Cylinder Head Removal and Installation --
Remove bolts (arrows) holding timing chain cover to cylinder
head. (Photo shows camshafts and camshaft bearing caps in
place).
4 Using BMW special tool 11 2 250 or equivalent, loosen cylin-
der head bolts in several stages, in sequence shown. Discard
head bolts.
NOJE-
BMW special tool 11 2 250 is a thin-walled Torx El2 socket
with an extended reach. The cylinder head bolts are re-
cessed into the head below the
camshaft towers with little
working space.
- Lift off cylinder head. Refer to 116 Cylinder Head and Val-
vetrain for cylinder head reconditioning information.
Cylinder head, installing, M52 TU and M54
engines
Clean cylinder head and gasket surfaces of cylinder bloclc
and all timing chain covers.
CAUTION- Remove foreign matter and liquid from bolt holes. Trapped oil
or coolant in bolt holes can cause damage to
blocl~,
CAUJION-
Do not use a metal scraper or wire brush to clean the alumi-
num cylinder head or pistons. If necessary, use a hard wood-
en orplastic scraper. Also available are abrasive discs to be
used in conjunction with an electric drill. Be sure to use the
correct disc for the type of metal being cleaned.
Evaluate cylinder head as shown in
116 Cylinder Head and
Valvetrain.
NOTE- If the cylinder head has been machined, a special 0.3
mm
(0.01 1 in.) thicker gasket should be installed. The thicker
gasket is available from an authorized
BMW dealer and
should be marked accordingly
Cylinder head and valve specifications are covered in 116
Cylinder Head and Valvetrain.

CYLINDER MEAD REMOVAL AND
INSTALLATION (M62 ENGINE)
This procedure covers cylinder head removal and installation
for the
M62 V-8 engine. Procedures forthe M62 TU VANOS
engine are not covered in this manual.
Intake manifold, left cylinder head, and right cylinder head re-
moval and installation are written as separate procedures.
The intake manifold must be removed before the cylinder
heads can be removed.
WARNING
-
Due to risk of personal injuv be sure the engine is cold be-
fore beginning the removal procedure.
Cylinder head removal and installation requires multiple spe-
cial service tools. Read the entire procedure before beginning
the repair.

Remove intake manifold fasteners (A).
Carefully lift intake manifold off engine while checking that all
hoses and harnesses have been disconnected.

- Remove intake manifold as described earlier
- Remove left side exhaust manifold. See 180 Exhaust Sys-
tem.
- Drain engine coolant, then remove viscous clutch cooling
fan. See
170 Radiator and Cooling System.
WARNING -
Use extreme caution when draining and disposfng of eng~ne
coolant. Coolant is poisonous and lethal to humans andpets.
Pets are attracted to coolant because of its sweet smell and
taste.
Seek med~cal attention immediately if coolant is ingest-
ed.
4 Remove coolant manifold mounting fasteners and carefully
remove manifold.
NOTE-

- Clean cylinder head and block sealing surfaces of gasket
debris, making sure no debris drops into coolant or oil pas-
sages.
- Clean cylinder head bolt holes and check condition of
threads.
< Check cylinder head locator sleeves (arrows) for damage.
If the cylinder head has been machined, a special
0.3 mm
thicker gasket should be installed. The thicker gasket is avail-
able through an authorized
BMW dealer and should be
marked accordingly.
- Place new cylinder head gasket over locating sleeve on
block.
The word
"OBEN" or "TOP" (arrow) printed on the gasket,
must face up.
Set lefl side cylinder head in position on cylinder block while
pressing oil separator outward.
CAUJION-
Male sure the crankshaft, which had been rotated approxi-
mately
45" opposite the direction of engine rotation from
TDC, is still in thatposition before installing the cylinder head.
All pistons must be out of
TDCposition to prevent valvelpis-
ton contact.
- Install new cylinder head bolts and washers finger tight. Be
sure not to remove coating from new cylinder head bolts.
