I have a 2005 astra 1.7 CD 100 pi, Club. The turbo is whistling now its got 70k on the clock. I think it is a Isuzu engine.

The turbo specialist recommends a refurb, To save money I am looking at taking off myself.

Could anyone please give me any tips or advise on how to remove it and re-install it after the refurb.

Also, it there a owners manual available for this model?

Many Thanks
