General
WARNING-
Never run the engine in tile work area unless it is well-ven-
tilated. The exhaust should be vented to the outside. Car-
bon monoxide (CO) in exhaust kills.
Remove all neckties,
scarfs, loose clothing, or jewelry
when working near a running engine or power tools.
Tuck in shirts. Tie long hair and secure it under a cap.
Severe injury can result from these things being
caugiit
in rotating parts.
Remove rings, watches, and bracelets. Aside from the
dangers of moving parts, metallic jewelry conducts
electricity and may cause shorts, sparks, burns, or
damage to the electricalsystem when accidentally con-
tacting the battery or other electrical terminals.
Disconnect the battery negative
(-) cable whenever
working on or near the fuel system or anything that is
electrically powered. Accidental electrical contact may
damage the electrical system or cause a fire.
Fuelis highly flammable. When working around fuel, do
not
smoke or work near heaters or other fire hazards.
Keep an approved fire extinguisher handy.
The fuel system is designed to retain pressure even
when the ignition is off When worlcing with the
fuelsys-
tem, loosen the fuel lines slowly to allow the residual
pressure to dissipate gradually. Take precautions to
avoid spraying fuel.
. Illuminate the worlc area adequately and safely Use a
portable safety light for worlcing inside or under the car.
A fluorescent type
light is best because it gives off less
heat. If using a light with a normal incandescent bulb,
use rough service bulbs to avoid
breakage. The hot fil-
ament of an accidentally broken bulb can ignite spilled
fuel or oil.
Keep sparks, lighted matches, and any open flame
away from the top of the battery. Hydrogen gas
emitted
by the battery is highly flammable. Any nearby source
of ignition may cause the battery to explode.
Never lay
tools or parts in the engine compartment or
on top of the battery. They may
fallinto confinedspaces
and be difficult to retrieve, become caught in belts or
other rotating parts when the engine is started, or
cause electrical shorts and damage to the electrical
system.

I Engine Removal and Installation
WARNING -
Use extreme caution when draining and disposing of engine
coolant. Coolant is poisonous andlethal to humans andpets.
Pets are attracted to coolant because of its sweet smell and
taste. Seek medical attention immediately if coolant is ingest-
---
Working at rear of intake manifold:
Disconnect brake booster vacuum line (A).
Disconnect fuel tank vent line
(6).
Disconnect hoses (C and D) at coolant manifold
- Remove transmission harness support (E).
- Remove oil filter housing assembly from fender:
- Remove oil filter housing mounting fasteners.
Use stiff wire to secure oil filter housing to engine.
NOTE-
Do not disconnect oil lines from filter housing.
4 Disconnect supply and return fuel lines (where applicable) at
or near fuel rail. Plug open fuel lines.
NOTE-
BMW uses three styles of fuel line connections; a slngle use
clamp, a locking fitting that uses special tool
16 7 050 to re-
lease, and a
quiclc release sleeve (arrows) that disconnects
the line when depressed.
WARNING-
Fuel In fuel line is under pressure (approx. 3 - 5 bar or45 -
75 psi) and may be expelled. Do not smoke or worlc near
heaters or other fire hazards. Keep a fire extinguisher
handy. Before disconnecting fuel hoses, wrap a cloth
around fuel hoses to absorb any lealcing fuel. Catch and
dispose of escaped fuel. Plug all open fuel lines.
. Always unscrew the fuel tank cap to release pressure
in the tank before worlcing on the tank or lines.
< Remove air filter housing and mass air flow sensor:
Disconnect mass air flow sensor (A) and
intalte air temper-
ature sensor
(6) electrical harness connectors.
. Remove air filter housing mounting fastener (arrow).
Loosen intake hose clamp (C).
M62 engine: Remove hose at idle air stabilizer.
Remove air filter housing with mass air flow sensor.
Remove intalte hose from throttle body.

< lnstall engine lifting device (BMW 11 0 000 or equivalent) to
front and rear engine supports and raise engine until it's
weight is supported. Detach engine mounts.
a Watch carefully for hoses and electrical wires that might
snag.
- installation is reverse of removal:
Replace all gaskets, O-rings and seals.
V-8 engine mounts have two sets of mounting holes. E39
cars use front most mounting holes.
* On cars with automatic transmission, use new O-rings at
ATF cooler lines.
Use new alignment sleeves when installing transmission.
Be sure engine drive belts properly engage pulley grooves.
When installing belt, preload tensioner to stop (toward
belt), then tighten tensioner clamping nut.
lnstall front exhaust pipes using new gasltets and copper
paste and new mounting hardware. See
180 Exhaust
System.
Change engine oil and filter. Check all other fluid levels as
described in
020 Maintenance.
Refill and bleed cooling system as described in
170 Radi-
ator and Cooling System.
CAUTION-
Do not interchange knoclc sensor harness connectors. Seri-
ous engine damage may result

Turn engine over twice in direction of rotation until cylinder 1
intake and exhaust camshaft lobes (arrows) face each other.
- Lock 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.
NOTE-
@ If the exhaust side of the tool (A) is not flush with the head,
camshaft timing is incorrect. Reset camshaft timing as de-
scribed in 11
7 Camshaft Timing Chain.
Due to flexible sprocket design, VANOS unit tolerances
and play in the VANOS splines, when the camshaft timing
is set correctly, the intake side of special tool set
11 3 240
(B) may be up to 1 mm (0.04 in.) above the suiface of the
cylinder head. This is normal. Reassemble engine. Other-
wise, reset camshaft timing as describedin 1
l?Camshaft
Timing Chain.
- Remove BMW special tool 11 6 150 from front of cylinder
head.
4 Clean contact edges of cylinder head face and VANOS unit
and apply a thin coat of Three Bond
12090 or equivalent
sealing compound to surfaces.
CAUTION-
Male sure all gasket material is removed from face of cyl-
inder head. Clean sealing face and keep free of oil.
Check locating dowel
(A) and dowel sleeve (B) at top
of cylinder head for damage or incorrect installation.
- Using a new steel gasket, install VANOS unit to front of cyi-
inder head. See 117 Camshaft Timing Chain.
NOTE-
If VANOS control unit is being replaced, be sure to check and
adjust camshaft timing as described in 117 Camshaft Tim-
ing Chain.
- Reinstall engine lifting eye.
- Reconnect electrical harness connectors to camshaft posi-
tion sensors and
VANOS solenoid valves.
