Hey im about to rip apart my turbo to replace a leaking exhaust side seal. The turbo is relatively new and i just need to get in and change the seal on the exhaust side causing my oil consumption. My question is, which seal am i going to be looking to replace, and how much do i need to take apart? Heres a diagram so maybe you guys can help me out.

Thanks in advance.

(Turbo is a t3/t4 hybrid turbonetics)
