each other.
- Secure crankshaft in TDC position with BMW special tool
11 2 300.
4 Place BMW special tool 11 3 240 over camshaft ends and
measure clearance of tool to cylinder head surface.
NOTE-
* If the exhaust side of the tool is not flush with the head (gap
A), retime the camshafts as described laler in this repair
group.
Due to flexible sprocket design and VANOS control unit tol-
erances and play, the
intake side of special tool 71 3 240
may be up to
I mm (0.04 in) above the suriace of the cyl-
inder head (gap
B). This is normal. Otherwise, retime the
camshafts as described in
VANOS timing, checking and
adjusting (M52 TU and 11154 engines).

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.

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.
