Simon_CSK Posted August 7, 2008 Share Posted August 7, 2008 Been thinking about a new toy and getting a 4.6 HSE with a Gas Conversion. Have extensive knowledge of Classics but know naff all about the P38 what should I be looking for and what should I be avoiding? Quote Link to comment Share on other sites More sharing options...
Coastcard Posted August 7, 2008 Share Posted August 7, 2008 Have extensive knowledge of Classics but know naff all about the P38 what should I be avoiding? P38's ! I am sure that there will be some people with more experience along, but from the little I know: 1) Engine - Bore liner issues (well documented). Gearbox ECU is also linked to Engine ECU, so upgrade to Megasquirt (or similar) not easy(/possible?) to improve mixture. 2) Air suspension - Similar to later Classics - perished bags, compressor and of course an ECU. 3) Electronics. Lots of them and all linked together in a Lucas stylee (i.e. not logical). Think the bodies and chassis held together a bit better than the classics. Like many people, I have only seen the bad bits commented on, but I am sure there must be some good bits. Try rangerovers.net for the full sp.

geoffbeaumont Posted August 8, 2008 Share Posted August 8, 2008 Okay, my knowledge of P38s is pretty limited, but from what I've seen of them: 1) Engine - Bore liner issues (well documented). Well documented, but appear to actually be quite rare. Gearbox ECU is also linked to Engine ECU, so upgrade to Megasquirt (or similar) not easy(/possible?) to improve mixture. Probably true? Ashcrofts could probably cast some light on the chances of getting the gearbox working without the original ECU. Replacing it with an earlier non-electronic gearbox, but overall it might end up making a lot more sense just having the original ECU reprogrammed if it needs it. Most P38as run quite happily as shipped though... Ignition is coil packs not distributor, so not moisture sensitive like the classic. 2) Air suspension - Similar to later Classics - perished bags, compressor and of course an ECU. And as with the classic perfectly straightforward to work on - plus much improved ride quality and road handling. Does still need reseting with a diagnostic computer if there's been a fault. 3) Electronics. Lots of them and all linked together in a Lucas stylee (i.e. not logical). Anecdotally at least, this does seem to be true. I'm pretty certain they talk to the ECU too, which is another strike against Megasquirting. Think the bodies and chassis held together a bit better than the classics. I've never seen a really rusty P38a, but I've seen a lot of basket case classics (even late ones not much older than the P38as)... They seem to be generally better put together too, doors that shut properly, that sort of luxury... Interiors are much more modern, they're much quieter and significantly less agricultural on the road (even the diesels). Parts were hard to get hold of second hand and aftermarket a few years ago, but that no longer seems to be the case - plenty getting broken now. www.rangerovers.net is USA biased but a good site - lots of info and many more P38a owners on there, so definitely worth a visit.

Escape Posted August 9, 2008 Share Posted August 9, 2008 I own 2 P38a, a diesel and a 4.6V8. The diesel has clocked 335.000 km without much problems, only normal wear and tear (alternator, bearings and yes, airbags). The V8 has 320.000 km but the engine was badly treated by the last owner and his mechanic, resulting in me doing a rebuild (very slowly coming, but confident the result will be worth the effort). I am very found of both cars, ride comfort is superbe and offroad performance astonishing for such a big car! Frankly, I think the Classic is better looking by a mile, but I'll stick to my P38a's because their so much nicer to drive (not that I have anything against driving a Classic off course!). One thing to consider, the P38a was state of the art when it was released, and consequently still a very complex vehicle today. With age, problems are bound to appear, but most can be fixed with common sense and DIY skills. Parts are often more expensive compared to Classic/Defender and fewer available at breakers. The EAS is a piece of art and (for me) the biggest plus of the P38a. But as it ages, it does need maintenance. Replacing the airbags is easy and so is a compressor rebuild. Replacing old O-rings can be a bit fiddly but definitely can make a big difference. Just stay away from official stealers, they'll charge an arm and a leg just to hook it up to a computer. Fortunately, a lot of software is becoming available and many independant mechanics (or even owners) now have the necessary equipment to clear faults.

roybatty666 Posted August 9, 2008 Share Posted August 9, 2008 Do it I have a 1996 4.6 HSE with 65k on the clock, drives like a dream, it is like going to work in your front room I have changed the bags and taken a bit of slack out of the steering box but that's it. As has been said they have something like 11 ecus in them and can have electrical issues. With the current economic and petrol situation you can get them for buttons!

q-rover Posted August 10, 2008 Share Posted August 10, 2008 Have had mine nearly 2 years, and other than upgrading from the previous owners lack of maintanance, or my own breakages whilst offroad, I have had no problems with the vehicle. The RangeRovers.net site is very usefull for info. Also consider getting your own diagnostics kit from Blackbox. I did and love being able to diagnose faults, change EAS heights, change settings within the BECM, read live data from the engine, etc. As for ECU's, yes they are all linked to the central BECM, so it would be difficult to get the engine to work with a stand alone system such as Megasquirt.

Thanks for the input guys. Was aware of the liner problem but un phased by it, my CSK had the same fault and I fixed it with cermic block sealer and it has been fine ever since. Also aware of air suspension but unaware of most other issues. Quote Link to comment Share on other sites More sharing options...

jemdh Posted August 19, 2008 Share Posted August 19, 2008 I have a '96 4.6 HSE which I love - very few problems as it's been well maintained (which is invariably the key). Coming up to 100 000km and I'm also considering an LPG conversion. Anyone know a reputable outfit in Portugal (or even Spain)? I live in Portugal and don't relish trekking all the way back to Blighty to have it done. Quote Link to comment Share on other sites More sharing options...
dan_uk_1984 Posted August 25, 2008 Share Posted August 25, 2008 I think the key is when you go to view one to make sure EVERYTHING works already, Air con, Mirrors, Heated Seats etc. Even if you may not use these they will detract from the value if you come to sell, and you should also be knocking off appropriate money. They are outstanding cars, the only problems I've had have been self inflicted. As mentioned earlia they are brilliant off road. If I didnt care about my body panels I really could go anywhere. If you like gadgets go for 98+ they have side air bags and I think the speed adjusted stereo & 4 wheel ETC rather than the early ones with only rear wheel ETC.
