otherwise it could fall out resulting in fluid
spillage and possible damage. It may be
necessary to rock the units slightly to
separate them.

1Reverse the procedure described in
Section 8, noting the following points.
2Before attempting to refit the engine, check
that the clutch friction disc is centralised. This
is necessary to ensure that the gearbox input
shaft splines will pass through the splines in
the centre of the friction disc.
3Check that the clutch release arm and
bearing are correctly fitted, and lightly grease
the input shaft splines.
4Check that the engine adapter plate is
correctly positioned on its locating dowels.
5Reconnect the clutch cable to the release
arm, ensuring that it is routed as noted during
removal.
6Fill the engine with the correct grade and
quantity of oil.
7Fill the cooling system.
8Check and if necessary adjust the tension
of the alternator drivebelt.
9Adjust the throttle cable.
1.6 and 1.8 litre (R6A type)
10Reverse the procedure described in
Section 8, noting the points made above.
1Reverse the procedure described in
Section 9, noting the following points.
2Check that the engine adapter plate is
correctly positioned on its locating dowels.
3As the torque converter is only loosely
engaged in the transmission, care must be
taken to prevent the torque converter from
falling out forwards. When the torque
converter hub is fully engaged with the fluid
pump drivegear in the transmission, distance
“A” in illustration 2.24 of Chapter 7B must be
as specified. Incorrect installation of the
torque converter will result in damage to the
transmission.
4As the engine is installed, guide the torque
converter studs through the holes in the
driveplate. When the engine is positioned
flush with the engine adapter plate and the
transmission housing, check that the torque
converter is free to move axially a small
amount before refitting and tightening the
engine-to-transmission bolts.
5Do not tighten the torque converter-to-
driveplate nuts until the lower engine-to-
transmission bolts have been fitted and
tightened.
6Fill the engine with the correct grade and
quantity of oil. 7Fill the cooling system.
8Check and if necessary adjust the tension
of the alternator drivebelt.
9Adjust the throttle cable.
10If applicable, adjust the kickdown cable.
1.8 litre (R2A type)
1Reverse the procedure described in Section
10, noting the following points.
2Before attempting to reconnect the engine
to the gearbox, check that the clutch friction
disc is centralised. This is necessary to ensure
that the gearbox input shaft splines will pass
through the splines in the centre of the friction
disc.
3Check that the clutch release arm and
bearing are correctly fitted, and lightly grease
the input shaft splines.
4Check that the engine adapter plate is

of the alternator drivebelt.
10Adjust the throttle cable.

4As the engine and transmission are
reconnected, guide the torque converter
studs through the holes in the driveplate.
When the engine is positioned flush with the
engine adapter plate and the transmission
housing, check that the torque converter is
free to move axially a small amount beforerefitting and tightening the engine-to-
transmission bolts.
5Do not tighten the torque converter-to-
driveplate nuts until the lower engine-to-
transmission bolts have been fitted and
tightened.
6Reconnect and adjust the selector rod.
7Fill the engine with the correct grade and
quantity of oil.
8Fill the cooling system.
9Check and if necessary top-up the
transmission fluid level.
10Check and if necessary adjust the tension
of the alternator drivebelt.
11Adjust the throttle cable.
12Where applicable, adjust the kickdown
cable.
1The engine mountings incorporate
hydraulic dampers and must be renewed if
excessive engine movement is evident.
2Working in the engine compartment,
unscrew the central nuts securing the engine
mounting brackets to the tops of the
mountings. Recover the washers.
3Apply the handbrake, jack up the front of
the vehicle and support on axle stands (see
“Jacking and Vehicle Support”).
4Working underneath the vehicle, remove
the central nuts securing the mountings to the
crossmember. Recover the washers.
5Raise the engine using a suitable hoist and
lifting tackle attached to the engine lifting
brackets on the cylinder head, or a jack and
interposed block of wood under the sump,
until the mountings can be withdrawn.
6Fit the new mountings, then lower the
engine onto them. Note that the locating pins
on the mountings must engage with the
corresponding holes in the engine mounting
brackets (see illustration).
7Fit the nuts and washers securing the
mountings to the crossmember and tighten
the nuts.
8Lower the vehicle to the ground and fit the
nuts and washers securing the engine
mounting brackets to the mountings. Tighten
the nuts.

4Repeat the procedure given in paragraphs
2 and 3 for the remaining valves, keeping all
components identified for location so that
they can be refitted in their original positions.
Note that the inlet valve springs are fitted with
metal dampers. The damper is an integral part
of the spring and cannot be removed (see
illustration).
Reassembly
5Commence reassembly by lubricating the
valve stems and guides with SAE 80/90
hypoid oil, then insert the valves into their
original guides.
6Refit the spring seats over the valve stems.
7Wrap a thin layer of adhesive tape over the
collet grooves of each valve, then smear the
new oil seals with a little hypoid oil and slide
them down the valve stems onto the spring
seats. Use a suitable metal tube to seat the
seals, then remove the adhesive tape from the
valves (see illustration).
8Working on each valve in turn, fit the valve
spring and cap, then compress the spring
using the valve spring compressor and fit the
split collets to the groove in the valve stem.
Release the compressor and tap the end of
the valve stem with a soft-faced mallet to
settle the components. If the original
components are being refitted, ensure that
they are refitted in their original locations.
9Refit the camshaft.
1.6 and 1.8 litre (R6A type)
10Proceed as described in paragraphs 1 to 9
inclusive, but note that no dampers are fitted
to the inlet valve springs on the 1.6 litre engine.Refer to Section 23, Chapter 2, Part A but
pay particular attention to the note at the
beginning of the Section as all CVH engines
are fitted with hardened valve seats.
Note: A new camshaft oil seal and new rocker
arm securing nuts should be used when
refitting.
1.8 litre (R2A type)
Removal
1Remove the cylinder head.
2Unscrew the securing bolts and remove the
rocker arm guides, rocker arms, and cam
follower guide retainers, then lift out the cam
follower guides and the cam followers. Keep
all components in the correct order so that
each component can be refitted in the original
position if it is to be re-used. 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.
3Prise out the camshaft oil seal, taking care
not to damage the surface of the camshaft. If
necessary use self-tapping screws and a
suitable pair of grips to withdraw the seal.4Unscrew the two securing bolts and
withdraw the camshaft thrustplate from the
front of the cylinder head.
5Carefully withdraw the camshaft from the
front of the cylinder head, taking care not to
damage the bearings. If necessary, loosely
refit the camshaft sprocket and bolt to aid
removal.
Inspection
6Examine the surfaces of the camshaft
journals and lobes, and the cam follower rollers
for wear. If wear is excessive, considerable
noise would have been noticed from the top of
the engine when running, and a new camshaft
and followers must be fitted. It is unlikely that
this level of wear will occur unless a
considerable mileage has been covered. Note
that the cam followers cannot be dismantled
for renewal of individual components.
7Check the camshaft bearings in the cylinder
head for wear. If excessive wear is evident, it
may be possible to have the head machined by
a suitably equipped engineering workshop to
enable a camshaft with oversize bearing
journals to be fitted. The only other course of
action available is renewal of the cylinder head.
8Check the cam follower bores in the
cylinder head for wear. If excessive wear is
evident, the cylinder head must be renewed.
9Check the cam follower oil ports and the oil
holes in the cylinder head for obstructions
(see illustrations).
Refitting
10Commence refitting by lubricating the
camshaft, bearings and thrustplate with
