Hi guys
I'm looking at buying my first range rover and need some advise.
looking at something around 05-07 nothing too precious to take into battle on my daily commute lift a couple of inches throw on some A/T tyres and run through the winter. either a L322 or L320 ,my budget means that i'm looking at vehicles with 100K+ miles but reports of injector problems and cost of body off turbo replacement has put me off diesels .
So maybe a petrol with a lpg conversion ? I've read about valve wear and running problems with them. so Im back looking at diesels.
Help!
Is there a model that you would you guys recommend?
which of diesels need body off turbo replacement and are lpg conversions really that bad? is there a model that is more suited to conversion.

Thanks in advance
 
I know certain people will bitch at me for this . BUT the simple answer is choose the one YOU like and suits what you want it for. You're the one who will live with it not us.
They all have their issues , but different people like different things, so I might say Full Fat, others will say semi-skimmed.
Clear yourself some time, sit down and read through the forum. You'll soon get a feel for which problems bother you and which don't . Then you can make a more informed decision. There are loads of threads on comparing the different engines/lpg conversion/ lpg problems, etc, etc.
Just remember diesel is now the Devil, as far as the Government is concerned.

These should all be on air suspension. So can lift themselves. You can do things to make them run higher, but may not be needed. You will also want to consider what tyres and sizes you want to run.

Early L322's are BMW based with BMW infotainment. The Td6 is a bit under powered and has an under specced gearbox, so they all need rebuilding and will likely fail again because it is under specced. The BMW 4.4 V8 is a nice engine and I believe takes well to LPG. These early BMW models can run 18" alloys which gives you the most choice of AT tyres.

Latter L322's are Jaguar based with Jaguar infotainment. I believe both the BMW and Jaguar systems can be prone to issues with neither being particularly more reliable, but maybe the Jag based tech is a little ahead. The Jag based tech is more modern however. The Jaguar AJV8 is also 4.4 litres, but more powerful than the BMW unit and quicker. But I believe they are less keen on LPG, although it is possible. The L322 never got the TDV6, the only offering was the TDV8 when the BMW TD6 was replaced. The TDV8 is significantly more powerful, and would likely out perform the BMW 4.4 petrol, but with much better economy. However the TDV8 (3.6 litres) can throw up some significantly large bills if they do go wrong. But they are very nice to drive.

The Range Rover Sport (L320) is a completely different vehicle in terms of design and components vs the L322. They use completely different platforms/chassis. Arguably the L322 is more wafty than the RRS, but tbh I've never really understood why Land Rover built both side by side. They are pretty similar in a lot of regards. I think the rear seating is slightly better in the L322 and the interior may look a bit more plush. But the RRS is still a rather nice place to be. Really the main difference may come down to the L322 having a split rear tailgate while the RRS doesn't!!!

Engine wise, you get the same options as the latter L322 but also the inclusion of the 2.7 TDV6. This engine performs a lot better than the TD6, although there have been a few issues with snapped cranks, however I'm not sure if this is something to worry about or not, more research required.
 
Mine is 4.4 jag v8 petrol on lpg.
Many say they should have flashlube fitted but mine doesn't and is on almost 130k. (YMMV)
For me, it is the best compromise, diesel economy with petrol power and v8 soundtrack.
If I was buying a more expensive one instead of my tatty version, I would probably fit flashlube but as this one owes me nothing I'll leave it as it is.
The tdv6 is best avoided, as stated above the cranks snap on these with amazing regularity. (look in the jag forums, many snapped at low mileages)
The l320 is basically a discovery in a different frock so if I wanted to use it as a workhorse or off road, I would get the disco over the sport any day.
 
First thing to buy is a diagnostic kit, if your going to keep it long term then petrol, ppl are banning diesels from towns and city's now and it wont get any better
 
The AJV8 needs a flashlube system on LPG.

In my opinion as someone who fixes them regularly, i'd get a 2006+ V8 petrol.

The diesels are far to troublesome for me.

The early M62 has Vanos issues and the gearbox is carp/

Mines on 130k and according to the lpg ecu has done 95,000 km on lpg and still seems to be OK.
As I said, if it were a more expensive car, I'd invest in flashlube but this one is a van basically so it will be run until it dies.

With Flashlube fitted, it's probably as dirty as a diesel.

huh?

who mentioned dirty?

V8 Diesel is far too complicated and not that economical to warrant.

I know for a fact a L322 LPG with FL is cleaner than when on Petrol. and significantly better than its diesel counterpart.

Well, you and others keep mentioning that LPG is clean, but with flashlube it is not.
As sure as hell the emissions will be higher than a diesel with SCR and ADDBLUE.

It is cleaner the Flashlube is basically a lead replacement additive, and a cleaner.

By all accounts it does nothing to emissions it is listed by most manufacturers to "reduce" emissions.

We've had a Nissan 350z with LPG and a Flashlube system was fitted later on as it does track use, on the emissions machine.

The Output was no different with Flashlube.

Just a myth i'm afraid,

I've done 30k in it since I bought it and it appears fine, if it died tomorrow its paid for itself 10 times over and I'd find another one in better general condition and then I'd fit flashlube.
If it doesn't need too much for mot in January I might consider tidying it up and sorting a few niggles out and keep it another year, if I go down that route I'll probably fit flashlube and a more up to date lpg ecu.
 
Flash lube is a lead replacement and the later engines that run on unleaded fuel should not need it fitted as the valves seats are designed run without lead so flash lube is not necessary running on LPG
