It really wasn't a big deal to remove my intake/exhaust manifolds and turbo. All of the nuts just spun off, the turbo oil line was a cinch. Even the three nuts that held the exhaust elbow on were easy to remove. If you are worried, soak them all over night. It was a nice opportunity to replace the o-rings and lower gasket on the oil drain tubes too. While the manifold was off I mounted the sensor into the bottom of the exhaust manifold. The gasket set wasn't expensive from Fastlane.
