Anyone want to hazard a guess as to whats happened here?

Looks like the bearings or shaft have failed making the blades come into contact with the housing?....

Next guess! (you may be right)

looks like something made its way down the inlet to meet the compressor, it does also look like the comp wheel is off centre like the shaft is bent or its got a very very shot bearing.

May look off centre due to the angle of the picture. Its still on the van.... yes its my Transit, whose turbo decided to fail yesterday by making a police siren noise. Nothing else, no oil burning or power loss although this may have a been gradual.

£400 quid later i now have a turbo that looks like this -

(thumbnail!)

Its a brand new Garrett GT20, from Ford it would be nearly 800 squids...

What tranny do you have? ive just done the turbo on my old 2.5 a unit from ford was as you say £800 i got a generic un named one brand new for £280 and im getting much better mpg and power than at any time in the 6 years ive had it and it has a turbo whistle quite loud as it comes on boost which it never had in the time i had it. mine siezed up anyway which made (and this is no exageration) it smoke black with the volume of smoke you would get from burning old tyres, and such little power i could not get out of 1st or over 2k rpm. made it kind of tricks to limp it to work in rush hour

Its in my sig.... but its a Mk6 Transit 2 litre tddi.

Fuel economy has dropped a little i must say, once this new one is fitted (and the cat innards removed

) i should get it back, and more performance...

Where did you get the turbo from Gareth as im just wondering if mine is due before the year is out as its a right whistler

Maybe go for a hybrid if its not much more money

Something definately got into your turbo though as i cant see a turbo just failing like that on its own

I got it from ebay, from a guy that bought a job lot of stuff turbos included he had 2 left... A recon will be as good and this could be done for about 250-300. If my Activa ever needs doing i'm having a bigger wheel put in.

The van is all sorted now, and its more responsive and torquey, and quieter!

Looks like its sucked something in

Was there any play in the shaft...

None at all! Just the compressor wheel is fubar.

Hi all

If your turbo is getting a bit noisy you can just buy a re-furb kit for it, they are about £45 , im going to be getting one shortly for the TCT, you get new bearings, seals, nuts and bolts you can also buy the turbine and shaft but they dont come with the kit.
The turbo itself is a doddle to do as well so there is potential to save quite a bit of money for very little head scratching, which is always nice

That'll make for a good, interesting "how to" post Dean

I've never been inside a turbo and frankly, the prospect of doing one scares me more than rebuilding a 4HP20

Gareth, I was worried at first that the turbo was off your Activa

To be honest i thought that a turbine would have to be balanced by a pro unit due to the speeds involved it would need to be checked, specially if you seperate the turbines from the spindle??

I did wonder how i was going to ballance the core when i took it apart the first time for a lookie see, what im planning on doing is using my magnetic model prop ballancer, it seems to work a treat, but of course i shall let you all know when i eventually get it done and it throws itself apart, then you can all point and laugh

Jim it was STEELCITYUK who inspired me when he rebuilt his 2.5 TD XM engine, he did a good write up on it and the turbo rebuild with pics and pointed me in the direction of the guy on ebay who can supply the rebuild kits for Garrett and KKK.
