wot are the 4.4s like wen there on gas anyone no

any 1 plz

wot u got then?gas system? i take it its 4,4 V8 petrol

nwt yet just wonderin how they coped with it yes 4.4 v8

Personal experience of V8 gas was ok however you got to do alot of miles to make it pay,then there is the engine wear to consider.It will be a bit hotter.

Id sell it and get a diesel if you feel the need.Otherwise its a V8 rangie so live with the fuel bill.

The 4.4 is not an easy engine to feed LPG to properly,find a company who will let you try a customers converted car and talk to the owner.It is a very quick revving engine which the gas systems find difficult to keep up with.(Plus its not easy to plumb in the coolant pipes to the vaporisers.)

any 1 on ere got 1 or done it

nope cos no one has been stupid enough to try yet,go for it.

BEWARNED it WILL cook your engine in 50k miles.

will it

could do

if the gas system is set up correctly on any engine and is kept in good condition then there is very little risk, there are horror stories with lpg but to be honest most can be put down to poor setup/ maintenance.

valve recession, burnt valves, blown head gaskets etc etc are what people blame on lpg. my own engine cooked, and i was told as i was face deep in v8 madness pulling bits of engine out from under the bonnet even carlesberg couldnt explain,
'bet its on lpg mate'
'yes' i confirmed
'arr, it does that to these engines, runs em too hot'
to which i replied in a condescending manner:

'the problem with these engines is the fact that bieng a very old american design they were outdated even before the very first one made it into a lr car, this however didn't worry land rover, neither did the fact that the original design was iron blocked and LR decided to save weight they would use aluminium with a ductile iron liner, the two metals expanding and contracting at different rates and the early engines 'wobbly block' characteristics meant they were close to thier destruction point even at thier designed performance rate. any change in circumstances could and often would split the aliminium block/head causing failure. more so if the engine ran too hot'

which confirmed his point enough to repeat:'lpg does that'

'but the moron who owned the car previously used garden hose on one of the water pipes which disintegrated and resulting overheat allowed the liner and block to part company, the fuel was irrelevant in this case. even running on petrol this would have still happened!!!'

'know your engines then mate dont ya' was his complement, it could have been just and outburst for all i know.

in my annoyance i insulted him thus:

'no mate, i just posses the ability to read and form a logical picture of what is going on from that reading'

after that he just sort of trailed off to look at scrap cars in the yard, no doubt wondering if this reading i was talking about is just for other peple!!

you have a point gav

I would pop in a merc V8 for gas as the engines are far newer and design is more tollerant to gas.

yeah i have one . its brill . you need a multi point injection system , get some one who is a registered gas installer and you will have no prob , if you do a lot af miles OK ,if not its hardly worth it as a couple of grand buys a lot of petrol , ive had no faults with the gas a HMVL system .

HMVL?? do you mean OMVL??

I've got a gas converted L322 its done 93k and it runs fine! its more powerful on petrol as you would expect but it's nice and cheap to run compared. I'd say go for it providing the conversions done right.

There's the thing you see - people expect less performance on LPG.If your car has a decent system and ITS SET UP CORRECTLY,you should not be able to tell the difference.The motronic engine management can use its adaptive ignition and knock sensors to run enough advance to benefit from the higher octane rating of the LPG.
This was the main problem with LPG on engines with distributors,the timing was always compromised,even with the aftermarket advancers that switched in on LPG.(They do help a great deal tho.)
I've even seen engines with the timing set at a 1/2 way setting between the optimum advance for petrol AND LPG - so its not right on either.

i notice a bit of sluggishness, but not a deal, on petrol it is punchier but its and old single point lpg kit and you cant expect too much from basic kit!

that said it performs well and its only experience that makes me notice the difference. in most ways there is no difference,

the newer more advanced kits (are we on gen 5 nowadays???) are built on the experience of the years that lpg has been mainstream and, as in any sector, the lpg industriy has made changes and improvement!!

i'd say go for it, it will cost to get it installed, it will cost to service it but that cost is certainly recoverable via the decreased running costs.

i also noted the oil in my rangey's old engine was just slightly muckier than when it comes out of the tin!!! the new engine(second hand) had oil in that was loppy black and brown stains all over the valley where the lifters are and crank case. the old engine was clean and just a few nooks and crannies had stains!!!

dunno what all that means but i assume the lpg engine doesnt degrade the oil as quick!!!

I pulled out oil 2 years old and it was clean as.......

Very little darkness.still looked like new really....

Just bought a 4.4 Vogue Petrol with LPG conversion. Its done 100k but wont run on LPG at moment, as strong smell of gas and starts bunny hopping, its booked in for tomorrow!
