Maintenance
NOTE-
The parking brake may lose some of its effectiveness if it is
not used frequently This is due to corrosion build-up on the
parking brake drum. To remove corrosion, apply the parking
brake just until it begins to grip, then pull the lever up one
more stop (click). Drive the car approximately 400 meters
(1,300
ft.) and release the brake. To recheck the adjustment
of the parking brake see
340 Brakes.
Clutch fluid, checking
In cars equipped with manual transmission and clutch, the hy-
draulic clutch and the brake system share the same reservoir
and the same bralte fluid. Clutch fluid level and brake fluid lev-
el are checked at the same time.
NOTE-
* See 340 Brakes for more information.
See
210 Clutch for information on the clutch and the
hydraulic clutch operating system.
Differential oil level, checking
The E39 differential is filled with lifetime oil that ordinarily
does not need to be changed.
BMW recommends using only
a specially formulated synthetic gear oil
(SAF-XO) that is
available through an authorized
BM\N dealer parts depart-
ment. For additional information on this lubricant and any
other lubricants that may be compatible, contact an
authorized
BMW dealer service department.
< Check rear differential oil level at filler plug (arrow).
- Check lubricant level with car on a level surface:
Level is correct when fluid just reaches edge of filler hole.
If necessary, top up fluid.
Replace filler plug sealing ring.
Install and tighten oil filler plug when oil level is correct.
NOTE-
Use either a 14 mm or 17 mm Allen socket to remove the
drain plug.
If the car is raised in the air, it should be level when
checking or filling final drive fluid level.

Cylinder compression, checking
A compression gauge is needed to make a compression test.
For accurate test, the battery and starter must be capable of
cranking the engine at least
300 rpm, and the engine should
be at normal operating temperature.
NOTE-
Performing a compression test may cause a fault to set in the
ECM and may illuminate the Malfunction
Indicator Light
(MIL). The light can only be turned out using either
BMW
special service scan tools or an equivalent aftermarket scan
tool. Disconnecting the battery will not erase the fault memo-
ry or turn out the light. See OBD On-Board Diagnostics.

4 Remove oil baffle cover from above intake camshaft.
4 Unscrew and remove three cylinder head cover studs (ar-
rows)
at rear of cylinder head.
Set engine to approximate top dead center
(TDC) by turning
crankshaft bolt in direction of rotation (clocltwise when
viewed from front of engine) until camshaft lobes for cylinder
1 face each other (dotted lines) and arrows on camshaft
sprocltets face up.
- Set engine to TDC by aligning "OIP mark of vibration damp-
er with boss cast on lower timing chain cover.
< Lock cranltshaft at TDC:
Remove sealing plug from bore on lower left side of engine
block below starter. Secure crankshaft in
TDC position with
BMW special tool 11 2 300.

Cylinder Head Removal and Installation
- Remove secondary timing chain and sprockets:
Remove mounting nuts from front of intake camshaft
sprocket. Remove and label shim.
CAUTION-
Hold the camshaft stationary (at hex on camshaft) when loos-
ening or tightening sprocket mounting fasteners.
Remove mounting nuts from front of exhaust camshaft
sprocket and remove and label thrust washer.
NOTE-
Where applicable, make note of thrust washerpositions. The
thicker
(0.4 mm) washer is mounted outermost.
- Remove secondary sprockets together with camshaft tim-
ing chain from front of camshafts.
CAUTION-
The camshafts must be locledin the TDCposition using the
special service tool as described earlier: The arrows on the
sprockets should not be used to accurately set the engine to
TDC. The tool holds the camshafts parallel to each other and
NOTE-
Do not remove the sprocl
to
Iceep the sproclefs timed to each other:
CAUTIOI\C
The crankshaft must not be allowed to rotate once the cam-
shaft timing chain is removed. The pistons can
contact the
valves.
Unscrew timing chain guide and remove.
Lift off primary sprocket with chain.
Secure chain with wire to prevent chain from dropping into
lower timing cover.
Unscrew timing case cover to cylinder head bolts (arrows).
NOTE-
Photo shows timing chain guide in place; it should first be re-
moved as described previously.
Remove crankshaft locking tool
(BMW special tool 11 2 300).
Using the crankshaft vibration damper bolt, turn engine op-
posite of normal direction of rotation (counterclocltwise as
viewed from the front) approximately 30". This prevents ac-
cidental contact between valves and pistons during installa-
tion.

Cylinder Head Removal and Installation
NOTE-
BMW special tool 11 4 220 is an adjustable primary chain
tensioner and simulates the function of the hydraulic
tensioner.
- Check that elongated holes in primary sprocket are now cen-
tered to bolt holes in camshaft and chain is free of slack. If
not, reposition sprocket to chain and reinstall.
- lnstall secondary timing chain guide and secondary chain
tensioner. Tighten mounting bolts (tensioner remains locked
down for now using
BMW special tool 11 3 292).
- Install cylinder identification trigger plate to front of intake
camshaft with studs.
- Install spacer to front of intake camshaft.
- Install secondary chain sprockets and chain as an assembly
so that arrows on sprockets are pointing up. Center mounting
holes in sprockets to bolt holes in camshafts.
4 lnstall thrust washers and diaphragm spring to intake cam
sprocket.
I 2hm thrust washer I
- Install shim and torx bolts to exhaust camshaft. Tighten fin-
ger tight; do not torque down.
- Tighten intake sprocket nuts.

Hold the camshaft stationary (at hex on camshaft) when loos-
enino or tiahtenino sorocket mounting bolts and studs.
Tightening torque

- Turn crankshaft approx. 30" in direction of rotation to bring
engine to TDC. Lock crankshaft in TDC position with BMW
special tool
11 2 300.
CAUTION-
The camshafts andcranlshaft must be lockedin the TDCpo-
sition using BMW special tools 11 2 300 and 11 3 240. If the
camshafts and cranl(shaft are not at TDC, the valves can
contact the pistons.

ing so that crankshaft is no longer secured in
TDC position.
- Remove camshaft locking tools from cylinder head.
4 Turn engine over twice in direction of rotation until cylinder 1
intake and exhaust camshaft lobes (arrows) face each other.
- Secure crankshaft in TDC position with BMW special tool 11
2 300.
4 Place BMW special tool set 11 3 240 over camshafts and
measure clearances.
CAUTION-
- If the exhaust side of the tool (A) is not flush with tlie head,
camshaft timing is incorrect Reset camshaft timing as de-
scribed in
117 Camshaft Timing Chain.
* Due to flexible sprocket design, VANOS unit tolerances
and play in the VANOS splines, when the camshaft tim-
ing is set correctly, the intake side of special tool
11 3
240 (6) may be up to 1 mm (0.04 in.) above the surface
of the cylinder head. This is normal. Reassemble en-
gine.
Othe~lise, reset camshaft timing as described in
11 7 Camshaft Timing Chain.
- Remove BMW special tool 11 6 150 from front of cylinder
head.
