Tdv8 on lpg? It's a diesel.
I assume you mean the v8 4.4 petrol which was available as the BMW or jag engine.
Tdv8 available in 3.6 or 4.4
BMW petrol available in 4.4
Jag ajv8 petrol available in 4.4 n/a, 4.2 s/c and 5.0 s/c
I think that's all the permutations in the l322, not sure about the l405 engine line-up

Many thks , indeed meant the petrol

Also grateful for the info as funny enough was just looking on wiki of options

May i ask out of the diesels please is the 3.6 TDV8 a good engine plse

Or would u consider the 4.4 petrol on lpg better

Hope to one day get myself a rangie , not for a while yet though, hopefully being able to work on a D3 I’m hoping I can work on a rangie

Would be a 2007 onwards so can get the Zf gearbox

But will have to look into it over the next few years to ensure I know the pros and cons

Thks again and hope u didn’t mind me asking

My opinion on the early tdv8 (3.6) is that generally speaking they are lower spec (not always so you might get lucky) than the petrol. Both the 3.6 and 4.4 tdv8 are good engines but more expensive to run than a 4.4 petrol on lpg.
If you're going for the petrol get a post 2005 with the ajv8, you will probably want to put flashlube on it if you fit lpg although the jury is out on whether its really necessary.
All l322 apart from the td6 are zf gearboxes but the jag engined ones have the 6 speed which is plenty and arguably a better box than the 5 speed.
If you can run to a 4.2s/c great but they're thirsty and the 4.4n/a is plenty powerful enough.

Hope it’s ok @Wazzajnr to make a new thread, felt guilty of hi jacking someone’s thread , many thks

I only do around max 2,000 miles per year and the way emissions are going think a petrol would be nice

Really like the ZF 6 x speed I have in the D3

Think my D3 is group 33 so that’s another factor

Also maintenance, cost of parts , assume there around the same costings as a D3

If they have belts , cost of having a LPG system added etc

Always like to take a lot of time investigating the pros and cons

Ref the LPG , have heard being mentioned about an oil cooler or pump that is suppose to help the LPG , will try and find the correct terminology

Really do think my next landy will be a rangie , petrol on LPG , 2007 onwards , auto and in black

Thks so much and thought starting this thread may be ideal for others who are also thinking of getting an L322 and don’t know of all the engine / gearbox options and at least having a thread with all the info in one place will be a good reference inc all tech details inc replies from other members etc

Will have a good read of ur replies

As always most appreciated and thk u

The 4.4 petrol on LPG sounds good , apologises what’s the AJV8 please , is that just the name of the engine plse , thks

So the 4.4 lpg sounds an ideal options

Have heard about Oiler’s for LPG , have like a container on top of the engine that helps maintain the LPG

Many this

Ajv8 is the code for the jaguar v8 petrol engine. In my opinion it is a better engine than the BMW unit.
Lots of them about in black so shouldn't be a problem.
Obviously, if you lpg it, you either loose the spare wheel well or a chunk of your boot space. You also don't get 7 seats in the range rover.
I think oilers are just the flashlube system.
At 2k miles a year, I think you would have a hard time justifying fitting lpg unless you do it yourself.
On petrol, mine does 22mpg on a run and about 17 around town. Fully installed system is going to be in the region of 3k but there's plenty for sale that are already converted so stick out for the right one.

Thks for the info

Definitely room for thought ref the LPG systems and would indeed buy one with it already fitted

Suppose in the same token there’s good and bad LPG systems

Apologises keep asking questions, are there a particular brand of LPG to go for plse

Would be weird servicing a petrol again after having diesel for some many years

Just been searching ref the jag engine of what normally u need to look out for

Thks so much once again

My lpg is acon agis obd/can ecu with a mixture of other bits fitted. It's not been installed very well and I'm working my way through sorting it out as time permits. Ecu hasn't been linked into the canbus but will be soon and this helps keep the fuel trims correct. I think they are all much of a muchness but you need to make sure the vaporiser and injectors are the correct size.

Many thks , looking on auto trader there does seem quite a few that’s already been converted as u also mentioned earlier

Will also have a look of what the ins groups are

Ref AJV8 and LPG....Flashlube is a must on the AJV8 engine to prevent valve seat regression.

As for makes: Prins, BRC, OMVL are all very good....

I'm going to fit it to mine just to be sure but it has done 4000 hours on lpg since it was fitted and 800 hours on petrol and seems to be fine so far.
I wonder if the horror stories of valve seat recession are more apparent on the supercharged ones?

Ur a legend , thk u so much

Will also be very handy for others who ask the question

Thread is certainly getting some excellent information that’s for sure

Of course @gstuart if you go for diesel you can just pull in to any petrol station fill up and go plus no extra ecu`s to worry about but thats just me, did think about petrol and lpg when I bought the p38 12 years ago but by the time added up the cost of conversion and under slung tanks (needed to get the range when we go to see family) plus lot of my running is short 1 and half to 2 miles trips most of the time it wold have been on petrol so it didnt make sense.

That Jag engine is gorgeous. Gets my vote. Only issue is a pipe between the v that goes but never had an issue on my 4L. @Henry_b knows the details.

The AJv8 is arguably the best engine ever fitted to the Range Rover. ever.

The Valley pipe is under the intake manifold that joins at both ends via a pipe, it's common for it to split.

When it does you lose most of your coolant in a matter of seconds and it is pretty evident, the bad part is it can be fine one second and in meltdown the next.

On the N/A AJ41 it is a 45min job to replace.

On the S/C it's a 4hr minimum job to do, as the supercharger and ancilliaries have to be stripped off.
This one I caught in the nick of time!!!!



The AJ engine is very strong and that's it's only real issue.

It's also paired to a ZF6hp26 which is a very strong box when maintained, link in my sig.

Many thks , also didn’t realise they fitted the AJ V8 into the discovery 3

Suppose with the way emissions are going that’s way I thought my next landy would be a petrol

So indeed would like to get the 4.4 V8 on LPG or because I do low mileage might get one without the LPG

Also see there’s the 4.2 petrol SC engine , but from what everyone is saying the jag engine is the one to get

Also confusing as it lists an AJ41

The 4.4 L; 268.1 cu in (4,394 cc) AJ41 version features an 88 mm × 90.3 mm (3.46 in × 3.56 in) bore and stroke. This engine also replaced the BMW M62 engine used in 2003-2005 Range Rover models.

Applications:

• 2005-2009 Land Rover Discovery 3 / LR3 - 300 hp (224 kW; 304 PS), 315 lb⋅ft (427 N⋅m)
• 2006-2009 Land Rover Range Rover Sport - 300 hp (224 kW; 304 PS) at 5,500 rpm, 315 lb⋅ft (427 N⋅m) at 4,000 rpm
• 2006-2009 Land Rover Range Rover - 305 hp (227 kW; 309 PS) at 5,750 rpm, 325 lb⋅ft (441 N⋅m) at 4,000 rpm

The Jag engine can be N/A or S/C in the L322.

I'd go for the N/A personally

S/C is a 4.2
N/A is a 4.4

Many thks

Daft question are they timing belts or chains plse , assume they need spark plugs etc changed every year as part of maintenance , do they still have rotor arms or is it all electronic now , can tell I’m behind, lol

So what is the AJ41 engine plse

Thks as always

Spark plug service for the AJv8 is every few years the exact time escapes me, my 3.0 S type specifies 100k service interval for the Plugs so thats probably the same for the AJV8.

They have Timing Chains, very beefy compaired to the M62

Oh and it's coil on plug ignition no dizzys or rotor arms

The ignition system is reliable, just watch out for the odd coil as they can fault

The AJ41 is a Bored/Stroked version of the 4.2 which in turn is stroked version of the 4.0 which was a bored and stroked version of the 3.2! got that? good. it is very robust in its design and is well proven

They also have VVT which is lightyears ahead of Vanos in it's durability!! .

With versions of this engine putting out 600hp at santa pod with a twin scroll charger and NOS

Did i say they're good motors?

The S/C has forged internals which is good for POWAH!!

But the Cast internals of the N/A are plenty beefy

On a slightly separate note.

Check for corrosion around the rear seatbelt mounting area and rear subframe the L322's are getting to an age and the tin worn has managed to sink it's teeth!!!

They rust!!

Check 'em properly alot can hind under a shiny exterior

Bless u as always for the great info

So this is the engine to go for in its 4.4 petrol form

Is the TDV8 diesel also a good engine plse , see that’s a ford engine though

The 4.4 and 4.2 are good motors.

The 4.2 is supercharged and slightly thirstier and slightly more complex, I'd have it if i could stomach the Fuel bill

The 4.4 is very spritely and simpler and the one i'd go for!

The Lion TDv8 is ok.

But like the TDv6 it eats turbos and EGR's.
And recently among higher mileage examples Headgaskets and Various seals are showing signs of failure so beware.

The TDv8 will do 22-25mpg compared to the Petrol which will do 18-20 so IMHO it's not worth it..

Best stay with the Petrol!!
