Very Big Problems
I have rebuilt the engine on my saph cossie, 3 times, and every time it after it smokes on over run, change block, pistons and the lot, but every time its smoking, its got big breather kit on it, I no its not that, only when it on over run at about 4000 rpm, then press the pedal and a puff of smoke. I am completely lost with, any help well appreciated.

Could be the grade of oil you are using ,had this problem when i first bought my 3dr.pulled off head and did guides etc,even though they didnt need it,put head back on still smoked on the over run,so fitted new turbo,still smoked,changed to 10/60 oil problem solved

Is the puff black or blue?
if black its overfuelling if blue oil
Check turbo outlet to cooler is there oil if so turbo seals have gone. if you have replaced turbo have you cleaned out intercooler? oil residue in cooler when hot goes into intake and burns
Also breather block under intake is that clean? excess pressure will cause piston blow by..
What chip and injectors are you using? ab chips overfuel a lot
Hope you get it sorted m8

drop the oil, use 10 50 or 10 60 run it a bit to clear all pipes and exhaust
as in run it like fook or swap exhaust for clean one ,takes fooking ages to clear oil in exhaust!!!!
new clean exhaust still smokes on overun probably stem seals
happening to me at pesent

this sounds exactly the same as my car.only on over run and then slightly touching the throttle will give a puff of smoke. smokes a little on acceleration too. the head has just been refurbed and its a 10k mile rebuilt block so guessing its neither of those things. could it be the turbo then??

I guy called roger carty has had the car, and we have put a new turbo on, one that we no doesent smoke and still does it. checked all compressions, leakeage test, all ok, the car is running greens, but its still in running in stage.
Car is on just mineral 10-40. to run in. do u really think it could be the grade of oil??
anyway had 18 months now done 1000 miles, sickener.
oh and stem seals were done as were guides. had new rings etc.
going to get fuelling checked, think it could be bore wash, not so shore though.
and its definatly a light blueish.

got the same problem with mine. engine was only built last year. there is play in the shaft on the turbo though, so it was posted off today to turbo technics. fingers crossed 
At a wild guess i would say either your turbo or valve stem oil seals... But as i've changed both then i dunno...
When my turbo failed there was oil all in the exhaust for months after i replaced it...Takes so long to burn off!

i have a similar problem,smokes on over run and quite badly also
the engine i have rebuild using new seals and valve guides and new rings etc
also running a tidy breather system and no kidney box and no breather return to air box either
so im guess mine will be turbo seals , im booked in a interpro for a tune/check up soon so ill know more then
im running t34/rs500 intercooler,plenum spacer ,greys,3bar, and is running rich so that wont help either
ill reply after my tune up with an answer
