Can't Stop Smoking HELP!!!!

id really appreciate any advise thanks.........im running a t3t04e on a 98 gsr......am also running a fmu, and fuel pump...on stock injectors and about 7 to 8 psi. I've had this setup for about a year and a half, but all of a sudden i've started smoking it looks like by where the turbo connects with the manifold and it looks whitish....at first i thought it was a leaking downpipe, but i changed that and tightened the turbo to mani bolts and its still smoking up a storm.....any ideass..or tests that i can do to figure it out...thanks.....

did you give a very good visual inspection for cracks?

im pretty sure i didn't see any but i should check again.....but if its not that could there be any other thing causing it??

are you using an adapter between the turbo and manifold?

um not sure what that is....but no im not.....just a gastket.....also someone was telling me it could be the turbo seals? i was looking for a diagram but could not find turbo seals on it...any ideas on that one? thanks....i really need to figure this out its bugging the hell out of me thanks.....
