Laguna 2 DCI. BLOWN TURBO

[Lankytim]

Some of you here may remember a topic a few years ago where I mentioned my mate had bought a 53 reg Laguna diesel estate for £3500, which is apparently 3 times what it was worth at the time.

 

Anyway, it's done the obvious thing and shat it's turbo. No runaway engine, no other engine damage, just a smoky oily turbo.

 

The big question.... how difficult is it to just wang a good used turbo on and drive away happily into the sunset?

 

All suggestions to just crush it will be taken on board as a last resort.

[overrun]

I can't see it being too difficult, if you/he know which end of the spanner to use.

 

Cost is the main factor here.

[cort16]

Why do these shit themselves so much as, as far as I know they use off the shelf garrett turbos don't they? Is it an oil feed problem?.

[Pillock]

Because it was touched by a Frenchman.

 

Turbochargers are pretty simple bits of kit, nice chunky bolts and an oil feed. Shouldn't be too hard but I'd question the "happily" bit, if I were your mate I'd be getting it fixed and moved on before whatever caused the turbo death strikes again.

I'm not sure of anything causes turbo failure on these things as such, they just go from time to time. He want's to know if I want it..... Hummm.. how cheap is cheap enough?

[The Reverend Bluejeans]

They're no worse than anything else, and it's down to how it 's driven and serviced. Turbo Technics sell more 320d and VAG turbos than DCi Renaults. They are pretty simple to replace ad there is plenty of room to get to it. I'd go fot a TT recon at around £400. Used turbos are a bad idea.

53-plate Lag with a toasted blower? Bridge money.

[Jikovron]

From the odd time ive swapped a turbo even for ones that arent for the car etc its not a difficult task nor that expensive especially with diesel turbos being no use to whip onto the nearest pinto etc  , only trouble ive had is threads coming out with the locked together nut/stud and aged return hoses being brittle as heck but as everyone knows its space to play with that makes or breaks a fairly easy task

[Lankytim]

Well he's been quoted £1200 to do the repair which I thought was pretty excessive!

[The Reverend Bluejeans]

Fuck that, bring it to me. £400 turbo and 4 hours labour does not equal £1200.

[The Reverend Bluejeans]

Must add: I ran an 04 Slaguna DCi and ended up really respecting it. They are a lot better than some of the overrated shit out there.

[Lankytim]

I went in it and didn't like it, just couldn't put my finger on it. Still one of the best looking motors on the road though.

Git high chairs iirc

Finding a good secondhand turbo isn't easy and will set you you back over £100. If you fit a new one they won't give a warrenty unless you fit lots of extra bits which push the price right up. As has been suggested it is scrap money. If you do repair it expect to get around £700 for it on a good day assuming it is a tidy well looked after car

[Albert Ross]

Best of luck finding a good used turbo. Also, cure what caused the failure at the same time.

[Vince70]

Well don't replace it with a 2 litre IDE engine as that's even worse than the diesel the Laguna 2 is a terrible car I had one from 3 1/2 years old and in the year I owned the thing I didn't know so many parts could fail on a car.

 

It spent more time in the garage than on the road and when it did drive it wouldn't go over 30 as it seemed to be constantly stuck in safe mode.

 

I ended up swapping it for a rusty mk4 fiesta just to get rid of it as it was only worth scrap as I couldn't of sold it to someone.

 

If I was your friend I wouldn't spend anything on it and spend the £1200 on something else.

[The Reverend Bluejeans]

The IDE is indeed a shocking turd.

To answer the question of how difficult it is - its not. It's a really easy job, I done one about 3 weeks ago. It's a bit fiddly but take your time and its two evenings work.

 

However to prevent catastrophic failure of your new turbo you will need to change the intercooler, intercooler pipes, oil feed pipe and obviously give the engine a very thorough service.

 

My advice would be to not change the turbo as anything other than a brand new one is a waste of time. I would say your best bet is to try and make some of your money back breaking the car for parts. Decent leather interior, tidy wheels, fuel pumps and xenon headlights will be where you make tidy money and any other bits will make up the extra. The shell and engine (presuming you can't be bothered to separate) will then go over the bridge for £120ish a ton.

 

Good luck

I'm sure I saw recon ones on ebay for a couple of hundred quid but they're probably made from melted down matchbox cars and lollypop sticks,

[Partridge]

Is the turbo completely fecked, or just gummed up and flooded with oil? It’s possible to rip them apart, clean out all the shit and rebuild them-I did it on a Merc Turbodiesel a few years back.

If it’s flooded, the bearing and sills might be at fault.

[Lankytim]

I dunno exactly what's up with it TBH, just that it's munched it's turbo but the engine hasn't been damaged. In my minda new turbo, oil feed pipe/return and draining of all the intercooler pipes of stray oil would see it back on the road. Given the cars horrific reputation as bridge fodder after similar failures I can't help but think I'm missing something.

 

I don't think my mate CBA with breaking it himself. I've given him the lowdown on what I think and he's going to have a think about what to do next. I've said that if he wants to ditch it I could be interested, OBV for bridge money.

[cort16]

He's not been on for a bit by R9UKE knows all the right places for bits for these and all the potential pit falls.. It's maybe worth sending him a pm to see what he has to say.

[Sean]

What you say will see it back on the road but not for long. Stray fragments of metal will be in the intercooler and pipes. Many sites and stuff will say just draining the oil out is fine, but there WILL be metal in the system that WILL become dislodged and destroy the new turbo.

 

If a job is worth doing its worth doing well.

[Lankytim]

So, does it need a new intercooler and pipes or will a good soapy jetwash do the trick?

[Partridge]

You say it's munched the turbo?-I take it the scroll itself has had it then?

Deffo a repair by replacement job it that is the case.

[Lankytim]

Yeah the turbo is smoky, so possibly just the seals but then it could have lost some turbine blades, I'll have to speak to my mate properly about it rather than just by txt msg. 

 

What's a scroll then?

[chaseracer]

The twirly bit inside the turbo housing that compresses the air.

[Lankytim]

I thought that was the compressor section, and the exhaust bit was the turbine?

[Sean]

As a rule of thumb with these turbos (GT1749V) if one section has gone just get a new unit.

 

You'll never clean out the intercooler and pipes effectively enough to guarantee no fragments remain so a new intercooler and pipes is required.

 

But you need to weigh up cost vs risk vs final worth and these cars are worth next to nothing. Please don't buy a cheap eBay reconditioned unit, buy a new one if you do go ahead with it. Experience tells me that recon or cheap China made parts are really shoddy

[Partridge]

If the scroll/swirly bit has had it, I’d make sure I didn’t run the car unless I absolutely needed to. You don’t want a piece of turbo going where it shouldn’t do, or the poor thing will be clusterf**ked.

If it’s the seals though I’d say strip it down, clean it and bung a fresh one on. But be careful if you do, the swirly bits aren’t as tough as people often think, and also be prepared for oil to go EVERYWHERE so open it up in a washing up bowl or something if you can.

Make sure that the seal is the exact part for yours, same year, everything. Manufactures tweak these things, and if you get a part that’s a year out for your model you could be stuffed...I speak from experience 

 

Without actually seeing it or being there, that’s all the help I can offer for the time being, but I hope I have helped
