1G 1991 TSi Smoke coming from top of turbo mounting bolts on exhaust manifold

So after getting my car back from transmission work, after driving it the next couple days, there was and issue of it overboosting at like 20lbs when it's supposed to run 15ish. Later the next day then the dip stick popped out while driving but nothing got damaged.

So today I was checking the PCV valve and swapped it out because I think the one that I had installed was bad because air could go both ways. I started up the car and was gonna go test drive under boost to make sure, but as it was warming up I noticed a little smoke from under the manifold cover and if you reved it a little then a little more smoke would start.

So after taking the heat shield off I noticed what looks like oil on one of the bolts that hold the turbo to the manifold and it almost looks like it's leaking oil out of this bolt. But I can really tell because when I checked again with the heat shield off it looked like there might be smoke rolling up from the turbo too. I was just wonder if anyone has see something like this and what are some good next steps?

I'll add some pictures and a video too.

Clean it off with brakes parts cleaner and see if it comes back. When the dipstick pops out, it sprays oil everywhere. It could be residual oil from that.
