When the turbo kicks in I get a puff of smoke out of the exhaust, I have just changed the turbo as I thought this was the problem but it's still smoking and advice would be great and try not to make it too painful guys....,,

 

what colour is the smoke?

 

Not sure will go out later for a spin, can you give me examples of all colours mate

 

Black
Blue
Grey
White

All indicate different 'issues'

 

bluish/white

 

White is water normally, blue is oil.
Was the turbo you bought new or used?
Have you checked all the pipework?
If in doubt, seek professional help (dealer/speciallist).

turbo was used but seemed in good nick, no play etc, all pipework seems fine.

 

have you checked for any hg issues? could be lots of things now, take my last bit of advice and go to a professional to get her diagnosed, would have probably been cheaper in the first place than replacing the turbo

ok cheers mate

 

Depends alot on the type of smoke and how its been mapped> mines pretty rich as full boost is reached and i get some black smoke from it when driving hard from low down revs< It is purley coz its rich. so have it checked, But not all smoke is a bad thing

 

yep most likely can be turbo as my seals went aswell but could not tell as it was the inner seals on the turbo

 

Ive always got a puff of black smoke on boost in all my impreza's. Never worried me.
