4 Remove VANOS unit:
Remove fasteners from engine support eye.
Remove VANOS mounting nuts (arrows) from cylinder
head. Slide VANOS control unit and metal gasltet off.
NOJE-
The VANOS control unit will contain residual oil. Place
shop towels beneath adjustment unit when removing.
If the VANOS control unit is replaced, or if repair operations
are completed that may change camshaft timing, the cam-
shaft timing must be checked as described in VANOS tim-
ing,
checlcing and adjusting (M52 JU and M54
engines).
CAUJION-
Do not crank the engine with VANOS unit removed.
Piston/valve interference may result.

. Make sure all gaskel material is removed from lace of
cyl~nder head. Clean sealing lace and keep lree of oil.
Checklocating dowel (A) and dowelsleeve (B) at top of

JE -
If the Double VANOS control unit is beino reolaced. be -.
sure to check and adjust camshaft timing, see VA NOS
timing, checking and adjusting (M52 JU and M54 en-
gines).
* If work being carried out has no effect on camshaft timing,
it is not necessary to recheck the timing. It is recommend-
ed, however, that the VANOS operation be checked using
a compatible scan tool once the engine is running.

4 The procedure outlined below assumes that the camshafts
are locked in the TDC installation position with special lock-
ing tools as shown earlier.
4 lnspect timing chain sprocltets and chain. Inspect guide rail
and tensioner rail
(arrows) for grooves caused by chain con-
tact. Replace any part that is worn or damaged.
NOTE-
If any sprocl(ets are being replaced due to wear, the chain
should also be replaced.
If the crankshaft sprocket requires
replacement, the oil pump
drive sprocket and chain must be
removed. See
119 Lubrication System for oilpump removal
information.
- If removed, reinstall timing chain tensioning rail, reversing
rail, and guide rail.
If tensioning rail was removed, replace O-ring at tensioning
rail oil guide.

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.
