recently had a turbo rebuilt at 200K and had a struggle during reinstall due to misaligned reassembly by TurboCity. Here is a great trick that I wish I'd discovered much earlier: simply cut the oil supply and return lines at appropriate safe locations away from blower and exhaust manifold, and splice in a small piece of Racequip soft oilline using high pressure hose clamps, reinstallation of the oil supply and return lines to the turbo housing is then a snap.
