From the B18A Green Book:

Removing the sump

Since it has been found to save work on some
types of engine repairs to be able to remove the
sump without lifting out the engine, the following
method has been worked out.

PV 544-210
REMOVING
1. Lift up the vehicle about 30 cm (12") above
the floor and place blocks under it near the
jacking points.
2. Apply a lifting device under the engine mounti
ngs. N. B. Do not lift on the water pump.
Unscrew the nuts for the front engine mounting
pads from below. Lift the engine as high as
possible without pinching anything on the
scuttle and allow it to hang on pulley blocks, a
workshop hoist, an engine lifter or similar.
3. Place a jack under the front member.
4. Clean off around the brake pipe connections
on the master cylinder. Disconnect the brake
pipes to the front end on the master cylinder.
Plug the lines in order to prevent impurities
from entering the brake system.
5. Remove the four front bolts for the front
member. Screw in two bolts about 75 mm
(2 15/16") long in place of these, one on each
side. Remove the four rear bolts for the
member.
6. Lower the front end so that it is supported in
the two long bolts.
7. Remove the sump in the usual way.

FITTING
1. Fit the sump.
2. Thoroughly clean the front member and lift it
up. Tighten the rear bolts. Remove the long
bolts at the front and fit the ordinary ones.
3. Clean off around the master cylinder and brake
pipes. Fit the brake pipes.
4. Bleed the brakes.
