I don't think any engine is 'best' but in the time ive owned my P38 and been a member of several LR forums, the 4.6 motor is always the one that overheats and ends up with a porous block/slipped liner.

I havent ever really seen any postings from people with the 4.0 engine complaining of the same thing. This doesn't mean the 4.0 is any better, it just means I haven't seen anyone complaining about it as much as I have re 4.6 engines.

I think you maybe had a bad experience with your first Range Rover. I would try again with another, if you are worried about engine overheating problems then maybe think about trying to find a higher mileage petrol one thats had problems already and had an engine replacement or had top hat liners installed. Or go for a 4.0 one with as higher spec as you can find.

I don't own the petrol version, I own the diesel but im sure some of the petrol guys will come along and correct me on anything if im wrong.

In this months issue of Car Mechanics (November) there is a very interesting article on the Range RoverP38 written by the editor Peter Simpson.The front cover shows a picture of a V reg P38 with head line
"Bargain Range Rovers" It's worth a read.
Good Luck.

Hi, My 4.0 litre had a liner shift. but it is very uncommon, its mainly the 4.6 which suffer from liners moving as the liners are very thin. I would personally stay well clear of DSE models. unless they have had a power chip upgrade, I have driven my brothers and they are really bad. i wanted to jump back into mine. my bro thought i was taking the mick, until he drove mine.

Best of luck in your search.

Just read that article on Range Rovers in car mechanics,it sounds like he rates them or he as got a job lot to sell,worth a read though. Thanks

Car mechanics is a good mag but i find they tend to spend way over on some of the project cars than you could pick a decent one up for.i suppose its down to you to work out the costs of getting a tidy v8 and having a decient lpg system fitted or spending the extra and buying the deisel

I have a '96 2.5 DSE, & it DID seem a bit sluggish unless well revved, stuck in a chip, it made a noticeable increase in performance, fuel consumption is better now as well.

4.0 and 4.6 are the same bore, it is only the stroke that is different, 4.0s DO suffer from the porous block syndrome believe me, you can get a 4.6 with top hat liners from "Turner Engineering" there new liners have O-rings which stop coolant loss and seems to be 100%, save up and get a L322 then you will never get the porous block syndrome.
