Keep the V8 or get a 300Tdi??
davidlandy:
I would still say for reliability go for the diesel over the v8 lpg. Its a proper factory made solution , not an aftermarket bolt on bit. Seen many lpg kits not working properly.
Also you have to watch out these days for the quality of the gas, there is a lot of foreign muck out there that can damage your engine if useed over a long period. I know this from experience as via work we used to run lpg foden tractors - their cat engines were failing due to excess wear within 300,000kms which on a truck engine is very,very low.

which makes me wonder why the 3.6 v8 diesel iceburg one at gaydon i mean from the late 70s never made it into production. 8-[

the iceberg engine was dropped due to production costs and production space.the engine had reached the production stage when all satalite assembly was closed down which ment more space and a new pruction shed needed at solihul all at the usual time when no extra outlay was available.
J E engineering were happy as the crackshafts from the iceberg engine helped them produce their new 3.9 and 4.2 engines before LandRover

I've been watching this thread with interest. I started my LR "career" with a TD (19J) 110, then moved onto a gassed 3.5 L V8 and sold that over the summer to be replaced with a 300 Tdi disco. I thought about buying a V8 disco but decided against due to fuel costs and some of the issues below.
So, a couple of comments from my own experience:-
- the LPG set-up on my old 110 was done by the previous owner who was a registered gas fitter (it was allowed in those days). I think it was a single point system and I added an electronic ignition. I had nothing but trouble keeping the LPG and petrol systems consistently running well together. I'd take it to the specialist and within weeks one of them would be causing trouble (I think a carb overhaul might have been in order). A multipoint system installed by a specialist may well give a better system. I reckon I was getting about 12 mpg on petrol and maybe 10 on gas.
- different people's V8's seem to react diffferently to water. Mine started coughing if we got within 100 metres. I tried the glove thing which did not seem to help much - and disintegrated within 6 months (£30 not well spent) and motercycle chain wax was not much better. Now I listen to my Tdi and think "that's the noise of reliability and a decent mpg".
- in years gone by I've been involved in these discussion and waxed lyrical about how the V8 sounded but at the end of the day the a LR is functional vehicle and not a performance one. My Disco is an automatic!! If I win the lotto I'll buy a petrol RR or an Aston martin but I think all my LR's from now on will be diesel.
- I know I have the option of sticking veg oil in which will improve the running costs even further.
A question: why are there some many 50th anniversary V8 in for sale?????
Just some personal thoughts.

50th v8 90 very nice but still silly money to buy.
as for condition diesel are always gonna have a hard life compared to the v8 (garage sales man words there) . most highest specd motor are always gonna be a v8 and not a diesel

Due to travelling more miles, should i spend £1200 on a gas conversion, or sell up and put it towards a diesel? - (correct me if i`m wrong)
personally i would think hard, i`m currently facing a decision, theres a nice v8 with the gas conversion coming up for sale soon, but for me, its a case of is it worth hanging on to the vehicle i know (+ mods) and now trust over the chance on a new one?
cost of fuel is 50/50, gas/veg oil 50pish, petrol cheaper than diesel, but you get a few more miles out of a derv... if your going for a diesel, i`d definatley look for a 200tdi, strong engine, (check gearbox over though!) and cheap as chips as everyone prefers the look of the 300 front end... but i spend more time under or in mine so front end looks are irrelevant really... this wil leave a bit in the kitty for those things that you are bound to get with a new car.. the wear and tear items that didnt look too bad when you first looked at it.. the a frame ball joint, the other "irritating rather than urgent" jobs...
but then theres the route of better the devil you know... i assume yours is in overall good condition? i would love the gurgle of a v8, but prefer the simple nature of a derv, performance wise, its adequate, its a 4x4, not a track car!

Mine is in reasonable nick, its had the boot floor done but i think the rear crossmember will need doing and possibly the n/s front inner wheel arch. Probably not to much drama for someone who knows what they are doing but not that econimical to do if I have to pay someone. At least I know what to look for in the next one........
RRB - i didn't realise that LPG systems are only £500 but I am not in the slightest bit able when it comes to mechanical things so I would have to pay for somebody to fit it.
I have been out today in it and love the V8 sound and will be sorry to see it go but i think i will advertise it for sale while it still has 5 months MOT and see what happens. If I can get £500ish for it then I think I will go the derv route
Thanks to everyone for their thoughts on this, much appreciated. I'll let you know what happens!!!
