Thread: So... I think I've had enough

ok,, 3.9 refers to a ( D1) GEMS engine,, 4L is a (D2) thor,, quite different
if anything its proven the other way around,, the standard 4L engines will fail,, and if you just replace gaskets,, they will just fail again..
The 4.6's out of the Thor RR are built with the best LR blocks,, any that didnt meet the quality requirement were made into 4L's,,,
thats not to say the RR4.6's were in any way bullet proof.... just built on a better quality block.


Springs to carry loads are always a compromise,, even if you do standardise on one loadout weight and buy springs to suit, you are literally stuck with that setup,,

D2's off road will go most places any other beam axle 4wd will.

Thanks Pedro for clearing up my 3.9 4.0 confusion.
I had thought that they were basically the same block and bore just the intake and injection were different.
Am I correct in thinking that the D2 a the BMW engine in it?

No the engine is all LR x bolt mains and all but the fuel injection on the D2 is BMW derived German Bosch Motronic (modified 8 series V8 BMW).

D2 is excellent off road with 4 wheel traction control and Centre Diff Lock (They didn't all have CDL).

CHEERS

the D2 V8's are OK.... 240k on a V8 and you will have a tired engine. carefull with this head gasket busines and it could well be slipped liners even if only minor and only leaking a little.

pull the plugs and see if you can detect any wash on the plugs or in the pots....easy enough with a probe and a lap top to have a poke inside the pots...its how i 95% diagnosed my D2 with slipped liners.....the last 5 % was when i pulled the heads and the gaskets were good.

i went down the path of top hats .... will cost between $800 and $1k on top of a normal rebuild depending on what you have done.

other wise the D2 is a landrover ........ a machine of unrealised potential.

if not done recently you can expect to do what is in a recent post of mine from a few days ago.

all good

Buy a 2006 facelift 4.2SC L322. If you like v8 petrols you will get a buz. Lots of other pluses too.

D2 base models are very simple and very reliable. Liner shift isn't all that common. Usually head gaskets. Easy fix and a long term one if you use ARP Head Studs too. Cheers

I'd like to stick with the Land Rover maque though because I'm a glutton for punishment. I've had an Series 1 Disco with a 3.5 V8 which I loved, but know every little about the Series 2 and 3.9/4.0 V8s.
I am considering a 2001 Discovery with around 240,000ks. So far I have found out that it has had both head gaskets done in 2016 (losing coolant not overheating) and it has been converted to springs.

What are the truck like off road?
How do they handle with the spring conversion?
Any major engine problems that I should be looking for? I understand that the 3.9/ 4.0 engines are far more reliable that the than a 4.6.

I'd appreciate any comments from others about there Disco experiences.

Cheers

If you are hoping that you will get a problem free run from an 18year old D2 that has already done 240k then you are dreaming my friend.
Having said that I bought my 2004 D2a 4 years ago for $9000 and have spent about $20,000 since on repairs and mods But I now DO have a reliable go anywhere and comfortable 4WD, It just depends on your level of commitment that will determine just how well your D2 will run

Trout illustrates my point about an upgrade. There are virtues to d2a. But I think go for a much more advanced (and complicated I admit but you’ve not got that far to go in NZ) series 2 L322.
