Pull the turbo to intercooler pipe off and i'll bet its full of oil.
My old Cav turbo was the same.No smoke while driving,still boosted fine.Stop at traffic lights/junctions etc and it would belt out.Was fine on cold start up but once the oil was up to temp and a bit thinner thats when it would smoke.

just finished rebuilding a C20let and Z20let and sounds to me like you could have a nice little combo going on. If its anything like the engines i've helped on then you might find that your turbo is fucked the pistons are gone and the oil stem sills too. only way to check is to take it apart but once you've done that it means rebuild and wedge. with teh turbo take it off. takes about 15min if that and you'll know straight away if its fucked as oil will be all inside it.

You can't just take one of the boost pipes off and check for oil. Sometimes they can leak oil and go sraight into the exhast through the exhast side of the turbo. Needs to go to somone who knows what they are doing. Also these 1 month warrantys are never any good especially without any documentation for what you are covered for.

This is why you don't buy cars off ebay without even looking at them unless you know what you're doing.

100% Turbo failure! like everyone tried to tell you in your previous thread!
It wont be rings or stem seals on a ZLET with under 100K
ALso when you get the Turbo fixed expect some smoke as the intercooler and pipework will be full of oil. it will eventually clear out but try to get the worst of it cleared out.
If the problem isnt Turbo related i will chew off my right arm!

I agree it sounds like the tubby. what were the Vaux approved garaged thinking when they said the smoke is from overfueling?? Most noobs know blue = oil etc

took the pipe off the turbo, almost no oil at all, the engine is "breathing" alot when we took the oil filler cap off, my mechanic is saying it is defo piston rings and to get onto trading standards to let them sort it

have you unbolted the turbo its self? When resent repairing an engine we did everything but the turbo as we couldnt find any oil but when everything was new and still smoking we had another look by taking the turbo off and there was oil all inside it

the valve stem seals went on my sri turbo T 80k mate so it could be that,
the way its been described is exactly the same as my one went on idle it would puff out plumes of smoke
