Drain the engine oil.

Remove the steel oil pan (optional).

To provide an oil drain for the supercharger, it is nec-

essary to make a hole in the driver’s side of the alu-

minum 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 sup-

plied 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 restrict-

ed 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 seal-

er 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 surfaces, apply a .2"

(5mm) wide bead of silicone 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.

NOTE: It is recommended that the lower oil pan

be removed so that any chips from the

following precedure can be cleaned up.

To do this, a seal cutter and silicone RTV

(Permatex ultra grey: 82194 or equiva-

lent) are required.
