After selling my P38 a while ago I'm in the market for a L322 V8 Range Rover, (which I hope either has or I will later LPG). After doing lots of reading and searches it points me towards the BMW engine, but it must be facelift so narrows the search to a 2005 (or some 54 plates).

I'm finding it very difficult to find a good one in that narrow a search margin, with FSH, condition, mileage etc so is the Jaguar engine really that bad for LPG to avoid it completely or is it more down to installation?

I'm happy to wait for the right 2005 but if the 2006/Jag engines are 'ok' then I could widen my search!

Plenty of problems with the AJ Jag engine even without LPG. A TdV8 is better.

I understand the Jag engine is full of problems....I was lucky with my BMW engine but also understand loads of people wanted it because it was a BMW v8 and not the Jag.

Keep your search to BMW v8 would be my advise.

best of luck.

the Jag Engine doesn't convert to LPG very well...it is not a setup issue or poor install issue...it is mainly due to the dry nature of LPG doesn't keep the valve seats cool and lubricated, and they start to burn out.

A flash lube system can help as this 'injects' an oil into the intake to keep the valve seats 'wet' and cool but this has only met with limited success.

The Rover V8 and the BMW V8 converts nicely....if you want a facelift model, either spend more and get a TDV8 (and their associated problems) or get a 2002-2005 BMW Unit and do a facelift conversion (ala 2.0_Hippo).

Do more research on the AJV8 Jag engine, but with the number of reports that LPG conversions have wrecked the engine leads me to suspect, they are poor candidates.

I'll stick to the BMW engine then....not a problem but there is a lack of nice ones around. I will have to bide my time and wait for the right one to come up.

I know your son has been unlucky with one, and a batch did have big-end problems (like any manufacturer) but I've had three AJV8 powered cars which I thrashed over many thousands of miles without fault - the last one I sold at 170K miles having put 120K on it myself and the guy who bought it is still driving it at 230K miles having had no issues - my brother has had two similarly reliable AJV8 powered cars. I know a Jag tech who says they are pretty good in the big scheme of things - generally very reliable. I get that they don't like LPG but early camchain tensioner and nikasil problems (like BMW) aside the AJV8 has been a very good engine.

Looking at some of the forums, sadly, it appears that rather than the ocassional bad un, it's more of a case of the ocassional good un
