The old v8 4.6 engines are good for lpg conversions, gems or thor. Lpg doesn't cause any real problems the valve seats are all ready hardend so no reported issues of valve seat recession.

The jag v8 4.2 engine however has known issues when converted to run lpg they have soft valve seats that burn out on lpg and are sometimes known todo it on just petrol alone. Even when fitted with valve lube a rrs forum member reported valve seat recession and a wrecked engine.

I have compression tested the engine in this new to me car and its slightly down on compression on 1 cylinder but within spec for now. The lpg is not going to be used much at all if any as my milage per year is low and as mentioned my L322 4.4 petrol will hopefully get ulez exemption if it does that will be our daily driver for the wife to replace her tdv6 D3 which cannot get ulez approval.

Iv not checked on the reg doc to see if the sport has been registered bi fuel or not as in standard form the 4.2 engine is ulez......mad I know at just 9.6 mpg around town if pushed but iv seen 26ish mpg on a run.

Currently showing 13.6 mpg and iv been sorting it since I got it with a few issues just the supercharger snout bearings to replace and lower control arms both sides then it's pretty much a sorted car......holds breath ..:rolleyes:

ulez madness, ban economical older vehicles and allow gas guzzling monsters.
 
I'm very late to this thread as I have only just seen it.
Having had 2 LPG cars I am really disappointed at its demise. They were petrol saloons and ran without fault for years on gas.
My local converter and supplier of gas has completely stopped all work on LPG and gone back to service and MOT work. Around Cheltenham the big boys have stopped selling it and all my old suppliers have long disappeared. When the 15 year tank and supply inspection becomes due, they just rip out or seal the tanks.
Having driven abroad, there are loads of suppliers but for how long? Its a lost opportunity in this country.
I'm sure if I reload the LPG app there will be far fewer suppliers now making it unviable as a regular fuel.
 
Here are the photos of the lpg set with the electronic flash lube set up

The flash lube is split to feed both banks its electronic and controlled by the ecu. You cannot just install a bottle and feed pipes there is no cause to suck the fluid in its needs to be pumped
 
There could also be a problem with servicing, some garages won't touch it if it has LPG, sommat to do with the fuel lines etc
 
When I was looking to buy one, there were quite a few LPG for sale. I contacted my local guy, who said he couldn't do it for health and safety regulations
in regard to LPG vehicles, apparently you need a special qualification to do them, it could be get out clause, can't be arsed etc.

It tends to be in the way. There isn't much of an issue as there will only be a dribble in the pipes.
 
On balance, I’ve decided to leave it for now… I’ve just found I’ve more pressing expenses on the old girl to attend to.

The impending scarcity of the gas and the upfront expense being the main concerns.

Thanks again for all the insight :)
