DIIs and their V8s....

[nzoliver]

Aloha all from the sunny south pacific!! 

Er, has anyone on 'ere (or who have friends that) have had issues with the 4.0l V8 in the DII?   8-[
I am looking at swapping to my DII V8 and selling my '98 Tdi is all. It has had to have a head gasket but that's hardly a major compared with slipped liners on the V8. The question is..how often do the V8 ACTUALLY go bad?  :-k

Thank you all in anticipation...  :clap:

I've NEVER seen one, but I've heard all the stories.  TBH it does happen but RPI reckon that it follows about 3 serious overheating problems, so there's the fist thing to check, hasa it ever or does it get too hot.

Slipped liners occur because the liners weren't pushed down to the register so when the casting relaxes or cracks they can then slip down by a small amount leaving a gap between liner and gasket, the relaxed casting then lets water in between itself and the liner and up over the top.  Typically only when you turn off to start with, the compressin keeps the water at bay otherwise.

First sign is a car that uses a tiny amount of water each cold start, starts lumpy perhaps with condensation and one very clean plug/piston.

The 4.0 should be a cross bolted engine so better suited to running hotter and reving higher than the earlier EFi engines, the V8 runs best well below the 80 degrees favoured by the Lucas EFi system on the D1 and RRC.

Good servicing and a heating system in good nick, including the viscous fan.  Any mods or alterations other than new parts need thorough explanation, eg electric fans mean it overheats.

Thanks for the input.  :D
There seem to be a LOT of the V8s out there but they can't all fail.


This is my dilema..
The last DII V8 I had gave me 16-18mpg.  :shock: But that said, I only get 22-24mpg from my Tdi. All of them have been the same mpg wise. We think it is something to do with the fuel we have. 
Our diesel is still priced without road tax but that costs me about 4c /km. Diesel costs $1.12 a litre here. My PDA software tells me that is @.17c/km on average including road tax. High octane (95) petrol is $1.42/l. At 18mpg (19l/100km) petrol costs .25c/km.
Looking at that it is a no brainer!!  But diesels cost more to service and repair - well they do here. 5000km service vs 10000km for the petrol. That brings the difference down to about 4-5c/km more for the petrol.
Tough decision!! The DII is very nice...  :lol:

porus liners was another problem,but to help that mate,never use bluecol anti freeze,it eats alloy :-k

Do you get LPG conversion in NZ? over here I get 27-29mpg out of a 300 TDi and about 12.8 MPG out of my LSE, but that's on LPG which is now just over half the price of diesel, making it 25.6 MPG equivelant.

If I need to go somewhere in a hurry, or just put a smile on my face I take the LSE :D

[nzoliver]

Howdy,
Yep there are LPG conversions 'ere. :P
Multipoint is just kicking off and I would look at importing a kit (- the tank as the UK ones are not NZ compliant - we have tougher specs I believe). I would also look at buliding a petrol tank half the size of the existing one so I can use the existing pump etc and bolt a 'bomb' under there as well.  :-k

I do have a soft spot for my Tdi tho..... :doh:

My LSE is multipoint, I notice no difference to petrol.  That said it usually runs out of tarmac before I can eally open it up :twisted:

If your tank regs are tougher than ours, crikey :-. they should be safe.  Personally I don't like the idea of a petrol tank in the rear corner outside the chassis, asking for someone to hit it.  However I know you will have a problem fitting a big tank, mine goes in the spare wheel well.

Hey, why not buy a RRC :D

As for TDi vs V8 I think a lot of it is go for what you know, either makes a good truck.
