Changed uppipes,bluish-grey smoke behind turbo

Hi eeryone,got f super duty 97,had to cut floor to reach passenger uppipe bolts. and driver side wall got bent with air chisel,its so tight out there,spent about 40 hours
changed turbo o rings,bolted everything back,now so far ive circled around the block topped 40mph and about 15-20 lb of boost.truck has crane and dump bed -weights about 14000 pounds.
right after first 500 feets its started to smoke some bluish-grey smoke off turbo-upipesarea.doesnt leak anything.since i have hole in cab its all goes inside . what it could be? up pipes are dorman with y collector.
it started to leak oil when i changed glow plug in the back passenger outside corner(i think because i couldnt bolt back 1 stud right next to firewall)but i got flex socket and did it today so it seems doesnt leak anything.
Smoke much more if i press throttle.doesnt smoke at all at idling.
Googled for an hour.didnt find similar quizz. thanks

If itís smoking the doughnut area is probably leaking is my guess. Dorman historically have not been the best quality of parts and this might be the problem. Leaking VC gasket on the back bolt if not tightened will drip oil...

Anti seize compound will smoke for a while after you put everything back together. You did use anti seize on it, didn't you?

sorry for late respond,didnt get respond and forgot about this thread.
I just took apart turbo again and rebuilt with 360 kit of ebay.also seems like i have had shaft play and did mistake when put back turbo cartridge i didnt pressed seal in it but put together on bearing housing side.so i assume that seal gave some play i felt when i installed it and that *wrong noises* during test drive.
started it for couple mins.sounds quieter than it used to be also under throttle turbo sounds like it should be(based on youtube videos)
yes i used antiseize on uppipe,collector bolts. I believe i tigthened uppies good.
What would be options if current turbo blow apart somehow. i didnt dig too much. just buy knockoff replacement for $350 of ebay or some other options? i dont need this truck to drag race.just bare minimum to match accelerating other cars in traffic.
it has 6 pos TS chip, no muffler or cat . 6637 air intake.
Sorry for long texts.i do read alot before i write but always nice to hear 2nd opinion when you are not that familiar yet.

I personally like doing business with Dave at XSBoost turbochargers, he really knows turbos, is willing to talk to people if he's available, and has some of the best prices I've seen.... My name's Dave, his name's Dave, no relation.......
