Lubrication System
This repair group covers lubrication system troubleshooting
as well as oil pan removal and oil pump replacement.
In 6-cylinder models, removal of the oil pan requires the re-
moval of the exhaust system and some front suspension
components. Those procedures are fully covered in:
180 Exhaust System
210 Clutch
230 Manual Transmission
0 240 Automatic Transmission
310 Front Suspension
320 Steering and Wheel Alignment
NOTE-
Oil change procedure and oil filter replacement are covered
in
020 Maintenance.
CAUTIOG
V8 engines: The oil pump fasteners (including the sprocket
retaining nut) are known to vibrate loose. This can result in oil
starvation and engine failure. Be sure to check oil bolts and
nut tightness whenever the
oilpump is accessible. If any fas-
teners are found to be loose, remove them and reinstall with
Loctite
Band torque to specifications.
Special tools
The engine needs to be properly supported while the front
suspension
subframe is lowered to access the oil pan.
A standard oil pressure gauge may be used for measuring oil
pressure.

Engine lubrication
Oil pressure is generated by a gear-type pump bolted to the
bottom oi the engine block. The oil pump is chain driven off
the front of the crankshaft.
Table a. Engine oil capacity (includes oil filter replacement)
6-cylinder 6.5
liters (6.9
US qt)
V-8 7.5 liters (7.9 US qt)
The oil pressure warning system consists of an oil pressure
switch mounted in the oil circuit and an instrument
panel
warning light. Other saiety features include:
Q A filter bypass to provide lubrication should the oil filter be-
come clogged.
An oil pump pressure relief valve to prevent excessive sys-
tem pressure.
CAUTIOI\C
If the red oil pressure warning light comes on or flashes on
while driving, always assume that the oilpressure is low. Stop
the engine immediately and make arrangements to test oil
pressure.

Lubrication System
To test switch, connect an ohmmeter between terminal in
switch body (arrow) and ground. With engine off, there
should be continuity. With engine running, oil pressure
should open switch and there should be no continuity. Re-
place a faulty switch.
CAUTION-
Keep in mind that low oil pressure may be preventing the
switch from turning the light out
If the light remains on while
the engine is running, check the oil pressure as described
earlier. Do not drive the car until the problem is corrected. The
engine may be severely damaged.
Crankshaft rear main seal replacement requires removal of
the transmission and flywheel.

Remove remaining seal carrier bolts (arrows) and carefully
remove seal carrier without damaging the oil pan
gasltet.
CAUTION-
After removing seal carrier, checlc oilpan gasket for damage.
If gasket is damaged during removal, remove oil pan (as de-
scribed later) and replace
gasket.
< Remove old seal and install new seal into seal carrier using
BMW special tools
11 1 260 and 00 5 500.
NOTE-
A new radial seal is used from 4/98 production, and is the
only version available from
BMW as a replacement. The
new
sealno longer uses a spring to support the sealing lip.
Do not
lcinlc or damage the sealing lip. Do not touch with
fingers.
* BMW offers the rear main seal carrier and seal in a lit A
plastic support bushing, required for sliding the seal over
the crankshaft, is included with the
lcit.
I CAUTION- 1
Do not use BMW special tool 1 I 2 213 (mstallation guide)
with the new style seal. Use only the special tool
supphed
with the seal lcit.
When reinstalling seal carrier to crankcase:
Check locating sleeves for damage.
Replace
gasltet between rear main seal carrier and crank-
case.
Apply thin coat of
3 Bond 8 1209 or equivalent sealant to
oil pan gasket sealing surfaces.
* Lubricate crankshaft seal contact surface.
Use plastic support bushing
(A) that comes with seal ltit as
an installation
quide, fittina seal over end of crankshaft. Use - -
care to push seal carrier and support bushing on straight,
without tilting sideways. Remove support bushing.
- lnstall seal carrier bolts and torque to specifications.
4 Use new bolts (arrows) at base of seal carrier. Coat threads
with sealing compound before installing.
- Install and tighten oil pan bolts.
