2G Boost leak

[Rgst99]

Im doing a boost leak test on my 2g, it's leaking from two areas, my j pipe around the actual screw and on the BISS screw, how do I go about fixing the BISS screw leak or is that normal? It looks like it's screwed all the way down, I haven't touch it. Also how do I stop the leaks from the pipe screws. I'm a noobie anything will be helpful, I'll attach a quick video also. Thankshttps://www.youtube.com/watch?v=3yJ64qCFeGY

Video link seems to be amiss. BISS seals with an o-ring. The o-ring is a common size & can be found from many places like Home Depot, a Harbor Freight o-ring metric kit, etc. Count the number of turn to bottom the BISS before removing so you can reinstall to the same & not need to reset it. My turbo doesn't have a J-pipe but many will use a thin layer of RTV to seal these. There may be a gasket but I don't know.

Awesome thank you, I'll start looking for the one ring, I also uploaded the video again

Both are common locations to leak.
As for the leak from the BISS, as @Mello said above, just replace the tiny o-ring in the pic below. That would probably fix the leak. Do not apply any sealant or RTV on the BISS screw. You will regret.
As for the J-pipe, remove the J-pipe and check the gasket and the flange flatness. It's common that some J-pipe flange is not flat enough, even new. If that's the case, just sand or file the flange surface to make it as flat as you can and apply a bit of RTV on gasket in case if it still leaks.
