Ok,
Ive checked all the breathers, All clear

I checked for play in the turbo, There is a tiny bit but no more than when I fitted it

I turned the mixture down as far as it would go, The idle has become very lumpy

Still smells a bit rich

Held the revs at 1500rpm, Still smokes but very little

Drove down the road and came to a junction, Slowed down and there was quite a bit of smoke.

Went for a good thrash for 10 mins then pulled up at a petrol station and left it to idle whilst I checked my tyre pressures, No smoke

Drove back home, Stoppped at a junction to turn right, When I set off there was a puff of smoke, Pulled down the drive and left it to idle for a min or so, No smoke

So is it down to bore wash, Duff turbo or summat else
