket and then using a
ratchet to rotate it is helpful.

Thoroughly clean the threaded area and the
interior of the engine. Apply a small amount
of silicone sealer to the new threads. Apply
more sealer to the 3/8"NPT hose fitting and
secure in the hole. Make sure a seal is
formed all around the fitting.

If necessary, reinstall the oil pan. Clean off
the old sealant and any oil from both sur-
faces, apply a .2" (5mm) wide bead of sili-
cone RTV, install the pan within five minutes
and torque the screws to 74-82 in-lbs (8.3-9.3
N-m) in a rotating sequence.

Wait at least 30 minutes before refilling 
the engine with oil.
