The N/A XUD was 'replaced' (sic) with the DW8 around this time.

If in real doubt, take pic (take others so owner does not wonder what you are doing) and post it here and we'll confirm for you for sure.

Oh gawd!

Long way to go to take some pictures, and there's no point in ringing the guy up to ask him which engine is in it, cus he definately won't know.

There's an older ZX TD estate for sale that the owner has confirmed runs on a Bosch pump.

Yes That WILL have a Bosch Pump, however, Check ZX's carefully. They can and DO rust.. Cills can be BAD and also the inner floor pan were it meets the front sub frame mounts... have a GOOD poke around!

Yes they are apparently galvanised, but this does not stop the ZX.. they DO RUST...

I can confirm that one

Now bodywork I can actually get my head around, so that shouldn't be too much of a problem for me, but I wasn't actually aware of rust problems in the ZX, and definately not in the areas you've mentioned.

As for the mechanicals, well, they're just something to do with black magic as far as I'm concerned.

Thanks for all your help guys. Mucho appreciated.

Bit off topic, but what's THAT all about in your signature?

Oh, and also, I note you have a Volcane running on veggie.How does it like it?

I've had two Volcane TD's over the years. Lovely car and would actually consider another one if I could find one.
Really wanted an estate, but I suppose I could manage with a hatch.

It runs pretty well on veggie actually, once it gets up to temperature I don't really notice much difference in performance. More smoke than usual and a little less fuel economy but can't complain given how much money it saves.
It's a touch lumpy to start especially when using high ratios of veggie to diesel in the cold mornings we've been having.

RE: my signature, you mean the bit about my old Pug right?
Is not as interesting as it sounds - some git from Folkestone stole it and dumped it on someone's private parking spot, the police found it and demanded I pay them for its return, which was more than I could afford for a car I didn't use. So I still had to pay them to scrap it.

There's no need to go anywhere

, ask them to take a pic of the engine bay and the pump (a general pic) then you post them here and we'll tell you.

Guess what?
You are right.
Typical.

Rang the guy up, and he whistled a mechanic over from next door to his pitch in Manchester.
Give the guy his due, he rang me back within 5 minutes to confirm it's fitted with a lucas pump, doh!

The search resumes relentlessly.

Oh.

You cannot fit a Bosch pump to a DW8, not without a lot of trouble as it never ever had one fitted.

Really not worth the effort trouble or expenxe is it?
The asking price was only £500.

Shame really, as it would have fitted the bill quite nicely.

Thanks for all the help and advice again anyway.
If it hadn't been for you lot and this forum, I'd probably and in total blissful ignorance, just gone up there, possibly purchased it and faced the dire consequences of feeding it veggie.

I never knew about this DW8 btw.
What were the main differences between it and the XUD to which I am familiar?

All DW8's are normally aspirated (no turbo) , XUD's came with or without turbo. XUD's are highly reliable being in effect a 70's design and made out of 'real' metal. With correct and regular servicing they will last, um well almost forever, certainly a long time.

About 10% less power and 10% less economy than the N/A XUD

, allegedly. To be fair emissions are a lot lower. It came out to meet a certain Euro standard which it did, but unfortunately another standard came out about 2005 which it did not meet, so that was the end of that. They all have a Lucas pump and EGR, although some of the later XUD's had EGR too. I've yet to work out how this "helps" properly on an indirect injection diesel as it likes to coke the inlet manifold. On a direct injection (HDi etc) then probably yes it does work.

Mechanically it is very similar, the blocks are almost the same as far as I know. The head is different, and the timing belt arrangement was changed from the nice automatic tensioner to a manual one along with adjustable pulleys for the cam / pump, again not a great idea. To be fair it discourages DIY which helps dealers I guess.

The DW8's have a plastic part cover over them like HDi rather than showing you the engine. Expert / Despatch vans with this engine do not have this cover usually. The smaller vans and the cars do.

Google for DW8 engine, then look at a few pics, then Google for XUD engine.

As you can tell I'm not a huge fan of the DW8 having had plenty of time with the XUD, the only advantage I can see with the DW8 is lower emissions, I cannot see any other advantage at all. Someone please correct me if I have missed something really obvious.

Wow Andy, that was some easy to read and understand explanation.
Most informative to a not very mechanically minded eejit. Tar.
