At least you don't have to pull the turbo, right? On my old turbo Volvo, the return pipe was a one-piece deal, which meant "off comes the manifold" when it started leaking. Luckily the exhaust manifold studs snapped off on a pretty regular basis, and I replaced the o-ring at the bottom end of the pipe every time I had the manifold off to change the studs (I drove the car a little too hard). The only time I had a leak was when I boogered up the o-ring during installation. It leaked pretty good, then!
