Remove sealing plug from bore at bellhousing. Secure crank-
shaft in
TDC position with BMW special tool 11 2 300 (ar-
row).
- Remove cylinder head cover studs at rear of cylinder head.
< Place BMW special tool 11 3 240 over camshafts ends and
measure clearance of tool to cylinder head surface.
NOTE-
If the exhaust side of the tool (A) is not flush with the head,
adjust camshaft timing as described below.
Due to flexible sprocket design and VANOS control unit tol-
erances and play, the
intake side of special tool 11 3 240
(B) may be up to 1 mm (0.04 in) above the surface of the
cylinder head. This is normal. Reassemble engine. Other-
wise, adjust camshaft timing as described below.
- Remove double VANOS control unit. See VANOS control
unit, removing
(M52 TU and M54 engines).
< Press down on secondary chain tensionerand lock into place

I Camshaft Timing Chain - --
Install BMW special tool 11 6 150 (VANOS setup bracket) to
front of cylinder head timing case. Tighten nuts
(arrows) by
hand, and then tighten down uniformly until special tool is in
full contact with cylinder head.
CAUTION-
Male sure all gasket material is removed from face of cylin-
der head. Clean
sealins face and keep free of oil.
Secure camshaft impulse sprockets and wheels:
Pretighten Torx screws
(A) on exhaust camshaft impulse
wheel to approx.
5 Nm (44 in-lb).
Pretighten mounting nuts
(B) on exhaust and intake
sprocket assemblies to approx.
5 Nm (44 in-lb).

- Remove flywheel locking tool from transmission bellhousing
so that crankshaft is no longer locked.
- Remove camshaft locking tools from rear of cylinder head.
- Crank engine over twice by hand in direction of rotation until
cylinder
1 intake and exhaust camshaft lobes face each other - again.
- Secure crankshaft with BMW special tool 11 2 300.

NOJE-
If the exhaust side of the tool (A) is not flush with the head,
camshaft timing
Is incorrect. Repeat camshaft timing pro-
cedure.
* Due to flexible sprocket design and VANOS control unit tol-
erances and play, the
intake side of special tool 11 3 240
(6) may be up to 1 mm (0.04 in) above the sudace of the
cylinder head. This is normal. Otherwise, repeat camshaft
timing procedure.

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.
