A. Raise the front of the ve-
hicle and support with ap-
propriate jack stands.
B. To provide an oil drain for
the supercharger, it is nec-
essary to make a hole in the
oil pan. It is best to punch
the hole rather than drill.
Remove paint around the
hole area so that it does not
flake into the pan.
C. Make a mark on the oil pan
on the driver’s side ahead
of the oil filter. The mark
should be 3" below the third
bolt from the rear of the pan.
D. Use a small center punch to perforate the pan
and expand the hole. Switch to a larger diameter
punch and expand the hole further to approxi-
mately 9/16" diameter. Most punches are made
from hexagon material and may be placed in a
socket with an extension to make this procedure
easier.
E. Tap the hole with a 3/8" NPT tap approximately
1/4" deep. Pack the flutes of the tap with heavy
grease to catch and hold the chips. Once the tap
is removed, it must be cleaned and repacked
before tapping is resumed. Use a small magnet
to check for any stray chips after tapping proce-
dure.
F. Thoroughly clean the threaded area with ac-
etone or other solvent. Apply a small amount of
silicone sealer to the new threads. Apply more
sealer to the threads of the 3/8" NPT 90
°
fitting
and secure it in the hole with the hose fitting
pointing forward and slightly upward. Make
sure a seal is formed all around the fitting at the
pan.
G. Route the line forward along the top rail of the oil
pan and secure to pan bolts with the clamps
provided. Temporarily cover end of hose and
secure out of the way.
H. Drain and replace engine oil and change filter.
NOTE: This method of rolling over the lip of
the hole and tapping it works well if
CAREFULLY done and should cause
no problems.
