Leaking Exhaust at Turbo

Hey folks, I seem to be leaking exhaust at the turbo connection visible at the very top of connection to exhaust.. I am new so I'm not sure if this is inlet or after turbo, I believe it is after turbo. The cab cab fills with exhaust when I start, stinks, but clears up when warm. My tailpipe seems to be way smokier, but mostly white/grey white smoke. Power and performance seem fine. I am curious if there is any advice to isolate the leak. I'll probably try re-adjusting the ring clamp at the connection on top. The photo doesnt show the smoke so well, but it blasts from the very back top of turbo, blowing towards passenger seat... Thanks

I think that you will find that the leak is not at that location at all, but lower.
Climb under the truck and look at the rear of the engine. You will see that the up-pipes connected to the manifolds connect to a y-pipe..and this y-pipe has bellows in it that will fail.
Has the truck been worked on recently?

I definitely have not overworked it lately. Except for a month straight of -30 c temps. I can actually feel the leak blasting right from the top of the ring clamp where the bolt is. Ibi put my hand between it and the turbo i don feel it. Im going to loosen it, try to seat it better, turn the ring slightly and re tighten. Im hoping it just loosened and jiggled out of place without marring the mating surfaces. Ill look below a well at y pipe

Worked ON, not worked hard.
Reason i ask is because the y-pipe bellows become fragile over time and if someone worked on the engine recently and moved those around, that would explain the failure.
Also, if the turbo was removed, I would bet the problem was on the other side of the turbo..but more about that in a second.

The spot you are looking at is after the turbo, the "downpipe," and leaks there are pretty uncommon. There is a tab on the downpipe that helps with alignment. It pretty much goes right together without a problem.

The exhaust connection before the turbo, on the other hand, can be a real bear at times to get right...and that will leak like nobodies business. It can sound like (description courtesy of my wife when I had this problem) a streetsweeper on steroids.

As far as i know nothing ha been worked on except new alternator. I can see black soot below the turbo/ downpipe connection so you may be right. Things sound normal and as far as i can tell power/function is good. Like i daid more smoke in exhaust than normal( white/grey). Do you have to take turbo out to check y pipe?
