2A•2 Engine in-car repair procedures
3261 Jaguar XJ6
1 General information
This Part of Chapter 2 is devoted to in-car
repair procedures for the in-line six-cylinder
engines. All information concerning engine
removal and refitting and engine block and
cylinder head overhaul can be found in Part B
of this Chapter.
The following repair procedures are based
on the assumption that the engine is installed
in the car. If the engine has been removed
from the car and mounted on a stand, many of
the steps outlined in this Part of Chapter 2 will
not apply. We have photographed some in-
car engine procedures with the engine on a
stand for photographic purposes.
The Specifications included in this Part of
Chapter 2 apply only to the procedures
contained in this Part. Part B of Chapter 2
includes the Specifications necessary for
cylinder head and engine block rebuilding.
2 Repair operations possible
with the engine in the car
Many repair operations can be
accomplished without removing the engine
from the car.
Clean the engine compartment and the
exterior of the engine with some type of
degreaser before any work is done. It will
make the job easier and help keep dirt out of
the internal areas of the engine.
Depending on the components involved, itmay be helpful to remove the bonnet to
improve access to the engine as repairs are
performed (refer to Chapter 11 if necessary).
Cover the wings to prevent damage to the
paint. Special pads are available, but an old
bedspread or blanket will also work.
If vacuum, exhaust, oil or coolant leaks
develop, indicating a need for gasket or seal
renewal, the repairs can generally be made
with the engine in the car. The intake and
exhaust manifold gaskets, crankshaft oil seals
and cylinder head gasket are all accessible
with the engine in place (although rear oil seal
renewal involves removal of the transmission).
The sump is difficult for a home mechanic to
replace without a hoist and other specialised
equipment, since the front suspension,
steering and crossmember must be lowered
to allow enough clearance for sump removal.
If such equipment is not available, the
alternative would be to remove the engine for
renewal of the sump or oil pump. Note:We
assume that the home mechanic does not
have access to the specialised equipment,
and have photographed our subject engine
out of the car for some procedures.
Exterior engine components, such as the
intake and exhaust manifolds, the water
pump, the starter motor, the alternator, the
distributor and the fuel system components
can be removed for repair with the engine in
place.
Since the cylinder head can be removed
with the engine in-car, camshaft and valve
component servicing can also be
accomplished. Renewal of the timing chains
and sprockets is also possible with the engine
in-car.
3 Top Dead Centre (TDC) for
number one piston- locating
1
Note:The following procedure is based on the
assumption that the distributor is correctly
installed. If you are trying to locate TDC to refit
the distributor correctly, piston position must
be determined by feeling for compression at
the number one spark plug hole, then aligning
the ignition timing marks (see paragraph 8).
1Top Dead Centre (TDC) is the highest point
in the cylinder that each piston reaches as it
travels up the cylinder bore. Each piston
reaches TDC on the compression stroke and
again on the exhaust stroke, but TDC
generally refers to piston position on the
compression stroke.
2Positioning the piston(s) at TDC is an
essential part of many procedures such as
camshaft and timing chain/sprocket removal
and distributor removal.
3Before beginning this procedure, be sure to
place the transmission in Neutral and apply
the handbrake or block the rear wheels. Also,
disable the ignition system by detaching the
coil wire from the centre terminal of the
distributor cap and grounding it on the engine
block with a jumper wire. Remove the spark
plugs (see Chapter 1).
4In order to bring any piston to TDC, the
crankshaft must be turned using one of the
methods outlined below. When looking at the
timing chain end of the engine, normal
crankshaft rotation is clockwise.
a) The preferred method is to turn the
crankshaft with a socket and ratchet

5Pull the headlight out slightly and
disconnect the electrical connector from the
rear of the light, then remove the light from the
vehicle.
6To refit, position the new unit close enough
to connect the electrical connector. Make
sure that the numbers moulded into the lens
are at the top.
7Refit and tighten the retaining ring. Test the
headlight operation.
8The remainder of the refitting is the reverse
of removal.
Halogen gas-filled bulbs
9Disconnect the electrical connector from
the bulb assembly. Rotate the headlight bulb
connector 1/4-turn anti-clockwise (viewed
from the rear) (see illustration).
10Withdraw the bulb assembly from the
headlight housing.
11Without touching the glass with your bare
fingers (see the Warningat the start of the
Section), insert the new bulb assembly into
the headlight housing and rotate the bulb
socket 1/4-turn clockwise to refit it.
12Plug in the electrical connector and test
headlight operation.
18 Headlights- adjustment

Note:The following procedure is intended for
emergency use only, and we strongly
recommend that the headlight aim is only
checked using optical beam-setting
equipment. It is important that the headlights
are aimed correctly. If adjusted incorrectly
they could blind the driver of an oncoming
vehicle and cause a serious accident or
seriously reduce your ability to see the road.
The headlights should be checked for proper
aim every 12 months and any time a new
headlight is installed or front end body work is
performed.
1Adjustment should be made with the
vehicle sitting level, the petrol tank half-full
and no unusually heavy load in the vehicle.2Early models with sealed beam headlights
have four adjusting knobs protruding through
the backside of the radiator support. The
vertical (up and down) adjustment knobs are
located above the headlight and the horizontal
(left to right) adjusting knobs are located
below the headlight (see illustration).
3On later models with halogen bulbs,
adjustments are made in the same manner as
described in the previous step, except there
are only two adjusting knobs which tilt the
headlight housing to the desired angle.
4If the headlight housing has been replacedor the vehicle has suffered front-end damage,
refer to following procedure.
5This method requires a blank wall, masking
tape and a level floor.
6Position masking tape vertically on the wall
in reference to the vehicle centreline and the
centrelines of both headlights (see
illustration).
7Position a horizontal tape line in reference
to the centreline of all the headlights. Note:It
may be easier to position the tape on the wall
with the vehicle parked only a few inches
away.
