By the use of VCT for the intake and exhaust
camshafts it is possible to attain maximum torque
across a wide engine speed range.
Cylinder head
The cylinder head consists of two parts. The top
half of the cylinder head consists of a valve cover
with integral camshaft bearing caps.

CAUTION: Before removal, mark the
camshafts as the intake and exhaust
camshafts can be mixed up.
A reference mark for the CMP sensor is machined
into each camshaft. When the camshafts are set
precisely to the timing marks, the machined mark
on the exhaust camshaft is located roughly at the
5 o'clock position and the machined mark on the
intake camshaft is located at 8 o'clock.
When changing the toothed belts it is not necessary
to dismantle the camshaft adjustment units. A
special tool prevents the VCT control units from
turning during the adjustment process by locking
the two VCT control units to one another.
A further special tool is needed to fix the camshafts
in the adjustment position. The special tool
engages in corresponding recesses for the
reference marks on the CMP sensors. Each camshaft is fixed in place using four bearing
caps and the bearing cap VVT. The bearing caps
must not be changed around and must always be
fitted in their original positions.
The VCT control units for the intake and exhaust
camshafts are moved into the locked base position
when the engine is stopped through the
engagement of a spring-loaded locking pin. The
movement to the locked base position is assisted
by the tensile force of the timing belt for the intake
VCT control unit. With the exhaust VCT control
unit, a spring inside the control unit additionally
assists in reaching the locked base position. The
intake VCT control unit is in the "retarded timing"
position and the exhaust VCT control unit is in the
"advanced timing" position when in the locked base
position. The lock is hydraulically released when
the engine is started depending on the oil pressure.
The mechanical valve tappets are maintenance
free.

The front engine cover must always be fitted when
checking and adjusting the valve timing or timing
belt tension, as the timing marks for both camshaft
pulleys are provided on its front end.
Correct timing belt tension is ensured by the
automatic timing belt tensioner.
No direction of movement is specified when using
a new timing belt. If, however, the old timing belt
is reused, the direction of movement must be
marked prior to removal.
Once the timing belt has been correctly tensioned,
the engine must be rotated by hand two turns
clockwise at the crankshaft in order to allow a subsequent check of the timing belt tension and
adjustment.
Cylinder block
The cylinder block consists of three parts. These
are the cylinder block, the lower crankcase and the
sump pan. The cylinder block has five cylinder
liners made of cast iron, which cannot be replaced.
The pistons are made of a homogeneous aluminum
alloy with a graphite coating on the sides. This
coating serves to reduce friction and dampen noise.
The pistons are cooled from below via oil-spray
nozzles screwed into the cylinder block.

Located on the drive side of the crankshaft are two
sets of splines. The inner splines drive the oil
pump. The outer splines engage in the timing belt
pulley. The timing belt pulley can only be fitted onto the outer splines in a particular position. For this
purpose, one spline on the timing belt pulley and
one on the crankshaft have been made wider. The
dowel fixes the vibration damper in place.
