3. OIL DRAIN LINE
A. To provide an oil drain for the supercharger, it is
necessary to make a hole in the front of the oil
pan. Locate and centerpunch the hole. This hole
should be centered .40” from the bottom of the
oil pan lip between the last bolt and the driver’s
side of the oil pan. (See
Fig. 3-a.)
B. Drill the 1/8” pilot hole at the center location.
C. Use the supplied 9/16” Rotabroach to drill a hole
in oil pan. Break through the pan easily so that
the cut out piece does not go into the oil pan.
D. Tap 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 heavy grease to hold
chips.
E. Thoroughly clean the threaded area. Reach inside
the oil pan and retrieve any stray chips. Apply a
small amount of silicone sealer to the new threads.
Apply more sealer to the 3/8” NPT hex nipple and
secure in the hole. Make sure a seal is formed all
around the fitting. Install elbow and barb fitting
pointing up and towards the side of the alternator
(see
Fig. 3-b) so that the oil drain hose will have
maximum clearance to the damper once installed.
F. Temporarily cover the oil drain barb fitting to keep
out debris.
G. Drain the engine oil, install a new filter and refill
the engine with fresh oil.
