What do you know about vectra cdti V6's?

[Bren]

What are they like on fuel? Road tax? Parts prices? I know they can get expensive when they shit themselves.

[Kiltox]

Rare. Almost autoshite material (in the stupid engine choice nobody wanted sort of way) Sort of want.

[LessThanEqual]

There's one that lives near me which is used as a taxi. Can't be that bad.

[Cavcraft]

My mate with a VX/R Vectra says the 3.0 diesels are on par with a 2.8GSi petrol.

[twosmoke300]

In power or massive shit itself potential?

[Cavcraft]

POWAH

[Ghosty]

Is it too soon to say 'don't fit Nexens'?

[JohnK]

They have good crash protection.

[NorfolkNWeigh]

Don't the cylinder liners fall out or summat? I seem to remember getting the horn for a 3.0V6 diesel Saab 9 to 5 a few years ago and there were a lot of Internet horror stories.

If they're anything like Merc and BMW 3.0 Dizzlers I've had they won't be great on fuel round town , only come into their own on motorways, but then the mid range grunt combined with 40 odd mpg becomes addictive.

[SiC]

They're awful. Really awful. Same engine as in the Saab 9-5 and Renault Espace and Vel Satis.

 

I can't begin to list the faults they suffered.

 

The only way I'd entertain one if it was really cheap and prepared to throw it away at any point.

[twosmoke300]

Aren't they the ones where a rattly dmf kills the crank shells in pretty short order ? On top of the liner drop issues and wrong length dipstick !

[SiC]

Did Vauxhall do the twin turbo 1.9 diesel in the Vectra? Saab did it in the 9-3. Not that strong (habit of sucking in swirl flaps) but far, far better than the v6 and similar/more bhp and better economy.

[stripped fred]

I think it all depends on how cheap it is. There's a certain satisfaction in driving something everyone else tells you not to if you've bought it cheaply enough to throw away when the first big bill comes along.

That and tensioners don't last long (usually take things out in a big way when they fail), constant water leaks, overheating, injectors failing and then all the usual diesel emission crap too.

 

I'd say go for it, proper AutoShite car

 

Just don't come crying when it dies.

[dome]

I remember getting some bits off a boy breaking his 9-5 V6 diesel after the engine shat itself. He'd bought another one and wasn't happy when I told him what mpg my Aero was getting which was barely any worse than he was getting. I'd avoid.

[Rusty_Rocket]

It's an Isuzu engine isn't it?

 

I've zero experience of them, apart from a ride in a Signum (I think) with this engine.  It had a serious amount of 'go'.  Not surprised the DMF doesn't last very long!

[Cavcraft]

The fun Bren would buy one.

[sierraman]

One for sale on Autotrader at minute, auto though so no DMF problems. I think the Police used them a lot. I bet the torque was monumental on them, make a good tow car.

[rantingYoof]

SnrYoof has a 3.0CDTi slushbox in a Signum rather than a Vectra.

 

Insane torque. Just, stupid. 170hp or so, but the torque makes it feel double that.

 

It's been completely faultless over around 60k and seven or so years. It now does incredibly short journeys and is abused as a tip-run vehicle and it still refuses to die. The EML light apparently means nothing. It's due a cambelt too.

 

But highly recommended just for the torque-lawls.

[406V6]

3 litre V6s are for WINNAHS  (even though the one in this thread is diesel)

[rantingYoof]

To answer the pressing* query about fuel economy, the 3.0CDTi Signum with a five speed slushbox will get 42mpg on a saintly run and 30mpg on average over a tank.

 

I imagine with a six speed manual and more control over the turbo and fuel use it could be improved a little bit. The torque is addictive though.

 

It's a brutishly heavy engine and not particularly modern. I think it was 'worse' when used in the Saab 9-5 - tended to kettle itself a lot.

In the same vein as the suggestion of the TTID 1.9 earlier (which is 180bhp IIRC), ten years ago I test drove a 9-3 with a Hirsch tuned version of the 150bhp 1.9 which had a similar BHP level and it was a bloody riot. The midrange was unbelievable. In the end I bottled out and took a 120bhp version instead (company car)

[SiC]

There was a ~07 Saab 9-3 TTiD auto with 180k on the clock that went at Cannock when I last went for £1800. Luckily I didn't have the £100 deposit monies on hammer down. Even sent the wife to get cash out at the local pez station - their cash machine was broken.

 

Probably would have blown itself up, but I was exceptionally tempted.
