cannot view the video
your turbo could be a vnt one and they dont have wastegates/dump valves......what year is it?

if you have the noise i think you have its the compressor wheel on the compressor housing

 

[Guest]

Ah right, I think it is a VNT, my car is a 16v1.9 140bhp. Year is 2005.

I found a different link, Zafira vxr turkey noise turbo catter - YouTube that's kind of it. The compressor wheel on the compressor housing? That sounds expensive

Jim 33, the 156 diesels don't have dump valves, they use VNT turbo's. Try googling Zafira vxr turkey noise turbo clatter and you may find the answer. It seems to be vacuum related.

Right, or could it be the turbo vanes sticking? And could this turbo chatter be causing my overboost error?

I will be blanking the EGR and getting some of that innotec turbo cleaner to see if that helps. Am I wasting my time and money doing this?

 

[hdseven]

the link still goes to the same page and wont run for me
vanes sticking is unlikley to make the noise but will cause boost problems
worn journal bearing letting comp wheel spin against the comp cover will make a noise, so will worn thrust bearing, you need to take the piper of the compressor housing and have a feel at the movement side to side and back and forth
your are wasting your money on a cleaner if thats your problem

ok that worked heard it.......
get that pipe off the comp housing and feel for play

 

[hdseven]

fordy86 as been having probs with his turbo and this is a shot of his.........see how the impellor is rubbing on the comp cover, this will jam and snap eventually, if this is your problem you need to find out asap and factor for a recon or used turbo

Thanks for the reply hdseven, I'll get to that through the week.

Damn you also for giving me bad news:lol:

I just bought this car and already had to replace the inner cv joints, replace all four tyres, needs a new front wheel bearing, and failed its test on the rear bushings. To say I'm a little vexed is an understatement...

What sort of money am I looking at for a recon turbo in the UK? I sourced one here for a French car a while back for about €350.

Hi Mate,

Did you get this resolved in the end, my GT 1.9JTD is making this noise now...

You might have split VNT hoses. £5 fix on ebay. Search the forum for the measurements and more info.
