Yep VW LT van engine, also used in some military personnel carriers too
As for the chip fat, de-water it using heat, petrol, or both. Adding a small amount of petrol helps the oil burn. Filter it accordingly, and then enjoy the smell of fuel at almost 1/12th the cost of diesel totally tax free!

Always wanted an old Volvo estate to run on veg oil, my parents run it in there mercedes 2.9 5 cylinder diesel engined Ssangyong and I have run it in a 1999 Polo 6N (which died as it had the weaker Lucas injection pump) and a Peugeot 405 TD with the XUD 1.9 engine with a Bosch pump! Although eventually my turbo seals went and it ran away dieseled until it blew up Sad times!

A small update, been running a sort of 70% mix of veg oil with diesel, and the pump doesn't like it very much. Done almost 1500 miles since getting home already, ferrying car parts up and down the country, and buying chip fat. Its pretty ticky and clattery on the veg, I'd imagine the small amount of petrol in the mix to thin the oil is causing some pinking, the nice quality of oil I have probably only needs a dash as opposed to the 5-8% I'm using. I think the problem is mostly me, being used to modern petrol injected cars over the last few years, and indeed still switching between them and the Volvo. The vac gauge I have in the dash probably isn't helping either, have noticed the readings fluctuating/dropping every few seconds before coming back up, so may try my spare vacuum pump to see if its the problem. Any sort of ticking noises like the ones this old diesel makes set the alarm bells ringing usually, I think I just need to stop caring as much and just sort of "meh" a bit more unless I hear anything horrendous out of the blue.
Anyone got a spare D24t engine or fuel pump going?
Had a bit of an oopsie as well, several of the little rubber balance thingy lines between the injectors decided to gracefully vanish into thin air, or crumble. Noticed on a trip to Birmingham, that my MPG was into single figures, then I noticed my rear window was covered in what I though was un-burnt fuel from the exhaust, so naturally I went to tone down the retard screw on the pump. At this point I realised that the entire engine and bay was covered in chip fat a-la-diesel. Looked underneath the car to find that the car had decided to begin the process of rust prevention for the winter months at the low low price of just £40 worth of my lovely fuel, which with my mix is nearly two tanks full...
Shall be running a heat exchanger, and I'll be investing in a few extra bits to convert to a twin tank setup over the coming weeks to start the car on diesel, and possibly a small auxiliary fuel pump in line with the tank to aid with the goopy chip fat making its way all the way from the back of this enormous vehicle. Hopefully this calms down the noises a bit. Also going to fit some new rear speakers, as the drivers side one isn't working, and the passenger sounds not dissimilar to playing farts through a set of pound shop walkie talkies. Don't ask me how I know what that sounds like, just understand that although I may look like an adult, but that I am not.
The speakers should also help with calming down the pump noise.

This is interesting, how fine are you filtering your WVO? I ran SVO mainly (clean unused veg oil) and if anything my injectors and pump were noticeably quieter! Loud injector knock would indicate a lack of fuel to the injectors or incorrect injection timing, perhaps you should retard your injection pump timing a little?
Also remember there are corrosive properties in veg oil, especially used stuff, which likes to break down rubber, so keep an eye on your fuel filters and be prepared to replace your tank to engine fuel line if it is made of rubber!
Hope this helps!
Mike.
*Edit; FYI I was running around full veg oil with a litre or so of petrol per tank to keep things viscous!

filtering to 5 micron, and filtering cold so it's far finer than the fuel filter. the ticking is more at lower rpm's, at 3000 is makes a diesel pinking sound when under almost no load at all. at full throttle it sounds fine. I may get the timing re-done, and in fact all of the belts, but I don't know of a VW/Diesel specialist down here in hampshire that would have the correct tools to do it, I certainly don't!

The Bosch VE pump should run fine on oil filtered to 5 microns. I would check the timing to be safe. Old diesel engines are fairly loud in general and a low rpm lifter tick is fairly normal. I am guessing at around 3,000rpm the noise you are referring to is injector knock? A friend of mine had this with his polo 1.9D ever since the injector pump had been replaced with a second hand unit after the original failed, we put it down the not getting the injection timing spot on, never seemed to affect performance. How is it smoke wise under load?
Also just thinking, we managed to make the injector knock noticeably quieter by fitting an after-market high flow in-line fuel filter rather than the finicky one VW fitted as standard!
Hope this helps,
Mike.

I can't just check the timing though, I don't have the specialist tools needed to do so.

I'm happy to do the timing + belts etc if you like. Have experience with these engines (fitted a '95 d24ticegr in my 740 and have a d5252t in a v70 too) and required tools. be a darn sight cheaper than a specialist (you cover the tea costs) and mines still running so I guess I must be doing something right. Down side is I'm a couple of hours away at the moment but running veg that shouldn't be a problem?

Might as well do mine if we're going that far. I'll be wanting this all done in the new year for sure, I'll buy all the bits and bobs. Don't mind driving, I can always sleep in the boot or something if there's an issue but with two pairs of hands I'd imagine we'll be alright. PM me!

tip for you, get the leakoff pipe from a pug/citroen dealer, under a tenner for a metre length unlike the £32 bmw wanted for the same hose!!
reason I say to use the o.e stuff is that it is 3mm I.d, and nice strong stuff, anything I have come across aftermarket has been 1/8"th of an inch, which is 3.2mm, bloody useless basically! not a tight enough fit, and also like most fuel hose these days just doesn't bloody last!

oh and its from any xud engine! they predominantly used bosch injectors like vw did, or lucas with the same essential dimensions.

Halfrauds actually sells it for £9 for a meter of it if I recall correctly! thanks for the tip on the size though, I did notice the vac line bodge I used was sort of loose!

Hope this all gets sorted and it runs well for you! Would love an old diesel Volvo myself! I have had a few but they were all petrol.

How are you de watering your oil? I would be concerned if it was noisier on special brew than straight diesel as everything I've run on it has been quieter. Are you letting your oil sit for a few weeks for the heavy ends to drop out in the cubies before filtering the top? You can check for water content by dropping a sample.of your oil into a red hot pan - spitting and hissing means there is water in there.

its quieter on straight diesel, noisier on veg. I'm dewatering with petrol and settling for two weeks - hot pan test shows next to no water. I skim the top off the cans of oil after a week of settling .

How are you dewatering with petrol? Also is it noisier if you run it on new veg with no petrol in the mix

Petrol takes the water out and settles it at the bottom of the tank, I leave it a few weeks. its a common method, its about 3-5% petrol. its noisier with more petrol, quieter with a low percentage. I think the veg oil might be igniting, with out without petrol, sooner in the combustion chamber than diesel. I have a bit of diesel in it at the moment and although the pump is still quite noisy, the engine doesn't make the injector knock/pinking sound

Really? Can't get my head round that, I used to heat and hold it at 60/80 degrees or so to dewater. Water and petrol don't mix from my experience stripping down carbs to remove blobs of water blocking the jets. I would guess its the % petrol that is making it noisy, veg oil burns slower than pump diesel retarding the ignition timing, (leading to a quieter engine at the same time) hence many people recommending advancing the timing slightly when running on veg.
