the chain. Secure the chain using a cable-tie
through two of the chain links to prevent it
from dropping off the crankshaft sprocket.
9 Using a suitable pair of pliers, extract the
circlip from the chain tensioner arm pivot pin,
taking care not to drop it into the timing case,
then withdraw the pivot pin from the tensioner
arm. If the pivot pin proves difficult to
withdraw, an M6 bolt can be screwed into the
end to facilitate removal (see illustration).
10 Lift the tensioner arm from the timing case.
11 Lift the tensioner plunger assembly from the
cylinder head, and discard it (see illustration). 12 Take note of the markings on the camshaft
bearing caps, then progressively unscrew the
bearing cap securing nuts.
13 Remove the bearing cap securing nuts,
then lift off the camshaft oil spray bars, and
the timing chain guide plate (see illustration).
14 Lift off the bearing caps, and then lift out
the two camshafts (see illustrations).
15 Withdraw the cam followers from their
locations in the cylinder head, keeping them in
order so that they can be refitted in their
original locations (see illustration). It is
advisable to store the cam followers upright in
an oil bath until they are to be refitted. Ensure
that the depth of oil is sufficient to fully cover
the cam followers.
16 Working at the front of the cylinder head,
unscrew the three small M8 cylinder head
bolts which are accessible through the timing
case (see illustration).
17 Working in the reverse order to that shown
for tightening the cylinder head bolts (see
illustration), progressively loosen the
remaining cylinder head bolts, and withdraw
them from the cylinder head.
18 Lift the cylinder head from the block. If the
cylinder head is stuck, tap it free with a soft-
faced mallet. Do not insert a lever into the joint
between the cylinder head and block, as this
may result in damage to the mating faces.
Place the cylinder head on blocks of wood to
prevent damage to the valves.
19 Recover the gasket, and the locating
dowels if they are loose, noting the positions
of the locating dowels.
20 Commence refitting as follows.
21 Turn the crankshaft so that No 1 piston is
approximately 20.0 mm (0.8 in) before TDC.
This precaution will prevent possible contact
between the valves and pistons.
22 Make sure that the mating faces of the
cylinder block and cylinder head are perfectly
clean, then refit the locating dowels (where
applicable) and locate a new gasket over the
2B•12 DOHC engine

The inlet camshaft is normally
identified by a green paint
mark. If necessary, identify
the camshafts so that they
can be refitted in their correct positions.
Warning: Take care when removing
the plunger assembly; injury could
result if the piston flies out. A new
timing chain tensioner plunger
assembly should be installed on refitting.
