Engine - TDV6 3.0L Diesel - Engine - Overview
Description and Operation
OVERVIEW
The 3.0 liter diesel engine is a V6 configuration unit with 2 banks of 3 cylinders arranged at 60 degrees to each other.
There are 4 valves per cylinder, which are operated by 2 overhead camshafts per cylinder bank.
The cylinder block is cast in compacted graphite iron, which uses less material to produce compared to a conventional cast
iron block. This provides reduced weight and length with superior structural capabilities.
The cylinder heads are cast aluminum with a moulded plastic camshaft cover with an integral air intake. The single-piece
structural oil pan is high pressure die cast from aluminum. The exhaust manifolds are cast from an iron alloy. A moulded
plastic acoustic cover is fitted over the upper engine to absorb engine-generated noise.
A low compression ratio of 16:1 contributes to improved emissions quality, quieter combustion and compatibility with the
engine’s unique forced induction system. For additional information refer to Intake Air distribution and Filtering.
The low compression ratio also means less heat build-up in the piston bowl and more efficient fuel burn, resulting in the
production of lower levels of pollutants. It also assists with cold starting allowing a faster cranking speed.
The engine is available in two power output forms. The power difference is achieved by changes to the engine calibration
within the ECM (engine control module) and other vehicle control modules.
• NOTE: It is not possible to re-configure a lower power output engine to the higher output specification.

3 Oil pan
The use of compact graphite iron allows the cross sectional areas of the casting to be reduced, compared with a
conventional gray cast iron block. This ensures reduced engine weight and length, with higher structural capabilities.
To maintain the stiffness of the bottom end of the cylinder block and crankshaft system, the cylinder block has a deep
skirt and bearing cap design. Each of the main bearing caps is double bolted at each side of the crankshaft bearing and
cross bolted back to the cylinder block.
Lubrication oil is distributed through the cylinder block, via a main oil gallery and channels bored in the block, to all critical
moving parts. These channels divert oil to the main and connecting rod bearings via holes machined into the crankshaft.
A tapping at the rear of the cylinder block connects a pipe to the turbochargers by means of banjo connections. Oil is
supplied, under pressure via this tapping, from the oil pump to provide lubrication for the bearings of the turbochargers.
Cylinder cooling is achieved by coolant circulating through chambers in the cylinder block casting.
Two hollow metal dowels are used to locate the cylinder heads to the cylinder block, 1 on each side at the rear of the unit.
A port is included at the RH (right-hand) and LH (left-hand) side of the cylinder block, below each of the turbochargers, to
connect the turbochargers oil return pipe to the oil pan.
Two coolant drain plugs are installed in the cylinder block; one is fitted in the rear RH side, and the other is fitted in the
middle of the cylinder block on the LH side.

The crankshaft is forged steel and fillet rolled with induction hardened journals, which run in 4 bearings with clamped 2
layer bearing shells. The upper and lower shells of bearing number 4 are flanged, which limits the end float of the
crankshaft. The main bearing caps are double bolted and cross bolted to increase the strength and rigidity of the engine
block.
The main bearings are aluminum/tin split plain selective bearings. An oil groove in the top half of each bearing transfers
oil into the crankshaft for lubrication of the connecting rod bearings. The upper and lower shells of bearing number 4
contain integral thrust washers, which limits the end float of the crankshaft.
ItemDescription
1 Housing
2 Seal
3 Crankshaft
4 Rear oil seal retainer
5 Bolt (10 off)
The rear main oil seal and retainer assembly is a one-piece unit and is supplied with its own plastic fitting sleeve. The
seal and retainer have 2 locating dowels, 10 fixing bolts and a rubber seal. In addition, the retainer has a location for the
crankshaft position sensor. For additional information refer to 303-14A Electronic Engine Controls.
A torsional vibration crankshaft damper pulley is bolted to the front of the crankshaft.
The trigger wheel consists of 60 magnets minus 2 for ECM crankshaft position reference and synchronization. The magnets
cannot be seen on the trigger wheel, which therefore can only be positioned using a special tool. For additional information
refer to 303-14A Electronic Engine Controls.
If the trigger is removed for any reason, then a new trigger wheel must be fitted.
The oil pan is secured to the cylinder block with 2 dowels, 2 locator pins for the gasket and 18 retaining bolts; 3 different
lengths of bolts are used:
M6 x 20 (6 off)
M8 x 75 (4 off)
M6 x 105 (8 off).
Iron inserts, cast into the main bearing supports of the stiffening frame, minimize main bearing clearance changes due to
heat expansion.
A gasket seals the joint between the oil pan and the cylinder block.
An oil pick-up pipe with integral strainer locates in the oil pan to provide oil to the crankshaft driven oil pump.
An ultrasonic sensor provides an electronic indication when the oil in the oil pan is low or high. This removes the
requirement for the mechanical dipstick. An advantage in comparison with the static 'dipstick' method is that all marginal
influences, for example vehicle being on a slope, lateral and longitudinal acceleration, are compensated for by averaging.
The values determined can be used to signal that the minimum oil level has been reached or to display the current oil
level if required.
The sensor is mounted inside the oil pan where it sends an ultrasonic pulse vertically upward, it then measures the time
for the pulse to be reflected back from the top surface of the oil.
Warnings will be displayed in the message center if the oil level is not maintained within the safe operating levels
(minimum and maximum). A warning will also be displayed if there is a fault with the oil level monitoring system.
The pistons are made from aluminum alloy and are fitted with 3 rings. The piston crown incorporates a pronounced bowl;
this forms the combustion chamber, which promotes swirl and turbulence necessary for good combustion and improved
emissions. In addition, the piston skirt has a molybdenum-coated surface, which counteracts scoring of the cylinder bore
and piston.
The piston also incorporates a double wave gallery within the piston crown to enhance piston cooling. The pistons are
supplied oil by means of spray jets located in the cylinder block oil gallery. These jets ensure optimum piston cooling to
counteract the high temperatures generated by the combustion process.
Each piston is installed on a piston pin located in a aluminum/tin bushing in the connecting rod.
The piston top ring is a taper type and is fitted with the taper to the top of the piston. All rings marked 'top' are
assembled with 'top' uppermost. All rings must be spaced evenly around the piston before installing. The circumference
gap of the double bevelled oil control ring must be opposite the spiral control joint.
Timing belt adjustment is carried out by an eccentric type tensioner mounted on the RH front face of the cylinder block.
A primary drive cover is made up from 3 separate plastic mouldings. The covers are secured to the front of the cylinder
block and cylinder heads with 15 bolts and 1 stud and nut. The 2 upper covers are partially sealed with a rubber seal.
Secondary Drive
ItemDescription
1 Timing chain
2 Bolts
3 Intake camshaft

5 Tensioner firing pin
Secondary drive is provided by 2 short crossover chains, which transfer drive from the exhaust camshaft gears to the intake
camshaft gears. The crossover drives are located at the rear of the RH cylinder bank and the front of the LH cylinder bank.
This allows for a much shorter and simpler run for the main camshaft drive belt at the front of the engine.
Each crossover chain is tensioned via an automatic chain tensioner, which acts directly on the chains via a guide rail. The
tensioners are located between the exhaust and intake camshafts at the front or rear of the cylinder head, depending on
the cylinder bank.
The tensioner firing pin holds the automatic chain tensioner in a compressed state to aid installation.

The aluminum gravity die cast cylinder heads are unique to each cylinder bank. Eight deep-seated bolts help reduce
distortion and secure each cylinder head to the cylinder block. The cylinder head bolts are located beneath the camshafts,
4 under the intake camshaft and 4 under the exhaust camshaft. Two hollow dowels align each cylinder head with the
cylinder block.
The cylinder head gasket is a 3-layer, laminated steel type and is available in 5 different thicknesses. The choice of gasket
thickness is dependent on the maximum piston protrusion. Gasket thickness is identified by serrations cut into the front
end of the gasket.
The cylinder head has 4 ports machined at each cylinder location, 2 exhaust ports and 2 intake ports. One of the intake
ports is helical and functions as a swirl port, the other is arranged laterally as a tangential port and functions as a charge
port.
The camshafts are of a hollow steel tube construction, with pressed on sintered lobes. Each camshaft is retained by
aluminum alloy caps, 5 for the exhaust camshafts and 4 for the intake camshafts. Location letters, A to I for the intake
camshaft and R to Z for the exhaust camshaft, are marked on the outer faces of the caps for each cylinder head.
The LH cylinder bank exhaust camshaft is machined to accept a rear camshaft gear. The rear camshaft gear provides drive
for the high-pressure fuel pump. For additional information refer to 303-04A Fuel Charging and Controls.
The exhaust camshaft gear of the LH cylinder head also incorporates a trigger wheel, which is used in conjunction with the
camshaft sensor to measure engine position. For additional information refer to 303-14A Electronic Engine Controls.
The RH cylinder head exhaust camshaft is machined at the rear end to provide a drive connection for the tandem pump.
The fuel injection nozzles are centrally mounted above each cylinder. For additional information refer to 303-04A Fuel
Charging and Controls.
The glow plugs are arranged centrally on the intake side of the cylinder heads, between the 2 intake ports of each cylinder.
For additional information refer to 303-07D Glow Plug System.
The engine lifting eyes are bolted to the cylinder head, 1 at the front and 2 at the rear, 1 per cylinder head.

The camshaft covers are manufactured from vinyl ester composite. The RH bank camshaft cover incorporates an outlet for
the full load engine breather and the engine oil filler cap. The LH bank camshaft cover incorporates an outlet for the part
load engine breather. For additional information refer to 303-08A engine Emission Control.
Silicon rubber in-groove gaskets seal the joints between the camshaft covers and the cylinder heads. Together with
spacers and seals on the camshaft cover fasteners, they also isolate the covers from direct contact with the cylinder
heads, to reduce noise.

Tandem Pump
ItemDescription
1 Tandem pump connections
2 Bolt (2 off)
3 Nut
4 Bracket (emission hose)
5 Stud
The tandem pump is a combined vacuum and oil scavenge pump. The scavenge pump is g-rotor type pump that drains oil
from the secondary turbocharger to accommodate vehicle tilt. The pump is located at the rear of the RH side cylinder head
and is driven from the exhaust camshaft.
Exhaust Manifolds
Each manifold has a connection for the EGR (exhaust gas recirculation) transfer pipe.
The engine is fitted with twin variable geometry turbochargers, which fix to the exhaust manifolds by a 3-hole flange with
a steel gasket.
LUBRICATION SYSTEM

4 Primary turbocharger
5 Crankshaft and connecting rods
6 Oil level and temperature sensor
7 Oil pan
8 Oil pump
9 Oil cooler and filter assembly
10 Piston cooling jets
11 Secondary turbocharger
Oil is drawn from the oil pan and pressurized by the oil pump. The output from the oil pump is then filtered and distributed
through internal oil passageways.
All moving parts are lubricated by pressure or splash oil. Pressurized oil is also provided for operation of the hydraulic
adjusters and the timing gear chain tensioners.
Oil returns to the oil pan under gravity. Large drain holes through the cylinder heads and cylinder block ensure the quick
return of the oil, reducing the volume of oil required and enabling an accurate check of the contents soon after the engine
stops.
System replenishment is through the oil filler cap on the RH camshaft cover.
The moulded composite oil pick-up is immersed in the oil reservoir to provide a supply to the oil pump during all normal
vehicle attitudes. A mesh screen in the inlet prevents debris from entering the oil system.
• NOTE: Fuel cooling is facilitated by a blast air fuel cooler in the return line to the fuel tank.
Oil Pump
ItemDescription
1 Oil pump
2 Bolt (10 off)
The oil pump is a gear type pump and is bolted and dowelled to the front of the cylinder block. It is sealed by means of a
rubber gasket, which is recessed into the oil pump housing. The pump inlet and outlet ports align with oil passages in the
stiffening frame.
The pumping element is an eccentric rotor, which is directly driven by flats on the crankshaft. An integral pressure relief
valve regulates pump outlet pressure at 4.5 bar (65.25 lb/in2).
The front crankshaft oil seal is housed in the oil pump casing and is fitted such that its front face is 1 mm (0.04 in) under
flush with the machined front face of the oil pump.
• NOTE: The seal is not to be pushed all the way into the bore as this will block the seal drains.
Due to the wide range of inclines Land Rover vehicles operate across, the geometry of the oil pan has been configured to
guarantee oil pick-up across all operating angles. An oil-scavenge system has been developed to guarantee excellent oil
flow through the turbochargers on severe side-slopes. Whilst the 60-degree cylinder bank angle of a V6 engine allows the
turbochargers to be packaged relatively higher in the vehicle, to obtain the best configuration for the V6 engine, the
turbochargers must be sited much lower. At extreme angles, there is a risk they may be below the oil level on the oil pan,
restricting oil return flow.
the oil pump to supply oil to the turbocharger bearings from the main oil reservoir (oil pan)
a secondary reservoir to receive oil from the turbocharger bearings
a tandem pump to urge oil to flow from the turbocharger bearings into the secondary reservoir and to pump the oil
back from the secondary reservoir to the primary reservoir (oil pan)
ItemDescription
1 Turbocharger oil feed pipe
2 Tandem pump
3 Oil evacuation tube
4 Turbocharger oil return pipe
5 Oil scavenge pipe
6 Oil pan
An additional feature of this system is that the tandem pump used to pump oil back from the secondary reservoir can also
be used as a source of vacuum for a vacuum operated system.
A semi-synthetic, low SAPS (sulphated ash, phosphorus and sulphur) oil is specified, which reduces the ash loading in the
DPF (diesel particulate filter). Ash cannot be burnt off like soot so it remains in the DPF for life. Without the use of low
SAPS oil, the DPF will not be a 'fit for life' component.
This low SAPS oil is also more resistant to temperature-related degradation than conventional mineral oil. It has lower
viscosity at low temperatures and improved lubrication performance at higher temperatures.
