Volvo V70 DIESAILS Tell me MOAR.

[Lankytim]

Hi shits,

 

There's a cheap one of the above floating around FB at a decent price, but are they any good? This one is an R reg manual and quite leggy at 197k but it looks OK in the small pics I've seen of it. 

 

Do they run on VEGOIL? The equivalent Audis with the same engine apparently run OK but these Volvos have a bit of a question mark hanging over them for some reason. 

 

NEED INPUT.... The XM will be a very tough act to follow!

[Minimad5]

R reg, does that make it the early VW TD engine ?

 

If so, good engines with tonnes of torque - Get the pump and timing belts replaced asap and it should be a nice and reliable hack.

It's a superb engine, 197k is nothing to it if it's been maintained. With  a manual box you should get mid-40s day to day. It you should get a noticeable push when the turbo kicks in, if you don't it's not boosting.

 

Like any useful estate they can suffer a bit from being workhorses. The usual tell-tale signs apply- buggered brake discs, worn tyres of four different makes you haven't heard of, that sort of thing. Check the headlights, they have plastic reflectors and the silver falls off them. If the luggage blind is missing or broken it's about £50 for a replacement.

 

The Service light will probably be on, it comes on every 10k (and goes out 2 minutes after starting) and you need a diagnostic cable to reset it. LP or I can help you there at a cost of about £10.

 

They are definitely worth considering as long as the neglect hasn't gone too far.

 

 

LP does run his on veg. I understand they aren't the best on veg and he was considering getting rid of it because of this, but I think he's found ways to make it work.

Its the VW AEL unit in them, similar to the Audi 100 2.5. Good engines, plenty of grunt, plenty of 5 pot noise under load but silent cruisers.

 

My first Volvo was an R reg S70 TDI manual. Had it for 8 months and 20k miles, which in Northern Ireland means I was practically living in it. Never saw below 45mpg on the (accurate) computer, one time.when I brimmed it and tickled it the 50 miles home it showed 60mpg but that took some work! Could easily achieve 50 on a run though.

 

As said the headlights do fade but new Chinese replacements are available which my R reg V70R has fitted and they're alright! If you wanted to spend nearer £300 you can buy projector lights from similar sources but they look gash.

 

Most TDIs are smoky, people blame the pump timing but I think at this age especially its just a part of theircharacter. After a 50mph cruise up the Moira line on my commute every morning it would leave a proper cloud across Nutts Corner, I found it funny, others didn't. Mine also sounded (at idle) like it was about to die at any moment. They have a ticking noise at idle, pump the brake pedal and if it disappears its the plastic cam follower on the vacuum pump. Cheap parts but a big job to do so nobody ever bothers, never going to cause any big issues by being left to tick.

 

From.memory the tensioner or water pump has a habit of seizing on these if not changed with each belt. Happened my dads which he got new in 1999. This would have happened around 2006 and 180k, was still fixed but I think did bend a valve or two. Not sure if that's a common fault or not!

 

They used those engines right up to the early s80s and v70 ph2s, my ex had an early v70 ph2 and it was alright. But I don't think they have the same quality feel as the earlier cars, and it also didn't sound as good as mine for some reason.

 

That's all I can think of at this time.of the morning but happy to answer any questions if I can!

[warninglight]

Also RE veg, I did read up a bit on the subject at the time and due to it being direct injection the consensus seemed that it wasn't a veg friendly engine, where the 6 pot in the 740/940 is. Could be wrong about that but I didn't chance it! There might have been an article about it working with a twin tank setup to run veg once warm maybe?

 

RIP R130 DUS

I run my V70 on 90% waste veg and 10% petrol just now, as Richard hinted it's not the best engine for running on veg but it's not bad either.

It's a lot happier starting on veg than the old 6 pot D24 engine.

 

For some reason the Volvo applications with this engine are listed as "2 tank" and VW/Audi applications as "1 tank" conversions by Biomotors/Elsbett, I think it's an error, these are quite similar to the 4-pot TDi that is quite happy chugging away on veg oil, they have a dish in the piston that acts like a pre-combustion chamber in an IDI diesel, so engine oil contamination is minimised.

 

I've advanced the timing by 1.5 degrees, removed the thermostat for the fuel heater valve (so warm fuel returned from the IP is circulating in the fuel filter all the time), and I unplug the coolant temperature sensor on the cylinder head to trick the glow plugs into running for 30 seconds (I'd like a more elegant solution to this!).

 

It could do with a larger bore fuel pipe to the tank, new glow plugs, new injector nozzles... I'LL MAKE IT WORK!

 

Swap 4 XM?

[Lankytim]

Humm. Thinking about it I think I'm better off persevering with the XM as it loves veg, plus the V70 I was interested in is in Scotland, and that's miles away and scary.

That's the right choice I think, I'd love an XM 2.5 TD estate.

[320touring]

I could deliver the Vilvo if needed?

[Lankytim]

It's probably sold now anyway..

.... Although.. would it be possible for you to export it to England.. It's in Denny in Falkirk....

drop me a pm chap:)

They're superb on veg, but mine didn't appreciate starting at winter temperatures on the stuff, even with good plugs and long glows. Could have been the spray pattern (270k) or pump timing or lack of compression (not that I think there was) - but they're very intolerant of out timing which is a micron out.

 

So I added an engine preheater (240v) as well as the fuel preheater, then added an extra fuel supply line from the tank, and then it went like stink on 90% veg. I realised it supped the fuel very gently most of the time, but when you gave it the beenz, it drank like a fish, so one titchy 10mm supply line wasn't enuf.

 

Running high veg% on DI engines is ok provided they're asked to work hardish fairly often - that's the danger with 140hp and 200+lb.ft, they're barely trying on many of England's congested little roads.

 

Nothing better than doing 130mph plus on nearly free fuel!

[Mr_Bo11ox]

Id love to have this 5-cyl diesel engine in my 760, wonder how difficult that would be.

[warninglight]

I know when people fit T5 lumps to RWD Volvos they find a manual 960 to pillage the bell housing from, as it bolts up to the modular 5 pot. Not sure if the TDI uses the same pattern via an adaptor plate or anything. I'm sure it CAN be done...

 

I know of a guy who's fitted a D24 engine as used in the 760TDs etc. Into a late 960 estate...

[Richard]

It's a tight fit!

 

 

It looks as if everything you need to know is in that PB album. http://smg.photobucket.com/user/Kulmamies/library/940%20tdi?sort=2&page=1

Ooooh that looks intersting

An extra fuel supply line? That sounds interesting.  I need to sack off the very small bore and convoluted pipes in my Volvo V70 TDi.

[Lankytim]

Y0 SHITZ!

 

Will an 02 reg VULVA still eat veg? I've noticed that the later ones are nearly as inexpensive as the earlier ones. I have 1000lts of veg I need to burn through.

[NorthernMonkey]

Frayed knot.... '02 will be a D5 (common rail...silly high pressures involved along with extremely fine tolerances in the hp pump)

[Lacquer Peel]

2461cc TDI or 2400cc D5?

The last of the VAG engined ones are designated "2.5D" I think.

[forddeliveryboy]

Later ones are probably in the same price bracket as earlier ones because they're not so long-lived without splurging loadsamoney at them, from what I've read on here. It's certainly the case for C4 vs C5 Audis - a C4 quattro diesel will quickly find a home at a couple of grand, whereas there're loadsa C5 quattros offered for half that.

 

I think the 850/V70 shape looks better and better as the years pass. Might just consider one, if for no other reason than finding a decent A6 2.5TDi is getting bloody impossible. There was a faded red one on ebay a couple of weeks ago with interstellar miles but which looked unmolested, it didn't last long. Still plenty of V70 TDis around though.

 

I don't really like the idea of crosswise engines in anything much bigger than a 106 and heard engine mounts can be a pain and that '97 on breathers are a tad pricey. Any other built-in nasties to look for?

[Lankytim]

Ah, this one is indeed a D5....
