Right, after all the garage shinanigans I have another mild problem.

When I back off the throttle and change down a gear to slow down, blip it, a puff of smoke comes out. It has never done it before and only does it when you have come off of boost.

Any ideas what it might be?

 

unburnt fuel on the overrun

 

Doesn't smell like fuel.

 

is this on a turbo car? Has it been setup recently?

 

Yeah Fiesta turbo.

No it hasn't been set up.

Although it has had minor ancillery work inc: new alternator, new sparks and leads, new cambelt, new aux pulley and belt, oil change and filter.

Worrying

 

What colour smoke are we seeing?

 

its not a major puff, almost like someone breathing out their fag smoke. Its white to blue colour.

 

BTTT

 

sounds like turbo so far.

 

imo turbo seals

 

shizer.

Thought as much.

Will get a new turbo
