The smoke situation, I've had similar over the years ALWAYS after engine rebuilds. The running in process is not good for turbos. Any fallout ends up in the cartridge and just wears the seals. I learnt my lesson and fitted a pre-filter (inline) but that isn't always fool proof and just another thing to leak or go wrong (+if it blocks...). However, I remove them after running in. Even your builder may not have been 100% clinical or the machine shop. It happens. I'm not sure what a bore inspection would do, but compression testing is easy and cheap. Would be surprised if it was anything other than the turbo. Be worth whipping off and dropping at a local place for inspection. Or you're replacing it no? So wouldn't worry too much if, the latter. See if it gets worse. Check the cold side and see if it's passing oil there too, make sure your return is not kinked etc. I wouldn't be too down heartened. Great content by the way - I'm local in Doncaster, if you want an opinion or a brew 😊
It's in at Giz now, turbo is healthy but oil pooling around the top of cylinder 4 on the intake side. So looks like an incorrectly installed or damaged stem seal on the intake valve. I did suspect the turbo since like you say, the running in oil isn't great for bearings, debris collects in the cartridge, and it was run with no oil pressure before the rebuild. But no shaft play and the boost pipes and downpipe were bone dry upon inspection this week. Will do a video update when I get it back, thanks for your comment!
It's great, I'd still recommend it. I guess it depends on your budget though, since you can get 90% of the features for probably £100 less with the cheaper eBay/AliExpress Android head units.
who's is that blue astra it looks proper slow

Was that last car at the end of this video an actual Chevetterolet?
how is your teyes head unit doing? is it any good and is it worth me buying one? Cheers
