Title: DW8 on veg?
Post by: Keef on April 07, 2021, 02:32:13 PM

Looking for a small van and XUDs are almost non existent these days but have come across a few with DW8 engine.


Do these run ok on straight veg and what are the chances of finding one with a bosch pump?


Is this Bosch or Lucas?

Top one is hard to see.
Bottom one looks like a bosch to me.  Look at that little triangle sided bolt head in a recess top right - classic Bosch VE.

The top one is Lucas, the other one is Bosch but from a turbo engine, looks to be a later 1.9td in a 406/xantia.

Thanks for the help guys. Steve the grease has given some advice on the other channel re fitting an XUD pump onto a DW8 so I might find a small van a bit easier with that option.

I did the same conversion as Steve (1.9td Bosch pump on a 2.1td) it's a big job and there's no official pump timing figgers so it's trial and error to get it close enough.
You'll need to find a fully mechanical pump though (think 405 not 406) as the cold start on the later ones is electric and on veg will cause problems.
But I covered around 90K with this combo but that was on bio not veg.
