Turbo help

[gus-lopez]

I have pm,d you my number

 

[Littlewheels]

Heres some piccys to help what you’re looking for. Make sure it’s cold, so you don’t burn yourself.

On the A7 Autovia del Mediteraneo going towards Andalucia if you exit signposted "SaprelorcaPoligono

Two brilliant Funsters here going the extra leg to assist, well done fellas.

 

[Baggydave]

Yes indeed brilliant help & all so willing to go the extra mile for us. Thank you all so much.
I will continue to add details of how we get on with the journey home.
I’m amazed that we could not find a garage willing & able to even look at the problem. We even tried truck places. Perhaps by the time we get home our confidence in the van will be restored. I do hope so.
Thanks once again.

Try checking the throttle connection (a) the connection on the pedal (b) the connection to the ecu n/s under the glove box that was my problem previously.

The turbo in question is on an engine without ecu, all mechanical.

 

[Flairy]

I spent along time convinced the lack of power on hills was caused by the turbo made sure wastegate was free,then replaced with new turbo no difference ,then found that the throttle wire up to the ecu was not sending the signal for more power ,after soldering the connections to the throttle assy still not right ,following the wiring under the dash found a white block connecter took the wires out cleaned them runs like a train now problem solved ,mine is the same build time as baggydave

I have changed a turbo on one of those vans awkward bugger grab a cheap pressure gauge and a bit of tube to tee into they only run at about 12 psi

 

[Baggydave]

Morning all. We are now 80ml from ferry port on Spanish coast having got booking for this evenings boat.
We live about an hour from U.K. port.
Lots to think about when we get home but I’m leaning towards a complete engine overhaul/ exchange/rebuild. We hate driving something that’s not right. It puts a complete damper on trips.
Hopefully I’ll find an old school mechanic who will take on the job as we really love the van & I think it’s worth it.
I’ll keep this thread going to the end solution as I don’t like leaving things hanging.

Thanks once again you have all been fantastic with advice & moral support.

My son had turbo problems in his Car cost him £ 800 to have the turbo out and reconditioned and back in . Mainly labour costs.That was an old school mechanic with a back street garage. No fancy facilities.

Hi
We are in Spain , Mercia in a town called Lorca heading for the coast. Our van is a fiat 2002 2.8itd Eura mobile. It’s got a dodgy turbo & is making driving very stressful!
Very poor hill climbing & will only rev to about 2500rpm before it feels like it’s stuttering like it’s running out of fuel.
We had one period when full power resumed & driving was great, but 30mins later back to old ways.
We have tried garages along the way but they either aren’t interested or busy.
Can anybody suggest a garage or what might be the problem?
Thanks in anticipation & any suggestions will be greatly appreciated.

Have you checked height of carpet under accelerator pedal? Happened to us once after purchasing a second hand van. The new carpet was too thick under the accelerator pedal thus was preventing the turbo from kicking-in!

Hi
thanks to all those who helped support us on this trip. We are now home & van is on the drive. Now to get it sorted. I think compression test & turbo check will be the first two steps.

Have you had any luck sorting your lack of power issue yet.

 

[Baggydave]

Have you had any luck sorting your lack of power issue yet.

So far no. But it goes into local (Hailsham) diesel specialist On 27th for turbo, compression & injector test. I will keep the post posted.earliest I could get it there.

I have also got a price for rebuilding engine £6500 inc removal & fitting. Did not include new injectors or turbo.

 

[Baggydave]

Just to keep this updated & so those interested get to know the result.
the diesel specialist contacted me yesterday to say he will not/cannot do a compression test because he fears the injectors will break when he tries to extract.
i Chose a specialist thinking he would take that into account when accepting the job. Apparently not! I have cancelled the visit.
I’ve now arranged for my usual garage to sort the turbo. It’s only nuts & bolts after all.
it’s become apparent while looking for repairers that most don’t seem to want the work if they cant plug a computer in to see what’s wrong. hopefully this will sort the problem.

 

[Manic]

Earlier in this post I said I had similar symptoms , we’ve just returned from a winter stay in Suffolk and whilst there I fitted a new fuel filter( it was due anyway) but we had also refitted the original Hymer carpets for the winter and on moving off pitch I noticed the throttle pedal didn’t move as much as it should, so removed carpet and mine now pulling as it should.
No help to you

 

[Bessy765]

No one has mentioned the exhaust, if it has become partly blocked it will give similar problems. Might pay to take the silencer off give it a few gentle taps and see what falls out. Over the years I have found this to have happened on a couple of vans. It costs nothing but time to check!

[Figaro]

Bessy765 What does it block up with ?

 

[Bessy765]

Soot particles, parts of the inner silencer caused by corrosion, unburnt fuel, look how much water comes out when starting from cold, short runs etc. not common but possible and a bit irritating if having spend time and money when a simple half hour check will see

 

[GeoffnDee]

The filter , that I expect you will have , on the fuel pick up pipe in the fuel tank could be worth checking in case it is partly blocked or the pipe is faulty.

There are a couple of videos on Youtube which show a pneumatic kit which is designed to remove stubborn injectors, ask if your garage, if they want to remove injectors but are scared of them breaking, could get hold of such a kit.

As for the partially blocked filter idea you could also watch Youtube videos about blocked dpf (not the same obviously but I think would cause the same effect and dpf do tend to block now and then).

I’ll give it a go when the b****y rain stops. Worth a look. Thanks I never thought of that. Although I think in my case it’s unlikely.

No def on my van like me it’s too old.

Yes I’ve seen them. If turbos not the prob I’ll buy one & have a go myself. What can go wrong

Yes I knew that, but what I was saying was that a result of a partially blocked exhaust could manifest itself the same as a partially blocked dpf.

Just seen this thread. I have the same engine. Apologies if I’ve missed something in the thread. My original thought, as others, was a sticking open or defective wastegate actuator system, could be broken spring, perforated diaphragm, leaking or broken pressure pipe etc. Have you been able to confirm you have boost? This for me would be step 1, assuming the basics like fuel and air filter are OK, do you know when they were last replaced?

Then check the turbo itself, take the discharge port off, does the impeller spin freely? Is it picking up anywhere (bearings) Any smoke ? Check the inlet pressure pipe to the intercooler and back to the manifold for splits and leaks, and pressure check the intercooler.

Hi all a final update I hope.
This last week I have been cleaning/polishing the outside of the van which meant I had to move the van around the drive. On Tuesday on starting it emitted a tremendous cloud of black smoke. Never seen anything like it! BUT the engine sounded different.
So I took it up the steepest hills I could find locally. To Eastbourne then on to seafood via Severn sisters.
Powered up the hills, still with a little smoke but in 3rd gear.
Feeling good at this point so when I got back I thought I’d change the fuel filter, it’s the only one I haven’t done since returning. Which is what the mobile mechanic was going to do this week.

On removing the filter I emptied the very black contents of said filter into a plastic tub, see pic. It doesn’t even look like diesel to me. Very thin.
I refitted new fuel filter after filling with clean diesel.
Took it over same hills today. No smoke at all & even easier than before.

Only other thing I can add is that I put injector cleaner into full tank of uk fuel a few weeks ago.

Could I have got some bad fuel somewhere which sooted up the turbo/exhaust?
I’m baffled but elated.

Ever so pleased

Hi.
As a final update to this thread & for future readers. We have just completed a 3k trip to Portugal. Van is going well & still no smoke & passed mot no problems. It’s a keeper for us.
Really pleased on how it performs on hills & motorways now. As long as I keep revs above 2k it’s fine.
Averaging about 25mpg so not too bad & everything still works!
Will give it a service soon & change all the filters inc fuel. Lesson learned.

 

[Landy Andy]

Good result. I’d change the fuel filter again now you have had some mileage and see what the contents look like. Will indicate if all good, or if you have a contaminated tank.

 

[ChrisL]

I'm not familiar with these engines so you may need to research this further but the diesel you recovered from the fuel filter appears to be contaminated with engine oil, on my old Mitsubishi 4M40 engine this indicated that the fuel pump oil seal was failing and sucking engine oil back into the pump when the engine was turned off, as I said i'm not familiar with your engine so can't say if it's likely or even possible but maybe worth investigating. Also regarding injectors there are companies around who have the tools and the knowledge to remove seized injectors, you just need to find one close to you. The following video shows how they remove the injectors on a Renault Traffic and how they deal with the last injector which breaks, if you just want to see the injector removal watch from about 6:12.

Prior to our long trip we did a fair few miles in the uk & Brittany. I changed the fuel filter after those & it was pure diesel & clean as a whistle. Van does not use any oil between services either. I do change oil/filter at around 5k as I want to preserve engine as much as I can. I change fuel filter once a year before mot as normal.
It starts on the button even in the cold & frosty mornings. Mileage is around 100k miles.
