Also any useful tips for replacing it? I've no experience of these motors

Thank you

Yes - the wastegate can stick if it's not lubricated very regularly - this will put a hole in a piston and wreck the turbo as well!

Isn't it the 1.7L Isuzu which you can find in the Astra diesel from @ 2003

It is but I'm not sure which parts are the same - the wastegate doesn't stick when they aren't used in a boat either!

As far as i believe it is Vauxhall's own engine and not the Isuzu lump, as for turbo repairs try Turbo Active, have used them before and they offer a great service.
Turbo Active

We had one and did the research - Vauxhall use the Isuzu engine as well - Cummins regret using it bigtime and caused them a lot of grief - the 2 litre replacement is fantastic in comparison.

Hi Martini

I've just finished fitting a new turbo to my parker 6.3 today. The wastegate had indeed seized and the whole unit was very corroded and therefore could not be reconditioned. I purchased a new turbo via universal turbo's in Sandleheath who were really helpful and knew their stuff. They soaked the old unit in an oil bath and managed to remove the manifold so that saved a few pennies. The new turbo was 795+Vat. When i originally stripped the turbo i had to rip the turbo blanket which had welded itself to the Turbo. I would have probably tried to salvage the old turbo blanket if i had known how expensive a new one was. 300 inc for the turbo blanket.
I found it a very fiddly job, the only advice i could offer would be to go careful when tightening up the bolts on the new unit as they are only threaded into an aluminium block and if i did the same job again Id invest in a flexible extension to get to the awkward jubilee clips. Hope this helps.
